Answer:

1800 cubic in.

Step-by-step explanation:

Because the height is 1D, when it is multiplied by 10, the volume is multiplied by 10, so the answer is 180 cubic in. * 10 or 1800 cubic in.

Random sample of n=1300 registered voters and found that 670 would vote for the republican candidate in a state senate race. let

Misha Larkins [42]

We need to test the hypotheses:

$H_0:p=0.5\\ H_1:p>0.5$

The $(1-\alpha )100\%$ confidence interval for proportion is

$p \pm z_{\alpha/2} \sqrt{ \frac{p(1-p)}{n} }$ .

Here $p=\frac{670}{1300} =0.5154,n=1300,\alpha =0.05$

The z value to be used is 1.96.

The 95% CI is

$0.5154 \pm 1.96 \sqrt{ \frac{0.5154(1-0.5154)}{1300} } \\(0.488,0.543)$ .

Since 0.5 lies in the interval (0.488,0.543), we cannot reject the null hypothesis with 95% confidence.

Can you help pls jhgyihjopk[[knbh

Answer:

The lower right table

Step-by-step explanation:

The table of that's the right answer consists of f(x) and x points that when plugged into the equation make the equation equal.

Let's go through each of the tables to check.

Upper Left Table:

(Remember that f(x) and y are interchangeable)

- Let's plug in the first paired set (0,6) into the equation

$y = -2x + 6 \\6 = -2(0) + 6\\6 = 6$

So, this one seems right so far. It also let's us eliminate some answers!

The upper right and lower left tables can't be right because in order for the equation to be equal, f(x) has to be 6 when x equals 0

Let's plug more paired sets into the equation from the upper left table

$y = -2x + 6\\10 = -2(2) + 6 \\10 = -4 + 6 \\10 = 2$

This doesn't work so let's check to see if the lower right table is correct!

$y = -2x + 6 \\2 = -2(2) + 6\\2 = -4 + 6\\2 = 2$

Since the equation is equal, this has to be the right answer!

Hope this helps!!

v = 54 and a way you could have don this is you could use cross mutipalacation

and multiply 48 by 9 and 8 times v then you can use the inverse operation divide 432 by 8 getting v alone and there is your answer
