Answer:

I think it would be 350$

Step-by-step explanation:

ok so you have to buy 10 shirts so you need to set up your problem which would be 10(12+8+15)

Then you would have to actually distribute which would give you 120+80+150

Finally you just add all of your numbers together which would be 350$

Answer:

Cost of 10 sets of uniform is $350.

Step-by-step explanation:

We are given the following information in the question:

Cost of one volleyball = $15

Cost of one pair of shorts = $12

Cost of one pair of socks = $8

We have to find cost for 10 sets of such uniform. This can be done with the help of the distributive property.

The distributive property helps us to multiply a sum by multiplying each addend separately and then add the products.

a\times (b+c) = (a\times b) + (a\times c)

Cost for 10 pairs of uniform =

10\times \text{Cost of 1 set of uniform}\\=10\times (15+12+8)\\=(10\times 15) + (10\times 12) + (10\times 8)\\ = 150 + 120 + 80\\= 350

Hence, cost of 10 sets of uniform is $350.

When you are dividing fractions you just flip the second fraction upside down and multiply the two fractions
So the first is
½ x 6/1 = 6/2 = 3

For the second you write them as improper fractions then do the same
So it is
3/2 / 1/8 = 3/2 x 8/1 = 24/2 = 12

So the answer to the first question is 3 and the second is 12

Can someone help me with factoring by grouping
Wittaler [7]

Factor : x^2+3x-10

Answer = (x - 2)(x + 5)

Explanation:

Y = x^2 + 3x - 10.

Find 2 numbers knowing sum (3) and product (-10).

Factor pairs of (-10) -> (-1, 10)(-2, 5). This sum is 3 = b. The 2 numbers are: -2 and 5.

y = (x - 2)(x + 5).

julsineya [31]

Answer:

n=\frac{0.5(1-0.5)}{(\frac{0.01}{2.58})^2}=16641  

And rounded up we have that n=16641

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".  

The population proportion have the following distribution

p \sim N(p,\sqrt{\frac{p(1-p)}{n}})

Solution to the problem

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by \alpha=1-0.99=0.01 and \alpha/2 =0.005. And the critical value would be given by:

z_{\alpha/2}=-2.58, t_{1-\alpha/2}=2.58

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

And on this case we have that ME =\pm 0.01 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

For this case we can use as estimator for the proportion \hat p =0.5, since we don't have any other previous info. And replacing into equation (b) the values from part a we got:

n=\frac{0.5(1-0.5)}{(\frac{0.01}{2.58})^2}=16641  

And rounded up we have that n=16641
