Answer:
Step-by-step explanation:
When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True or false?
This statement is false, or better still, ambiguous. 100 samples of size 30 (or greater) each, means 300 total and it can't be just 95 of them that will contain the true population mean.

Hello :
<span>Hello : let
A(-3,-3) B(5,4)
the slope is : (YB - YA)/(XB -XA)
(4+3)/(5+3) =7/8
an equation is : y=ax+b a is a slope</span>
y = (7/8)x +b
the line through
point (5,4) : 4 = (7/8)(5)+b<span>
<span>b = - 3/8
the equation is : y =(7/8)x- 3/8</span></span>
Answer:
Step-by-step explanation:
To find the inverse function for y = f(x), solve the equation ...
x = f(y)
x = 2y +1 . . . . . . . use the function definition
x-1 = 2y . . . . . . . . undo the addition of 1 (subtract 1)
(x -1)/2 = y . . . . . undo the multiplication by 2 (divide by 2)
The inverse function is ...
f⁻¹(x) = (x -1)/2
9x+18=90
9x=72
x=8
This is the answer for problem 10 above
Problem 11:
62+58= 120
180-120 =60
Therefore angle FEA is 60 degrees
59+ 61=120
180-120= 60
Therefore angle CHF is also 60 degrees
Rays:
EB and HD ; EA and HC are both parallel because they have equivalent degree angles
