Step-by-step explanation:
1. Let's calculate the unit price for each brand of diapers.
A. Stay-Dry: 108 diapers for US$ 25.18
Unit price = 25.18/108
<u>Unit price = US$ 0.23</u>
B. Uber-Soft: 180 diapers for US$ 39.14
Unit price = 39.14/180
<u>Unit price = US$ 0.22</u>
C. Cuddlies: 160 diapers for US$ 38.77
Unit price = 38.77/160
<u>Unit price = US$ 0.24</u>
<u>D. James should advise his mom to purchase Uber-Soft diapers, because the unit price is the lowest.</u>

Answer:
We can conclude that new fertilizer appears to be more effective on apple trees.
Step-by-step explanation:
Mean and standard deviation parameters are missing in the question, I will assume amounts as below:
At Frucht Orchards, apple trees produce an average of 840 pounds of fruit per tree with a standard deviation of 120 pounds. Their mango trees produce an average of 350 pounds of fruit per tree with a standard deviation of 190 pounds. Frucht Orchards is trying two new fertilizers. An apple tree fed Amazing Apples Fertilizer yielded 940 pounds of fruit, while a mango tree fed Amazing Mangos Fertilizer yielded 400 pounds of fruit. Which new fertilizer appears to be more “amazing”?
We need to calculate standardized values (z-scores) of fertilized apple and mango trees to decide which fertilizer appears to be more "amazing".
z score for an unique value can be calculated using the equation:
z= where
- X is the weight of the specific fruit that the fertilized trees produce.
- M is the average weight of the specific fruits that the trees produce.
- s is the standard deviation of the weights of specific fruit (583)
<u>For fertilized apple</u>
z=≈0.83
<u>For fertilized mango</u>
z=≈0.26
Since 0.83>0.26 we can conclude that new fertilizer appears to be more effective on apple trees.
Answer:
Step-by-step explanation:
Hi,
let's note the two integers a and b
We are asked to find b
<em>replace a in the first equation</em>
As b must be a positive integer, the solution is 11
Hope this helps
