Given:
Side length of square = 2 in
To find:
The area of the square
Solution:
Area of the square:
Area = side × side
= 2 in × 2 in
Area = 4 in²
Therefore, the area of the square is 4 inches².
Answer:
37
Step-by-step explanation:
Given :
Sample size, n = 128
Mean, μ = 18
Standard deviation, σ = 5.4
Number of people who lost atleast 15 pounds :
The Zscore = (x - μ) / (σ)
Zscore = (15 - 18) / 5.4
Zscore = - 3 / 5.4
Zscore = - 0.5555
P(Z < - 0.555) = 0.28945
Number of people who lost atleast 15 pounds :
0.28945 * 128 = 37.0496
= 37 people

Answer:
Earnings = $1960
Step-by-step explanation:
The question is incomplete; however the missing part of the question asks his total earnings if he worked for 48 hours in a week
First, we need to determine the extra hour worked
Regular Hour = 40
Extra Hour = 48 - 40
Extra Hour = 8
Total Earnings is then calculated as follows:
Earnings = Regular Hours * Regular Charges + Extra Hours * Extra Charges
Earnings = 40 * 35 + 8 * Extra Charges
Since extra charges is twice regular charges, we have:
Earnings = 40 * 35 + 8 * 35 * 2
Earnings = 1400 + 560
Earnings = $1960
