Answer:
x = 15
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
8x - 7 + x + 7 + 2x + 15 = 180 , that is
11x + 15 = 180 ( subtract 15 from both sides )
11x = 165 ( divide both sides by 11 )
x = 15
Answer:
95>=X <=100. More or equal to 95 or equal or less than 100.
Step-by-step explanation:
The Total of the first score is needed first
81+87+ 94+93=355
The total of this score
Let X be the 5TH score we are looking for
(355+ X)/5= 90
355+X= 450
X= 450-355
X= 95 the person needs to sore between 95 and 100 ( which is the highest possible score).
Answer: 56
Step-by-step explanation:
Answer:
0.0228
Step-by-step explanation:
Given that 
-Let X be the height of the randomly selected man.
-The probability that X>75 inches is calculated as:

Hence, the probability that a random pick is taller than 75 inches is 0.0228
The conversion of (240mL)/1 * (10^-3L)/1mL = .24L
