At the beginning of the school year, Jamie had $500 in her savings account. She wants to have at least $200 left in the account at the end of the school year. Each week, she withdraws $30 for spending money. To determine how many weeks she can spend $30, Jamie wrote and solved this inequality.
500 − 30x ≥ 200
−500 −500
−30x ≥ −300
x ≥ 10
Review Jamie’s work. What was her error?
Answers
Her error was that she misplaced the numbers
-30x ≥ -300
its supose
to be -30x ≥ 200
Answer:
Jamie should have reversed the inequality when using the division property of inequality.

A couple's anniversary dinner bill was $126.50. They tipped their waiter 20% of the bill. What was the total bill including tip?
Answers
Answer:
$151.80 was the total bill including tip.
Step-by-step explanation:
$126.50 x 20% = $25.30
$126.50 + $25.30 = $151.80
$151.80
$126.5•1.2=$151.8
8. You sold 1000 shares of Ibex for $10.50 per share. Your broker charges you a
commission of $3.25 per thousand dollars of stock bought or sold. How much
money will be credited to your account when you sell? (Remember, commissions
are subtracted out of your transaction.)
Answers
Answer:
Amount credit in account = $10,465.875
Step-by-step explanation:
Given:
Number of shares = 1,000
Selling price of each share = $10.50
Broker charges = $3.25 per 1,000 dollar
Find:
Amount credit in account
Computation:
Total sales value = Number of shares x Selling price of each share
Total sales value = 1,000 x 10.50
Total sales value = $10,500
Total broker charges = 10,500 [3.25/1000]
Total broker charges = $34.125
Amount credit in account = Total sales value - Total broker charges
Amount credit in account = 10,500 - 34.125
Amount credit in account = $10,465.875

The Center for the Study of Violence wants to determine whether a conflict-resolution program in a particular high school alters aggressive behavior among its students. For 5 students, aggression was measured both before and after they participated in the conflict-resolution course. Their scores were the following (higher scores indicate greater aggressiveness).
Before Participating After Participating
10 8
3 3

8 5
8 7
Required:
a. What is the test statistic
b. What are the degrees of freedom
c. Do you reject the null (at alpha = 0.05)
d. What do your results indicate
Answers
Answer:
A.) 3.096 ; b.) 4 ; C). We reject the Null
D.) There is significant evidence to support the claim that conflict resolution program reduces level of aggression in STUDENTS.
Step-by-step explanation:
This is a paired test:
Given the data:
Before (x) __ After (y) __ difference (x - y)
10 ______ 8 ______ 2
3 _______ 3 ______ 0
4 _______ 1 _______3
8 _______ 5 ______ 3

dbar = Σd / n ; n = sample size
dbar = 9 / 5 = 1.8
From calculator :
Standard deviation of d, Sd = 1.30
Test statistic = dbar ÷ (Sd / √n)
Test statistic = 1.8 ÷0.5813776
Test statistic = 3.096
Pvalue from test statistic :
df = n - 1 = 5 - 1 = 4
Pvalue, 0.05, 4 = 0.018
Since Pvalue < α ; We reject the Null
We conclude that, there is significant evidence to support the claim that conflict resolution program reduces level of aggression in students.

Triangle UVW has a perimeter of 11.5 units. Solve for y.
Answers
Answer:
The answer for y is 4 units
Step-by-step explanation:
The obvious question to ask in this situation is, “how many miles does Joseph travel on Mondays”? To compute, we each distance: 3 + 6 + 6 = 15.
Joseph travels 15 miles on Mondays.
Another way to work with this situation is to draw a shape that represents Joseph’s travel route and is labeled with the distance from one spot to another.
Notice that the shape made by Joseph’s route is that of a closed geometric figure with three sides (a triangle) (see figure 2). What we can ask about this shape is, “what is the perimeter of the triangle”?
Perimeter means “distance around a closed figure or shape” and to compute we add each length: 3 + 6 + 6 = 15
Our conclusion is the same as above: Joseph travels 15 miles on Mondays.
However, what we did was model the situation with a geometric shape and then apply a specific geometric concept (perimeter) to computer how far Joseph traveled.

4 units
