Answer:
x=10
y=-2
(10,-2)
Step-by-step explanation:
If X=10, we can put 10 in for x in the equation.
30 + 5y = 20
Next, we need to solve to find y.
We will get y on its own so we subtract 30 from 20 to get
5y=-10
We then know that 5 goes into -10 -2 times.
y=-2
Answer:
a. The empirical rule.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
So the correct answer is:
a. The empirical rule.
