Answer:
89
Step-by-step explanation:
1. She spent a total of 23 + 30 + 16 = 69 dollars.
2. That means she had at least 69 dollars to spend. But if it were 69 dollars, that would mean she had 0 remaining dollars because she spent it all.
3. But she had 20 dollars left after she spent the 69 dollars.
4. So that means she had 89 dollars before making the purchase
Y=2x^(1/2)
A=2⌠x^(1/2) dx
A=2[ (2/3)x^(3/2) ]
A=(4/3)[ x^(3/2) ] x=[1,4]
A=(4/3)(8-1)
A=(4/3)7
A=28/3 u^2
A=9 1/3 u^2
The answer to this question is
P= 12
Answer: Stratified random sampling
Step-by-step explanation:
- A sampling technique that involves the split of a population into smaller groups known as strata on the basis of some categories and then selecting individuals from each strata is known as Stratified random sampling.
Here, group of mean and women are two strata, and selecting individuals from each of them .
That means, this sampling method is "Stratified random sampling".
I believe the answer is 30
Requirement for completion:
85% x 142 employees
85/100 x 142 employees
= 120.7 . . . . make it 121 because there is no such thing as 0.7 person.
So, the amount of employees left to train at the end of the week should be:
121 - 91 = 30
