Using a weighted moving average with weights of 0.60 for June, 0.30 for May, and 0.10 for April, find the July forecast.
Answer: the July forecast is 15
Step-by-step explanation:
Given that;
Month Demand Weights
January 12
February 11
March 15
April 12 0.10
May 16 0.30
June 15 0.60
July ? ?
Formula for calculating weighted moving average is
Ft = w1A_t-1 + w2A_t-2 ............+ wnA_t-n
w1, w2, wn is the weight assigned to the period t-1, t-2, t-n respevtively
A_t-1, A_t-2, A_t-n is the demand period t-1, t-2, t-n respevtively
and n is the total number prior periods in the forecast.
so we just substitute our values into the equation
Forecast(July) = (15 × 0.6) + (16 × 0.30) + ( 12 × 0.10)
= 9 + 4.8 + 1.2
= 15
Therefore the July forecast is 15
What is an equivalent exponential equation? log5(125)=−2
Answer:
Step-by-step explanation:
[tex]log_{a} c = b[/tex] ⇔ [tex]a^{b} = c[/tex]
There is no exponential equation equivalent to given logarithm's equation.
[tex]log_{5} 125 \neq -2[/tex]
[tex]5^{-2}[/tex] = [tex]\frac{1}{25}[/tex] ≠ 125
May be you made mistake and instead of 1/25 you just typed 125 ??? Oh, well ......

Answer:
8. The coordinates (0,0) represent the fact that when 0 minutes has passed, the horses have gone 0 miles because they hadn't started yet.
9. From the graph, it looks like horse A takes 4 minutes and horse B takes 2.5 minutes (aka 2 minutes and 30 seconds) to travel 1 mile.
10. For A: y = (1/4)x
For B: y = (2/5)x
11. For A: 3 miles
For B: (24/5) miles, or 4 and (4/5) miles.
12. Can't see the entire problem sorry.
Step-by-step explanation:
9. You find this by going to y=1 and look towards the right till you find the point the line intersects with y=1. Then find the x value by finding the corresponding number on the x axis.
10. A linear function will look something like this: y = mx+b, where y is the y value, x is the x value, m is the slope, and b is the y-intercept. Since both lines start from 0, you don't have to write the y-intercept since there's no point in writing +0. To find slope, you find delta y over delta x. Basically just find the difference of two y values and the difference of two x values from the same coordinate in the same order. I know that sounds really confusing but your teacher will probably teach this later on.
11. x represents the time, so just substitute x as 12 in the equation.

What is Unitary method?
In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The price of 8 tokens is $4.40.
In order to find the cost for 19 tokens the unitary method is used as,
The cost for 1 token = $4.40/8
= $5.5
So, the cost for 19 tokens is 19 × 5.5 = $104.5
Hence, the cost for 19 tokens is $104.5.

X= 2y-5
4x+3y=-9
Step-by-step explanation:
x=2y-5 - equation 1
4x+3y=-9 -equation 2
Replace equation 1 in equation 2
4(2y-5)+3y=-9
8y-20+3y=-9
11y=-9+20
11y=11
y=11/11
y=1
If y=1, therefore x=2(1)-5=-3
x=-3,y=1

Jasmin can walk 1/4 mile every 1/5 hour. At this rate, how far can Jasmin
walk in one hour?
Answer:
hope this helps :)
Step-by-step explanation:
Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.
So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour

A class has 30 students. 18 are boys. what id the ratio of boys to girls? (you must simplify)
Answer:
number of students =30
boys =18
girls =30-18=12
therefore,the ratio of boys :girls
=18:12
then simpilyfing, =3:2
The ratio of the number of boys to girls in the class is 3 : 2
Total number of students = 30
Number of boys = 18
Nunber of girls = 30 - 18 = 12
The ratio of boys to girls :
Number of boys : Number of girls 18 : 12Simplify to lowest term :

What is the solution to the inequality 7<=-3x-4
Answer:
The nearest option is -3 (negative 3)
So, Option B is correct.
Step-by-step explanation:
We need to solve the inequality [tex]7 \leq -3x-4[/tex]
Solving:
Step 1: Switching sides of inequality and reversing the inequality
[tex]-3x-4\geq 7[/tex]
Step 2: Adding 4 on both sides
[tex]-3x-4+4\geq 7+4\\-3x\geq 11[/tex]
Step 3: Dividing both sides by -3 and reversing the inequality
[tex]\frac{-3x}{-3}\leq \frac{11}{-3} \\x\leq -3.6\\[/tex]
The nearest option is -3 (negative 3)
So, Option B is correct.
