Answer:

3x×2c+1

Step-by-step explanation:

6x+15 =4c-12

$\frac{6x + 15}{4c - 12} = \frac{4c - 12}{4c - 12}$

$\frac{6x + 15}{4c - 12}$

$\frac{3x + 5}{2c - 4}$

$3x + 5 \div 2c - 4$

$3x \times 2c + 5 - 4$

$3x \times 2c + 1$

Answer:

256 degrees.

Step-by-step explanation:

The figure is a parallelogram so m < 1 = 180-52 = 128 degrees (same side angles).

Also m < 2 = m < 1 (opposite angles of a parallelogram), so their sum is 2*128

= 256 degrees.

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.
