Answer:

The answer is C

Step-by-step explanation:

The x-coordinate is -4 and the y is 1 so it matches.

Answer:

m = 1/6

Step-by-step explanation:

x1 = 1

x2 = -5

y1 = -3

y2 = -4

to find slope

m = (y2 - y1) / (x2 - x1)

m = [(-4) - (-3)] / [(-5) - (1)]

m = (-1) / (-6)

m = 1/6

Answer:

4  sq 8

Step-by-step explanation:

The expression that could represent the length of one side of the square is; [tex]4x^2y^4[/tex].

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol it can also be used to indicate the logical syntax's order of operations and other features.

Given that;

The area of the square A  = [tex]16x^4y^8[/tex]

Consider that a is the side length of the square

The area of the square is given by;

[tex]\Rightarrow A=(\text{side length})^2[/tex]

So, we can write the expression as;

[tex]\Rightarrow a^2=16x^4y^8\\\\\Rightarrow a=4x^2y^4[/tex]

Hence, the length of each side is 4x^2y^4

The solution for equations y = −4x + 3 and 4x − 2y = 6 is x = 1 and y = -1, the graph is also attached below.

A formula known as an equation uses the equals sign to denote the equality of two expressions. In other terms, it is a mathematical statement stating that "this is equivalent to that." It appears to be a mathematical expression on the left, an equal sign in the center, and a mathematical expression on the right.

Given:

y = −4x + 3

4x − 2y = 6

Solve the above equation by elimination method,

Subtract equation 2 from equation 1,

y = -1 and

Answer:

y = 2

Step-by-step explanation:

Given

y + 7 = 9 ( subtract 7 from both sides )

y = 2

Simplifying

y + 7 = 9

Reorder the terms:

7 + y = 9

Solving

7 + y = 9

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + y = 9 + -7

Combine like terms: 7 + -7 = 0

0 + y = 9 + -7

y = 9 + -7

Combine like terms: 9 + -7 = 2

y = 2

Simplifying

y = 2

Answer:

b. The standard deviation for class 1 is approximately 18.81415

The standard deviation for class 2 is approximately 16.1527

The standard deviation for class 3 is approximately 12.705

c. The mean of the data indicates that the average scores of Class 1 and Class 2 are equal and less than the average score of Class 3

The standard deviation indicates that the data in Class 1 varies more than the data in Class 2, and also, that the data of Class 2 varies more than the data of Class 3.

Step-by-step explanation:

b. The mean and the standard deviation can be calculated using Microsoft Excel with the values presented here as results as follows;

The standard deviation, σ is given by the formula [tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}}[/tex], while the formula mean, μ is [tex]\mu = \dfrac{\Sigma x}{N}[/tex]

Where;

N = The number of terms = 12

∑x = 946 for Class 1, 953 for Class 2, 953 for Class 3

The mean for Class 1 = ∑x for Class 1/N = 946/12 = 78.8[tex]\bar 3[/tex]

The mean for Class 2 = ∑x for Class 2/N = 953/12 = 79.41[tex]\bar 6[/tex]

The mean for Class 3 = ∑x for Class 3/N = 953/12 = 79.41[tex]\bar 6[/tex]

[tex]\sum \left (x_i-\mu \right )^{2} }[/tex] for Class 1 = 4247.[tex]\bar 6[/tex]

[tex]\sum \left (x_i-\mu \right )^{2} }[/tex]/N = for Class 1 = 353.97[tex]\bar 2[/tex]

The standard deviation for class 1 σ₁, is given as follows;

[tex]\sigma_1 =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}} = \sqrt{353.97\bar 2 } \approx 18.81415[/tex]  

The standard deviation for class 1 = 18.81415

[tex]\sum \left (x_i-\mu \right )^{2} }[/tex] for Class 2 = 3130.9167

[tex]\sum \left (x_i-\mu \right )^{2} }[/tex]/N = for Class 2 = 260.90972

The standard deviation for class 2 σ₂, is given as follows;

[tex]\sigma_2 =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}} \approx \sqrt{260.90972 } \approx 16.1527[/tex]

The standard deviation for class 2 = 16.1527

[tex]\sum \left (x_i-\mu \right )^{2} }[/tex] for Class 3 ≈ 1936.917

[tex]\sum \left (x_i-\mu \right )^{2} }[/tex]/N = for Class 3 ≈ 161.4097222

The standard deviation for class 3 σ₃, is given as follows;

[tex]\sigma_3 =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{N}} \approx \sqrt{161.40972 } \approx 12.705[/tex]

The standard deviation for class 3 ≈ 12.705

c. The mean indicates that the average score for Class 1 is higher than the average score for Class 2, and that the average score for Class 2 is the same as the average score for Class 3

However, the standard deviation indicates that the variability of the scores for Class 1 is higher than the variability of the scores for Class 2, and that there is also a higher variability in the scores of Class 2 than the variability in the scores of class 3

The annual growth rate r for an investment can be found using P=Po(1+rt), where is time in years, P is the present value, and P0 is the original investment. An investment of $4000 was made in 2005 and had a value of $7500 in 2010. What was the average growth rate of the investment?

Given

Po=$4000

P=$7500

time = 2010-2005= 5 years

rate r =?

Step two

7500=4000(1+r*5)

7500=4000+20000r

7500-4000=20000r

3500=20000r

divide both sides by 20000

r=3500/20000

r=0.175

% rate= 0.175*100

%rate= 17.5

Therefore the average growth rate is 17.5%

Answer:

Matthews average speed was 62 miles per hour.

Step-by-step explanation:

We know that Matthew drove 15 1/2 miles in 1/4 of an hour. We want to know how many miles Matthew drove every hour. To solve this problem, multiply 15 1/2 by 4.

15 1/2 x 4 = 62

Therefore, Matthews average speed was 62 miles per hour.

Answer:

⇨ Choice A.

Step-by-step explanation:

We'll consider three choices and compare the answers with the given number line and points.

⟺ Choice A

This is the correct answer and here is why.

[tex]-b>0[/tex]

Solving Inequality is similar to solving equation. The difference is if the coefficient for the variable is in negative, moving to another side would swap the sign/operator of Inequality.

Thus, our new Inequality would be [tex]b<0[/tex] which is true by the number line itself.

⟺ Choice B

The reason why choice B is not correct because the point a is lesser than the point b. It's obvious that point a cannot be greater than point b.

⟺ Choice C

The reason why choice C is not correct because if we solve the Inequality.

[tex]-b<-c[/tex]

We can either solve for b-term or c-term, the outcome would be the same. I'll solve for both terms.

⇨ Solve for b-term

[tex]-b<-c\\b>\frac{-c}{-1}\\b>c[/tex]

Also remember that moving a negative coefficient would swap the sign/operator of Inequality.

⇨ Solve for c-term

[tex]-b<-c\\\frac{-b}{-1}>c\\b>c[/tex]

As b>c is not true in the number line. We notice that c point is greater than b point.

Thus, the clear answer is A choice.
