1. Sara bought cartons of raspberries that cost $1.50 and cartons of blackberries cost $2. Sara spent $11 buying raspberries and blackberries. She bought a total of 6 cartons. How many cartons of blackberries did she buy?​

Answers

Sara brought a total of 5 cartons of blackberries. Since it said that Sara brought 6 cartons and you know that the cost of the blackberries are $2, you multiply 6 with 2 but its 12. But if Sara  brought 2 cartons of raspberries it will be $3. Now you subtract 6 with 2 since you used 2 cartons on raspberries and now multiply $2 with 4 and get 8. 8+3=11, which is exactly how much she needs. This means that Sara brought 4 cartons of blackberries.

One father is 70 inches tall and the residual for his son’s height is 2.5. What is the son’s actual height?

71.7 inches
74.2 inches
76.7 inches
82.3 inches

Answers

Answer: C

Step-by-step explanation:

Since the heights of the men are assumed to be normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = heights of the men.

µ = mean height

σ = standard deviation

From the information given,

µ = 70.7 inches

σ = 2.1 inches

The probability that they have a mean height greater than 71.7 inches is expressed as

P(x > 71.7) = 1 - P(x ≤ 71.7)

For x = 71.7

Since n = 36, then

z = (71.7 - 70.7)/2.1/√36 = 2.86

Looking at the normal distribution table, the probability corresponding to the z score is 0.998

P(x > 71.7) = 1 - 0.998 = 0.002

If there are 22 successes in a sample with a size of 40, what is the sample
proportion?

A. 0.55
B. 0.65
C. 0.44
D. 0.22

Answers

Answer:

A

Step-by-step explanation:

22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.

22/2 = 11

40/2 = 20

Now you have 11/20. Put this in decimal form and you have 0.55

Option A answer is 0.55

What is the proportion of a sample?

The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.

The solution to the given problem

The size of the sample is 40.

There are 22 successes in the sample.

To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55

Hence option A is correct, the proportion is 0.55

Mr. Ramirez baked 25 cookies. 4 fifths of the cookies were oatmeal. How many oatmeal cookies did Mr. Ramirez bake?

Answers

Answer:

20 oatmeal cookies

Step-by-step explanation:

4/5 of 25 is 20

If you are working on proportions, you can do 4/5=x/25

Answer:

24

Step-by-step explanation:

30 cookies, 4/5 are oatmeal

Multiply fractions straight across the equation, numerator times numerator and denominator times denominator.

30/1 x 4/5 = 120/5

Reduce 120/5 by dividing denominator and numerator by 5

120 / 5 = 24/1 = 24 cookies were oatmeal.

OR

30/5 = 6 = 1/5 of 30

4 x 6 = 24 cookies were oatmeal

They made a difference in peoples lives and learned some important life lessons in the process. Organizations, including schools, are actively promoting service for all citizens as a way to be involved, help others, and improve themselves.Service is helping other people and being active in your community. For example, one group of teens planted a community garden with their friends. They grow a variety of vegetables. The garden requires regular care. The teens donate the produce to a local soup kitchen. Workers there use the produce to help feed people in the community. By tending the garden and donating their produce, the teens are actively helping make life a bit better for others in their community.Service is valuable in ways that cannot be measured in dollars. People volunteer or serve others without expecting money or gifts in return. Service is not about earning money. It is not just collecting money to give to a group. It is about action and contributing to the common good. The people who serve as well as those who receive help benefit in many ways that are more important than money or gifts. For example, a soup kitchen provides essential food to people who may otherwise go hungry. The soup kitchen is extremely valuable for those struggling to get enough to eat. Those serving learn about compassion and how helping others can improve life for all.Millions of Americans are making society better for themselves and for others. They are participating citizens in their community, raising up those who are less fortunate. In return, they become better people who can understand the perspectives and needs of others, which are invaluable and important qualities of good citizens.Which sentence is a support detail for paragraph three?
