The answer is C. First, the area of the plot should be the multiplication of the two side lengths, so 11.7 * 15.4=180.18. However, we have to look at the significant digits to decide to what digit should we round the answer to. Since both 11.7 and 15.4 are accurate to the tenths digit, 180.18 should also be so, so we should round it to 180.2.

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:
C
Step-by-step explanation:
Given y ∝ then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = - 2 when x = 14 , then
- 2 = ( multiply both sides by 14 )
- 28 = k
y = - ← equation of variation
N could be equal to 9,10,11, etc
