Answer:
9413
Step-by-step explanation:
Given that :
Error = $2 ; Standard deviation (σ) =99 ; α = 95% = 0.95
Zα/2 = Z0. 05/2 = 1.96 (Z probability calculator)...
n = sample size
Recall:
n = ((Zα/2 * σ) / Error)^2
Using the formular above, the sample size n can be obtained ;
n = ((1.96 * 99) / 2)^2
n = 97.02^2
n = 9412.8804
n = 9413
Answer: 8x = 56
Step-by-step explanation:
Since the information given is that Francis plants an orchard of peach trees and that he plants 56 trees in 8 equal rows, the equation that represents this situation if x is the number of trees in each row will be:
(8 × x) = 56
8x = 56
Therefore, to know the number of trees in each row, we've to find the value of x. This will be:
8x = 56
x = 56/8
x = 7
Therefore, the number of trees in each row is 7.
Answer:
Step-by-step explanation:
Let
![x=1.323232...](https://tex.z-dn.net/?f=x%3D1.323232...)
Multiply x by a power of
, one that keeps the decimal part of the number the same:
Subtract
from
The repeating decimals should cancel out
solve for x
Divide by
both sides
Do 40divided by two then divide 5 by 2
