A math recap workshop is provided to the first year students entering a city college. To evaluate the workshop effectiveness, a study is conducted as following: 20 students with similar math backgrounds are randomly selected for the study. Of the 20 students, 10 of them are selected to attend the workshop and the other 10 do not attend the workshop. After the workshop has taken place a test is given to all 20 students. What is the appropriate inference test to use in this situation

Answers

Answer 1

Answer:

Independent sample t test

Step-by-step explanation:

The Independent sample t test could be explained as a statistical test carried out in other to establish or examine if significant difference exists between two independent samples. That is the outcome of the samples do not depend on one another. Using the scenario described above, the difference between the same variable is measured for two different groups which is the ideal set up for an independent sample t test. The difference between test score for two independent samples (those who attended the workshop and those who did not) is being compared.

Guys please help do I multiply or divid & which number will I be diving w or multiply

Answers

Answer:

1. a) $24, b) $36, c) $48

2. a) $18, b) $27, c) $36

3. a) $1.64, b) $2.46, c) $3.28

5. a) $30, b) $50, c) $70

6. a) $4.05, b) $6.75, c) $10.80

7. a) $14.85, b) $24.75, c) $39.60

Explanations:

Whatever we multiply the item by, we multiply the cost by. If we double the number of socks, we double the price. If we triple the number of socks, we triple the price.

1. a) 3 costs $12, and 3 x 2 = 6, so we do the same to the price: $12 x 2 = $24

b) 3 times 3 is 9, so 3 x 12 gives you that cost, $36

c) 3 x 4 = 12, so 12 x 4 = $48

2. a) 3 pairs is $9, and we need 6 pairs. 3 x 2 = 6, so we also multiply the price x 2 = $18

b) 3 x 3 = 9 pairs, multiply the cost times 3 as well. 9 x 3 = $27

c) 3 x 4 = 12, multiply the cost x 4. 9 x 4 = 36

3. 4 apples cost $0.82

a) 4 x 2 = 8 apples, $0.82 x 2 = $1.64

b) 4 x 3 = 12 apples, $0.82 x 3 = $2.46

c) 4 x 4 = 16 apples, $0.82 x 4 = $3.28

Which symbol correctly compares the two angles? pi 3 \ 60^

Answers

Answer: =

Step-by-step explanation: just took the test

We will see that both angles are actually the same one (but in different units) so the symbol that we need to use is the equal symbol.

Which symbol correctly compares the two angles?

Here we have two angles, one in degrees and  the other in radians, we want to compare them. To do it, we will need to write both of the angles in the same units.

The angles are:

pi/3 rads

60°

First, remember that:

pi rads = 180°

1 rad = (180°/pi)

With this, we can change the units of the first angle to get:

pi/3 rads = pi/3*(180°/pi) = 180°/3 = 60°

So both angles are actually the same angle, then the symbol that correctly compares them is the equal symbol.

pi/3 rads = 60°

You select 13 cards without replacement from a standard deck of 52 cards.

To Find :

The probability that you get 4 aces.

Solution :

Since, it is given that we need to select cards without replacement.

Probability of getting 4 aces is :

[tex]P = \dfrac{1}{52}\times \dfrac{1}{51}\times \dfrac{1}{50} \times \dfrac{1}{49}\times 4!\\\\P = 3.693 \times 10^{-6}[/tex]

|x-4| if x>4
can you please help me

Answers

Answer:  x - 4  without the absolute value bars surrounding it

=================================================

Explanation:

If x is larger than 4, then x-4 is positive. For example, if x = 5, then

x-4 = 5-4 = 1

So for cases when x > 4, the |x-4| and x-4 are the same identical expression. Try out more values of x to compare the two outputs. I recommend making a table with 3 columns. You'll have x in column 1, then |x-4| in column 2, and x-4 in column 3. You should find that the outputs for columns 2 and 3 are identical when x is larger than 4.

It's only when x < 4 is when |x-4| and x-4 differ. Instead we would say |x-4| = -(x-4). But we aren't focused on this case.

In short, when x > 4, we simply drop the absolute value bars to get the answer  x - 4
