A sample of 75 information systems managers had an average hourly income of $40.75 with a standard deviation of $7.00. The 95% c

Response:

12 --> 15

This reflects a 25% rise.

To calculate the increase: New Number - Original Number

15 - 12 = 3

Next, divide the increase by the original number and multiply the result by 100.

3/12 = 1/4 = 0.25 x 100 = 25

Thus, the percentage increase amounts to 25%

Answer:

AC and OA

Step-by-step explanation:

-A secant refers to a line that intersects two points on a circle.

-We have a square OABC with each side measuring 6cm and a circle with radius r=5cm, centered at O. The circle's radius is shorter than the side of the square:

-The circle intersectsOA andOC, while it does not intersect AB and BC.

Therefore, AC and OA serve as secants for the circle.

Start with 0. Subtracting three checks of $35 gives 0 - 35 - 35 - 35 = -105. Subtract the $15 overdraft penalty to get -120. So the balance is -$120. hope this helped.
