Answer:
If you are looking for x it equals 80 degrees
Step-by-step explanation:
vertical angles are congruent
It’s 2 because you plug in “x+1” as y into the the first equation then solve for x.
Division by zero is undefined. That is a impossible question
Okay...
t-8<25
t<25 add 8 to 25
t<33
The correct answer is CI = (71.415%, 78.915%)
The correct option is (A)
<h3 /><h3>What is Confidence level?</h3>
A confidence interval is the mean of your estimate plus and minus the variation in that estimate.
Given:
x = 376
Sample = 500 students
CI= [(376/500-1.96 √((376/500)*(124/500)/500) , (376/500-1.96
√((376/500)*(124/500)/500)]
CI = (71.415%, 78.915%)
Hence, CI = (71.415%, 78.915%)
