Answer:
10.5
Step-by-step explanation:
Given
A = (1/4, 3)
B = (1/2, 4.5)
To get the coordinate of C as 7/4, what was done was to first take the difference in the x coordinates and then dilate the result by 7
To get the y coordinate;
- Take the difference in the coordinate
Difference = 3 - 4.5
Difference = -1.5
- Dilate the result by factor of 7
This is done y multiplying the result by 7;
y coordinate = 1.5 * 7
y coordinate = 10.5
Hence its y-coordinate is 10.5
Answer:
I think the answer would be the 4th one because it can make a triangle

Answer: c. 39.14 to 42.36
Step-by-step explanation:
We want to determine a 95% confidence interval for the average hourly wage (in $) of all information system managers
Number of sample, n = 75
Mean, u = $40.75
Standard deviation, s = $7.00
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
40.75 +/- 1.96 × 7/√75
= 40.75 ± 1.96 × 0.82
= 40.75 + 1.6072
The lower end of the confidence interval is 40.75 - 1.6072 =39.14
The upper end of the confidence interval is 40.75 + 1.6072 =42.36
B because 5xanything ends in 0 or 5
