We are interested in determining whether or not the variances of the sales at two small grocery stores are equal. A sample of 21

katen-ka-za [31]

Answer:

$F=\frac{s^2_A}{s^2_B}=\frac{28.284^2}{20^2}=1.99996$

Step-by-step explanation:

Data given and notation

$n_A = 21$ represent the sampe size for A

$n_B =16$ represent the sample size for B

$s_A = 28.284$ represent the sample deviation for A

$s_B = 20$ represent the sample deviation for B

$\alpha$ represent the significance level provided

F test is a statistical test that uses a F Statistic to compare two population variances, with the sample deviations s1 and s2. The F statistic is always positive number since the variance it's always higher than 0. The statistic is given by:

$F=\frac{s^2_1}{s^2_2}$

Solution to the problem

System of hypothesis

We want to test if we have the same variation, so the system of hypothesis are:

H0: $\sigma^2_A = \sigma^2_B$

H1: $\sigma^2_A \neq \sigma^2_B$

Calculate the statistic

Now we can calculate the statistic like this:

$F=\frac{s^2_A}{s^2_B}=\frac{28.284^2}{20^2}=1.99996$

Solve 5(2y+1)=4y+10. this is for algebra 1

jolli1 [7]

Answer:

$y=5/6\approx0.83$

Step-by-step explanation:

So we have the equation:

$5(2y+1)=4y+10$

First, let's distribute the left side of our equation:

$5(2y)+5(1)=4y+10$

Multiply:

$10y+5=4y+10$

Now, let's isolate the y-variable. Subtract 4y from both sides:

$(10y+5)-4y=(4y+10)-4y$

The right side cancels. Subtract on the left. So:

$6y+5=10$

Now, subtract 5 from both sides:

$(6y+5)-5=(10)-5$

The left side cancels. Subtract on the right:

$6y=5$

Now, divide both sides by 6. So:

$\frac{6y}{6}=\frac{5}{6}$

The left will cancel. Therefore:

$y=5/6\approx0.83$

And we're done!

Which is true about the volume or surface area of these prisms?

GrogVix [38]

The correct answer is B- The surface area of B is greater than the surface area of A. I got this answer because...

Figure A's Volume= 60

Figure B's Volume= 60

Figure A's Surface Area= 104

Figure B's Surface Area= 248

So because the volumes are the same I knew it was not C or D, and then I solved the Surface Area for figures a and b and knew the correct answer is B.

Hope that helps. :)
