Answer:
Rachel's score is 2.3333 standard deviations above the mean
Step-by-step explanation:
GRE scores are normally distributed
Let be G the random variable ''Gre scores''
G ~ N (mean,standard deviation)
G ~ N (600,30)
Rachel scored 670 on the analytic portion of the GRE.
670 - 600 will be the score above the mean
670 - 600 = 70
To find this in terms of standard deviation we divide by the standard deviation
70/standard deviation = 70/30 = 7/3 = 2.33333333 standard deviations
Well you would start by drawing a rectangle. Label one side W and One side (W+4) then you would set up this equation
2(W+4)+2W=28
2W+8+2W=28
4W+8=28
4W=20
W=5
So that's the width then you will plug it into (W+4)
(5+4)=9
So you have a room that has a length of 9 and a width of 4
Let me help you!!! ok, so remember, it is always easier when you are multiplying one fraction, and one decimal, to keep it simple, and make it either both decimals, or both fractions! so, for instance, i will change the 3/4 into a decimal:
*0.75
you get that by dividing the 3 by 4.
Now, you just divide the 0.75 x 29.2, which is (21.9) hope that helps!!!
