<h2>
The total number of items does he buy 5 (three pens and two notebooks).</h2>
Step-by-step explanation:
The total amount spend by Mr. Loretta = $4.83
The cost of each pen = $0.95 and
The cost of each notebook = $0.99 and
To find, total number of items he buy = ?
∴ The cost of one pen and one notebook = $0.95 + $0.99 = $1.94
The cost of two pens and two notebooks = $1.94 × 2 = $3.88
∴ The cost of three pens and two notebooks = $3.88 + $0.95 = $4.83
Thus, the total number of items does he buy 5 (three pens and two notebooks).
The length for the sides of the rug could be 4 feet, 4 feet, and 4 feet.
Answer:
The correct option is;
e. 2500
Step-by-step explanation:
The formula for sample size is given by the following formula;
At 95%, z = 1.96
ε = Margin of error = 0.02 = 2%
Finding the sample size, n, given only the margin of error is by the following formula;
Margin of error = 100/√n
Therefore, we have;
2 = 100/√n
√n = 100/2 = 50
n = 50² = 2500
Therefore, the correct option is e. 2500.
