Mr. Newcomb brought a coffee for himself for $2.38 and for Ms. Latona for $3.65 at Dunkin Donuts. He paid with a $20 bill. How much change did he get?

Answers

Answer:

$13.97

Step-by-step explanation:

First, find how much the cost was for the two coffees:

2.38 + 3.65

= 6.03

Find how much change he got by subtracting this from 20:

20 - 6.03

= 13.97

So, he got $13.97 in change

Answer:

Solution :-

At first the total money spent by Mr. Newcomb = $ 2.38 + $3.65

=> 6.03

Now

According to the question

Change she get = 20 - 6.03

= 13.97

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

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

8 _______ 7 ______ 1

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.
