Answer:
The maximum height is 191.063 ft
Step-by-step explanation:
We can easily solve this question by plotting the graph of the equation below
h(t)=-16t^2+Vt+h
Where
h = initial height = 2ft
V = initial speed = 110 ft/s
t = time in seconds
Please, see attached image below
The maximum height corresponds to
191.063 ft
The answer is 24m^2 i just finished that test and that was the answer.<span />
Step-by-step explanation:
Will bought several books that cost $ 2.50 each and received a $ 2 discount on the total bill. If he paid $ 10.50, how many books did he buy ?
2.50x - 2.00 = 10.50
2.50x = 10.50 + 2.00
2.50x = 12.50
x = 12.50/2.50
x = 5....he bought 5 books
Answer:
C. 50
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

The higher the margin of error, the wider an interval is.
As the sample size increases, the margin of error decreases. If we want a widest possible interval, we should select the smallest possible confidence interval.
So the correct answer is:
C. 50
Answer :
The shape of the distribution of the sample usually contains the given two points :
1. The sampling distribution is skewed for small sample sizes. Also, the distribution will be non-normal if the sample size is small
2. The shape of the sampling distribution gets more and more normal-like (bell shaped) as the sample size increases
For sample size, n = 2
The sampling distribution will be skewed for this sample size
For sample size, n = 70
The shape of the sampling distribution for sample size of 70 will be more normal as compared to that of sample size of 2
