A.
No conclusion can be made because the experiment is biased.

B.
The range of heights for plants with Fertilizer B is less than Fertilizer A.

C.
Fertilizer B will outperform Fertilizer A every time.

D.
On average Fertilizer A produces a taller plant.

Answers

Answer 1

Answer:

its B

Step-by-step explanation:

Answer 2

Fertilizer B is likely more effective than Fertilizer A.

The correct answer is option C: Fertilizer B will outperform Fertilizer A every time.

What is the mean?

In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the quantity of observations).

To draw a conclusion from the experiment, we need to analyze the data. We can calculate the mean heights of the seedlings for each fertilizer.

For Fertilizer A: (19.8+25.7+29.0+23.2+27.8+31.1+26.5+24.7+21.3+25.6)/10 = 25.67

For Fertilizer B: (23.4+30.1+28.5+26.3+32.0+29.6+26.8+25.2+27.5+30.8)/10 = 28.89

Based on the data, it appears that the seedlings treated with Fertilizer B had, on average, a greater height than those treated with Fertilizer A.

Therefore, we can conclude that Fertilizer B is likely more effective than Fertilizer A.

The correct answer is option C: Fertilizer B will outperform Fertilizer A every time.

Bill earned $10.00 per hour he worked 40 hours at regular rate , 8hours at a time and a half and 8hours double time compute the total wage

Answers

Answer:

Total wage= $680

Step-by-step explanation:

Giving the following information:

Regular wage= $10

One and a half= $15

Double= $20

To calculate the total wage, we need to use the following formula:

Total wage= x*10 + y*15 + z*20

x= normal hours

y=one and a half hours

z= double hours

Total wage= 40*10 + 8*15 + 8*20

What additional information would you need to prove by the HL theorem?

Answers

Answer:

Answer: A   [tex]\overline{TM}\cong \overline{OR}[/tex]

Step-by-step explanation:

The HL Theorem states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.

Triangles TRO and OMT share the hypotenuse, so the first part of the theorem is met.

Both triangles are right because they have an internal angle of 90°, so the second condition is also met.

Since there is no indication of any leg to be congruent to another leg, we need additional information to prove that both triangles are congruent.

One of these two conditions should be met:

Side TM is congruent to side OR, or

Side MO is congruent to side RT.

From the available options, only the first is correct.

C.the average amount spent out of the udget each month
D.the predicted amount of time after which the entire budget will. e spent​

Answers

Answer:

A. the total amount of the budget given to the country

Step-by-step explanation:

In order to know the answer, you have to check what the y-axis represents. In the graph above, it represents the "Budget Remaining," which is expressed in thousands of dollars. On the other hand, the x-axis represents the "Time," which is expressed in months.

Point (0,18) shows the total amount of the budget for the Cultural Events in the country. It starts at 18,000 dollars and decreases as months pass by. This is shown by the graph's "negative slope." This means that as the number of months increases, the amount of money decreases.

$9000 was borrowed from two sources, one that charges 20% simple interest and the other that charges 5% simple interest. If the total interest at the end of 1 year was $1500, how much money was borrowed from each source?

Answers

Answer:

The amount borrowed at 20% simple interest was $7,000, while the amount borrowed at 5% simple interest was $2,000.

Step-by-step explanation:

Let x represents the amount borrowed at 20% simple interest.

Let y represents the amount borrowed at 5% simple interest.

Therefore, the amount borrowed at 5% simple interest will be:

y = 9000 - x ........................... (1)

As a result, we will have:

20%x =  interest at the end of 1 year from the amount borrowed at 20% simple interest

5% * (9000 - x) = 450 - 5%x = interest at the end of 1 year from the amount borrowed at 5% simple interest

Since the total interest at the end of 1 year was $1500, we have:

20%x + 450 - 5%x = 1500

We can now solve for x as follows:

20%x - 5%x = 1500 - 450

15%x = 1050

x = 1050 / 15%

x = 7000

Substituting x = 7000 into equation (1), we have:

y = 9000 - 7000

y = 2000

Therefore, the amount borrowed at 20% simple interest was $7,000, while the amount borrowed at 5% simple interest was $2,000.

a. What is the mistaken assumption here?
b. Why is that assumption incorrect?
c. What do the shoes actually cost now?
d. By what percent should the shoes be decreased in order to have the price
back at $100?
Kk

Answers

Answer:

the customer is wrong

Step-by-step explanation:

when he raised then 50 % they became $150 and then If you do the work 50% of $150 is $75 .

100+%50

150

150-%50

75

The customer is wrong because the new price of the shoe is $75 and not $100.

When the shop owner raises the price of a $100 pair of shoes by 50%, then the new price will be:

= $100 + (50% × $100)

= $100 + $50

= $150

Then, the owner reduces the price by 50%, then the new price will be:

= $150 - (50% × $150)

= $150 - $75

= $75

Therefore, the new price is $75.

The sum of two positive numbers is 37, and their difference is 7. If x and y represent the unknown numbers, which two
equations belong to the system of equations that represents this situation?

Answers

Answer:

C & D. check the image just in case the order changes

Step-by-step explanation:

A system of equations is x + y =37 and x - y = 7 the positive numbers are 22 and 15.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

The sum of the two positive numbers is 37, and their difference is 7.

Let x and y be the numbers:

x > 0 and y > 0

x + y =37

x - y = 7

The above two equations represent the situation where the sum of two positive numbers is 37, and their difference is 7.

After solving the above equation by elimination method:

2x = 44

x = 22

22 - y = 7

y = 22 - 7

y = 15

Thus, a system of equations is x + y =37 and x - y = 7 the positive numbers are 22 and 15.
