Answer:
z= 69
Step-by-step explanation:
79+122+90+z=360 angle sum property
360-291=69
so z=69 degree
We use the simple rules of statistics to accept the null hypothesis
68% of the data falls within 1 sd of the mean95% of the data falls within 2 sd of the mean 99% of the data falls within 3 sd of the mean
20 falls between the range of -56 to 56 (from the given 95% c.i.), hence we accept the null hypothesis; else, if the mean falls outside the range, we reject the null hypothesis.
Answer:
2 right and 5 down
Step-by-step explanation:
Answer:
a.2
Step-by-step explanation:
Perimeter of a square=4*side length
160=4*side length
40=side length
Therefore, 39.99999 (repeating 9s) is the maximum side length in feet for the perimeter to be less than 160. If it was 40 feet as the side length, then it would not be less than 160.
Hope this helps!
