Step-by-step explanation:
Answer:
32 extra goodie bags mark brainlist pls
Step-by-step explanation:
You do 120x4=480
then do 25x3=75
then add 480+75=555
then do 635.00- 555= 80
then do 80 divided by 2.50= 32
Answer: x=-6
Steps
distribute
2-3(x+4)=8
2-3x-12=8
Subtract the numbers
2-3x-12=8
-10-3x=8
Rearrange terms
-10-3x=8
-3x-10=8
Add ten to both sides
-3x-10=8
-3x-10+10=8+10
Simplify
(add the numbers)
-3x=18
Divide both sides by the same factor
-3x=10
(Write this part in a fraction)
-3x/-3 = 18/-3
Last step simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
X=18/-3 (18 over -3 write it as a fraction)
So that leaves your answer to
X=-6
Let r represent reptiles
210=3r-120
330=3r
110=r
110 reptiles
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.
