Two binders costs$4.36. how many bindees can buy with $55?​
Reil [10]

Answer:

Step-by-step explanation:

First you need to find the price for one binder. If 2 binders cost 4.36 you have to divide by 2 to find the price for 1. You should get 2.18. Then you have to see how many times you can multiply 2.18 without having the product go over 2.18. 2.18 • 22 = 47.96, the number closest to 50 without going over. Therefore, she can buy 22 binders.

9. Stan’s Deli is situated inside a large industrial park. The weekday gross sales at Stan’s average $1,240, with a standard dev
mr Goodwill [35]

Answer:

0.9792

Step-by-step explanation:

Data provided in the question:

Average gross sales = $1,240

Standard deviation = $180

sample size = 40

Now,

standard deviation of sample average

= \frac{\textup{Standard deviation}}{\sqrt{n}}

= \frac{180}{\sqrt{40}}

= 28.46

Now,

z value for 1200 = \frac{(1200-1240)}{28.46} = -1.4,

and,

p value for (z = -1.4) = 0.0808

therefore,

P(average < $1200) = 0.0808

Thus,

probability that the average over the next 40 weekdays will exceed $1,200

= 1 - 0.808

= 0.9792

The interior angle of the regular octagon below measures 135º, and the
rodikova [14]

Answer:

D

Step-by-step explanation:

Since the shape won't change, it won't deform, nothing will happen to the interior angle.

This figure is symmetric and not deformed, so the measure of the interior angle won't change no matter how many times you rotate it.

So the interior angle would still be 135º.

Correct answer D
