Given :

Mr. Ford's 2002 Focus would get 36 miles/gallon.

He starts with 13.2 gallons of gas in his gas tank.

To Find :

Write a slope-intercept equation that models how much gas remains in his tank after each mile of of travel(hint: g/mi).

Solution :

Let, required equation is :

y = mx + c

Here, y is gas remains in gallons.

Here, m is slope i.e. miles travelled per gallon.

So, m = -36  ( since gas is decreasing )

Initially distance travelled is 0 i.e. putting x = 0

y = c = 13.2

Therefore, y = -36x + 13.2 this is the required equation.

Step-by-step explanation:

The probability of not winning the coupon at the grocery store given the probability of winning the coupon is 23/25.

Probability determines the likelihood of the occurence of an event. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability of not winning the coupon = 1 - probability of winning

1 - 2/25 = 23/25.

Answer:

Option B

Step-by-step explanation:

The p value is greater than 0.05.

Hence there are not enough evidences to reject the null hypothesis.

Basically no effect is observed when p>0.05

Hence, the test results are  statistically significant

Option B is correct

All points in Quadrant IV have a positive x-coordinate and a negative y-coordinate.

The fourth quadrant, indicated as Quadrant IV, is in the bottom right quadrant. The x-axis in this quadrant has positive values, whereas the y-axis has negative numbers.

A two-dimensional Cartesian system's axes split the plane into four infinite areas called quadrants, each of which is limited by two half-axes. These are frequently numbered from first to fourth.

A quarter of a circle; a 90° arc. the region enclosed by an arc and two radii are drawn one to each extreme. As a mechanical component, anything is shaped like a quarter of a circle.

All Quadrant I points have two positive coordinates.

Quadrant II points all have a negative x-coordinate and a positive y-coordinate.

Answer:

P (x>5) = 0.5324014=0.523

Step-by-step explanation:

Here success = p= 0.7 and failure = q= 1-p= 1-0.7 = 0.3

Number of surgeries= n= 8

Applying the binomial distribution

( p+q) ^n= nC x p^x . q^n-x

More than 5 means  6,7, and 8

( p+q) ^8= 8C 5 (0.7)^5 . (0.3)^3

                =56* 0.16807*0.027

                       = 0.254121

( p+q) ^8= 8C 6 (0.7)^6 . (0.3)^2

                =  28* 0.1177* 0.09

                    = 0.296604

( p+q) ^8= 8C 7 (0.7)^7 . (0.3)^1

                =  8* 0.0824* 0.3

                  = 0.19776

( p+q) ^8= 8C8 (0.7)^8 . (0.3)^0

                =  1* 0.05765* 1

                  =0.05765

Adding the above all probabilities  gives

P (x>5) = P (x=6) + P(x=7) + P(x=8)

               = 0.296604+0.19776+0.05765

                   = 0.5324014

After a work out, the simplest form of e:g is 3:10.

Ratio is an expression which shows the relationship between two numbers or variables. It can generally be expressed in two forms, viz; a:b or a/ b.

To work out the simplest form of e:g as required in the question,

e/ f = 2/ 5

2f = 5e ........... 1

f/g = 3/ 4

3g = 4f ........... 2

From equation 1,

f = 5e/2

substitute the value of f in equation 2

3g = 4(5e/2)

3g = 10e

Therefore, e:g is given as;

3/ 10 = e/ g

3:10 = e: g

Thus in its simplest form, e:g = 3:10

Answer:

Step-by-step explanation:

1. What are the x-intercepts of the graph representing f?  They are the points on the horizontal axis where the graph touches or crosses the axis.  Note that on this axis, y = 0.

2. What are the x- and y-coordinates of the vertex of the graph?  Since the function is written as the product of two binomials, we can take these coordinates directly from the binomials:  (x - 2) yields x = 2 and (x + 4) yields x = -4.

3. What is the y-intercept?   Multiply out these binomials.  We get:

f(x) = x^2 + 2 - 8.   When x = 0, y = -8.  The y-intercept is (0, -8).

1) The x-intercepts of the graph representing f are; 2 and 4

2) The x- and y-coordinates of the vertex of the graph are; (1, -5)

3) The y-intercept is at; (0, -8)

We are given the function; f(x) = (x - 2)(x + 4)

1) The x-intercepts of a graph are the points where the graph crosses the x-axis. The x-intercepts are the value of x when f(x) = 0. Thus, the x-intercepts here are 2 and 4.

2) The vertex is the lowest point of the graph in this case as the parabola opens upwards.

Let us expand the function to get;

f(x) = x² - 2x + 4x - 8

f(x) = x² + 2x - 8

where;  a = 1, b = 2, c = -8

Formula for the x-coordinate of the vertex is;

x = -b/2a

x = -2/2(1)

x = 1

Thus;

y =  (1 - 2)(1 + 4)

y = -5

x- and y-coordinates of the vertex of the graph are; (1, -5)

3) The y-intercept is the point at which x = 0. Thus;

y = 0² + 2(0) - 8

y = -8

The y-intercept is (0, -8).

What is an equation?

An equation is a statement of equality between two expressions. It uses the equal sign (=) to show that the expressions on either side of the sign have the same value.

For example 2x+3=5y-7z, and x+y=5 are examples of equations.

In solving your problem,

25 less than the sum of a number and 5 results in 15, can be written as an equation like this:

let x be the number we want to find.

x + 5 =15+25 (25 less than the sum of x+5)

x + 5 = 40

then

x=40-5

x=35

So the number is 35.

Answer:

y=-26.7x+14.1

hope this helps

have a good day :)

Step-by-step explanation:

Answer:

y=−26.7x+14.1

Step-by-step explanation:

y=−17.5x+2.7x+14.1−11.9x

y=−26.7x+14.1

Solve for x:

Step 1: Flip the equation.

−26.7x+14.1=y

Step 2: Add -14.1 to both sides.

−26.7x+14.1+−14.1=y+−14.1

−26.7x=y−14.1

Step 3: Divide both sides by -26.7.

x=−0.037453y+0.52809

Solve for y:

y=−26.7x+14.1

-9/7 is the inverse of 9/7.

-9/-7 = 9/7

9/7 + (-9/7) = 0

-9/7 is consequently the additive opposite of -9/-7.

By merely switching the integer's sign, you can add the original number and the additive inverse to produce a result equal to 0. The value that, when added to the original number, results in zero is known as a number's additive inverse. It is what we add to a number to make it equal to zero. Considering that an is the starting number, its additive inverse will be a minus one, or -a, such that;

a+(-a) = a – a = 0

Answer:

The box must be 2.4 in deep.

Step-by-step explanation:

Front dimensions are 9 in by 7.5 in.  Find the area of the front:  it is

A = (9 in)(7.5 in) = 67.5 in^2.  One way to complete this work would be to divide the given volume by this area, 67.5 in^2.  

A slightly different approach follows:

The volume must be 162 in^2.  Given V = (width)(height)(depth),

                                   V

(depth) must be -----------------------

                            (width)(height)

In this particular case,

                                162 in^3

(depth) must be ----------------------- = 2.4 in

                              (7.5 in)(9 in)

The box must be 2.4 in deep.

Rectangle

Step-by-step explanation:

If the base is a square that means the cross-section can also be a square.

Step-by-step explanation:

y = 2x + 1 -------- (I)

y = 4x + 6 --------(ii)

from eqn (I)

y = 2x + 1

sub y = 2x + 1 in eqn (ii)

2x + 1 = 4x + 6

2x - 4x = 6 - 1

-2x = 5

x = -5/2

sub x = -5/2 in eqn (I)

y = 2(-5/2) + 1

y = -5 + 1

y = -4

Therefore, (x, y) = (-5/2, -4)

Object distance, u = -6 cm

Step-by-step explanation:

Given that,

The radius of curvature, R = 15 cm

The radius of the mirror, f = -7.5 cm

We need to find the object's distance from the mirror. The mirror's formula is used to find the object distance such that,

[tex]\dfrac{1}{f}=\dfrac{1}{u}+\dfrac{1}{v}\\\\\dfrac{1}{u}=\dfrac{1}{f}-\dfrac{1}{v}\\\\\dfrac{1}{u}=\dfrac{1}{(-7.5)}-\dfrac{1}{30}\\\\u=-6\ cm[/tex]

So, the object distance is 6 cm.
