Answer:
<h2>B. 243</h2><h2 />
Step-by-step explanation:
F(x) = 3^x
then
F(5) = 3^5 = 3×3×3×3×3 =243
Answer:
The standard error of the mean = 2
Step-by-step explanation:
Given that:
The standard deviation σ = 14
The sample size n = 49
The sample mean
= 56
The formula for calculating the standard error can be expressed as:
![S.E = \dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=S.E%20%3D%20%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
![S.E = \dfrac{14}{\sqrt{49}}](https://tex.z-dn.net/?f=S.E%20%3D%20%5Cdfrac%7B14%7D%7B%5Csqrt%7B49%7D%7D)
![S.E = \dfrac{14}{7}](https://tex.z-dn.net/?f=S.E%20%3D%20%5Cdfrac%7B14%7D%7B7%7D)
S.E = 2
Therefore, the standard error of the mean = 2
The polyhedron has:
6 Faces, 8 vertices and 12 edges <u>in</u><u> </u><u>total</u><u>.</u>
But
3 Faces, 7 vertices and 7 edges <u>are</u><u> </u><u>visible</u><u>.</u>
29°
triangles can only have 180°
This is a right triangle, so one angle is 90°, leaving us with 90° left
90°-61°= 29°
As the input goes up by 3, the output goes down by 1.
