Answer:
w is 22.5°
See solution in the photo
1 foot = 12 inches
1/4 foot = 12/4 = 3 inches
61 +3 = 64 inches tall ( 5 ft 4 inches)
To make it easier say the number out loud. 26.2. Twenty six and two tenths. You could also say twenty six point two but the first way to say it makes it easier to write on paper though.
Twenty six and two tenths can also be reduced to twenty six and one fifth.
105 is the product of 15 and 7.
Answer:
Yes
Step-by-step explanation:
Given that your classmate suggests that the margin of error in the interval could be reduced if the confidence level were changed to 90% instead of 95%.
This is a true statement
Reason:
Confidence interval = mean±margin of error
margin of error = Critical value * Std error
Thus we have the higher the margin of error the wider the confidence interval.
And the higher the critical value the higher the margin of error.
In other words when confidence level is reduced from 95% to 90% we get reduced critical value and as a result narrower confidence interval.
True statement
