A linear equation in two variables describes a relationship in which the value of one of the variables depends on the value of the other variable. In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable.
Answer:
12
Step-by-step explanation:
10 × 2 tens = 20 tens = 200
1 SD away from mean is 68% of data.
2 SD away from mean is 95% of data.
3 SD away from mean is 99.7% of data.
1 SD away:
190+30=220
2 SD away:
220+30=250
This shows we are on the outer 5 percent of the normal distribution.
Since you said "more", that means we only look at the right side of your 5%, which is only 2.5%
answer is D, 2.5%
