Take 110 and divide it by 5.75 and you should get your answer.
It would take about 11 hours of work to make $110

Find the 23rd term in the sequence 2, 6, 10, 14, 18, 22

tatiyna

Hello!

First you have to find the rule that the sequence is going by

6 - 2 = 4
10 - 6 = 4
14 - 10 = 4
18 - 14 = 4

They add 4 to the number every time

To find the 23rd term you multiply the rate by the term you want

23 * 4 = 92

Next you subtract the first number

92 - 2 = 90

The answer is 90

Hope this helps!

Scores on the SAT Mathematics test are believed to be normally distributed. The scores of a simple random sample of five student

AysviL [449]

Answer:

The mean calculated for this case is $\bar X=584$

And the 95% confidence interval is given by:

$584-2.776\frac{86.776}{\sqrt{5}}=476.271$

$584+2.776\frac{86.776}{\sqrt{5}}=691.729$

So on this case the 95% confidence interval would be given by (476.271;691.729)

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

In order to calculate the mean and the sample deviation we can use the following formulas:

$\bar X= \sum_{i=1}^n \frac{x_i}{n}$ (2)

$s=\sqrt{\frac{\sum_{i=1}^n (x_i-\bar X)}{n-1}}$ (3)

The mean calculated for this case is $\bar X=584$

The sample deviation calculated $s=86.776$

In order to calculate the critical value $t_{\alpha/2}$ we need to find first the degrees of freedom, given by:

$df=n-1=5-1=4$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and we can use excel, a calculator or a tabel to find the critical value. The excel command would be: "=-T.INV(0.025,4)".And we see that $t_{\alpha/2}=2.776$

Now we have everything in order to replace into formula (1):

$584-2.776\frac{86.776}{\sqrt{5}}=476.271$

$584+2.776\frac{86.776}{\sqrt{5}}=691.729$

So on this case the 95% confidence interval would be given by (476.271;691.729)

HELP PLEASEEEEEEEEEEEEEE

Katena32 [7]

Answer:

C

Step-by-step explanation:

The net diagram shows two triangles and three rectangles. The relevant area formulas are ...

A = 1/2bh . . . . . . area of a triangle

A = bh . . . . . . . . area of a rectangle

The two triangles are shown with a base of 4 and a height of 3 1/2, so you expect the area expression to have a term that looks like ...

2(1/2 × 4 × 3 1/2)

The three rectangles are shown with dimensions 8 and 4, so you expect the area expression to have at term that looks like ...

3(4 × 8)

Only one of the area expressions has both of these terms: the third choice.
