Answer:
T is at (13,-6)
Step-by-step explanation:
x-coordinate of T: from -9 to 2, there's 11 units, so you add 11 to 2 to find the x-coordinate of T, which is 13.
y-coordinate of T: from 4 to -1 there's -5 units, so you subtract 5 from -1 to find the y-coordinate of T, which is -6.
Answer:−1(2n + 1)

Answer:
The only option (0,0) is possible.
Step-by-step explanation:
Here in options four ordered pairs are given and they are (-3,-18), (-0.5,-3), (0,0) and (0.5,3).
Here, the x-values represent the number of books and the y-value represents the total weight of the books, in ounces.
Now, x must be 0 or a positive integer as it is the number of books.
Hence, the only option (0,0) is possible which means that the weight of zero books is zero. (Answer)
Answer:
68% of races will his finishing time be between 79.5 and 82.5 seconds
Step-by-step explanation:
Mean time = 81 seconds
Standard deviation = 1.5 seconds
According to the empirical rule : 68%, 95%, 99% lies within 1, 2, and 3 standard deviations of the mean respectively.
Hence, for a finishing time between : 79.5 and 82.5
79.5 = 81 - 1.5 (1 standard deviation to the left of the mean)
82.5 = 81 + 1.5 (1 standard deviation to the right of the mean)
Hence,
79.5 and 82.5 lies within 1 standard deviation from the mean and it is Hence has a percentage of 68%
