Answer: 0.6812
Step-by-step explanation:
Let p be the population proportion of trees are infested by a bark beetle.
As per given: p= 12%= 0.12
Sample size : n= 1000
Number of trees affected in sample = 1000
Sample proportion of trees are infested by a bark beetle. = 
Now, the z-test statistic : 
So, 
Hence, the value of the z-test statistic = 0.6812 .
Answer:
a.4
Step-by-step explanation:
because
F(x) =x² - 10x, f⁻¹(x) =?
1st find the missing square of x²-10x, ==> (x-5)² - 25
y= (x-5)² - 25; replace x by y and v0ce versa: x= (y-5)² -25
or
(y-5)² = x+25
y-5 = √(x+25) and y = √(x+25) -5
Domain = {x∈R: X>= 25} AND Range ={y∈R: y>= 5}
Answer:
The answer is 54 9/14
Step-by-step explanation:
what u do is this
#1. 765 divided by 14 which equals 54.64285714. Don't worry about the numbers after the decimal.
Then u do 65-54= 9 so u have 54 9/14
to check yourself just do 14 times 54= 756 + 9 = 765
