Company B charges $30 per hour and a $150 equipment fee. Let A represent
the amount Company A would charge for t hours of landscaping, and let B
represent the amount Company B would charge for t hours of landscaping.
Write an equation for each situation, in terms of t, and determine the interval
of hours, t, for which Company A is cheaper than Company B.
A=
B=

Answers

Answer:

Step-by-step explanation:

A= 40t + 100

B= 30t + 150

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:

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.

30/5 = 6 = 1/5 of 30

4 x 6 = 24 cookies were oatmeal

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:

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

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

B is NOT CORRECT because they U.S still is it or else it would not be in the chart
C is CORRECT because you would have to add up all the energy source and minus it from 100. Which would add up to 77, and subtracting it from 100 is 23%
D is CORRECT because if you turn the paper/picture, there is a right angle which means it’s 90 degree
C is CORRECT because if you add nuclear and renewable up which is 15, that is smaller then 23.
