$15.35 - $10.58 = $4.77

The tee shirt would increase by $4.77 next year.

Find the midpoint of R(2,2) and S(-3,6)

musickatia [10]

Answer: (-0.5, 4)

Step-by-step explanation:

Midpoint formula: $(\frac{x1+x2}{2} ,\frac{y1+y2}{2} )$

(x1, x2)=(2, -3)

(y1, y2)=(2, 6)

-----------------------------------------------

$(\frac{x1+x2}{2} ,\frac{y1+y2}{2} )$

= $(\frac{2-3}{2} ,\frac{2+6}{2} )$

= $(\frac{-1}{2} ,\frac{8}{2} )$

= $(-0.5, 4)$

Hope this helps!! :)

Please let me know if you have any question or need further explanation

the equation of the line / is -3y+4x=9. write the equation of a line that is parallel to the line / and passes through the point

nekit [7.7K]

Hey!

So before trying to figure out the equation of the line, lets change -3y+4x = 9 into slope-intercept form:

-3y + 4x = 9

-3y = -4x + 9

y = (4/3)x - 3

Now that you have the equation in slope-intercept form we can find the equation of the line parallel to this. One thing that we are given from this equation is the slope of the line, the slope for two parallel lines are the same. So we know that the slope of the line is 4/3. We are also given another point on the line and we can plug this point in for y and x to find the y-intercept or b:

6 = (4/3)(-12) + b

6 = -16 + b

22 = b

Now that we know b, we have both the y-intercept and the slope so our equation would be:

y = (4/3)x + 22

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from ea

777dan777 [17]

Answer:

The mean and standard deviation of Y is $6.56 and $2.77 respectively.

Step-by-step explanation:

Consider the provided information.

Let Y represent their profit on a randomly selected pizza with this promotion.

The company is going to run a promotion where customers get $2 off any size pizza.

Therefore, $Y=\text{Profit}-\$2$

$Y=X-\$2$

So the mean will be reduced by 2.

$\mu_Y=\mu_X-\$2$

$\mu_Y =\$ 8.56 - \$2$

$\mu_Y =\$6.56$

If we add or subtract any constant number from a given distribution, then the mean is changed by the same number(i.e constant number) but the standard deviation will remain the same.

Therefore $\sigma_Y=\sigma_X=2.77$

Hence, the mean and standard deviation of Y is $6.56 and $2.77 respectively.
