Answer:
distance= 9 units to the nearest
Step-by-step explanation:
using the formula
√(∆x)^2+(∆y)^2
√73
= 8.5
= 9 units
Answer:
n = -4/7
Step-by-step explanation:
this is an easy question, you should learn how to do this with no help because you get into more complex questions with more variables.

Answer:
78.46
Step-by-step explanation:
Given that
Pop. Standard deviation = 1.61
Sample standard deviation = 2.15
Sample mean = 7.47
Sample size = 45
Recall that
Test stat for chi square
= (n - 1) (sample standard dev/pop standard dev)^2
= 45 - 1 (2.15/1.61)^2
= 44(1.3354)^2
= 44 × 1.78329
= 78.46
