Answer:
[a] not sure but try
Step-by-step explanation:
Answer:
You can use proportions by settling the ratio from the sample equal to the ratio from the population.
Explanation:
For Example is 3 out of 50 phones in a sample are defective, then an estimated 60 out of 1000 phones in a population are defective. this can be found by solving the proportion 3/50=x/1000 where x is the estimated number of defective phones in the population.

Assuming that the growth the function will be of the form
f(n) = P*R^n
where
P = Initial population
R = Growth rate per period
n = number of periods
In this problem, the only period or interval I see are days. So we'll use n to represent the number of days since the start. The initial population is 1000, and the ratio would be 1600/1000 = 1.6. So the formula becomes
f(n) = 1000*1.6^n
So let's evaluate that function using n=4.
f(n) = 1000*1.6^n
f(4) = 1000*1.6^4
f(4) = 1000*6.5536
f(4) = 6553.6
Since we can't have a fractional mosquito, round to the nearest integer, giving 6554.</span>
Answer:
9.48 mm
Step-by-step explanation:
C=59.59 mm
59.59=2*3.14*r
r=9.48 mm
The answer is the third option, which is: Trapezoid.
The explanation for this asnwer is shown below:
1- A rectangular pyramid is a solid whose base is a rectangle and its faces are triangles.
2- When you slice or cut a solid with a plane, you obtain a shape which is known as "Cross section".
3- In this case, if these plane is perpendicular to the base but does not pass through the top vertex of the rectangular pyramid, the intersection of the plane with the pyramid, or the resulting shape will be a trapezoid.
