Answer:
The y-intercept is -21. The x-intercept is -10.5 or .
(0, -21) and (-10.5, 0)
Step-by-step explanation:
To find the y-intercept, you would plug in 0 for x.
y = -2x - 21
y = -2(0) - 21
y = 0 - 21
y = -21
The y-intercept is -21.
To find the x-intercept, you would plug in 0 for y.
y = -2x - 21
0 = -2x - 21
2x = -21
x = -21/2
x = -10.5 or
The x-intercept is -10.5 or .
Given:
Results of a spinner shown in the table.
To find:
The experimental probability of the spinner landing on a 1 or 7.
Solution:
From the given table it is clear that,
Spinner landing on 1 = 12 times
Spinner landing on 7 = 9 times
Spinner landing on 1 or 7 = 12+9 = 21 times
Total number of times spinner landed = 12+35+72+29+40+18+9+65+42 = 322 times
Now, the experimental probability of the spinner landing on a 1 or 7 is
Therefore, the correct option is A.
