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: Look at the variables (letters) and plug them in
Step-by-step explanation: You plug in the variables into the problem, then you separate the other variable that you don't know from your whole number by bringing it to the other side. Then you can divide or whatever you have to do.
Answer:
A scientific calculator costs $3.50 today. I remember when they cost about $75. What is the percent decrease in the price of a scientific calculator?
In other words: The decrease in price is what percent of the original price?
% Decrease= (Decrease in price(New price-Old Price))/(Original Price(old price))×100

Answer:
(1,3) or (3,7)
Step-by-step explanation:
y=x²-2x+4.......... i
y=2x+1............... ii
Equating i and ii,
x²-2x+4=2x+1
x²-2x-2x+4-1=0
x²-4x+3=0
x²-x-3x+3=0
x(x-1)-3(x-1)=0
(x-1)(x-3)=0.
Either, x=1 or x=3.
If x=1,y=3 and if x=3, y=7
The points are (1,3) or (3,7)
