Answer:
Step-by-step explanation:
A driver spent 45minutes to cover a distance of 120km
Convert minutes to hour
- 45 min = 45 /60 hr = 3/4 hr
Use the distance equation
Find the speed
Substitute the distance and time value and find the value of speed
- s = 120 / (3/4) = 120 * 4/3 = 160 km /h
1 yard = 3 feet
The foundation is 2/3 yard wide, by 1 yard deep by 10 yards long.
Volume is Length x width x height.
Volume = 2/3 x 1 x 10 = 6.66 cubic yards.
The answer is B.
Answer:
16%
Step-by-step explanation:
First, calculate the z-score.
z = (x − μ) / σ
where x is the value,
μ is the mean,
and σ is the standard deviation.
z = (12.5 − 11) / 1.5
z = 1
What this means is that 12.5 is 1 standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and +1 standard deviations. That means 32% is outside of that range. Since normal distributions are symmetrical, we can say that 16% is less than -1 standard deviations, and 16% is greater than +1 standard deviations.
Therefore, the probability that a man's shoe is greater than or equal to 12.5 (greater than +1 standard deviations) is 16%.
