You’re going to use your TI-83 graphing calculator to compute the area between values of 7 and 9 for a distribution whose mean i

s 8 and whose standard deviation is 2. You would enter:
a) normalcdf (7,9,8,2)
b) normalpdf (7,9,8,2)
c) invNorm (8,7,9)
d) normalcdf (8,2,7,9)
e) normalpdf (8,2,7,9)

Answer: The answer is A

Step-by-step explanation: You use normalcdf to find the area under a curve. The lower bound (in this case 7) goes first followed by the upper bound, mean, and standard deviation.

In parallelogram RSWY, find m
Oksanka [162]

Answer:

110 and 70

Step-by-step explanation:

opposite sides of parallelograms are equal so you can set 2x+30 equal to 5x-90

when you do this:

2x+30=5x-90

-2x      -2x

30=3x-90

+90    +90

120=3x

/3     /3

40=x

now you can plug 40 in for 5x-90

example:

5(40)-90

200-90

110

m<r=110

<r and <s are supplementary because they are consecutive angles

supplementary is when two angles add up to 180

since <r is 110, do 180-110 and get 70

m<s = 70
