Answer:
The reasonable range for the population mean is (61%, 75%).
Step-by-step explanation:
The interval estimate of a population parameter is an interval of values that consist of the values within which the true value of the parameter lies with a certain probability.
The mean of the sampling distribution of sample proportion is, 
.
One of the best interval estimate of population proportion is the 95% confidence interval for proportion,
Given:
n = 150
= 0.68
The critical value of <em>z</em> for 95% confidence level is:
Compute the 95% confidence interval for proportion as follows:
Thus, the reasonable range for the population mean is (61%, 75%).
(100% - 7%) × 7,500
= 93% × 7,500
= 93 ÷ 100 × 7,500
= 93 × 7,500 ÷ 100
= 697,500 ÷ 100
= 6975

Answer:
Hence the corresponding equation of the given problem will be:
y'=|x-5|-1
Step-by-step explanation:
Let y' denote the corresponding equation after the translation of the given function y
We are given a equation of a function as: y=|x|.
Now we have to write an equation such that there is a translation 1 unit down and 5 units right of y=|x|.
We know that for any function f(x) the translation 'a' units down is given by:
f(x)-a
And the translation 'b' units right of a function g(x) is given by:
g(x-b)
Hence the corresponding equation of the given problem will be:
y'=|x-5|-1
The total surface area consists of the base area and the surface area (the area of all lateral faces). The base is a hexagon with side a=3 cm.
sq. cm.
Each lateral face is an isosceles triangle with height h=12 cm and base a=3 cm. The area of one such lateral triangle is
sq. cm.
Then the total surface area is:
sq. cm.
Answer: 119.7 sq. cm.
26/2 is 13 that is the answer 13 is the answer
