Roughly 95% of the data lies within 2 standard deviations of the mean.
So (100% - 95%)/2 = 2.5% of the data lies within each tail.
This means roughly 2.5% of the data is in the left hand tail.
Answer:
(A)
Slope for f(x) is 3
Slope for g(x) is 4
(B)
So, y-intercept for f(x) is greater
Step-by-step explanation:
(A)
Slope of f(x):
we can select any two points
(-1,-6)
so, x1=-1 and y1=-6
(0,-3)
so, x2=0 , y2=-3
now, we can use slope formula

now, we can plug values


Slope of g(x):
we can compare with
y=mx+b

so, m=4
so, slope is 4
(B)
For f(x):
we can select point as
x=0 , y=-3
so, y-intercept is -3
For g(x):

we can compare with
y=mx+b
where
b is y-intercept
we get
b=-5
we know that -3 is greater than -5
So, y-intercept for f(x) is greater
Answer:
$114.08
Step-by-step explanation:
subtract 5.50 from 98.00 and get 92.05
98.00
- 5.50
_______________
92.5
then add 92.05 and 22.75 to get 114.08
Answer:
$5.46
Step-by-step explanation:
Find out how much she had to pay by multiplying the amount she got by the cost and adding the two totals together.
4*2.49=9.96
2*2.29=4.58
4.58+9.96=14.54
Subtract to find change
20-14.54=5.46
