A = person is female
B = person holds a managerial position
A) explain what P(A)= 0.47 means in context = of the population, 47% is composed of females.
<span>B) explain what P(B|A)= 0.34 means in context = 34% is the probability that the person chosen is a female manager
</span>
<span>C) what is the probability that a randomly chosen employed person is a male? 53%</span>
<span>D) what is the probability that a randomly chosen employed person is a female manager? 34% </span>
<span>E) what is the probability that a randomly chosen employed female is not a manager? 72%

Answer:
1/3
Step-by-step explanation:
Parallel lines have the same slope.
Put the line in slope-intercept form first,though.
3y=x+6
divide by 3
y=1/3x+2
Answer:
2% per year.
Step-by-step explanation:
Solving our equation
r = 960 / ( 12000 × 4 ) = 0.02
r = 0.02
converting r decimal to a percentage
R = 0.02 * 100 = 2%/year
The interest rate required to
accumulate simple interest of $ 960.00
from a principal of $ 12,000.00
over 4 years is 2% per year.
Answer: (3,4)
Step-by-step explanation:
To find the midpoint, you want to use the formula . Since we are given the two points, we can plug them in and solve.
[add numerator]
[divide]
Now, we know that the midpoint is (3,4).
Answer:
option D
Step-by-step explanation:
Clearly from the graph we say that at x = 4 and x = -6, f(x) = 0
Now we will check this with your options.
A) f(x) = (x + 1 )² - 5
at x = 4, f(x) = 25 - 5 = 20 ≠ 0 ; not A
B) f(x) = x - 5
at x = 4, f(x) = 4 - 5 = 1 ≠ 0 ; not B
C) f(x) = (x + 1 )³ - 5
at x = 4 , f(x) = 125 - 5 = 120 ≠ 0 ; not C
D) f(x) = | x + 1 | - 5
at x = 4 , f(x) = | 4 + 1 | - 5
= 5 - 5 = 0 ; satisfies
at x = -6 , f(x) = | - 6 + 1 | - 5
= | - 5 | - 5
= 5 - 5 = 0 ; D satisfies [ | - a | =a , absolute value function ]
