Jose buys a bag of cookies that contains 6 chocolate chip cookies, 8 peanut butter cookies, 9 sugar cookies and 8 oatmeal cookies.
What is the probability that Jose reaches in the bag and randomly selects a peanut butter cookie from the bag, eats it, then reaches back in the bag and randomly selects a chocolate chip cookie?
approximately 5% of the time. In decmial form, it is 0.0516129032. If it is in fraction from, then it is 8/155. To explain, you find the total number of cookies. Then you find the number of peanut butter cookies and put that as the numerator over the total as the denominator. After that, you find the number of cookies left after Jose eats one cookie. That becomes the denominator and then find the amount of chocolate chip cookies ib the bag and put it over that total. Multiply both fractions together to get this answer.
The probability that Jose first selects a peanut butter cookie and then a chocolate chip cookie from a bag of 31 cookies is 8 out of 155.
Explanation:This problem is a question of probability, which is a branch of Mathematics. Probability determines how likely an event is to occur out of the total number of possible outcomes. We'll calculate it step by step:
First, we calculate the total number of cookies. Jose has 6 chocolate chip cookies, 8 peanut butter cookies, 9 sugar cookies and 8 oatmeal cookies. We add all these up to get the total number of cookies, which is 31 cookies.Then, Jose first selects a peanut butter cookie. The probability of this happening is the number of peanut butter cookies (8) divided by the total number of cookies (31). We simplify this to 8/31.After eating the peanut butter cookie, the total number of cookies is now 30 and the number of chocolate chip cookies remains 6. Thus, the probability of selecting a chocolate chip cookie now is 6/30, which simplifies to 1/5.Now, we multiply the two probability values to get the overall probability: 8/31 * 1/5 = 8/155. So, the probability that Jose first selects a peanut butter cookie and then a chocolate chip cookie is 8 out of 155.Learn more about Probability here:https://brainly.com/question/32117953

evaluate f(x) when x = -10
So, when x = -10.
If you notice, -10 is NOT in the domain (the domain is (-3,13))
so, there is no solution.
Answer: -24
Step-by-step explanation:
Step one :
For the first equation
Given that x=-10
F(x) =2x-4 if 3<x<10
x exists in this domain
Substituting x in the equation we have
F(-10)=2(-10)-4
F(-10)= -20-4
F(-10)=-24
Step two :
For the second equation
Given that x=-10
F(x) =x²-+3 if 10<=x<13
x does not exist in this domain
A car is traveling 75 kilometers per a
Hour.how many meters does the car travel in one minute?
One hour = 60 minutes
If it is travelling at 75 kilometers per hour, we can divide 75 by 60 to find out how fast it can travel in one minute.
75/60 = 1.25
The car can travel 1.25 kilometers per minute.
However, the questions is asking how many meters it travels in one minute.
A kilometer is 1000x the size of a meter.
Thus, if we multiply 1.25 by 1000x we'll get the amount of meters.
1.25 * 1000 = 1250
The car travels 1250 meters in one minute.
Final answer:
A car traveling at 75 km/h covers 1,250 meters in one minute by converting the speed to meters per hour and then dividing by the number of minutes in an hour.
Explanation:
To convert the car's speed from kilometers per hour to meters per minute, we can use the following conversion factors: There are 1,000 meters in a kilometer and 60 minutes in an hour. Therefore, if a car is traveling at 75 kilometers per hour, we can calculate the distance it travels in one minute as follows:
First, convert the speed to meters per hour: 75 km/h * 1,000 m/km = 75,000 m/h.Then, convert meters per hour to meters per minute: 75,000 m/h ÷ 60 min/h = 1,250 meters per minute.So, a car traveling at 75 kilometers per hour travels 1,250 meters in one minute.
is -5^2 equal to (-5)^2?
A. Yes, because they both equal -25
B. Yes, because they both equal -10
C. Yes, because they both equal 25
D. No, because -5^2 equals -25 and (-5)^2 equals 25
The correct answer is:
D. No, because [tex]\(-5^2\)[/tex] equals -25 and [tex]\((-5)^2\)[/tex] equals 25.
To evaluate the expression [tex]\( -5^2 \)[/tex] and [tex]\( (-5)^2 \)[/tex], we need to understand the order of operations.
According to the order of operations (PEMDAS/BODMAS), exponentiation takes precedence over negation.
So, [tex]\( -5^2 \)[/tex] means [tex]\( -(5^2) \)[/tex], which equals -25.
On the other hand, [tex]\( (-5)^2 \)[/tex] means [tex]\( (-5) \times (-5) \)[/tex], which equals 25.
Therefore, [tex]\( -5^2 \)[/tex] is not equal to [tex]\( (-5)^2 \)[/tex].
The correct answer is option D.

Two angles are complementary. The first angle is 2x degrees. The second angle is (x+30) degrees. Determine the larger angle
larger angle = 50°
complementary angles sum to 90° , hence
2x + x + 30 = 90
3x + 30 = 90 ( subtract 30 from both sides )
3x = 60 ( divide both sides by 3 )
x = 20
thus 2x = 2 × 20 = 40° and x + 30 = 20 + 30 = 50°
the larger angle is x + 30 = 50°
Line WY is dilated to create line W'Y' using point Q as the center of dilation. What is the scale factor? Given that QY' = 4.125, what is QY?
Answer:
1.2.75
2.1.5
Step-by-step explanation:
I just did it
The scale factor is determined by the ratio of the lengths of corresponding sides of two similar figures. To find QY, divide QY' by the scale factor.
Explanation:The scale factor is the ratio of the lengths of corresponding sides of two similar figures. In this case, line WY and line W'Y' are similar figures, and the scale factor is determined by the ratio of their lengths. The scale factor can be calculated by dividing the length of W'Y' by the length of WY. Given that QY' = 4.125, the scale factor can be determined by dividing QY' by QY. So, the scale factor is 4.125/QY. To solve for QY, divide QY' by the scale factor: QY = QY'/scale factor. Therefore, QY = 4.125/(4.125/QY) = (4.125*QY)/4.125 = QY.

if prices increase at a monthly rate of 1.4% by what percentage do they increase in a year?
Prices increase by approximately 18.17% in a year if they rise at a monthly rate of 1.4%.
The given monthly rate of 1.4% can be represented as 1.014 in decimal form (1 + 0.014).
To calculate the total increase over a year, we need to compound this monthly rate for 12 months since there are 12 months in a year. We can use the formula for compound interest to find the overall increase:[tex]\[A = P(1 + r)^n\][/tex]
Where:
[tex]\(A\)[/tex] = the final amount after [tex]\(n\)[/tex] periods (in this case, a year),
[tex]\(P\)[/tex] = the initial price (100% or 1 in decimal form, as it's the starting point),
[tex]\(r\)[/tex] = the monthly rate in decimal form (1.4% or 0.014), and
[tex]\(n\)[/tex] = the number of periods (12 months).
Plugging in the values:
[tex]\[A = 1 \times (1 + 0.014)^{12}\][/tex]
[tex]\[A = 1 \times 1.1771\][/tex]
[tex]\[A \approx 1.1771\][/tex]
The final amount [tex](\(A\))[/tex] represents the price increase over the year. To express this as a percentage, we subtract 1 from [tex]\(A\)[/tex] and then multiply by 100:
[tex]\[Price \, Increase \, Percentage = (A - 1) \times 100\][/tex]
[tex]\[Price \, Increase \, Percentage = (1.1771 - 1) \times 100\][/tex]
[tex]\[Price \, Increase \, Percentage \approx 18.17\%\][/tex]
Therefore, prices increase by approximately 18.17% in a year if they rise at a monthly rate of 1.4%.

whats 20 divided by 3
Answer:
I did this on a Calc. but it is 6.666667
Step-by-step explanation:
Calculator
To divide 20 by 3, we use long division. The quotient is 6 remainder 2, or 6.67 as a decimal.
Explanation:To divide 20 by 3, we can use long division. The divisor, 3, goes into the first digit of the dividend, 2, once. We then multiply 3 by 1, which equals 3, and subtract that from 2. The remainder is 2. We bring down the next digit, 0, and the divisor goes into 20 six times. We then multiply 3 by 6, which equals 18, and subtract that from 20. The remainder is 2. Since there is no longer a digit to bring down, we have our final answer: 20 divided by 3 equals 6 remainder 2, or 6.67 as a decimal.

The answer you are looking for is M = -18.
To find this answer, you first distribute 9 into the parenthesis (m + 4). Once you've distributed, you should be left with 9m + 36 = 7m. Next, you subtract 9m from both sides. This will give you 36 = -2m. Finally, divide both sides by 2. Thus giving you a final answer of M = -18.

Answer:
You can watch 13 movies
Step-by-step explanation:
Cost of Carl's Cable Company:
Monthly service = $55For 1 paper view movie = $4Cost of Teleview Cable Company
Monthly service = $110Lets take that you watch [tex]x[/tex] paper view movies per month.
Then the cost of paper view movies = $[tex]4*x[/tex]
Now we can calculate the total cost of cable TV if you watch [tex]x[/tex] paper view movies per month.
Total cost = Monthly service + Paper view movie cost
=[tex]55+4x[/tex]
Now we can write an inequality for the Cost of Car's Cable Company cost being less than Teleview as follows;
[tex]55+4x≤110[/tex]
Now we can solve this inequality and find [tex]x[/tex] the number of movies you can watch so that the Cost of Carl's cable company will be less than teleview.
[tex]55+4x≤110[/tex]
=[tex]4x≤110-55[/tex]
=[tex]4x≤55[/tex]
=[tex]x≤13.75[/tex]
Therefore, if you watch less than 13.75 movies per month the cost of Carl's cable company cost will be less than Teleview.
So you can watch 13 movies (Number of movies has to be a whole number)
