Solve the four problems below. Which of the following problems can be solved by finding ? 3 divided by 1/2
a. Shauna buys a three-foot-long sandwich for a party. She then cuts the sandwich into pieces, with each piece being 1/2 -foot long. How many pieces does she get?
b. Phil makes 3 quarts of soup for dinner. His family eats half of the soup for dinner. How many quarts of soup does Phil's family eat for dinner?
c. A pirate finds three pounds of gold. In order to protect his riches, he hides the gold in two treasure chests, with an equal amount of gold in each chest. How many pounds of gold are in each chest?
d. Leo used half of a bag of flour to make bread. If he used 3 cups of flour, how many cups were in the bag to start?
Answer:
[tex](a)=6\\(b)=1\ \frac {1}{2}\\(c)=1\ \frac {1}{2}\\d=6[/tex]
Step-by-step explanation:
(a)
3 ft long when divided into half ft each will be
3ft ÷1/2 ft
We change the ÷ to × then the second part is reciprocated hence
3ft÷1/2= 3ft×2/1=6 pieces
(b)
The question requires us to get the differences. Initially, Phil makes 3 quarts of soup but the family takes only half of the original quantity to mean Phil remains with the other half.
Therefore, half of 3 is 3×1/2=3/2= 1.5 or 1 1/2
(c)
Hiding 3 pounds of gold into two equal sections means 3 is divided by 2
3÷2=1.5 or 1 1/2
(d)
If half, 0.5 represent 3 cups then full quantity represent x
0.5=3 cups
1=x

A relative frequency table is made from data in a frequency table.
Relative Frequency Table: A 4-column table with 3 rows. The first column has no label with entries likes S, T, total. The second column is labeled U with entries 26%, 21%, 47%. The third column is labeled V with entries 42%, k, 53%. The fourth column is labeled total with entries 68%, 32%, 100%.
What is the value of k in the relative frequency table? Round the answer to the nearest percent.
2%
11%
20%
33%
Answer:
k = 11 let me know if you don't understand how I got this.
Step-by-step explanation:
I'm gonna write it out
U V total
S 26 42 68
T 21 k 32
Total 47 53 100
So, you want to look at the column and row labeled total, this is the key. for the row total, it sums up everything in the column above it. so for the u column, the total value is 47 while the two values above it are 26 and 21. These two values sum to 47. This is the same for all other columns, and you can use the same reasoning with the total column as well summing rows.
This gives you two ways to solve for k. either 21 + k = 32 or 42 + k = 53. Either way gets you the answer k = 11
The value of k in the relative frequency table is 11%.
What is relative frequency?The ratio of the frequency of a particular event in a statistical experiment to the total frequency.
U V total
S 26 42 68
T 21 k 32
Total 47 53 100
As, when we add the column data 26+ 21 = 47 which shows that the total consist of sum of column data.
So,
21 + k = 32

The sum of the present ages of a father and his son is 80 years. When the
father's age was equal to the present age of the son, the sum of their ages
would be 40 years. Find their present ages.
Answer:
Father=60
Son=20
Step-by-step explanation:
Let the father's age be x
Let the son age be y
Present age of them
X+y=80...(1)
Since the father's age equals to the present age of the son
Y+y=40
2y=40....(2)
Make y the subject of formula by dividing both sides by 2
Y=20
Substitute the value for x into (1)
20+x=80
Substrate 20 from both sides
X=60
Therefore the father's age is 60 and the son's age is 20
What is the area of this irregular figure knowing that the formula for the area of a rectangle is l x w.
Answer:
35
Step-by-step explanation:
5+5+10+3+2+7+3=35
Answer:
The area is 42
Step-by-step explanation:
First you have to divide the figure into three rectangles
The first one has
Lenght=10
Width=5-2=30
Area=l x w=10x30=30
The other two are equivalent in lenght and width that means that if if we find the area of one we must multiply by 2 to find the other.
Rectangles 2 and 3
Lenght=3
Width=2
Area of one of them=3x2=6
Both rectangles=6x2=12
Now, we add everything up
Total Area=12+30=42

2.75 cups of water mixed with 3.5 cups of pancake mix will make 19 pancakes. How much water is needed if there is only 1.5 cups of pancake mix left?
Answer:
You would need .75 cups of water (or 3/4 cups) if there is only 1.5 cups of pancake mix left
Step-by-step explanation:
So the ratio of water to pancake mix is 2.75 : 3.5 (which makes 19 pancakes)
To get from 3.5 cups of pancake mix to 1.5 cups of pancake mix you would subtract 2 cups. Since this is a ratio, you would not only subtract 2 cups from the pancake mix, but also from the water. 2.75 - 2 = .75 Therefore, you would need .75 cups of water (or 3/4 cups) if there is only 1.5 cups of pancake mix left. Hope this helps!
Answer:
1 5/28 cups of water
Step-by-step explanation:
Water : pancake mix
2.75 : 3.5
X : 1.5
2.75/X = 3.5/1.5
X = 2.75 × 1.5/3.5
X = 33/28 or 1 5/28 cups

Using a 16-sided number cube, what is the probability that you will roll a multiple of 4 or an odd prime number? The number 1 isn't an odd prime. Round to three decimals.
A. 0.625
B. 0.250
C. 0.563
D. 0.688
================================================
Explanation:
E = event space
E = set of outcomes we want to happen
E = rolling a multiple of 4 or rolling an odd prime number
E = {4,8,12,16 3,5,7,11,13}
n(E) = number of items in set E
n(E) = 9, (four multiples of 16+five ways to roll odd prime number)
-----
S = sample space
S = set of all possible outcomes (whether we want them to happen or not)
S = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}
n(S) = number of items in set S
n(S) = 16
-----
P(E) = probability of event space occurring
P(E) = probability of rolling a multiple of 4 or rolling an odd prime number
P(E) = n(E)/n(S)
P(E) = 9/16
P(E) = 0.5625
P(E) = 0.563

Based on Liz’s results, the experimental probability of the coin landing heads up is_____. The theoretical probability is than the experimental probability in this experiment________.
Answer:
50% or 50/100 or 25/50 40% or 40/100 or 20/40MoreStep-by-step explanation:
The theoretical probability is more than the experimental probability in this experiment
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the number of times the coin is flipped be n = 50
And , the number of times the heads is shown = 20 times
The number of times the tails is shown = 30 times
The theoretical probability of a coin being head or tail P ( A ) = 50 %
So , the experimental probability of being a head is P ( B ) = 20/50
P ( B ) = 40/100 = 40 %
Therefore , P ( A ) > P ( B )
Hence , theoretical probability is more

What, approximately, is the mean weight for babies born
during this two-month period?
As a nurse in a maternity ward, you are tracking the
weights of newborn babies. In the month of August, 360
babies are born, with a mean weight of 8.1 pounds. In the
month of September, 291 babies are born, with a mean
weight of 7.8 pounds.
7.83 pounds
7.93 pounds
7.95 pounds
7.97 pounds
7.99 pounds
Final answer:
The approximate mean weight for babies born during the two months of August and September is calculated using a weighted average, and it is approximately 7.97 pounds.
Explanation:
To find the mean weight of the babies born during the two months, we can use the weighted average formula which takes into account the different numbers of babies born in each month and their respective mean weights.
The formula for the weighted mean is as follows:
Weighted mean = (Sum of weights × their respective frequencies) / (Total sum of frequencies)
Calculate the total weight for August: 360 babies × 8.1 pounds = 2916 pounds.Calculate the total weight for September: 291 babies × 7.8 pounds = 2269.8 pounds.Add the weights from both months: 2916 pounds + 2269.8 pounds = 5185.8 pounds.Add the number of babies from both months: 360 babies + 291 babies = 651 babies.Divide the total weight by the total number of babies: 5185.8 pounds ÷ 651 babies = approximately 7.97 pounds.Therefore, the approximate mean weight for the babies born during August and September is 7.97 pounds.
Let f(x) = 8x + 5 and g(x) = -2x - 4 Find the value of f(2) + g(5) *
Answer: lock down
Step-by-step explanation: f(x)= 8x2 + 5=21--> f(x)=21
g(x)= -2x5 - 4=-14--> g(x)=-14
f(2)+g(5) = 7
Step-by-step explanation:
Given,
f(x) = 8x+5
g(x) = -2x-4
To find f(2)+g(5)
Now,
f(2) means putting the value of x = 2 in f(x)
g(5) means putting the value of x = 5 in g(x)
f(2) = 8(2)+5 = 21
g(5) = -2(5)-4 = -14
Hence,
f(2)+g(5) = 21-14 = 7
