Answer:
.79 mm^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 (1) ^2
A = 3.14
Now we have 1/4 of the circle
The area is 1/4 of the full area
1/4 *3.14
.785
Rounding to the nearest hundredth
.79 mm^2
Answer:
let
tp=total points lost
l= points lost
q= question
tp=24
l= 3
if l= 3 and tp= 24 den q= tp÷l
24÷3=8
<h2>
Answer with explanation:</h2>
Let
be the population mean.
For the given claim , we have
Null hypothesis : 
Alternative hypothesis : 
Since alternative hypothesis is two-tailed , so the test is a two-tailed test.
Given : Sample size : n=220 ;
Sample mean:
;
Standard deviation: 
Test statistic for population mean:


By using the standard normal distribution table of z , we have
P-value ( two tailed test ) : 

Since , the P-value is greater than the significance level of
, it means we do not have sufficient evidence to reject the null hypothesis.
