Which relation is also a function?​

Answer:

y = 16.6

Step-by-step explanation:

y - 4.6 = 12

Add 4.6 to each side

y - 4.6+4.6 = 12+4.6

y = 16.6

Answer:

B  No

Step-by-step explanation:

4(5 + x)

To simplify the expression, we must use the distributive property. We need to multiply 4 by the each of the two terms inside the parentheses.

4(5 + x) = 4 × 5 + 4 × x = 20 + 4x

20 + 4x is equivalent to 4(5 + x).

20 + x is not equivalent to 20 + 4x, so 20 + x is incorrect.

Answer: B  No

Answer:

It will take 8.17 days for a news story to reach 1,500,000 shares.

Step-by-step explanation:

Note: The correct exponential model is as follows:

y = 5⋅7^x ......................................... (1)

Where:

y = 1,500,000

x = ?

Substituting y = 1,500,000 into equation (1), we have:

1,500,000 = 5⋅7^x ........................ (2)

Taking the natural log of both sides of equation (2) and solve for x, we have:

ln1,500,000 = xln5.7

x = ln1,500,000 / ln5.7

x = 14.2209756660724 / 1.7404661748405

x = 8.17241379310345

Approximating to 2 decimall places, we have:

x = 8.17

Therefore, it will take 8.17 days for a news story to reach 1,500,000 shares.

Answer: (0,0)

Step-by-step explanation:

got it correct

The value of y-intercept of the given function is (0,0).

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since, We know that;

When a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, tWhen a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, the y-intercept of the given function is (0,0),

Thus, The value of y-intercept of the given function is (0,0).

Población = Todos los pasajeros en el autobús

Muestra = los 10 pasajeros entrevistados

Variable = inocencia del conductor; por tanto es una variable cualitativa

Explicación paso a paso:

La población se refiere a todo el conjunto de observaciones que están relacionadas con un evento o experimento en particular. Aquí, todos los pasajeros del vehículo constituyen la población, ya que nuestra investigación se basa en el vehículo.

La muestra es un subconjunto de la población que generalmente se elige al azar de manera que sea representativa de la población.

La variable que pretendemos medir es si el conductor es inocente o no. Por lo tanto, llamamos a esto la variable medida. Debido a que la culpa o la inocencia no es numérica, se considera una variable cualitativa.

Answer:

7.14 in²

Step-by-step explanation:

A = LW

A = 2 x 2 = 4

-----------------------------------------------------------------------------------------------------------------

A = 3.14r²

A = 3.14 (1²)

A = 3.14 (1)

A = 3.14

-----------------------------------------------------------------------------------------------------------------

3.14 + 4 = 7.14

Answer:

0.122 = 12.2% probability that the student will have scored greater than 600 points on the quantitative section of the SATs.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean score of 501 points, and a standard deviation of 85 points.

This means that [tex]\mu = 501, \sigma = 85[/tex]

What is the probability that the student will have scored greater than 600 points on the quantitative section of the SATs?

This is 1 subtracted by the p-value of Z when X = 600. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{600 - 501}{85}[/tex]

[tex]Z = 1.165[/tex]

[tex]Z = 1.165[/tex] has a p-value of 0.878.

1 - 0.878 = 0.122

0.122 = 12.2% probability that the student will have scored greater than 600 points on the quantitative section of the SATs.

Explanation:

Add 4 to both sides

a-4 < 10

a-4+4 < 10+4

a < 14

The reason why we add 4 to both sides is to undo the "minus 4" that's happening to the variable.

Answer:

Angle of Arc θ = 200°

Step-by-step explanation:

Given:

Length of arc = 5π

Radius of circle = 4.5 unit

Find:

Angle of Arc θ

Computation:

Using length of arc formula

Length of arc = [θ/360][2πr]

Putting value or length of arc and radius in given formula;

5π = [θ/360][(2)π(4.5)]

5π = [θ/360][9π]

5 = [θ/360][9]

5 =  [θ/40]

θ = 40 x 5

θ = 200

Angle of Arc θ = 200°

Answer:

Area of heptagon = 712.26 square units

Step-by-step explanation:

Given the following data;

Side length = 14 units

A heptagon is a polygon with seven sides.

Mathematically, the area of a heptagon is given by the formula;

Area of heptagon = 3.634a²

Where;

a represents the side length.

Area of heptagon = 3.634 * 14²

Area of heptagon = 3.634 * 196

Area of heptagon = 712.26 square units

Answer:

16 in

Step-by-step explanation:

Because you multiply 4in by 3in and you get 12 in. and you subtract 3in by 1in to get the height for the smaller box and you get 2in so multiply 2in by 2in to get 4in and add your products to 12in and 4 in to get 16 in!

Step-by-step explanation:

Basically you want to find LCM which is the Least Common Multiple. This is the process of coming up with the smallest positive multiple that is common to two or more numbers.

Look up how to solve using cake ladder method. Basically you are going to list all numbers and use the same number to divide them in whole number without remainder. You do this until you encounter a point where you cannot further divide without remainder. Then you multiply the left most column and last row.

Answer:

y = 1.5x + 6

Step-by-step explanation:

Given the following data;

Points on the x-axis (x1, x2) = (-4, 0)

Points on the y-axis (y1, y2) = (0, 6)

To find the equation of line;

First of all, we would determine the slope of the line.

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {6 - 0}{0 - (-4)} [/tex]

[tex] Slope, m = \frac {6}{4} [/tex]

Slope, m = 1.5

To find the equation of line, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - 0 = 1.5(x - (-4))

y = 1.5x + 6
