Answer:

  27 minutes

Step-by-step explanation:

The relevant relations are ...

  1 min = 60 s

  1 km = 1000 m

  time = distance/speed

__

  time = (8.1 km)×(1000 m)/(1 km)/(5 m/s)×(1 min/(60 s))

  = (8.1×1000)/(5×60) min = 27 min

It takes 27 minutes to cover 8.1 km at a speed of 5 m/s.

Answer:

$4.61

Step-by-step explanation:

To calculate a tip of 20%, you would perform the following:

$92.18 * 0.20 = $18.436

Similarly, for a tip of 15%:

$92.18 * 0.15 = $13.827

The difference would just be subtracting the two tip amounts from each other!

$18.436 - $13.827 = $4.609

Then you round to the nearest cent.

$4.609 ≈ $4.61

Answer:

[tex]a=\displaystyle \frac{k}{w+v}[/tex]

Step-by-step explanation:

Hi there!

[tex]\displaystyle \frac{k}{a} =w+v[/tex]

Multiply both sides by a:

[tex]a*\displaystyle \frac{k}{a} =a(w+v)\\\\k=a(w+v)[/tex]

Divide both sides by (w+v):

[tex]\displaystyle \frac{k}{(w+v)} =\displaystyle \frac{a(w+v)}{(w+v)}\\\\\displaystyle \frac{k}{w+v} =a[/tex]

Testing the hypothesis, it is found that the correct option is:

b. Not significantly greater than 55%.

At the null hypothesis, we test if the proportion is not significantly more than 55%, that is:

[tex]H_0: p \leq 0.55[/tex]

At the alternative hypothesis, we test if the proportion is significantly more than 55%, that is:

[tex]H_1: p < 0.55[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

For this problem, the parameters are:

[tex]p = 0.55, n = 100, \overline{p} = \frac{60}{100} = 0.6[/tex]

Hence, the value of the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.6 - 0.55}{\sqrt{\frac{0.55(0.45)}{100}}}[/tex]

[tex]z = 1.01[/tex]

The p-value of the test is the probability of finding a sample proportion above 0.6, which is 1 subtracted by the p-value of z = 1.01.

Looking at the z-table, z = 1.01 has a p-value of 0.8438.

1 - 0.8438 = 0.1562.

The p-value of the test is 0.1562 > 0.05, which means that the proportion is not significantly greater than 55%, and option b is correct.

Answer:

If you WANT to divide pi, there is half a pi left.

Step-by-step explanation:

There are 2pi radians in a circle. So one quarter of the circle corresponds to half of pi (If you want to divide to get half of pi) . So it would then be: one quarter corresponds to a half.

The probability that when a coin is tossed, the result is tails = 1/2

The probability that when a single six-sided die is rolled, the outcome is 1 = 1/6

The probability that when a six-sided die is rolled, the outcome is 13 = 0

Probability is simply how likely something is to happen.

A).

The probability that when a single six-sided die is rolled, the outcome is 1.

When a dice is thrown, sample space = {1, 2, 3, 4, 5, 6}

All six digits are equally likely to occur.

P (occurring 1) = 1/6

B).

The probability that when a six-sided die is rolled, the outcome is 13.

When a dice is thrown, sample space = {1, 2, 3, 4, 5, 6}

13 does not occur in the sample space.

P (occurring 13) = 0

C).

The probability that when a coin is tossed, the result is tails.

When a coin is thrown, sample space = {H, T}

Both head and tail are equally likely to occur.

P (tail) = 1/2
