SOMEONE PLEASE ANSWER ASAP FOR BRAINLIEST!!!!!
kaheart [24]

Answer:

 D     b = -2E +212

Step-by-step explanation:

The slope is given by -2 for every 1000 ft

The initial value is 212 degrees

We can use

y = mx+b  where m is the slope and b is the initial value

y = -2x +212

We are at an elevation of E thousand ft

Replace x with E

y = -2 *E +212

b is the boiling point at this elevation

We  replace y with b

b = -2E +212

Solve the equation 12x-14=4x+10​
ziro4ka [17]

Answer:

x=3

Step-by-step explanation:

12x-14=4x+10​

Subtract 4x from each side

12x-4x-14=4x-4x+10​

8x - 14 = 10

Add 14 to each side

8x - 14+14 = 10+14

8x = 24

Divide each side by 8

8x/8 = 24/8

x = 3

13. Given the following historical data and weights of .5, .3, and .2, what is the three-period weighted moving average forecast
Ostrovityanka [42]

Answer:

b. 144.8

Step-by-step explanation:

When calculating the moving average estimate of an observation , each of the observations are usually computed with the same weighted . In some cases, it is  beneficial to assign different  weight on the observations  such that the observation closer to the time period being forecast, has higher weight.  This is refer to as weighted moving average technique. The sum of the individual weight in a weighted moving average technique must equal to 1.

The three-period weighted moving average forecast for period 5 = 144*0.5 + 148 *0.3 + 142 *0.2 =  144.8
