Same as the car one
A=Pe^(rt)
when it is a decay, make r negative
P=23781 and r=-0.032 and t=17
A=23781e^(-0.032*17)
A=23781e^(-0.554)
A=13803.01
so about 13803 people is the population after 17 years
Answer: choice A
---------------------------------------------------------------------
---------------------------------------------------------------------
Work Shown:
P(TV) = (number who watch tv)/(number total)
P(TV) = 30/100
P(TV) = 0.30
P(Girl) = (number of girls)/(number total)
P(Girl) = 55/100
P(Girl) = 0.55
P(TV)*P(Girl) = 0.30*0.55 = 0.165 which rounds to 0.17
We'll use this value later. So let's call this M = 0.17
Look in the "girl" row and "tv" column. The value 17 is here.
This is out of 100 people total, so
P(TV and Girl) = 17/100 = 0.17
Call this value N = 0.17
Because M = N = 0.17 approximately, this means that the two variables "TV" and "Girl" are approximately independent
So the equation P(TV and Girl) = P(TV)*P(Girl) is approximately true in this example.
This points to choice A being the answer.
Answer:
x = 12
Step-by-step explanation:
Solve for x:
(3 x)/4 = 9
Multiply both sides of (3 x)/4 = 9 by 4/3:
(4×3 x)/(3×4) = 4/3×9
4/3×3/4 = (4×3)/(3×4):
(4×3)/(3×4) x = 4/3×9
4/3×9 = (4×9)/3:
(4×3 x)/(3×4) = (4×9)/3
(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:
x = (4×9)/3
9/3 = (3×3)/3 = 3:
x = 4×3
4×3 = 12:
Answer: x = 12
3 i think , sorry if u get wrong
Answer:
$8 loss
Step-by-step explanation:
$10 profits, $7 profits, $25 loss
$10+$7=$17 profits
$25 loss - $17 profits = $8 loss
