Answer:
m<PQR = 80°
Step-by-step explanation:
<u>Points to remember</u>
Sum angles in a linear pair is 180
<u>To find the value of x</u>
It is given that, angle PQR and angle RQS are linear pairs, and
m< PQR =5x+5 and m<RQS =11x-65
m<PQR + m<RQS = 180
5x + 5 + 11x - 65 = 180
16x -60 = 180
16x = 180 + 60
16x = 240
x = 15
<u>To find the value of angle PQR</u>
m<PQR = 5x + 5
= 5*15 + 5
= 75 + 5 = 80
Therefore m<PQR = 80°

Answer: 
.
Step-by-step explanation:
Given : Sample size : n= 64 , the sample is a large sample (n>30), so we can apply z-test.
Sample mean = 
Standard deviation : 
Level of confidence:
Then, critical z-value =
The confidence interval to estimate the population mean is given by :_
Hence, the 95% confidence interval to estimate the population mean can be computed as .

Answer:
n(A) = 2701
Step-by-step explanation:
If we subtract 299 from the numbers in the set, we get the counting numbers ...
{1, 2, 3, ..., 2701}
The number of elements in the set is 2701:
n(A) = 2701
