Use Pythagoras theorem
Hypotenuse²=Base²+ Height ²
H²=(8)²+(6)²
H²=64+36
H²= 910
H²=10√91 cm Solution
You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.
Distribute
10+4x+4+5
Combine like terms
19+4x
Final answer: 4x+19
Answer:
A.
Step-by-step explanation:
r=diameter/2
radius=52/2 (Q)
Q =26
Ok so divide 39 by 4 which is 9.75 then mulitiply that by 3 to get your answer of $29.25
