Answer:

\left \{ {{h=15s} \atop {t=7s+200}} \right.

Step-by-step explanation:

Let h be equal to the number of meters the hare travels.

Let t be equal to the number of meters the tortoise travels.

Let s be equal to the number of seconds that pass.

The hare travels at a speed of 15 meters per second, which means 15s represents the number of meters the hare travels depending on the number of seconds that pass.

h=15s

The tortoise travels at a speed of 7 meters per second, which means 7s represents the number of meters the tortoise travels depending on the number of seconds that pass.

t=7s

However, because the tortoise got a 200-meter head start, we need to add 200 meters to our equation.

t=7s+200

Here is our system of equations:

\left \{ {{h=15s} \atop {t=7s+200}} \right.

I hope this helps!

area formula is

A=\frac{1}{2}(b1+b2)h

where:

b1 = small base

b2 = large base

h = height

then solve:

A=\frac{1}{2}(2+6)3=\frac{1}{2}(8)3=\frac{24}{2}=12

Data is collected to perform the following the hypothesis test:
nekit [7.7K]

Answer:

option f is right

Step-by-step explanation:

Given that data is collected to perform the following hypothesis test.

H_0: \mu = 5.5\\H_a: \mu >5.5

(right tailed test)

Sample mean = 5.4

p value = 0.1034

when p value = 0.1034 we normally accept null hypothesis.  i.e chances of null hypothesis true is  the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct

f) If the mean µ does not differ significantly from 5.5 (that is, if the null hypothesis is true), then the probability of obtaining a sample mean y as far or farther from 5.5 than 5.4 is .1034.
