Mark has $16 to buy lunch for himself and his sister. He wants to buy at least one sandwich and one bag of chips. Sandwiches cost $6 and chips cost $1.50. Write inequalities to represent the constraints on the number of sandwiches and bag of chips Mark could buy. Can Mark buy 2 sandwiches and 2 bag of chips?
Answer:
Victor runs a small sandwich shop. He decides to start offering bags of chips to his customers. He finds a supplier where he can buy chips for $0.30 per bag. Victor needs to determine how much to charge for the chips at his shop. He does some research by talking to other nearby sandwich shop owners. The table below shows their sales per week for two different prices. (The values are: 150 bags sold, for $1.00 per bag, and 350 bags sold, for $0.50 per bag.) Victor believes that there is a linear relationship between the number of bags sold and the price. Victor wants to price the bags of chips so that he will maximize his profits. Determine the price Victor should charge for a bag of chips. Use the equation P(x)=R(x)-C(x), where P(x) represents profit, R(x) represents revenue, and C(x) represents cost. Each is a function of the number of bags of chips sold, x. Round your answer to the nearest nickel.

Determine whether the relation shown here is a function.
Answer:
this is not a function because the 2 is used twice
Answer: "D"
Step-by-step explanation: The mapping diagram shown here would not represent a function. When looking at a mapping diagram, there is one key thing we need to look for to identity if the relation is a function. We need to look and see if an input has two different outputs. When looking at the mapping diagram, the input (2) has two completely different outputs which makes this hard to interpret data. This means that the relation is not a function.
When dealing with mapping diagrams, remember that an input can only have one corresponding output and if it has more than one, then this would not represent a function.
Reinhardt Furniture Company has 40,000 shares of cumulative preferred 2% stock, $150 par and 100,000 shares of $5 par common stock. The following amounts were distributed as dividends: Year 1 $70,000 Year 2 200,000 Year 3 320,000 Determine the dividends per share for preferred and common stock for each year. If an answer is zero, enter '0'. Round all answers to two decimal places.
Answer:
for year 1
common stock = $1.75 per share
preferred stock = Zero
for year 2
common stock = $4.25 per share
preferred stock = $0.3 per share
for year 3
common stock = $3 per share
preferred stock = $2 per share
Step-by-step explanation:
step 1
preferred stock value = (40000 shares * $150) = $6000000
common stock value = (100000 shares * $5) = $500000
step 2
For year 1:
Dividend on preferred stock;
[tex]\frac{6000000 * 2}{100}[/tex] = $120000
But total dividend in the question was $70000 therefore total amount of dividend on cumulative preferred stock is $70000.
hence, dividend per share
[tex]= \frac{70000}{40000 shares}[/tex] = $1.75 per share
Dividend on common stock;
70,000 - 70,000 = Zero
as total dividend distributed in year 1 is insufficient for cumulative preferred stock therefore no dividend will be paid on common stock.
For year 2:
Dividend on cumulative preferred stock;
[tex]\frac{6000000 * 2}{100}[/tex]= $120000
extra dividend of year 1 ($120000 - $70000) = $50000
Thus total dividend on cumulative preferred stock
($120000 + $50000) = $170000
So dividend per share
[tex]\frac{170000}{40000\ shares}[/tex]= $4.25 per share
Dividend on common stock;
($200000 – $170000) = $30000
dividend per share
[tex]\frac{30000}{100000\ shares}[/tex] = $0.3 per share
For year 3:
Dividend on cumulative preferred stock;
[tex]\frac{6000000 * 2}{100}[/tex] = $120000
total dividend on cumulative preferred stock $120000
dividend per share
[tex] \frac{120000}{40000 shares}[/tex] = $3 per share
No dividend was extra in the year 2 therefore only available dividend of this year will be paid.
Dividend on common stock;
($320000 – $120000) = $200000
dividend per share
[tex]\frac{200000}{100000\ shares}[/tex]= $2 per share
According to a study in a medical journal, 202 of a sample of 5,990 middle-aged men had developed diabetes. It also found that men who were very active (burning about 3,500 calories daily) were a third as likely to develop diabetes compared with men who were sedentary. Assume that one in 10 middle-aged men is very active, and the rest are classified as sedentary. What is the probability that a middle-aged man with diabetes is very active? (Round your answer to four decimal places.)
To find the probability that a middle-aged man with diabetes is very active, we need to use conditional probability. We calculate the probability of a middle-aged man being very active and the probability that a middle-aged man has diabetes. Then we use these probabilities to find the conditional probability of being very active given diabetes.
Explanation:To find the probability that a middle-aged man with diabetes is very active, we need to use conditional probability. Let's first calculate the probability of a middle-aged man being very active:
P(very active) = 1/10
The remaining probability would be for men who are sedentary:
P(sedentary) = 1 - P(very active) = 9/10
Now we can calculate the probability that a middle-aged man with diabetes is very active using conditional probability:
P(very active | diabetes) = (P(very active) * P(diabetes | very active)) / P(diabetes)
Since the question states that men who are very active are a third as likely to develop diabetes compared to men who are sedentary, we can calculate:
P(diabetes | very active) = 202/5990
P(diabetes) = (202/5990 * 1/10) + (P(diabetes | sedentary) * 9/10)
Substituting the values, we can calculate the probability that a middle-aged man with diabetes is very active:
P(very active | diabetes) = (1/10 * 202/5990) / ((202/5990 * 1/10) + (P(diabetes | sedentary) * 9/10))

The probability that a middle-aged man with diabetes is very active is:
[tex]\[ {0.0356} \][/tex].
Given data:
- [tex]\( P(A) = \frac{1}{10} = 0.1 \)[/tex](probability of being very active)
- [tex]\( P(S) = \frac{9}{10} = 0.9 \)[/tex] (probability of being sedentary)
- [tex]\( P(D | S) \)[/tex] (probability of developing diabetes given sedentary) is not directly given, but we can deduce it using the provided data and the fact that the risk of diabetes for active men is a third of that for sedentary men.
- Total probability of developing diabetes, [tex]\( P(D) = \frac{202}{5990} \approx 0.0337 \)[/tex]
First, we need to calculate [tex]\( P(D | A) \) and \( P(D | S) \)[/tex]:
Since active men are a third as likely to develop diabetes compared to sedentary men:
[tex]\[ P(D | A) = \frac{1}{3} P(D | S) \][/tex]
Using the law of total probability for P(D) :
[tex]\[ P(D) = P(D | A)P(A) + P(D | S)P(S) \][/tex]
Substitute the given values and the relationship between P(D | A) and P(D | S):
[tex]\[ 0.0337 = \left( \frac{1}{3} P(D | S) \right)(0.1) + P(D | S)(0.9) \][/tex]
Solve for P(D | S) :
[tex]\[ 0.0337 = \frac{1}{30} P(D | S) + 0.9 P(D | S) \]\[ 0.0337 = 0.0333 P(D | S) + 0.9 P(D | S) \]\[ 0.0337 = (0.0333 + 0.9) P(D | S) \]\[ 0.0337 = 0.9333 P(D | S) \]\[ P(D | S) = \frac{0.0337}{0.9333} \approx 0.0361 \][/tex]
Now calculate P(D | A) :
[tex]\[ P(D | A) = \frac{1}{3} P(D | S) = \frac{1}{3} \times 0.0361 \approx 0.0120 \][/tex]
Next, apply Bayes' theorem to find P(A | D) :
[tex]\[ P(A | D) = \frac{P(D | A) P(A)}{P(D)} \]\[ P(A | D) = \frac{0.0120 \times 0.1}{0.0337} \]\[ P(A | D) = \frac{0.0012}{0.0337} \approx 0.0356 \][/tex]
A caterer charges $800 for a party of 25 guests. For a party of 60 guests, the cost is $1,430. Enter a linear model that represents the total cost, C, as a function of g, the number of guests at a party.
Answer:
C = 18g +350
Step-by-step explanation:
The 2-point form of the equation of a line is useful for this. For points (x1, y1) and (x2, y2), the equation is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
For points (25, 800) and (60, 1430), the line is ...
y = (1430 -800)/(60 -25)(x -25) +800
y = 630/35(x -25) +800
y = 18x +350
Using the variables required by the problem statement, this is ...
C = 18g +350
Good Stuff is giving away free pens to each of the first 200 people who come in the store today. In the first hour, they gave away 25% of the pens. How many is this?
Answer:
50 pens
Step-by-step explanation:
x= 25 percent of 200
25/100 times X/200
Cross multiply them and you get
100x=5000
X=5000/100
X=50
25 percent of 200 is 50.

A rectangle has side lengths of (2x-5) meters and (2x+6) meters. Write a linear expression in simplest form to represent the perimeter. Find the perimeter if the value of x is 12 meters
Answer:
P = 8x + 2
P = 98 when x = 12
Step-by-step explanation:
the perimeter is 2 times width + length
P = 2(w + l)
w = 2x - 5
l = 2x + 6
replacing both terms in the perimeter:
P = 2(2x - 5 + 2x + 6)
P = 2(4x + 1)
P = 8x + 2
Evaluating P for x = 12
P = 8(12) + 2
P = 98

The use of the relative frequency method to develop discrete probability distributions leads to what is called a a. binomial discrete distribution. b. non-uniform discrete distribution. c. uniform discrete distribution. d. empirical discrete distribution.
Answer:
d. empirical discrete distribution
Step-by-step explanation:
Empirical refers to what you observe, in this case the relative frequency
Discrete probability distributions is what you are trying to develop.
a, b and c are different forms an empirical discrete distribution can take. You could say that a,b and c are "types" of the "empirical discrete distribution"
The use of the relative frequency method leads to an empirical discrete distribution, which reflects observed frequencies in a sample and is distinct from theoretical models like the binomial distribution.
The use of the relative frequency method to develop discrete probability distributions leads to what is known as an empirical discrete distribution. This method involves determining probabilities based on the frequency of observed outcomes in a sample. In contrast, other discrete distributions such as the binomial distribution, hypergeometric distribution, and Poisson distribution are based on mathematical models with specific properties and assumptions beyond empirical observation.
An empirical discrete distribution captures the observed frequencies of outcomes in a sample and uses these frequencies as probabilities. It does not assume a specific theoretical distribution model, unlike the uniform distribution which assumes each outcome is equally likely, or the binomial distribution which is based on a fixed number of independent trials with a constant probability of success.

Swifty Corporation started the year with total assets of $300000 and total liabilities of $240000. During the year the business recorded $633000 in revenues, $335000 in expenses, and dividends of $61000. Stockholders’ equity at the end of the year was
a) 275000
b) 363000
c) 305000
d) 297000
Answer:
The answer is d) 297000
Step-by-step explanation:
The stockholders' equity of a company represents the amount of money that will be returned to the accionists if all the assests will be liquidated and the compan'y debt will be paid. So to calculate the Swifty Corporation stockholders' equity at the end of the year you need to add all what enters to the company (assets and revenues) and substract all what goes out (liabilities, expenses and dividends).
- What enters?
The starting assets = $300.000Revenues = $633.000Total incomes = $300.000 + $633.000 = $933.000
- What goes out?
Liabilities = $240.000Expenses = $335.000Dividends = $ 61.000Total expenses = $240.000 + $335.000 + $61.000 = $636.000
Stockholders' equity = Total income - Total expenses
Stockholders' equity = $933.000 - $636.000 = $297.000

On an island where knaves never tell the truth and knights always tell the truth, you meet 3 of the island's inhabitants: Fred, George, and Quincy. You ask Fred, "Are you a knave?" Fred says the answer to the other natives, but you can't hear him. George turns to you and says that Fred denied being a knave. Quincy says Fred is a knave. How many of the three are knaves?
Answer:
There is one knave
Step-by-step explanation:
Let's analyze the two possible scenarios, from the unheard Fred's answer
- SCENARIO 1: Fred is a knave.
If Fred is a Knave, he must have told to the other natives that he wasn't, remember that Knaves will never tell the truth. In that sense, George said that Fred denied being a knave, he would be telling the truth (Fred is a knight) and Quincy said that Fred is a knave, which would also be true (Quincy is a knight too).
-SCENARIO 2: Fred is a knight
If Fred is a knight, he must have told to the other natives that he wasn't a knave, he would be telling the truth. In this case, George would also be telling the truth by ensuring that Fred denied being a knave (Fred is a knight). However, Quincy would be lying to ensure that Fred is a knave. In this scenario Quincy is the knave
In conclusion, in both scenarios, there is only one knave.

E. Statements (1) and (2) TOGETHER are NOT sufficient.
Answer: C
Step-by-step explanation: C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
Total: 1000
20 had fever, so 1000 - 20 = 980 who did not have fever
Total who did not have fever: 980
As 880 not fever and not inflamation, 980 - 880 = 100
So, 100 had inflamation but not fever.

Please help me understand this problem! I don’t understand the methods to understand how to solve it
Answer:
Perimeter at the big rectangle is 156 cm.
Step-by-step explanation:
Let's see how to calculate it.
1. First of all you know that perimeter in the blue one is 20cm, so imagine this:
L (long side); S (short side)
2L + 2S =20
and we consider that L = 4S
So, solving the equation:
2.4S + 2S =20
10S=20
S=20/10
S=2
L=8
2. Side at the gold square is 8, the same at the long side in the blue rectangle. So, if you see on the right side in the big one, we got 2 + 8 + 8 + (?). Take a look to the green. Green square is the gold + a short piece and you can understand the short piece as 2 short sides from the blue. If we give numbers we have 8 + 2 + 2, 12.
Now, 2+8+8+12 = 30cm
3. Let's go to the long side in the big one.
We have long side from blue (8) and as you see, side at the orange square must be side at the yellow + short at the blue, so 8+2 =10. We have four oranges square so 10+10+10+10=40, and +8 =48
4. Now that we have the two sides in the big one, let's find the perimeter with the rectangle formula:
2L + 2S =P
2.48 + 2.30 = 156 cm.
It takes Natasha 33 minutes to walk to the pool from her house. If she rides her bike, it takes her 1/3 of that time. Natasha leaves her house for the pool at 3:12. If she is riding her bike, what time will she arrive
Answer:
She will arrive at 3:23 to the pool.
Step-by-step explanation:
Since Natasha takes 33 minutes to walk through the pool from her house.
Also, if she rides a bike then that time is 1/3 times reduced.
So total time to ride the bike from her house to the pool is [tex]33\times\frac{1}{3}=11 minutes[/tex]
Now, If she leaves the house at 3:12 then she will reach to the pool is 3 hours 12 minutes + 11 minutes = 3 hours 23 minutes = 3:13
Hence, She will arrive pool at 3:23.

On a square gameboard that is divided into n rows of n squares each, k of these squares do not lie along the boundary of the gameboard. If k is one of the four numbers 10, 25, 34, or 52, what is a possible value for n?
To find a possible value for n given the number of squares not along the boundary of a gameboard, set up an equation and solve it using the quadratic formula.
Explanation:The number of squares that do not lie along the boundary of the gameboard can be found by subtracting the number of squares along the boundary from the total number of squares on the gameboard. The total number of squares on the gameboard is n×n, and since there are n squares along each side of the gameboard, the number of squares along the boundary is 4n. Therefore, the number of squares that do not lie along the boundary is n×n - 4n.
Given these equations, we can set up an equation for each possible value of k:
10 = n×n - 4n25 = n×n - 4n34 = n×n - 4n52 = n×n - 4nWe can solve these equations to find the possible values of n. For the first equation, arranging the terms gives us the quadratic equation n×n - 4n - 10 = 0. By solving this quadratic equation using the quadratic formula, we can find the possible values of n that satisfy the equation. Similarly, we can do the same for the remaining equations to find all possible values of n.

125/300 people decided to buy their product but 175 didn't to get the answer for the problem you just divide 175 by 300 which gets you 0.58333... in which you move the decimal place two to the right which gives you 58.3 then that is your percent 55.3%
Answer: There is 58.3% of students that are not convinced.
Step-by-step explanation:
Since we have given that
Number of schools = 300
Number of schools that are convinced to sell their products = 125
Number of schools that are not convinced to sell their products = 300 - 125 = 175
Percentage of schools that are not convinced is given by
(175 ÷ 300) × 100
= 175 ÷ 3
= 58.3 %
Hence, there is 58.3% of students that are not convinced.

Identify Who and What were investigated and the Population of interest. A study found that after a meal, a woman can tell whether a man is married or single by looking at his face. The study involved 40 undergraduate women who were asked to guess the marital status of 80 men based on photos of their face. Half of the men were married, and the other half were single. All held similar expressions in the photos. All the women had eaten the same meal at the time of the test. The result was that the closer a woman was to her last meal, the more accurate her guess.
(A) The 40 married men
(B) The 80 men whose faces were used in this study

Researchers wanted to explore self-esteem in adolescent boys and adolescent girls. Each respondent completed a 10-item self-esteem scale (they chose one rating for each item from a Likert-type scale, 1 = strongly disagree and 5 = strongly agree). The sum of the 10 ratings was each respondent's self-esteem score. Their results were: t = 2.01, d = .90 (40 girls, 40 boys).What statistical test did the researchers use to determine if there was a statisticallysigniFcant di±erence in levels of self-esteem between the boys and the girls?
Answer:
The statistical tests that researchers use to determine if there was a statisticallysignificant difference in levels of self-esteem between the boys and the girls were the T-test and Cohen's d.
Step-by-step explanation:
A statistical test is utilized to evaluate differences between groups (in this case, between boy and girls). The dependent variable was the self-esteem while the independent variable was the sex. A T-test is utilized to establish differences in the mean of two groups. The null hypothesis for a T-test is that means of the groups are the same; the statistical value is t. A Cohen's d test indicates standardized differences between the mean of both groups. It usually accompanies a T-test result; the statistical value is d.
