Answer:

  6

Step-by-step explanation:

Because you are familiar with your times tables, you know that ...

  30 = 6·5

  42 = 6·7

The greatest common factor is 6.

Answer:

4

Step-by-step explanation:

30 + 20 + 13 = 63, + fractions = 64. But you have to divide to get to pounds. So 64 / 16 = 4

Answer:

[tex]x=3\\y=-10[/tex]

Step-by-step explanation:

[tex]13x=-21-6y\\-8x=36+6y[/tex]

Let's take one of the equations and solve for x. I'll take the first one.

[tex]13x=-21-6y[/tex]

Divide by 13.

[tex]x=\frac{-21-6y}{13}[/tex]

Now replace x in the second equation.

[tex]-8x=36+6y\\-8(\frac{-21-6y}{13} )=36+6y[/tex]

Distribute -8

[tex]\frac{168+48y}{13}=36+6y[/tex]

Break down the fraction.

[tex]\frac{168}{13}+\frac{48}{13}y=36+6y[/tex]

Subtract [tex]\frac{168}{13}[/tex]

[tex]\frac{48}{13}y=36+6y-\frac{168}{13}[/tex]

Subtract 6y

[tex]\frac{48}{13}y-6y=36-\frac{168}{13}[/tex]

Combine like terms;

[tex]\frac{48-13*6}{13}y=\frac{36*13-168}{13}[/tex]

Solve;

[tex]\frac{48-78}{13}y=\frac{468-168}{13}[/tex]

Keep solving;

[tex]\frac{-30}{13}y=\frac{300}{13}[/tex]

Multiply by the negative reciprocal of the fraction next to y.

[tex](-\frac{13}{30} )\frac{-30}{13}y=\frac{300}{13}(-\frac{13}{30} )[/tex]

On the right side; 13 and 13 become 1. 300/30 = 30/3 = 10

[tex]y=-10[/tex]

After having found y, replace it in any of the equations to find x.

[tex]13x=-21-6y\\13x=-21-6(-10)\\13x=-21+60\\13x=39\\x=\frac{39}{13}\\ x=3[/tex]

Answer:

x=3

y=-10

Step-by-step explanation:

13x=-21-6y...............(1)

-8x=36+6y................(11)

Add (11) to (1)

5x=15-6y+6y

5x=15

Divide both sides by 5

5x/5=15/5

x=3

Substitute x=3 in 13x=-21-6y

13(3)=-21-6y

39=-21-6y

Collect like terms

39+21=-6y

60=-6y

Divide both sides by -6

60/-6=-6y/-6

-10=y

y=-10

Answer:D

Step-by-step explanation:

(4/5)^0

(4^0)/(5^0)=1/1=1

Answer:

a) Sample Space = {(1,blue), (1, green), (1, yellow), (2,blue), (2, green),                (2, yellow), (3,blue), (3, green), (3, yellow), (4,blue), (4, green), (4, yellow)}

b) 4 outcomes involve choosing blue marble.

Step-by-step explanation:

a) FOR SAMPLE SPACE:

No. of options for choosing card = 4

No. of options for choosing marble = 3

No. of options for choosing a card and a marble = (3)(4) = 12

Therefore,

Sample Space = {(1,blue), (1, green), (1, yellow), (2,blue), (2, green),              (2, yellow), (3,blue), (3, green), (3, yellow), (4,blue), (4, green), (4, yellow)}

b) CHOOSING BLUE MARBLE:

It is evident from the sample space that, there are only 4 outcomes, which involve choosing a blue marble.

Those 4 outcomes are as follows:

(1, blue), (2, blue), (3, blue), (4, blue)

Answer:

12

Step-by-step explanation:

Answer:

a

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

Firstly, [tex]x^{-y} = \frac{1}{x^y}[/tex], so in this case, you multiply [tex](6^{-8})^4[/tex], which equals [tex]6^{-32}[/tex]. Then, plug it into [tex]x^{-y} = \frac{1}{x^y}[/tex] and you get

[tex]6^{-32} = \frac{1}{6^{32}}[/tex], so it's [tex]\boxed{A.}[/tex]

Answer: about 450.52

Use Pythagorean Theorem to find the diameter of the circle. Divide the diameter by 2 to find the radius, and solve for the area of the circle (πr^2). Then, solve for the area of the triangle (bh/2). Subtract the area of the triangle from the area of the circle.

Answer:

Step-by-step explanation:

It costs $7 for 1 baseball and Mrs.Weeks is buying 36 baseballs, that would be: $7 X 36 = $252

It costs $5 for 1 softball and Mrs.Weeks is buying 24 softballs that would be:

$5 X 24 = $120

$252 + $120 = $372 for the baseballs and softballs

Mrs.Weeks gives the cashier four $100 bills that is $400 dollars.

so $400 - $372 = $28 (Mrs.Weeks change)

Answer:

Yes, Sam is correct and there is no need to fix his idea.

Step-by-step explanation:

Linear Regression model is one of the Important model that is been used in statistics especially in statistics which actively involved data analysis of dependent variable and an independent variable. Between these two that is dependent variable and an independent variable, the application of Linear Regression model is used in showing the relationships between the two variables.

Just like Sam said in the question above, '' “Linear regression model is a tool to predict the relationship between the dependent variable, and independent variable...'', that is what linear regression is used for.

Answer:

1. Statement: ∠RVS ≅ ∠SVT

2. Statement: m∠RVS + m∠SVT = 180°

3. Statement: m∠RVS + m∠RVS = 180°

4. Statement: m∠RVS = 90°

5. Statement: Line RT ⊥ Line SU

1. Reason: Given

2. Reason: Angles forming a linear pair sum of 180°

3. Reason: Substitution

4. Reason: Algebra

5. Reason: Defintion of perpendicular lines

Step-by-step explanation:

First, write the given (line 1).

Next, use the fact that angles forming a linear pair sum to 180° to show m∠RVS + m∠SVT = 180° (line 2).

Next, substitute m∠RVS for m∠SVT in m∠RVS + m∠SVT=180° (line 3).

Next, use algebra to show m∠RVS = 90° (line 4).

Finally, use the definition of perpendicular lines to prove that Line RT ⊥ Line SU (line 5).

Answer:

a = 2

not continuous

Step-by-step explanation:

In order for f(x) to have a limit at 0, f(0) from the left must equal f(0) from the right.

f(0⁺) = f(0⁻)

-2 + a = a sin(0)

-2 + a = 0

a = 2

If f(x) is continuous at x = 0, f'(0) from the left must equal f'(0) from the right.

f(x) = 0 for x > 0, so f'(x) = 0 for x > 0.

f(x) = 2 sin x for x < 0, so f'(x) = 2 cos x for x < 0.

f'(0⁺) = f'(0⁻)

0 = 2 cos 0

0 = 2

f(x) is not continuous at x = 0.

a = 2

Answer:

1320 feet

Step-by-step explanation:

All we have to do is multiply the rate of change of altitude by the time it took the altitude to change.

The altitude of an airplane is decreasing at a rate of 44 feet per second. After 30 seconds, the change is altitude is:

44 * 30 = 1320 feet

The altitude of the airplane has changed by 1320 feet.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Developing a frequency distribution of the ungrouped data simply means creating a structure (table) for the data. It is a method of converting an ungrouped data into a grouped data for proper analysis of the data.

The table will contain the values, their frequency (this means the number of times individual values occurs based on the classes) and the tally.

Check the attachment for the table.

Given the ungrouped data 2 5 10 12 4 4 5 17 11 8 9 8 12 21 6 8 7 13 18 3. The total number of data collected is 20. From the frequency distribution table, it can be seen that the total frequency is 20 which shows that all the values have been catered for.

Answer:

it will be 95%

hope that helps

Answer:

95 percent

Step-by-step explanation:

Since 20 is 1/5 of 100, one number is equivalent to 5 percent.

Multiply 5 by 19.

You will get your percentage.

Answer:

Step-by-step explanation:

It is assumed the first winner is part of the second drawing as well

There are 4 people and two prizes

The probability of each person to win is 1/4

The first winner has 1/2 probability to get a mug

The second winner, if it is Jack, gets either prize

The combined probability is:

Answer:

The probability is 37.5%

Step-by-step explanation:

There are eight total outcomes, but we only need to focus on three. Ang winning a mug and Jack winning either a t-shirt or a mug, that makes three. Write that as a fraction: 3/8, and then divide. 3 divided by 8 gives us 0.375. But we need a percent so multiply that by 100, that now gives us 37.5.

So, the probability that either Ang wins and is given a mug, or Jack wins is 37.5%. If it makes you feel more confident in this, I put the same exact answer for my assessment and I got it correct.
