Answer:
Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student is 3625 female statistics student
Step-by-step explanation:
Here, we have

Where:
n = Required sample size
σ = Standard deviation = 18.3
E = Margin of error = 1/2 year
= Critical score from the confidence level = 1.645
Therefore,

Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student = 3625 female statistics student.
Answer:
40.5
Step-by-step explanation:

Therefore the answer to the problem = 40.5
Answer:
x = -7
Step-by-step explanation:
Use the distibutive property on both side:
Right side:
4 ( 1 - x )
( 4 x 1 ) + 4 x -X )
4 - 4x
Left side:
-3 ( x + 1 )
( -3 x X ) + ( -3 x 1 )
-3x -3
4 - 4x + 2x = -3x - 3
Combine like terms:
( 2x + ( -4x ) ) + 4 = -3x - 3
-2x + 4 = -3x - 3
Add 3 to each side:
-2x + 7 = -3x
add 2x to each side:
7 = -x
Divide each side by -1:
-7 = x
The equation would be “An= 8(4)^n”. Your answer would be equal to 8 times 4 to the 4th power, which is 2048
Step 1: LCM of 24 , 30 and 60 = 120
so 120 is the least no which is divisible by all 24 , 30 and 60
Step 2: factors of 120 will be 2^3 * 3 * 5
so the least perfect square, which is divisible by 24, 30 and 60 will be
(2^3 * 3 * 5) x ( 2 * 3 * 5 ) = 3600
3600
