A farmer applied different types of fertilizer to two different sections of his watermelon field. At the end of the growing season, the farmer randomly weighed 20 watermelons from each section. The table shows the mean and the mean absolute deviation (MAD) of the weights for each fertilizer.Fertilizer Mean (lb) MAD
1 24 3
2 22 2
Calculate the means-to-MAD ratio. Can the farmer conclude that Fertilizer 1 generally produces heavier watermelons?

Select from the drop-down menus to correctly answer the question.

The farmer (can, cannot) conclude that Fertilizer 1 generally produces heavier watermelons because the distributions of weights for the two fertilizers are (identical, somewhat similar, similar, different).

Answers

Answer 1
Answer: the mean is the average weight.
 the MAD is how spread out the weights are from the mean, the higher the number the more spread out, which means you could have more lower weights than higher weights, of more heavy than light

 so fertilizer 1 had a higher average weight ( 24 is greater than 22)
 and the difference in MAD is only 1 ( 3-2)

so the farmer CAN conclude , because the distribution is SOMEWHAT SIMILAR

The sum of a number and two times a smaller number is 98. The bigger number is 22 less than three times the smaller number. What are the two numbers?

Answers

Answer:

The smaller number is 24 and the larger number is 50.

Step-by-step explanation:

b>a  

b=3a-22, b+2a=98, using b from the left in the right:  

3a-22+2a=98  

5a-22=98  

5a=120  

a=24, and since b=3a-22,  

b=50  

So the smaller number is 24 and the larger number is 50.

Does this table represent a function, why or why not?

Answers

Answer:

a) No, because one x-value corresponds to two different y-values.

Step-by-step explanation:

Let's find the coordinates from the table values.

(2, 1), (3,4), (3, 3), (4, 2), (5, 5)

Here the input 3 has two outputs 4 and 3

3 is associated with two numbers 4 and 3.

Therefore, it is not a function.

Answer: a) No, because one x-value corresponds to two different y-values.

Hope you will understood the concept.

Thank you.

Answer:

Choice A is correct.

Step-by-step explanation:

We have ordered pair in the table:

(2,1) (3,4) (3,3) (4,2) (5,5)

We have to explain is it a function or not ?

Function is a rule that gives each input a single output.

It is not a function because one x value correspond to two different y values.

It is shown from the table that the input 3 has two different output values that is 4 and 3.

Input 3 has two outputs 4 and 3.

Choice A is correct.

Answer this question correctly and you'll get a good 13 points! Please help me! :) Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 4 h, and Car B traveled the distance in 4.5 h. Car B traveled 5 mph slower than Car A.How fast did Car B travel? How many MPH?

Answers

Time = Distance / Speed OR Distance = Time * Speed OR Speed = Time * Distance

Since both cars travelled the same distance; it is safe to have this formula to get the actual distance travelled.

Let X = distance in MPH

Car A                          =        Car B
4 hours * X                 =    4.5 hrs * (X - 5MPH)
4X                               =    4.5(X-5)
4X                                = 4.5X  - 22.50
4X - 4.5X                    =  -22.50
-0.5X                          = -22.50
X                                = -22.50 / -0.5
X                                = 45 MPH

Speed of Car B = 4.5 hrs * (45-5)
                           = 202.50 - 22.50
Speed of Car B =  180 MPH

TO CHECK
Speed of Car A  = 4hrs * 45 MPH
Speed of Car A  = 180 MPH
