Answer:
Answer; Mean = p = 0.75
Standard deviation =0.0274
Step-by-step explanation:
Mean = p = 0.75
Standard deviation = √ [ p ( 1 - p) / n ]
= √ [ 0.75 * ( 1 - 0.75) / 250]
= 0.0274
Answer: 3 hours
Step-by-step explanation:
If you add up 25+15=40 if you add up 40+15=55, 55+15=70, 70+15=85
Answer:
x = 18
Step-by-step explanation:
By the rule of Consecutive Interior Angles which define what these angles are, they both will add up to 180. As such we can put the sum of these two angles set equal to 180, and solve algebraically
(8x - 20) + (3x + 2) = 180
8x - 20 + 3x + 2 = 180
11x - 18 = 180
<u> + 18 +18</u>
11x = 198
x = 198/11
x = 18
