Answer:
The height of the ball is less than 17 feet for t > 2 seconds.
Step-by-step explanation:
The height of the ball after t seconds is given by the following equation:
For which interval of the time is the height of the ball less than 17 feet
This is t for which:
So
Multiplying by -1
The height of the ball is less than 17 feet for t > 2 seconds.
Answer:
The answer is below
Step-by-step explanation:
a) For a normal model the sample size has to be equal or greater than 30 so that it can be a normal distribution.
b) Given that:
μ = 11.2 minutes, σ = 4.8 minutes, n = 45
The z score determines how many standard deviations the raw score is above or below the mean. It is given by:
For x < 10 minutes
Therefore from the normal distribution table, P(x < 10) = P(z < -1.68) = 0.0465
The answer is 3:9 because it says that he sold 3 out of the 12 paintings and so it asks first of how many did he sell and he sold three and how many did he not sell and so it's nine left
The distance all the way around the sidewalk (the circumference) is 300 pi. 45 degrees is 1/8 of 360 degrees, so the two paths cut 1/8 of the circumference. That's 37.5 pi = 117.81 ft. The nearest whole foot is 118 ft.
