y<6

Step-by-step explanation:

1 /3 y +  1/4  >  3 /8y

1 /3 y +  1/4  −  3/ 8 y > 3/ 8 y −  3/ 8 y

− 1 /24 y +  1 4  > 0

−1 /24 y +  1 /4  −  1/ 4  > 0 −  1 /4

−1 /24 y >  −1/ 4

Multiply both sides by 24/(-1).

If the sum of the measures of the interior angles of a polygon is 1980 degrees, how many sides does it have? I need an explanation to this!

Answers

Answer:

It has 13 sides.

Step-by-step explanation:

The equation for total interior angle is x = 180(n - 2)

fill it out and solve

1980 = 180(n - 2)

1980 = 180n - 360

2340 = 180n

n = 13

Can someone please help me with this questions The points H,I,J and K all lie on the same line segment, in that order, such that the ratio of HI:IJ:JK is equal to 2:2:3. If HK=49, find IJ.

Answers

Answer:

IJ = 14

Step-by-step explanation:

If the point HIJK all lies on the same line, then HI + IJ + JK = HK

2 + 2 + 3  = HK

HK = 7

Since the total length is HK

IJ = ratio of IJ/Total ratio * HK

IJ = 2/7 * 49

IJ = 2 * 7

IJ = 14

Hence the length of IJ is 14

An online retailer has two warehouses, M and N, where customers' orders are packaged and shipped. The number of orders per day for warehouse M has a mean of 1,417.31 and a standard deviation of 67.54. The mean number of orders per day is 1,505.39 for warehouse N with a standard deviation of 67.70. Explain how the number of orders per day for warehouse M compare to the number of order per day for warehouse

A The number of orders per day for warehouse N is less on average than the number of orders per day for warehouse M. The standard deviation for the number of orders per day in warehouse N is greater than the standard deviation in warehouse M.

BThe number of orders per day for warehouse N is greater on average than the number of orders per day for warehouse M. The standard deviation for the number of orders per day in warehouse N is about the same as in warehouse M.

C The number of orders per day for warehouse M is about the same on average to the number of orders per day for warehouse N. The standard deviation for the number of orders per day in warehouse M is greater than the standard deviation for warehouse N.

D The number of orders per day for warehouse M is greater on average than the number of orders per day for warehouse N. The standard deviation for the number of orders per day in warehouse N is about the same as in warehouse M.

Answers

Answer:

B. The number of orders per day for warehouse N is greater on average than the number of orders per day for warehouse M. The standard deviation for the number of orders per day in warehouse N is about the same as in warehouse M.

Step-by-step explanation:

Wearhouse M has an average of 1,417.31 orders shipped per day, and Warehouse N has an average of 1,505.39 packages shipped per day. meaning that Wearhouse N has a greater mean (or average) compared to Wearhouse M.

Wearhouse M has a standard deviation (The safety net of how much the average can change) of 67.54 and Wearhouse N has a standard deviation of 67.70 which means that these are practically the same number.
