99% = 2.58
how to find ?
Divide your confidence level by 2: . 95/2 = 0.475. Step 2: Look up the value you calculated in Step 1 in the z-table and find the corresponding z-value. The z-value that has an area of .
For this case we can raise a rule of three:
600 employees -------------> 100%
270 employees -------------> x
Where the variable "x" represents the percentage of employees who are satisfied with their salary. So, we have:
Thus, 45% of employees are satisfied with their salary.
Answer:
45%
ANSWER
EXPLANATION
The total number of employees is 600.
The number of employees who are happy with their pay is 270.
The percentage of employees who are happy with their pay is the number who are happy with their pay divided by total number of employees times 100%
This simplifies to
Answer:
900
Step-by-step explanation:
10 times as much means *10
so we have
90*10=900
Answer:
900
Step-by-step explanation:
10 x 90 = 900
OR
90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 = 900
Answer:
Only one solution.
Step-by-step explanation:
y = 3x +2
y -2x =4
y - 2x = 4
=> y = 2x +4
y = 3x + 2
y = 2x + 4
Since both equations are not the same, so the answer cannot be "infinitely many solutions".
They both intersect each other 1 point, so it cannot be "no solutions".
So the answer is "Only 1 solution".

5. A number
Answer:
Step-by-step explanation:
Recall that an elementary matrix of a matrix operation is obtained by applying the matrix operation to the identity matrix. In this case, by replacement, it means changing the whole row of a matrix and replacing it with a the same row multiplied by a number k.
In this case, the solution is
What is the determinant of an elementary row replacement matrix?
An elementary n xn row replacement matrix is the same as the n x n identity matrix with Exactly one of the 1's replaced with some number k.This means this is the triangular matrix and so its determinent is product of its diagonal entries. Thus, the determinant of an elementary row replacement matrix is a number. Especifically, the number k we used to replace the one

Answer:
14h+15
Step-by-step explanation:
(7h + 7) + (7h + 8)
First simplify
Eliminate redundant parentheses
(7h+7)
7h+7+7h+8
Add the numbers
7h+(7)+7h+(8) . 7+8=15
7h+15+7h
Combine like terms
(7h)+15+(7h) (7h)+(7h)=14h
14h+15
The answer would be 14h+15
