What is the power of 10 when 75,200 is written in scientific notation?

2 answers:

6 0

The correct answer is:
4.

Explanation:
In scientific notation, we place the decimal behind the first non-zero digit in the number. For 75,200, this is 7.

We then count the number of places we must move the decimal to place it here. In this problem, we move the decimal 4 places. This is the exponent for 10.

Equilateral triangles do not have right angles, because then the angles wouldn't be equal!

Both acute and Equilateral have angles smaller than 90!

A hotel manager believes that 27% of the hotel rooms are booked. If the manager is correct, what is the probability that the pro

AlladinOne [14]

Answer:

The probability that the proportion of rooms booked in a sample of 423 rooms would differ from the population proportion by less than 6% is 0.9946.

Step-by-step explanation:

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

The mean of this sampling distribution of sample proportion is:

$\mu_{\hat p}=p$

The standard deviation of this sampling distribution of sample proportion is:

$\sigma_{\hat p}=\sqrt{\frac{\hat p(1-\hat p)}{n}}$

The information provided here is:

p = 0.27

n = 423

As n = 423 > 30, the sampling distribution of sample proportion can be approximated by the Normal distribution.

The mean and standard deviation of the sampling distribution of sample proportion are:

$\mu_{\hat p}=p=0.27\\\\\sigma_{\hat p}=\sqrt{\frac{\hat p(1-\hat p)}{n}}=\sqrt{\frac{0.27\times(1-0.27)}{423}}=0.0216$

Compute the probability that the proportion of rooms booked in a sample of 423 rooms would differ from the population proportion by less than 6% as follows:

$P(|\hat p-p|$

$=P(0.27-0.06$

*Use a z-table.

Thus, the probability that the proportion of rooms booked in a sample of 423 rooms would differ from the population proportion by less than 6% is 0.9946.

Describe the process for graphing the equation y =-1/2x- 1

AysviL [449]

the formula is y=mx+b

m is the slope

b is the y-intercept form

so the -1 is the y-intercept form. so you need to start at that point on the y axis. then the slope which is -1/2 comes into play. in my school we use rise/run. so from the point you marked at -1 you will go down 1 and to the right 2 points then where you stop is your next point (mark it) keep doing that. also go up the other way from the -1 point. go up 1 and to the left 2. then connect all of your points with a line. I hope this helped.

sattari [20]

Answer:

From the attached graphic we see that

rhombus side = Sqr Root [(Long Diagonal / 2) ^ 2 + (Short Diagonal / 2) ^ 2]

rhombus side = Sqr Root [(24/2)^2 + (18/2)^2]

rhombus side = Sqr Root [144 + 81]

rhombus side = Sqr Root (225)

rhombus side = 15 feet
