Show how to use a power of 10 to write 42.66 / 2.97 as an equivalent expression with a whole number divisor

PLEASE HELP DUE TONIGHT!!
WILL MARK BRAINLIEST!!

Answers

Expressing the given equation as a power of 10 with the divisor expressed as an whole number can be written as [tex] \frac{42.66 \times 10^{2}}{297}[/tex]

Given the expression :

42.66/2.97

Expressing the numbers as a power of 10 :

Dividend = 42.66 Divisor = 2.97

To convert the divisor to a whole number :

Multiply both by 100

Dividend = 42.66 × 100Divisor = 2.97 × 100 = 297

Expressing dividend as a power of 10 :

Dividend = 42.66 × 100 = 42.66 × 10²

Hence, the equivalent equation would be : [tex] \frac{42.66 \times 10^{2}}{297}[/tex]

3. A random sample of 100 people was taken. There were sixty people who favored Brand A. We are interested in determining whether or not the proportion of the population in favor of Brand A is significantly more than 55%. At a 0.05 level of significance, it can be concluded that the portion of the population in favor of Brand A is ____. a. Significantly greater than 60% b. Not significantly greater than 55% c. Not significantly greater than 60% d. Significantly greater than 55% e. None of the above

Answers

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:

[tex]\overline{p}[/tex] is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.

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.

Serina and 2 friends go out for dinner. Their bill is $92.18. How much more would
they pay if they left a tip of 20% instead of a tip of 15%?
$9.22
$4.61
$6.91
$2.76

Answers

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

What is the in minute taken to cover 8.1km at an average speed of 5m/s

Answers

9514 1404 393

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.

Answers

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

What is probability?

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
