Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.
First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.
141 + 161 = 302
Now, that we know how much Jack saves per month.
Then, we have to find out how many months are in 2 years.
We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.
12 x 2 = 24
Therefore, there are 24 months in two years.
Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.
24 x 302 = 7,248
Thus, Jack will save approximately $7,248 in 2 years.

Answer:
<h2>
$5.03</h2>
Step-by-step explanation:
Given data
Sample Mean (M): $48.77
Sample Size (n): 20
Standard Deviation (σ) : $17.58
Confidence Level: 80%
we know that z*-Values for 80% Confidence Levels is 1.28
the expression for margin of error is given bellow\
MOE= z*σ/√n
We can now substitute into the expression and solve for the MOE as
MOE= 1.28*17.58/√20
MOE= 22.502/4.47
MOE= 22.502/4.47
MOE= 5.03
The margin of error for a 80 % confidence interval is $5.03

Because you are using the format y = mx +c the c value is the y offset.
in this equation the equation can be rewritten as y = 1x -3
Thus the y intercept, the y offset, must be -3.
Hope this helps! :)
