Answer:

n= 5

Step-by-step explanation:

3.5 (10n + 2n-9) = 178.5

Divide 3.5 on both sides

10n + 2n -9 +51

Add like terms to get 12n

12n - 9 = 51

12n = 51 + 9

Add 51 and 9 to get 60

12n + 60

Divide 60 by 12 to get 5

n=5

Answer:

1436.76

Step-by-step explanation.

[tex]\frac{4}{3}\pi r^{3}[/tex]

that is the formula, with r being the radius.

then if you replace r with 7 that would be the answer.

pi, also equals 3.14159265359, or shortened 3.14.

so it would look like:

[tex]\frac{4}{3}*3.14*7^{3}[/tex]

Auto Praise for Cow - A Haiku

"The juxtaposition of cow and goat is truly inspired."

- The Daily Tale

"I don't like short poems. So why am I reviewing a haiku, you may wonder? Well, I liked the title - 'Cow'. It went down hill from there."

- Enid Kibbler

"Amazing how so few words can set a scene so perfectly. I close my eyes and all I can see is the baking christmastime."

- Hit the Spoof

"I felt that I was a cow. It was spooky. I hope to read more by Anonymous. Perhaps next time, something longer."

- Zob Gloop

"I've always wanted to write a haiku about a cow. I can't belive Anonymous has beaten me to it."

- Betty Borison

"Baking christmastime is a popular first line for a haiku. It's incredible how much diversity can be achieved with those final lines."

Answer:

112$

Step-by-step explanation:

First, find out how much she makes per hour:

70$ in 5 hours. Divide 70 by 5.

70/5 = 14

If she makes 14$ per hour, the equation to find 8 hours is 14*8

14*8 = 112

At the 95% confidence level, the margin of error for this survey, expressed as a proportion, is approximately 0.0288.

To calculate the margin of error for a survey expressed as a proportion, we need to use the formula:

Margin of Error = Critical Value [tex]\times[/tex] Standard Error

First, let's find the critical value.

For a 95% confidence level, we can refer to the standard normal distribution (Z-distribution) and find the z-value associated with a 95% confidence level.

The critical value for a 95% confidence level is approximately 1.96.

Next, we need to calculate the standard error.

The standard error for a proportion can be computed using the formula:

Standard Error [tex]= \sqrt{((p \times (1 - p)) / n)}[/tex]

Where:

p = proportion of respondents in favor of the plan

n = sample size

In this case, the proportion in favor of the plan is 37/185 = 0.2 (rounded to the nearest thousandth).

The sample size is 185.

Now we can calculate the standard error:

Standard Error [tex]= \sqrt{((0.2 \times (1 - 0.2)) / 185)}[/tex]

Simplifying further:

Standard Error ≈ [tex]\sqrt{((0.04) / 185)}[/tex]

Standard Error ≈ [tex]\sqrt{(0.0002162)}[/tex]

Standard Error ≈ 0.0147 (rounded to the nearest thousandth)

Finally, we can calculate the margin of error:

Margin of Error = 1.96 [tex]\times[/tex] 0.0147

Margin of Error ≈ 0.0288 (rounded to the nearest thousandth)

Step-by-step explanation:

Here, we want to find the value of x

To get this, we use one of the important circle theorems. This is the theorem of secant segments

We have this that;
