Answer:
The results do not in anyway represent the population reason been that the sample does not represent professors from different areas but only tend to represent 50 professors from his hometown university
Step-by-step explanation:
Based on the information given the results of his survey does not in anyway represent the entire response from the population of college professors reason been the surveys carriedout by him was only for 50 professors from the university in his hometown and not professors from different areas which means that the sample or survey about the amount of money that average college professor make collected by him was not accurate.
Therefore for him to have accurate result he have to survey professors from different area which will inturn give him the accurate sample
The measure of <u>angle b</u> is 112° and the measure of <u>angle c</u> is 68°
<h3>Calculating the measures of angles </h3>
From the question, we are to determine the measures of the missing angles
From the diagram,
b = 112° (<em>Vertically opposite angles</em>)
∴ b = 112°
Also,
112° + c = 180° (<em>Sum of angles on a straight line</em>)
c = 180°- 122°
∴ c = 68°
Hence, the measure of <u>angle b</u> is 112° and the measure of <u>angle c</u> is 68°

For a geometric sequence, an = ar^(n - 1)
a2 = ar^(2 - 1) = ar = -12 . . . . . . . . (1)
a5 = ar^(5 - 1) = ar^4 = 768 . . . . . . (2)
(2)/(1) = ar^4/ar = 768/-12
r^3 = -64
r = ∛(-64) = -4
From (1), ar = -12
-4a = -12
a = -12/-4 = 3
Therefore, an = 3*(-4)^(n - 1)
Should be 61 cm but you can double check
Answer:
4
Step-by-step explanation:
a term is simply separated by either a + or a - which means the terms here is 4x,2x,3x and 5
