Answer:
Rounded to the nearest tenth they are -14.5 and 12.5
Step-by-step explanation:
The zeros of a function are the x-intercepts or roots where the function crosses the x-axis. To find them, graph the function x^2 +2x-180 and zoom in on the x-axis.

Answer:
The probability that both balls are red is 5.81%, that one is red and one black is 38.36%, and that both are black 55.81%.
Step-by-step explanation:
Given that a box contains 44 table tennis balls having the same shape and size, and among them 33 are black and remaining balls are red, if two balls are drawn randomly one after another without replacement, to show the probability of all possible outcomes the following calculations must be done:
Red + red:
11/44 + 10/43 = 0.25 x 0.2325 = 0.0581
Red + black:
11/44 + 33/43 = 0.25 x 0.7674 = 0.1918
Black + red:
33/44 + 11/43 = 0.75 x 0.2558 = 0.1918
Black + black:
33/44 + 32/43 = 0.75 x 0.7441 = 0.5581
19.18 x 2 = 38.36
Therefore, the probability that both balls are red is 5.81%, that one is red and one black is 38.36%, and that both are black 55.81%.
Hello. There was no figure to look at so I plotted all of these points for you. Which one looks like the figure to you? That will be your answer.
Remember, you plot the first number first, which will be along the X axis on a graph. Thats the line that runs right to left.
Then you plot the second number, which will be along the Y axis on a graph.
Thats the line that runs up and down.
If you go down or to the left, you will have a negative point. If you go up or to the right you will have a positive point.
Answer:
A
Step-by-step explanation:
86.50 times 20
24.50 times 20
1,730-490= 1,240
1,240 divvied by 0.25 = 310
