Answer:

<em><u>A theater has </u></em><em><u>60 seats</u></em><em><u> in the first row, 68 seats in the second row, 76 seats in the third row,</u></em>

<em><u>and so on in the same i</u></em><em><u>ncreasing pattern</u></em><em><u>. If the theater has</u></em><em><u> 20 rows of seats, how many seats are in the theater?</u></em>

220 seats in the theater.

So if the increasing pattern is +8, and we need to determined how many seats there will be if there where 20 rows, then you would need to multiply.

1. 8 x 20 = 160

2. 160 + 60 = 220

The mean vitamin C level for 20 dogs was 7.6 milligrams per liter, with a standard deviation of 2.1 milligrams per liter.
SpyIntel [72]

Answer:  The mean increases.

Step-by-step explanation:

The value of 0.9 mg/L is very low compared to a means of 7.6 mg/L with a standard deviation of 2.1 mg/L.  It seems as though it is an outlier that is suffiently different from the others, and probably should be dropped from the data set.  That would do 2 things:  1) the stabdard deviation will likely decrease, indicating a more confident data set, and 2) the mean vitamin C level will increase.

How many times does 96 go into 195
Anna007 [38]
You can also do the division with remainders to find the answer:

195 ÷ 96 = 2,041666666666667

So you can clearly see that there are more than two but less than three 96s in 195. So multiply 96 by 2 and then substract the result from 195 to find the remainder:

96 * 2 = 192
195 - 192 = 3

It means that in 195 there will fit two 96s with a remainder of 3.

We can also write it as two 96s and 3/96, what can be further simplified to two 96s and 1/32.
