The formula to find The area of a triangle is base*height/2.
They have given the base which is 41.5ft and the height which is 36ft.
input that into the formula:
b*h/2
41.5*36/2
=1494/2
=747ft
So the Area = 747ft

Step-by-step explanation:
The median is the number in the middle. The range is the max. number subtracted from the min number.
Answer:
x=±√7
Step-by-step explanation:
Hi there!
We're given the quadratic equation 6x²-42=0 and we need to find the roots of the equation (the values of x that make the equation true).
So we need to isolate x onto one side.
We can start by adding 42 to both sides
6x²=42
divide both sides by 6
x²=7
Now, take the square root of both sides (remember that when we take the square root, we get both POSITIVE and NEGATIVE answers).
x=√7 and x=-√7 (can be rewritten as x=±√7)
Hope this helps! :)
Answer:
She still has 60%
Step-by-step explanation:
First you make the 25 a 100 which is basically multiply by 4 which you should do the same for 10
so 40/100 is how much she game away
She gave away 40%
She still has 60%
Answer:
Step-by-step explanation:
P(0 personality in common) = 39/375 = 0.104
P(1 personality in common) = 69/375 = 0.184
P(2 personality in common) = 110/375 = 0.2933
P(3 personality in common) = 122/375 = 0.325
3
P(4 personality in common) = 35/375 = 0.093
3
b) No the probability did not add up to 1 because they do not cover the entire sample space
c) Sample space is 0, 1, 2, 3, 4 personality preferences in common
