It would be 143 because if you were to multiply 100*11 = 1100 so doing the same for 13*11 would equal 143

15. Two methods are used to predict how many customers will call in for help in the next four days. The first method predicts th
Marizza181 [45]

Answer:

Method 1 has bigger forecast bias.

Step-by-step explanation:

We are given the following information in the question:

Actuals:

23, 10, 15, 19

Method 1 prediction:

23, 5, 14, 20

Residuals = Predicted - Actuals

Sum of square of errors:

=(23-23)^2+(5-10)^2+(14-15)^2+(20-19)^2\\= 27

Mean squared error:

\dfrac{\text{Sum of squares}}{n} = \dfrac{27}{4} = 6.75

Method 2 prediction:

20, 13, 14, 20

Residuals = Predicted - Actuals

Sum of square of errors:

=(20-23)^2+(13-10)^2+(14-15)^2+(20-19)^2\\= 20

Mean squared error:

\dfrac{\text{Sum of squares}}{n} = \dfrac{20}{4} = 5

Since, mean square error of method 2 is less as compared to method 1, method 1 has bigger forecast bias.

The ratio of the angles in a triangle is 2:3:5. Find the measure of each angle. Measurements are all in degrees.
Julli [10]
Angles in a triangle add up to be 180 degrees. 2x+3x+5x= 180
10x=180
x=18
2(18) = 36
3(18) = 54
5(18)= 90

The volume of a gas is 10.0 liters and its pressure is 1.5 atm. If the pressure is decreased to 0.75 atm,
JulsSmile [24]

Answer:

The new volume is 20litres

Step-by-step explanation:

This problem bothers on the expansion of gases

According to Boyle's law

The volume of a given mass of gas at constant temperature is inversely proportional to the pressure

P∝1/v

Pv= constant

Given data

P1= 1.5atm

v1 = 10 litter

P2=0.75atm

v2=?

Applying P1v1= P2v2

v2= P1v1/P2

v2= 1.5*10/0.75

v2= 15/0.75

v2= 20litres
