Factor the expression using the GCF.
42 – 12 =

Answers

The factors of the expression 42 - 12 are 2(21 - 6), 3(14 - 4), 6(7 - 2).

What are GCF and distributive property?

The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.

We also know that distributive property states a(b + c) = ab + ac.

Given, We have to factor 42 - 12.

Now, Factors of 12 are 1, 2, 3, 4, 6 and 12.

Factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.

Common factors of 12 and 42 are 2, 3 and 6.

So, 42 - 12.

= 2(21 - 6).

= 3(14 - 4).

= 6(7 - 2).

https://brainly.com/question/11444998

#SPJ2

The factored form of the expression 42 - 12 using the GCF is 6(7 - 2).

To factor the expression 42 - 12 using the greatest common factor (GCF), we need to find the largest number that divides both 42 and 12.

First, let's find the prime factorization of both numbers:

42 = 2 x 3 x 7

12 = 2 x 2 x 3

Now, let's find the common factors:

The common factors are 2 and 3.

Next, let's determine the GCF by multiplying the common factors:

GCF = 2 x 3 = 6

Finally, we can factor out the GCF from the expression:

42 - 12 = 6 x (7 - 2)

Therefore, the factored form of the expression 42 - 12 using the GCF is 6(7 - 2).

Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.

Decimal number system describes the base 10 number system.

Here we have to find the difference of 1 - 0.4308.

Here, the number is 0.4308, which is a decimal number.

Write 1 as the decimal number as 1.0000

Subtracting as done as usual whole numbers, we get,

1.0000 - 0.4308 = 0.5692

Answers

Answer:

D

Step-by-step explanation:

Proportional relationships come in the form

[tex]y=kx[/tex]

and [tex]k[/tex] is the constant of proportionality. By comparing the general case [tex]y=kx[/tex] and your specific case [tex]y=12x[/tex], you can see that in your case [tex]k=12[/tex].

In the equation y = 12x the constant of proportionality is D. 12.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Let y = kx.

k = y/x.

Given, y = 12x.

12 = y/x.

Answers

Answer:

[tex]3.4x\le 100[/tex]

Step-by-step explanation:

Given that,

Michael is cutting a 100-yard ribbon into pieces 3.4 yards long.

Michael says that an inequality that represents his project is 3.4x 100.

Let Michael cuts the ribbon in x no of variables. It is given as :

3.4x is the total length of all the pieces together

i.e.

3.4x is less than or equal to 100.

The required equation that represents the given scanario is :

[tex]3.4x\le 100[/tex]

Answer:

Step-by-step explanation:

Sample Response: The variable, x, is the number of pieces of ribbon Michael cuts. Since each piece is 3.4 yards long, 3.4x is the total length of all the pieces together. This total length cannot be more than the 100 yards of ribbon he has, so 3.4x must be less than or equal to 100.

McAllister et al. (2012) compared varsity football and hockey players with varsity athletes from noncontact sports to determine whether exposure to head impacts during one season have an effect on cognitive performance. In the study, tests of new learning performance were significantly poorer for the contact sport athletes compared to the noncontact sport athletes. The following table presents data similar to the results obtained in the study.
Noncontact Athletes:
10, 8, 7, 9, 13, 7, 6, 12
Contact Athletes:
7, 4, 9, 3, 7, 6, 10, 2
a. Are the test scores significantly lower for the contact sport athletes than for the noncontact athletes? Use a one-tailed test with \alpha=.05

b. Compute the value of (percentage of variance accounted for) for these data.
r^2= a. 0.123, b. 0.239, c. 0.138, d. 0.264

Answers

Answer:

[tex]t _{critical} = 1.760[/tex]

t = 2.2450

d. 0.264

Step-by-step explanation:

The null hypothesis is:

[tex]H_o: \mu_1 - \mu_2 = 0[/tex]

Alternative hypothesis;

[tex]H_a : \mu_1 - \mu_2 > 0\\[/tex]

The pooled variance t-Test would have been determined if the population variance are the same.

[tex]S_p^2 = \dfrac{(n_1-1)S_1^2+(n_2-1)S^2_2}{(n_1-1)+(n_2-1)}[/tex]

[tex]S_p^2 = \dfrac{(8-1)2.507^2+(8-1)2.8282^2}{(8-1)+(8-1)}[/tex]

[tex]S_p^2 = 7.14[/tex]

The t-test statistics can be computed as:

[tex]t= \dfrac{(x_1-x_2)-(\mu_1 - \mu_2)}{\sqrt{Sp^2 ( \dfrac{1}{n} +\dfrac{1}{n_2})}}[/tex]

[tex]t= \dfrac{(9-6)-0}{\sqrt{7.14 ( \dfrac{1}{8} +\dfrac{1}{8})}}[/tex]

[tex]t= \dfrac{3}{1.336}[/tex]

t = 2.2450

Degree of freedom [tex]df = (n_1 -1) + ( n_2 +1 )[/tex]

df = (8-1)+(8-1)

df = 7 + 7

df = 14

At df = 14 and ∝ = 0.05;

[tex]t _{critical} = 1.760[/tex]

Decision Rule: To reject the null hypothesis if the t-test is greater than the critical value.

Conclusion: We reject [tex]H_o[/tex] and there is sufficient evidence to conclude that the test scores for contact address s less than Noncontact athletes.

To calculate r²

The percentage of the variance is;

[tex]r^2 = \dfrac{t^2}{t^2 + df}[/tex]

[tex]r^2 = \dfrac{2.2450^2}{2.2450^2 + 14}[/tex]

[tex]r^2 = \dfrac{5.040025}{5.040025+ 14}[/tex]

[tex]r^2 = 0.2647[/tex]
