A2+b2=c2
c2=10
x2+x2=100
2x=100
x=50
Divide by 2 to get 25.
Get square root of 25
Your answer is 5
Answer:
Step-by-step explanation:
It would be more obvious if it says z is a standard Normal variable and that the question is related to statistics.
From "Computing Probabilities Using the Cumulative Table" , the probability of z is less than 1.16, P(z<1.16) = 0.8770.
First find the area of the Room 30 x 30 = 900
We know each triangle can take up 112.5 sq ft
divide these numbers to find how many will be needed.
Then you can add the 112.5 four times to find how much it will cover. Subtract the 900 with that number and that will be what is left.
The Answer is -4x^2+10x+4
-4x^2 is not effected, as it has no like terms.
3x-(-7x) is equivalent to 3x+7x which equals 10x.
-5-(-9) is equivalent to -5+9 which equals 4.
