show me 1/3 on a number line​

Answer:

A sample size of 551 is required.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Population standard deviation of 7 hours.

This means that [tex]\sigma = 7[/tex]

Determine the sample size required to have a margin of error of 0.585 hours.

This is n for which M = 0.585. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.585 = 1.96\frac{7}{\sqrt{n}}[/tex]

[tex]0.585\sqrt{n} = 1.96*7[/tex]

[tex]\sqrt{n} = \frac{1.96*7}{0.585}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*7}{0.585})^2[/tex]

[tex]n = 550.04[/tex]

Rounding up(as for a sample of 550 the margir of error will be a bit above the desired target):

A sample size of 551 is required.

Answer:

[tex]Change = \$8[/tex]

Step-by-step explanation:

Given

[tex]Bills = $20\ bills[/tex] (4)

[tex]Shirt = \$42[/tex]

[tex]Sweater= \$30[/tex]

Required

The change

First, we determine the amount paid,

To do this, multiply the number of bills by the worth of each bill.

So, we have:

[tex]Amount = 4 * \$20[/tex]

[tex]Amount = \$80[/tex]

Next, calculate the worth if item bought

[tex]Items = \$42 + \$30[/tex]

[tex]Items = \$72[/tex]

Subtract the items from the amount to get the change.

[tex]Change = \$80 - \$72[/tex]

[tex]Change = \$8[/tex]

Which of the following statements about Hannah’s claim is supported by the interval?

A) Hannah is likely to be incorrect because the difference in the sample means was 18.6−14.4=4.218.6−14.4=4.2 hours.

B) Hannah is likely to be incorrect because 9 is not contained in the interval.

 C)The probability that Hannah is correct is 0.99 because 9 is not contained in the interval.

 D)The probability that Hannah is correct is 0.01 because 9 is not contained in the interval.

 E)Hannah is likely to be correct because the difference in the sample means (18.6−14.4=4.2)(18.6−14.4=4.2) is contained in the interval.

Answer :  Hannah is likely to be incorrect because 9 is not contained in the interval. ( B )

Step-by-step explanation:

The statement that is supported by the interval in Hannah's claim is that

Answer:

y = [tex](\frac{1}{2})^{-x} +4[/tex]

Step-by-step explanation:

In order to achieve the following transformation we need to do the following. To get the graph to be reflected accross the y-axis we need to change the sign of the x variable. Since the x-variable in this scenario is a positive we would change it to a negative. Next, we want to shift the graph 4 units up. To do this we simply need to add 4 to the entire equation. This would result in the following equation.

y = [tex](\frac{1}{2})^{-x} +4[/tex]

Both of these graphs can be seen in the image below.

therefore 35% of 65 is 22.75%

Answer:

f(3) = 7

Step-by-step explanation:

f(x) = 2x + 1

f(3) = 2(3) + 1

f(3) = 6 + 1

Substitute the 3 in for x.

f(3) means that x is equal to 3.

This just means we substitute the value of 3 into the f(x) = 2x+ 1 to get

f(x) = 2(3)+ 1,

f(3) = 2(3)+ 1,

f(3) = 6+ 1,

f(3) = 7

Step-by-step explanation:

Answer:

To convert miles to cm, multiply the mile value by 160934.4. For example, to find out how many centimeters there are in 2 miles, multiply 2 by 160934.4, that makes 321868.8 cm in 2 miles.

multiply 2 by 160934.4, which is

321868.8 cm in 2 miles.

To convert a mile to a centimeter, multiply the length by the conversion ratio. The length in centimeters is equal to the miles multiplied by 160,934.4.

The distance in km is equal to the distance in miles multiplied by 1.609344. Since 1 mile is equal to 1.609344 km, that's the conversion ratio used in the formula.

Option B is correct. The measurement of the angle m in the circle given is 56degrees

Geometry deals with the measurement of properties of lines, solids, and angles.

The diagram given in the question is a circle. To get the value of d, we will use one of the circle theorems which states;

[tex]75=\frac{1}{2} (m\angle d - 94)[/tex]

Cross multiply

[tex]75 \times 2 = m \angle d - 94\\150=m \angle d +94\\m \angle d = 150 - 94\\m \angle = 56^0[/tex]

Hence the measurement of the angle m is 56degrees

we need cos c for this

h= 26 which is always the longest side of the triangle

b= 10

p=24

these both can be switched depending on which angle the question is talking about in this case its angle C so 10 is the base, if it was angle a 24 would have been the base
