A dependent variable is a value that depends on how the other variables are controlled or manipulated.
Meanwhile, an independent variable, is as what its name suggests, is independent and doesn't change based on the value of other variables.
a.) The dependent variable is the number of glitter markers
b.) The independent variable is the number of gift bags
c.) The number of glitter markers Teresa needs to buy depends on the number of gift bags she has. She has to multiply
d.) The relationship is additive. The more gift bags Teresa has, the more glitter markers she has to buy.
The first time the band leader selects one member, the probability that either you or your brother gets selected would be 2 out of 80 or in fraction 2/80.
Now, once one of you gets chosen, for the next selection, there are only 79 members left and the probability that the remaining one (between you and your brother) gets selected after is 1/79.
So, if you are both to be selected, the combined probability for that to happen will be (2/80)(1/79) = 1/3160.
Therefore, the answer is 1/3160<span>.</span>
Answer:
0
Step-by-step explanation:
Slope is Rise over Run (y / x).
For 2 points, you would take the difference of y-coordinates and divide by the difference of x-coordinates.
(Y1 - Y2) / (X1 - X2)
Since both y-coordinates are the same (ten minus ten), your slope is zero (zero divided by anything is zero).
Answer:
$120.
Step-by-step explanation:
The amount he sells the tool kit for = 80 + 20% of 80
= 80 + 16
= $96.
Let m be the marked price, then
m - 0.20m = 96
0.8m = 96
m = $120.
