tom drives 200 miles in 4 hour. he drives the first 32 miles at an average speed of 64mph. work out his average sped for the res
WINSTONCH [101]

Answer:

His average speed for the rest of the journey was of 48mph.

Step-by-step explanation:

We use the following relation to solve this question:

v = \frac{d}{t}

In which v is the velocity, d is the distance and t is the time.

First 32 miles at an average speed of 64mph.

So the time for these 32 miles is:

64 = \frac{32}{t}

64t = 32

t = \frac{32}{64}

t = 0.5

Rest of the trip:

200 - 32 = 168 miles in 4 - 0.5 = 3.5 hours. So the average speed is of:

v = \frac{d}{t} = \frac{168}{3.5} = 48

His average speed for the rest of the journey was of 48mph.

Question 4
sleet_krkn [62]

Answer:

\displaystyle about\:8\:units

Step-by-step explanation:

Use the Distance Formula:

\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = D \\ \\ \sqrt{[6 - 1]^2 + [-7 + 1]^2} = \sqrt{5^2 + [-6]^2} = \sqrt{25 + 36} = \sqrt{61} ≈ 7,810249676 ≈ 8

Since we are talking about distance, we ONLY want the NON-NEGATIVE root.

I am joyous to assist you anytime.

AVprozaik [17]

Answer: 17.89

Step-by-step explanation:

In binomial distribution, the standard deviation is given by :-

\sigma=\sqrt{np(1-p)}

As per given , we have

The number of vouchers in the sample with errors is denoted by x.

p= 0.20  , n = 2000

Then , \sigma=\sqrt{2000\times(0.2)(1-0.2)}

\sigma=\sqrt{320}=17.88854382\approx17.89

Hence, the standard deviation of x is 17.89.
