Answer:
6
Step-by-step explanation:
20/ 100 x 30 = 6
<span>Approximately 238 pages fall within the second standard deviation of the mean. The 68-95-99.7 rule gives that in a normal distribution, about 68% of the data fall within the first standard deviation, and 350*0.68=238. 350*0.95=332, so about 332 pages fall within the second standard deviation, and 350*99=348.95 pages fall within the third standard deviation.</span>
Answer:
200 pairs of sandals
Step-by-step explanation:
Represent the sandals with x and the running shoes with y.
In a typical month:

In April

Required
The number of sandals in a typical month
<u>In a typical month:</u>
If 1 sandal costs 2.50, then x costs 2.50x
If 1 running shoe costs 4, then y costs 4y
The total is:

<u>In April:</u>
If 1 sandal costs 2.50, then 2x costs 5x ---- <em>we used 2x because the pairs is doubled </em>
If 1 running shoe costs 4, then y costs 4y
The total is:

The equations are:


Subtract




Answer:
Choice A.......< B is 147 degrees
Step-by-step explanation:
The total sum of the interior angles of a pentagon is 540 degrees
...So let's count the angles that we already have:
<A is 90
<B is ?
<C is 105
<D is 108
<E is 90
Noticed that both angles A and E are 90 since they have that little square that represents a straight angle.
Let's find the value for <B
90+ x + 105 + 108 + 90= 540
393 + x= 540
x= 540 -393
x = 147
So angle B is 147 degrees
Graph using the slope and y-intercept.
Slope: 1.5
Y-intercept: 18
