It would be 820 because any number you have to round that ends in 4,3,2, or 1 will round down.

I need help please!!!! Jon buys t shirts online for his friends. the table below shows the cost including the shipping fee. writ
Ronch [10]
A t-shirt costs $12 per t-shirt plus $3 shipping. Write the equation that describes the total cost c for the number of t-shirts purchase t.

so equation
c = 3 + 12t

if t = 1 then c(cost) = 3 + 12(1) = 3 + 12 = 15
if t = 2 then c(cost) = 3 + 12(2) = 3 + 24 = 27
if t = 3 then c(cost) = 3 + 12(3) = 3 + 36 = 39
if t = 4 then c(cost) = 3 + 12(4) = 3 + 48 = 51

Answer:

a,b) x represents the general attitude of these students toward recreational reading.

c) The 10th percentile of sample means is 102.51.

d) P(x < 100) = 0.01390

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by

Z = \frac{X - \mu}{\sigma}

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.

In this case, we have that:

The mean score for this population of children was 106 points, with a standard deviation of 16.4 points, so \mu = 106, \sigma = 16.4.

a,b) What is x?

x represent the mean recreational reading attitude score for the sample. So x represents the general attitude of these students toward recreational reading.

c) What sample mean would be the cutoff for the bottom 10% of sample means. (You are being asked for the 10th percentile of sample means.)

This is the value of X when Z has a pvalue of 0.10.

Looking at the Z table, that is Z = -1.28.

We are working with the mean of the sample, so we have to find the standard deviation of the sample. That is

s = \frac{\sigma}{\sqrt{n}} = \frac{16.4}{\sqrt{36}} = 2.73

Z = \frac{X - \mu}{\sigma}

-1.28 = \frac{X - 106}{2.73}

X - 106 = -1.28*2.73

X = 102.51

The 10th percentile of sample means is 102.51.

d) Find P(x < 100).

This is the pvalue of Z when X = 100.

Z = \frac{X - \mu}{\sigma}

Z = \frac{100 - 106}{2.73}

Z = -2.20

Z = -2.20 has a pvalue of 0.01390.

So P(x < 100) = 0.01390.

Solve the following math problem and give me an example please C/-7+3.2=2.7
jasenka [17]
C/-7+3.2=2.7

Step 1) Add 7 to both sides because what you do to one side you must do to the other
         C/<u>-7</u>+3.2=<u>2.7</u>
          <u>  +7          +7
</u>          C/+3.2=9.7

Step 2) Subtract 3.2 from both side
          C/<u>+3.2</u>=<u>9.7
</u>          <u>    -3.2   -3.2
</u>              C/=6.5

Your answer is C=6.5<u>
