Which of the following is NOT an observation about critical values? Choose the correct answer below. A. A critical value is the number on the borderline separating sample statistics that are likely to occur from those that are unlikely to occur. B. The number z Subscript alpha divided by 2zα/2 is a critical value that is a z score with the property that it separates an area of alpha divided by 2α/2 in the right tail of the standard normal distribution. C. The number z Subscript alpha divided by 2zα/2 is a critical value that corresponds to an area of 1minus−alpha divided by 2α/2 to its left. D. A critical value is the area in the right-tail region of the standard normal curve.

step-by-step explanation:

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
