Well i don't know if this will help but slope intercept form


y=mx+b


M-slope
B-Y intercept
and
(x,y)- would be any point on the graph and if you were to plug those points in for x and y the equation would solve if done properly

insens350 [35]

Answer:

\bar X= \frac{20*20 +12*30 +7*10 +5*15 +6*10}{20+30+10+15+10}

\bar X = \frac{965}{85}= 11.353

Step-by-step explanation:

For this case we have the following data:

Days to Maturity       Dollar Value $ Millions)

    20                                     20

    12                                      30

    7                                        10

    5                                        15

    6                                        10

For this case the definition of weigthed mean is given by:

\bar X = \frac{\sum_{i=1}^n w_i x_i}{\sum_{i=1}^n w_i}

Where w_i , i=1,...,n represent the weight of each value and x_i , i=1,...,n represent the observations (Days to maturity)

Our interest is the number of days so then our weighting variable would be the dollar Value, so then we can find the weighted mean like this:

\bar X= \frac{20*20 +12*30 +7*10 +5*15 +6*10}{20+30+10+15+10}

\bar X = \frac{965}{85}= 11.353

navik [9.2K]

Answer:

$450. The amount Antonio bought the tv for was $450.

Step-by-step explanation:

If all the tv's are 30%, multiple 30 by the price of the tv he wants, giving you 45000. Then, divide by 100 because a percent is out of a hundred, giving you $450

Formula:

(30x1500)/100

1. A penny is dropped from the top of the empire state building. The function h(t) = -16t^2 +1250 describes the height of the pe
liubo4ka [24]

Answer: 8.83\ s

Step-by-step explanation:

Given

Height of the dropped penny is given by

h(t)=-16t^2+1250

When penny hit the ground, h(t)=0

\therefore -16t^2+1250=0\\\Rightarrow 16t^2=1250\\\\\Rightarrow t^2=\dfrac{1250}{16}\\\\\Rightarrow t=\sqrt{\dfrac{1250}{16}}\\\\\Rightarrow t=8.83\ s

Thus, it takes 8.83 s to hit the ground.
