Answer:

${ \tt{3x - 3y = 24}} \\ { \tt{ 3(x - y) = 24}} \\ \\ { \tt{ \frac{3(x - y)}{3} = \frac{24}{3} }} \\ \\ { \tt{x - y = 8}} \\ \\ { \tt{x = 8 + y}}$

Harman [31]

here we have 3X to 5 seventh power in radical form

$3x^{5/7}$

we need write this in radical form we knwo that $x^{1/2} =\sqrt{x}$

so $3x^{5/7} =\sqrt[7]{3x^{5}}$

this will be the radical form .

Find the value of x in similar polygons below

muminat

Answer:

Choice A

Step-by-step explanation:

When you have two shapes that are similar their sides are always proportional. So all we have to do is set up a proportion.

$\frac{18}{4.5}=\frac{x}{1.5}$

Now we cross multiply and solve

$27=4.5x\\x=6$

And that's it x equals 6 feet.

A vending machine operator has determined that the number of candy bars sold per week by a certain machine is a random variable

docker41 [41]

Answer:

The answer is below

Step-by-step explanation:

Let Y represent the profit per day, and x represent the number of bar sold per day. Hence:

Y = 0.25x - 2

a) The mean is given as:

$\mu_y=E(Y)=E(0.25X-2) = 0.25E(X)-2\\\\But\ E(X)=mean\ of\ machine=125. Hence:\\\\E(Y)=0.25(125)-2=29.25\\\\E(Y)=\$29.25$

b) The standard deviation of y is:

$\sigma_y=var(0.25X-2)\\\\\sigma_y=0.25\sigma(X)\\\\but\ \sigma_X=7,hence:\\\\\sigma_y=0.25(7)=1.75\\\\\sigma_y=\$1.75$
