Answer:
D
Step-by-step explanation:
There is no data set so there is no data to find the mean of.
Answer:
105km
Step-by-step explanation:
1/7=15/x
So x=7*15
x=105
(-2,5)(9,-6)
slope(m) = (-6-5) / (9 - (-2) = -11/11 = -1
y = mx + b
slope(m) = -1
(-2,5)...x = -2 and y = 5
now we sub and solve for b, the y int
5 = -1(-2) + b
5 = 2 + b
5 - 2 = b
3 = b
so ur equation in slope intercept form is : y = -x + 3

Answer:
There are 151,200 possible license plates.
Step-by-step explanation:
The order in which the digits are positioned is important(for example, 012345 is a different plate than 102345). No repeat digits are allowed, which means that we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
![P_{(n,x)} = \frac{n!}{(n-x)!}](https://tex.z-dn.net/?f=P_%7B%28n%2Cx%29%7D%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-x%29%21%7D)
In this question:
There are 10 possible digits(from 0 to 9).
The plate has 6 slots.
So
![P_{(10,6)} = \frac{10!}{(10-6)!} = 151200](https://tex.z-dn.net/?f=P_%7B%2810%2C6%29%7D%20%3D%20%5Cfrac%7B10%21%7D%7B%2810-6%29%21%7D%20%3D%20151200)
There are 151,200 possible license plates.
