Answer:11 days
Step-by-step explanation:
y =2x+1
7 divided by 3= 2 remainder 3
Don't worry about the three use the 2 times 5 to get 10.
Then 10 plus 1 to get 11. If you don't believe me then do this: 3 times 2 to get 6 then plus 1 to get 7
The answer is most likely C. Cubic meters.
In the second one I'm pretty sure you just measure the length of the points.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
It is given that;
Margin of error E = 0.7
Confidence interval 98% = 1-0.98 = 0.02
Standard deviation = 6 hours
Number of MRI machines needed per day n, = [(z alpha/2 * SD)/E]²
Z alpha/2 = 1.645 at alpha = 0.1
Inputting these values into n we have that
[(1.645*6)/0.7]²
= 14.1²
= 198.81 is approximately equal to 199
