Your answer should be 4,719,000
<h2>Answer: </h2>
<u>In a right triangle, Relation of base and hypotenuse is cosine</u>.
cos40° = 10/h
0.76604 = 10 × h
0.76604h = 10
h = 10/0.76604 = 13.05units.

Answer:
( $74.623, $83.777)
The 90% confidence interval is = ( $74.623, $83.777)
Critical value at 90% confidence = 1.645
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = $79.20
Standard deviation r = $10.41
Number of samples n = 14
Confidence interval = 90%
Using the z table;
The critical value that should be used in constructing the confidence interval.
z(α=0.05) = 1.645
Critical value at 90% confidence z = 1.645
Substituting the values we have;
$79.20+/-1.645($10.42/√14)
$79.20+/-1.645($2.782189528308)
$79.20+/-$4.576701774067
$79.20+/-$4.577
( $74.623, $83.777)
The 90% confidence interval is = ( $74.623, $83.777)
Answer:
The margin of error (E) 
Step-by-step explanation:
Given,
mean 
standard deviation 
sample size 
Critical value ![=\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}]](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bz_%5Calpha%7D%7B2%7D%5Cquad%20%5Cquad%5Cquad%5B%5Cbecause%5C%3B%5Calpha%3D1-%5Ctext%7Bconfidence%20interval%7D%5D)

The margin of error (E) 
Hence, The margin of error (E)
