What is 34% of 60000000

Ainat [17]

(Lets hope i'm right :p)

The first thing you do is make "34%" into a fraction. That would be 1/34.

After, you would multiply.

1/4 x 60000000/1 = ?

(Use cross multiply if you know)

60000000 divided by 4 = 15000000

1/1 x 15000000/1 = 15000000/1 OR 15000000

Answer: 15000000/1 or 15000000

The area of a rectangle is 105 square units. Its width measures 7 units. Find the length of its diagonal. Round to the nearest t

mezya [45]

Answer:

16.6

Step-by-step explanation:

The rectangle has an area of 105. It's width is 7.

1: Find the length

$\frac{area}{width}$ =length

$\frac{105}{7}$ = 15

Length=15

2: Pythagorean theorem

$a^{2} +b^2=c^2$

$7^{2}$ + $15^2=c^2$

49+225= $c^2$

275= $c^2$

$\sqrt{275}$ = $\sqrt{c^2\\}$

16.55≈c

Rounded to nearest tenth

16.6

A marketing researcher wants to find a 96% confidence interval for the mean amount those visitors spend per person per day while

ki77a [65]

Answer:

$n=(\frac{2.054(12)}{4})^2 =37.97 \approx 38$

So then the minimum sample to ensure the condition given is n= 38

Step-by-step explanation:

Notation

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

$\mu$ population mean (variable of interest)

$\sigma=12$ represent the population standard deviation

n represent the sample size

ME = 4 the margin of error desired

Solution to the problem

When we create a confidence interval for the mean the margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (a)

And on this case we have that ME =4 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=(\frac{z_{\alpha/2} \sigma}{ME})^2$ (b)

The critical value for 96% of confidence interval now can be founded using the normal distribution. The significance is $\alpha=1-0.96 =0.04$ . And in excel we can use this formula to find it:"=-NORM.INV(0.02;0;1)", and we got $z_{\alpha/2}=2.054$ , replacing into formula (b) we got:

$n=(\frac{2.054(12)}{4})^2 =37.97 \approx 38$

So then the minimum sample to ensure the condition given is n= 38
