It would be 70=20x.

You would multiply 20 (snake’s speed) by x to get the cheetah’s maximum speed because the question says that the cheetah is 20 times faster than the snake

nordsb [41]

Given :

A 18-mile taxi ride takes 21 minutes and costs $12.60.

To Find :

The cost of a 39- mile taxi ride. What unit price do you need.

Solution :

Unit price per mile :

$p=\dfrac{12.60}{18}\\\\p = \$0.7\ /mile$

Cost of 39 mile taxi ride :

$C = 39\times p\\\\C=39\times 0.7\\\\C=\$27.3$

Therefore, unit price is $27.3 and unit price is $0.7 / mile .

Hence, this is the required solution.

Consider the following hypothesis test: H 0: 20 H a: < 20 A sample of 50 provided a sample mean of 19.4. The population stand

goblinko [34]

Answer: p-value is 0.016.

Step-by-step explanation:

Since we have given that

$H_0:\mu=20\\\\H_a:\mu$

Sample mean = 19.4

Sample size n = 50

Standard deviation = 2

We need to find the test statistic value which is given by

$z=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\\\z=\dfrac{19.4-20}{\dfrac{2}{\sqrt{50}}}\\\\\\z=\dfrac{-0.6}{0.28}\\\\z=-2.14$

p-value is given by

$P(Z>Z_{critical})\\\\=P(Z>-2.14)\\\\=0.016$

Hence, p-value is 0.016.
