The points (20, 80) and (30, 120) form a proportional relationship. What is the slope of the line that passes through these points?

Answers

Answer 1
Slope = (y2-y1)/(x2-x1)
(120-80)/(30-20)
= (90)/(10) = 9
The slope is 9

A game of chance is played using a six-sided die. If a 1,2 or 3 is rolled the player wins $0 if a 4 or 5 is rolled the player wins $7. If a 6 is rolled the player wins $10. If each play of the game costs 5$ what is the expected pay off?

Answers

Answer:

-2.50

Step-by-step explanation:

Using the formula for the expected value, it is found that the expected pay off is of -$1.

The expected value is given by the sum of each outcome multiplied by it's respective probability.

In this problem, the outcomes and probabilities are, considering the cost of the game of $5 and that there are 6 sides:

[tex]\frac{3}{6}[/tex] probability of losing $5.[tex]\frac{2}{6}[/tex] probability of winning $2.[tex]\frac{1}{6}[/tex] probability of winning $5.

Hence:

[tex]E(X) = \frac{3}{6}(-5) + \frac{2}{6}(2) + \frac{1}{6}(5) = \frac{3(-5) + 2(2) + 1(5)}{6} = -\frac{6}{6} = -1[/tex]

The expected pay off is of -$1.

=8/8

=1

The value of (f o g)(-1) is 1 if the function f(x) =  8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

Two functions:

f(x) =  8/(x + 2)

g(x) = 4x² + 2

g(-1) = 4(-1)² + 2

g(-1) = 4 + 2

g(-1) = 6

f(g(-1)) = 8/(x + 2)

f(g(-1)) = 8/(6 + 2)

f(g(-1)) = 8/8

f(g(-1)) = 1

Thus, the value of (f o g)(-1) is 1 if the function f(x) =  8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

Joanne hit a ball straight up into the air. The height of the ball in meters, is given by the function h(t)= -5(t-3)^2+45 t seconds after the ball is hit. What is the maximum height the ball will reach

Answers

9514 1404 393

Answer:

  45 meters

Step-by-step explanation:

The equation is given in vertex form:

  h(t) = a(t -b)^2 +c

where (b, c) is the vertex (maximum).

The values of the parameters are ...

  a = -5, b = 3, c = 45

Then the maximum height is (time, height) = (3, 45).

The maximum height of the ball is 45 meters.

Insert a rational number between 1/2 and 1/3 by mean method?​

Answers

Answer:

[tex]\frac{5}{12}[/tex]

Step-by-step explanation:

To find a rational number by the mean method.

Add the 2 fractions and divide the result by 2

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex]

To add the fractions we require them to have a common denominator.

The LCM of 2 and 3 is 6 ← required common denominator

Multiply numerator/denominator of first fraction by 3

Multiply numerator/denominator of second fraction by 2

= [tex]\frac{1(3)}{2(3)}[/tex] + [tex]\frac{1(2)}{3(2)}[/tex]

= [tex]\frac{3}{6}[/tex] + [tex]\frac{2}{6}[/tex] ( add numerators, leaving denominator )

= [tex]\frac{5}{6}[/tex]

Now divide by 2

[tex]\frac{5}{6}[/tex] ÷ 2 leave first, change division to multiplication, turn second upside down )

= [tex]\frac{5}{6}[/tex] × [tex]\frac{1}{2}[/tex]

= [tex]\frac{5}{12}[/tex]

This is the fraction midway between the 2 given fractions

Find the equation of the linear function represented by the table below in slope-intercept form. x y -1 3 1 1 3 -1 5 -3

Answers

Answer:

y = - x + 2

Step-by-step explanation:

Points given:

(-1, 3), (1, 1), (3, -1), (5, -3)

Slope-intercept form:

y = mx + b

Finding the slope using slope formula and the first two points:

m = (1 - 3)/(1 - (-1)) = -2 / 2 = -1

Finding y-intercept using the slope and the first point:

3 = (-1)*(-1) + b3 = 1 + bb = 3 - 1b = 2

So the equation is:

y = - x + 2
