Answer:
mean= 73.167
mode= 85
range= 47
median= 78.5
Step-by-step explanation:
46 58 72 85 85 93
mean= 73.167
mode= 85
range= 47
median= 78.5
x^2 = 16/100
We must solve for x by taking the square root of both sides.
But imagine x^2 = 9. x = 3 is a solution because 3^2 = 9. But x = -3 is also a solution because (-3)^2 = 9. So we need to add the plus and minus sign to account for all of our solutions.
√x^2 = √(16/100)
We square root both sides to remove the exponent 2 on x. Then
x = ±√(16/100)
Then we have to use a Property of Radicals which is √(x/y) = √(x) / √(y).
Then the square root of 16 is 4 and the square root of 100 is 10. 4/10 is 2/5 simplified.
Answer:
Step-by-step explanation:
P(heads) = 1/2
P(blue) = 1/4
P (heads and blue) = 1/2 * 1/4 = 1/8
When

you would have to use comon multiples to find what both numbers have in common, a short way of finding this would be

where (a) is the answer of the equation, (a) would be 2 because 8*2=16 meaning
