Answer: 12.10
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
The formula to calculate the z-score :-
For x= 5 degrees
For x= 10 degrees
The P-value : 
In percent , 
Hence, the percentage of days had a low temperature between 5 degrees and 10 degrees = 12.10%
Option 3: a 90 degree rotation clockwise
You can tell that it is 90 degrees because the original started completely in quadrant 2 and the final image is completely in quadrant 1. If it was only rotated 45 degrees the final image would be part in quadrant 2 and part in quadrant 1. It was rotated clockwise because that is the way a clock goes.
Hope this helps! ;)
Answer:
It would be 5 degrees hope this helped
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
Answer:
Step-by-step explanation:
<u><em>b).</em></u>
2x² - 9x - 5 = ( x - 5 )( 2x + 1 )
3x² - 15x = 3x ( x - 5 )
