The following gives the number of pints of type a blood used at woodlawn hospital in the past 6 weeks. week of: pints used: | 31 360september 7 389september 14 410september 21 381september 28 368october 5 374a. forecast the demand for the week of october 12 using a 3-week moving average. b. use a 3-week weighted moving average, with weights of .1, .3, and .6 using .6 for the most recent week. * then, forecast demand for the week of october 12.c. compute the forecast for the week of october 12 using exponential smoothing with a forecast for august 31 of 360 and a=.2

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
