Answer:
it is B. 5
Step-by-step explanation:
9/-3= -3
-3 x -1 = 3
3+5 + 8
8+-3 = 5
Answer:
3/10
Step-by-step explanation:
Total number of employees = 7 + 9 = 16
Probability of a man being chosen first to be promoted = 9/16
Probability of the second choice is still a man for promotion = 8/15
Why 8/15?
The number of men left who are eligible for promotion after the 1st man was chosen for promotion is 9 - 1 = 8
The total number of people left after the 1st person is chosen for promotion that are eligible for promotion is 16 - 1 = 15
Hence Probability of choosing 2 men for promotion = 9/16 x 8/15 = 3/10
Answer:
When we have a mean M and a standard deviation S, the values that are within the mean absolute deviation are all the values in the interval:
[M -S, M + S]
In this case, we have:
M = 782
S = 52
Then the interval is:
[782 - 52, 782 + 52]
[730, 834]
Then any number between 730 and 834 are possible answers to this question, for example, we can choose:
789 and 801
6(G+9)
you have to use the distributive property.
6*G=6G
6*9=54
answer is 6G+54
Answer:
10x + 12 and 6x² + 11x - 7
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is length and w is width )
= 2(2x - 1) + 2(3x + 7) ← distribute parenthesis
= 4x - 2 + 6x + 14 ← collect like terms
= 10x + 12
--------------------------------------------------
The area (A) of a rectangle is calculated as
A = lw
= (2x - 1)(3x + 7) ← expand using FOIL
= 6x² + 14x - 3x - 7 ← collect like terms
= 6x² + 11x - 7
