University officials say that at least 70% of the voting student population supports a fee increase. If the 95% confidence inter

val estimating the proportion of students supporting the fee increase is [0.75, 0.85], what conclusion can be drawn?
A. 70% is not in the interval, so another sample is needed.
B.70% is not in the interval, so assume it will not be supported.
C.The interval estimate is above 70%, so infer that it will be supported.
D.Since this was not based on population, we cannot make a conclusion.

Answer:

The interval estimate is above 70%, so infer that it will be supported.

Step-by-step explanation:

The evidence that 95% confidence interval estimating the proportion of students supporting the fee increase is [0.75, 0.85] supports university officials' claim that at least 70% of the voting student population supports a fee increase.

Therefore we can infer that a fee increase will be supported.

2 angles measure 40 degrees each, what does the third angle measure? what type of triangle is it?
zimovet [89]

Answer:

Part a): 100 degrees

Part b): Isosceles Triangle

Step-by-step explanation:

Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.

180 - 80 = 100

Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.

What is the value of this expression when c=-4 and d = 10?<br> 1/4(c3+d2)
Mumz [18]
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

What is the value of this expression when c = -4 and d = 10 ? \frac{1}{4} (c³ + d²)

<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>

<h3>Given:-</h3>

\frac{1}{4} (c³ + d²) where c = -4 and d = 10

<h3>To Find:-</h3>

The value of the expression \frac{1}{4} (c³ + d²)

<h2>Solution:-</h2>

\frac{1}{4} (c³ + d²) [Given expression]

Now, putting the value of c = -4 and d = 10 , we get,

\frac{1}{4} { (-4)³ + (10)² }

\frac{1}{4} ( -64 + 100 )

\frac{1}{4} ( 36 )

\frac{1}{4} × 36
