Answer:
75.4 ft³
Step-by-step explanation:
Volume of a cone = πr²h/3
π = 3.14
radius, r = diameter / 2
= 6ft/2
= 3 ft
Height, h = 8 ft
Volume of a cone = πr²h/3
= (3.14 * (3)² * 8) / 3
= (3.14 * 9 * 8) / 3
= 226.08 / 3
= 75.36
Volume of a cone = 75.36 ft³
Approximately to the nearest tenth = 75.4 ft³
Answer:
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
Step-by-step explanation:
The following information is missing in the question:
Mean, μ = 170
Standard Deviation, σ = 30
Using the given information, we may solve the question as:
We are given that the distribution of distribution of cholesterol levels in teenage boys is a bell shaped distribution that is a normal distribution.
Formula:
a) P( cholesterol level greater than 225)
P(x > 225)
Calculation the value from standard normal z table, we have,
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
Answer:
396°
Step-by-step explanation:
Difference = 357 -(-39) = 357+38 = 396°
<span>N(100, 16) means a normally distributed population with a mean of 100 and a standard deviation of 16.
Using the 95% confidence level factor (1-tail), which is approximately 1.65, then, any IQ that exceeds:
100 + 16*1.65 is higher than 95% of the population. I'd consider that unusually high.</span>
Volume equals mass divided by density.
Hope this helps,
