Answer: 2790 students
Step-by-step explanation: With the given information, you could set up a ratio of 30/2 = x/186. When you cross multiply that, you get 2790.
13 x 13
or
13^2 (13²) will give you 169
and when two negative numbers are put together you get a positive so in this case -13 would work too.
Given:
square shape.
diagonal = 44 inches
The frame is square shape therefore its side lengths are equal. We need to solve for the side length using the diagonal.
a = √2 d/2
a = √2 44/2
a = √2 22
a = 1.414 * 22
a = 31.112 or 31 inches
Perimeter: 31 inches * 4 sides = 124 inches
Use the pythagorean theorem A² + B² = C²
A and B are legs and C is the hypotenuse
so- A² + 12² = 24² A² + 144 = 576
-144 -144
A² = 432 then you have to take the square root
of each side
so- A = √432 or aprox. 20.78
Answer: 95% certain that true proportion of population "p" is contained in (0.604, 0.781)
Step-by-step explanation:
We know that a 95% confidence interval is a range of values that you can be 95% sure that true mean of the population or true proportion of population lies in it .
Given : The 95% confidence interval for p was calculated to be (0.604, 0.781).
It means that we are 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
Hence, the correct interpretation for this interval :- 95% certain that true proportion of population "p" is contained in (0.604, 0.781).
