Answer:

Step-by-step explanation:

9x - 4 + 5x + 16 = 180

14x + 12 = 180

14x = 168

x = 12

Answer:

x=12

Step-by-step explanation:

We know that \ell\parallel m.

Then by the properties of a transversal cutting a pair of parallel lines, we can write:

(9x-4)+(5x+16)=180

The property used here is the Consecutive Angles Property. The two consecutive angles are supplementary.

Now, we can solve for <em>x</em>. Rearrange:

(9x+5x)+(-4+16)=180

Combine like terms:

14x+12=180

Subtract 12 from both sides:

14x=168

Divide both sides by 14:

x=12

So, the value of <em>x</em> is 12.

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.

X+3y=3<br> 2x-4y=6<br><br> solve the equations
Gelneren [198K]
Subtract the second equation from double the first equation:

2x+6y-2x-(-4y)=0

10y=0

Therefore, y=0.  Substituting this into the first equation, we see that:

x+3(0)=3

x=3

Therefore, x=3.  The solution to this system is x=3, y=0, or (3, 0).
