A researcher is interested in studying weight of adolescent females ages 10-13 to determine if weights in 2008 have significantly increased since 1988. She measures the weight of a randomly selected sample of women. Assume the weights are normally distributed.

100 103 93 90 91 101 85 89 79 87

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

x = 23.78
