Answer:
B. -2/5
Step-by-step explanation:
For a "run" (x change) of 5, the "rise" (y change) is -2 units. Then the slope is ...
slope = rise/run = -2/5
Answer:
The probability of getting a black pen from the bag is 13.5%.
Step-by-step explanation:
To determine the percentage probability that a black pen will be obtained from the bag, the following calculation must be performed:
12 + 20 + 5 = 37
37 = 100%
5 = X
(5 x 100) / 37 = X
500/37 = X
13.5 = X
Thus, it is determined that the totality of pens is 100%, and through a cross multiplication the percentage of the 5 black pens with respect to the total of pens is obtained.
Therefore, the probability of getting a black pen from the bag is 13.5%.
Answer:
20.48 is the radius of sphere
Step-by-step explanation:
V=(4
/3)πr3
Using the formula
r=(3V
/4π)⅓
Solving for "r"
r=(3V
4π)⅓=(3·36000
/4·π)⅓≈20.48352
Answer:
candles = $400
matches = $20
Step-by-step explanation:
Let cost of candles = $c
Let cost of matches = $m
c = 20 m (20 times m)
c + m = 420
20m + m = 420
21 m = 420
m = 20
c = 20 (20) = 400
Answer:
0, -1, -3
Step-by-step explanation:
f(x) = y = height of the line plotted
if you treat the x axis as the "ground" or "floor"....you're looking for the point when the graph "hits" the "floor", meaning zero height.
