An Exercise Scientist believes that in recent time the the mean amount of time spent exercising has changed from 30 minutes a day. To test this claim a sample of 36 individuals is taken and a sample average of 35 minutes is calculated with a sample standard deviation of 14 minutes. What should the Scientist conclude at the 1% level of significance?

the answer is 5/14.

hope this .

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
