music school has budgeted to purchase 3 musical instruments. They plan to purchase a piano costing $3,000, a guitar costing $650, and a drum set costing $800. The mean cost for a piano is $3,500 with a standard deviation of $2,000. The mean cost for a guitar is $600 with a standard deviation of $250. The mean cost for drums is $1000 with a standard deviation of $125. (Enter your answers to two decimal places.)

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

unless if u could do my questions, if not i wouldn't want to
