Students who attend Anytown College pay either in-state Calculate the standard deviation of the sum or out-of-state tuition, depending on where they reside. S=1+0.
The amount, I spent on in-state tuition for a randomly
selected student has a mean of $2,523.75 and a standard Os = $227.69
deviation of $1,003.25. The amount, O, spent on out-of-
state tuition for a randomly selected student has a mean
Os = $1,301.25
of $3,825.00 and a standard deviation of $1,126,50.
✓ Os = $1,508.48
Suppose we randomly select one student who pays in-
state tuition and one student who pays out-of-state tuition. os = $6,348.75
We can consider I and to be independent random
variables.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

whaere is the picture

step-by-step explanation:

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.
