Answer:

2

Step-by-step explanation:

Use BODMAS(bracket, of, division, multiplication, addition and subtraction)

72/8=9

(6*4)=24

24/12+9-9

2+0

=2

The solution for the given operations of numbers is 2.

PEMDAS rule is the same as BODMAS rule.

PEMDAS is the abbreviation for Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.

We are using BODMAS rule here to solve the given operations.

6 * 4 ÷ 12 + 72 ÷8 - 9

According to the rule, first we should do multiplication.

6 × 4 = 24

6 * 4 ÷ 12 + 72 ÷8 - 9 = 24 ÷ 12 + 72 ÷8 - 9

Next do the division.

24 ÷ 12 = 2 and 72 ÷8 = 9

24 ÷ 12 + 72 ÷8 - 9 = 2 + 9 - 9

Now do the addition and subtraction.

2 + 9 - 9 = 2

Hence the final answer for the given operation is 2.

Answer:

The roots of the equation is real and repeated

Step-by-step explanation:

Here, we want to describe the nature of the roots of the given quadratic equation

To get the nature of the roots, we find the discriminant of the equation

The discriminant is;

b^2 - 4ac

In this case, b = -28 , a = 49 and c = 4

The discriminant is thus;

-28^2 - 4(49)(4)

= 784 - 784 = 0

Since the discriminant is zero, this means that the quadratic equation has real roots which are the same

Answer:

The correct option is;

The situation shows correlation without causation

Step-by-step explanation:

The given data are;

Weight y     [tex]{}[/tex]            Miles Per Gallon

42     [tex]{}[/tex]                           18

36     [tex]{}[/tex]                           12

30     [tex]{}[/tex]                            6

.     [tex]{}[/tex]                                x

24     [tex]{}[/tex]                            0

The first difference of the data = 42 - 36 = 36  - 30 = 30 - 24 = 6

18 - 12 = 12 - 6 = 6 - 0 = 6

The first difference of the data is constant and equal to 6

Therefore, the graph is a straight line graph with y-intercept = 24 and slope given by the rate of change of the weight to the miles per gallon of fuel consumption as follows;

The rate of change of the weight to the miles per gallon of fuel consumption is given as follows;

(42 - 24)/(18 - 0) = 1

Therefore, the points of the data fit into the straight line and the data of the situation shows correlation

In order to show causation, and to rule out other possible causes for the rise in MPG, a separate experiment will be required whereby the cause for the rise in MPG can be determined.

Answer:

The situation shows correlation with causation.

Step-by-step explanation:

A correlation between two variables is a measure of the strength of the association between them.

It can be seen from the scatter plot that as the weight of the car increases, the miles per gallon decreases.

Causation between variables indicates that one of the variables causes the other variable to occur. Causation between variables always implies correlation.

The weight of the car affects the miles per gallon because cars that weigh more require more power to move. Hence, heavier cars get lower miles per gallon of fuel.

Therefore, the situation shows correlation with causation.

Answer:

(-4,-6)

Step-by-step explanation:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The point of intersection between the two equations is (-4, -6).

The graph is given below.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 6 is an equation.

We have,

y = 2x + 2

y = x - 2

Now,

The point of intersection.

2x + 2 = x - 2

2x - x = -2 - 2

x = -4

Putting in y = 2x + 2

y = 2 x -4 + 2

y = -8 + 2

y = -6

(-4, -6) is the point of intersection.

Now,

The graph of the equation is given below.

Thus,

The point of intersection between the two equations is (-4, -6).

The graph is given below.

Lets find the rate of change first;

[tex]\frac{y^{2}-y^{1} }{x^{2}-x^{1} }=\frac{15-5}{19-9}=\frac{10}{10}=1[/tex]

Answer:

−2(−9x+5)−4x=2(x−5)−4

Step 1: Simplify both sides of the equation.

−2(−9x+5)−4x=2(x−5)−4

(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)

18x+−10+−4x=2x+−10+−4

(18x+−4x)+(−10)=(2x)+(−10+−4)(Combine Like Terms)

14x+−10=2x+−14

14x−10=2x−14

Step 2: Subtract 2x from both sides.

14x−10−2x=2x−14−2x

12x−10=−14

Step 3: Add 10 to both sides.

12x−10+10=−14+10

12x=−4

Step 4: Divide both sides by 12.
