The table shows six random samples from two corn fields that were fertilized with two different types of fertilizers. Based on the
mean of the data sets, which statement is true?
Fertilizer A produced a 5% greater yield
Fertilizer B produced a 5% greater yield
Fertilizer A produced a 24% greater yield
Fertilizer B produced a 24% greater yield

The Table Shows Six Random Samples From Two Corn Fields That Were Fertilized With Two Different Types

Answers

Answer 1

Answer:

Step-by-step explanation:

fertilizer b produced a 24% greater yield

mean yield fertilizer a = 20.5

mean yield fertilizer b = 25.5

thus,  

25.5 − 20.5  

20.5

= 0.2439 ≈ 0.24 or 24%

Answer 2

Answer:   D    Where B produced 24% greater yield is the Answer.

Step-by-step explanation:

B produced a 24%  greater yield as 24% of 25 = 4

4 is found when we deduct it from B to find A as smaller.

A= 122.90/6=20.48 mean

B =152.1/6 = 25.35 mean

There are 3 red balls, 5 green balls, and 1 yellow ball in a hat. If you draw the yellow ball, you gain $10. If you draw any of the red balls, you gain $4. If you draw a green ball, you lose $3. If you were to play this game 25 times, replacing the drawn ball each time, how much money can you expect to gain or lose?

Answers

Answer:

19.44

Step-by-step explanation:

We have the following information:

3 red balls, 5 green balls, and 1 yellow ball

In total there are 3 + 5 + 1 = 9 balls.

We calculate the probability of each:

Network: 3/9

Green: 5/9

Yellow: 1/9

Each one corresponds a price in profit or losses:

Network: 4

Green: -3

Yellow: 10

So in total it would be the sum of the multiplication of the probability and the price and then multiply everything by 25:

(4 * 3/9 + -3 * 5/9 + 10 * 1/9) * 25 = (0.777) * 25

= 19.44

What is the solution of the inequality shown
below?
c+2 < -1

Answers

Answer: c < -3

Step-by-step explanation: To solve for c in this inequality, your goal is the same as it would be you were solving an equation, to get c by itself on one side of the inequality.

Since 2 is being added to c, subtract

2 from both sides of the inequality.

On the left, the +2 and -2 cancel out

and on the right, -1 - 2 is -3.

So we end up with c < -3.

The following box plot shows points awarded to dance teams that competed at a recent competition:
Which dot plot best represents the box plot data?

Answers

Answer:

C

Step-by-step explanation:

In the box plot we can see that

minimum points awarded: 0maximum points awarded: 100

then, options B and D are incorrect

The median in the box plot is 70. In option A, the median is 95, and in option C, the median is 70.

In option C, also, Q1 is located at 50 (like in the box plot), and Q3 is located at 95 (like in the box plot)

The dot plot that best represents the box plot data is: C.

The minimum, maximum, and median value of a a data set can easily be determined when the data points are plotted on a box plot or dot plot.

Thus, for the box plot, we have the following:

Minimum = 0Maximum = 100Median = 70

Find the dot plot that has the above values as same with the given box plot:

The dot plot in option C has minimum of 0, maximum of 100, and median of 70, therefore, the dot plot that best represents the box plot data is: C.
