Eating from the inside cover of the first book to the back cover of the last boook, will take the bookworm 25 full books (that is from B to Z) and for book A, the total distance should be subtracted by 1/4 (that is the length of the inside cover)
total distance covered = (2)(25) + (2 - 1/4)
The answer to the equation above is,
total distance covered = 51.75 inches
I THINK YOU FORGOT TO POST THE COMPLETE Q.
Answer:
9.8 x 2.2 = 21.56 m
distance = time x speed
speed = distance ÷ time
Step-by-step explanation:
The highest point he reached occurred at the vertex, which is at t = -b/2a = 2.2 second. Plugging in t = 2.2
9.8 x 2.2 = 21.56ft
Higher cliffs don't accelerate your fall -- acceleration is constant during free fall. The pull of gravity decreases infinitesimally at higher elevations, but it pulls you with an equal force from the first second of your jump until you decelerate when you hit the water.
Answer:
![\mu_{p}=p=0.81](https://tex.z-dn.net/?f=%5Cmu_%7Bp%7D%3Dp%3D0.81)
Step-by-step explanation:
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The population proportion have the following distribution
![p \sim N(p,\sqrt{\frac{p(1-p)}{n}})](https://tex.z-dn.net/?f=p%20%5Csim%20N%28p%2C%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D%29)
So under the null hypothesis the mean for the population proportion is p
![\mu_{p}=p=0.81](https://tex.z-dn.net/?f=%5Cmu_%7Bp%7D%3Dp%3D0.81)
And the standard deviationis given by:
![\sigma_{p}=\sqrt{\frac{p_0(1-p_o)}{n}}=\sqrt{\frac{0.81(1-0.81)}{1000}}=0.0124](https://tex.z-dn.net/?f=%5Csigma_%7Bp%7D%3D%5Csqrt%7B%5Cfrac%7Bp_0%281-p_o%29%7D%7Bn%7D%7D%3D%5Csqrt%7B%5Cfrac%7B0.81%281-0.81%29%7D%7B1000%7D%7D%3D0.0124)
