Answer:

b. numerical indicator of the strength and direction of a relationship between two factors.

Step-by-step explanation:

Correlation coefficient:

The correlation coefficient between two variables is how closely they are related.

For example, in vectors with high correlation coefficient, they are similar, while with low coefficient, they are significantly different. So the correct answer is given by option b.

Answer:

approximately Normal with mean 0.35

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

A researcher reports that 80% of high school seniors would pass a driving test, but only 45% of high school freshmen would pass the same driving test.

This means that [tex]p_1 = 0.8, p_2 = 0.45[/tex]

Subtraction of Variable 1 by Variable 2:

By the Central Limit Theorem, the shape will be approximately normal.

The mean is the subtraction of the means of each proportion. So

[tex]p = p_1 - p_2 = 0.8 - 0.45 = 0.35[/tex]

So the correct answer is given by:

approximately Normal with mean 0.35

Answer:

x=7/5

Step-by-step explanation:

12x+3x=15+6

15x=21

x=7/5

Answer:

X= [tex]\frac{7}{5}[/tex]

Step-by-step explanation:

Ok...

Get ready to see Alot more numbers

1. Rearrange terms.

12x-15=6-3x

12x-15=-3x+6

2. Add 15 to both sides.

12−15=−3+6

12−15+15=−3+6+15

3. Simplify

If you add the numbers you will get:

12x=-3x+21

4. Add 3x to both sides of the equation.

12x=-3x+21

12x+3x=-3x+21+3x

5. Simplify

If you combine the like terms you will get,

15x=21

6. Divide both sides of the equation by the same term.

15x=21

[tex]\frac{15x}{15}[/tex] = [tex]\frac{21}{15}[/tex]

7. Simplify

If you cancel terms that are in both of the numerator and denominator, then divide the numbers you will get:

x= [tex]\frac{7}{5}[/tex]

Answer:

  ∠2 = 19°

Step-by-step explanation:

Angles that are equal to 161° are vertical and corresponding angles: 1, 4, 5.

Angles that are equal to the supplement of 161° are the remaining angles: 2, 3, 6, 7.

Angle 2 is the supplement of 161°:

  ∠2 = 180° -161°

  ∠2 = 19°

Answer:

|–2| |5| |–8| |11| |–12|

Answer:

|-2|,|5|,|-8|,|11|,|-12|

Step-by-step explanation:

This is the order because |-2| in absolute value is positive 2 and |11| in absolute value is still positive because you don't change the sign unless the ll was negative in absolute value.

Answer:

1/10

Step-by-step explanation:

Divide 3/10 by 3. Remember to "keep, flip, change".

3/10 ÷ 3/1

3/10 × 1/3

Multiply across: 3/10 × 1/3 = 3/30

Simplify: 3/30 = 1/10

Answer:

Working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.

Step-by-step explanation:

Given that Ted can change an advertisement on a billboard in 5 hours, while Marie can do the same job in 2 hours, to determine how long it would take them if they worked together the following calculation must be performed:

Ted 1/5 in 1 hour

Marie 1/2 in 1 hour

1/5 + 1/2 = X

5X + 2X = 10

7X = 10

X = 10/7

X = 1 3/7

60/7 x 3 = 25.71

60 x 0.71 = 42.6

So, working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.

Answer:

1: 1.5 Jam Went Into Each Cup

2: 125 pages

Step-by-step explanation:

1

In order to find our answer we first have to divide 6/4, we then get 1.5 jam, finally we check our answer 1.5 x 4 = 6, Thus that is our answer

2

If Jada has read 3/5 of a book, and that equals 75, then we divide 75 by 3 giving us 25, then in order to find the answer we have to multiply 25 by 5, thus 125 is our answer

Charlie will receive the ring in 21 months.

It is a method of buying something in which a person can make a downpayment to buy something at a store and the store holds the item on their behalf until the last payment is done after which they gain possession of it.

Charlie has put in a ring on layaway. This means that he will only receive the ring in 21 months after he has finished paying all the installments. He will not gain possession of the ring right away after making the downpayment of $85.

Thus, we have found that Charlie will receive the ring in 21 months. The correct answer is option A.
