The given modeled function is R(x)=26+1.5x

where R(x) is the number of hours spent reading a book over a month

and x is the number of hours a person spends at the library over the course of a month.

Representing R(x) on the y-axis and x on the x-axis,

Puttinv x=0 to get the R(x) intercept as

R=36+1.5 x 0 = 36

So, (0,36) ia a point.

Determining other-point by putting any arbitrary value of x other than 0.

Putting x=2, to get the other point

R=36+1.5 x 10 =51

So, the other point is (10,51).

Now, joining both the points to get the graph of the given linear equation as shown in the figure.

Answer:

(0,26) (4,32)

Step-by-step explanation:

The function R(x)=26+1.5x is a linear equation, so its graph is a straight line that can be drawn by plotting 2 points and connecting them.

Its R intercept occurs when x=0, so

y(0)=26,

and (0,26) is the R-intercept.

To find another point, plug in another x value into the function y(x). For example, when x=4, we have

R(4)=26+1.5(4)=32.

So, (4,32) is another point on the graph of R(x).

Answer:

Its c

Step-by-step explanation:

Let's write this question as a systems of equations to solve.

x-y=7 (the difference)

x+y=23 (the sum)

Through the process of elimination we get

2x=30

x=15.

With that value of x, we can plug it back into any of the previous equations to get the value of y.

(15)-y=7 (Solve for y)

y=8.

The two numbers are 15 and 8.

Answer:

The minimum guaranteed mileage is  [tex]x = 71489.55[/tex]

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 67900[/tex]

     The standard deviation is  [tex]\sigma = 2050[/tex]

Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as

    [tex]P( X \ge x ) =1- P( \frac{X - \mu }{\sigma } < \frac{ x - 67900 }{ 2050} ) = 0.04[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P( X \ge x ) =1- P( Z<z) = 0.04[/tex]

=>  [tex]P( X \ge x ) = P( Z<z) = 0.96[/tex]

=>    [tex]z = \frac{ x - 67900 }{ 2050}[/tex]

From the z table, the critical value corresponding to 0.96 to the left of the curve is  

         [tex]z = 1.751[/tex]

So

        [tex]1.751 = \frac{ x - 67900 }{ 2050}[/tex]

=>     [tex]x = 71489.55[/tex]

The solution is Option A.

The number of only children with no pets is given by the equation A = 63 and the percentage would be P = 37.5 %

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of only children with no pets be A

Now , the equation will be

The number of siblings with pets = 82

The number of siblings with no pets = 141

The number of only child with pets = 105

Now , let A = 63

So , the total number of children = 105 + 63 = 168

The percentage given is P = 37.5 %

So , the percentage of children with no pets P = ( number of only children with no pets / total number of children ) x 100

Substituting the values in the equation , we get

Percentage of children with no pets P = ( 63 / 168 ) x 100

Percentage of children with no pets P = 0.375 x 100

Percentage of children with no pets P = 37.5 %

Therefore , the value of A is 63

Hence , the number of children with no pets i 63

Step-by-step explanation:

72km/h = 72,000m/3,600s = 20m/s.

Using Kinematics, we have

v = u + at

= (20m/s) + (-2m/s²)(5s)

= 10m/s.

Hence the velocity will be 10m/s. (or 36km/h)

Answer:

92 people

Step-by-step explanation:

Since there is 20 people who liked both hot and cold beverages, we can subtract from the people who like hot beverages and people who like cold beverages to find the people who ONLY like hot beverages and the people who ONLY like cold beverages.

People who only like cold beverages:

40 - 20 = 20

People who only like hot beverages:

60 - 20 = 40

Summing it all up:

40 + 20 + 20 + 12 = 92 people total

Answer:

(130.08, 139.92)

Step-by-step explanation:

Given that:

Mean (m) = 135

Standard deviation (σ) = 30

Sample size (n) = 100

α = 90%

The confidence interval value is obtained using the relation:

Mean ± Zcritical * (standard deviation / sqrt(n))

Zcritical at 90% = 1.64

standard deviation / sqrt(n) = 30 / sqrt(100)

= 30 / 10 = 3

Hence,

135 ± 1.64 * (3)

Lower limit : 135 - (1.64 * 3) = 130.08

Upper limit : 135 + (1.64 * 3) = 139.92

Hence,

Confidence interval = (130.08, 139.92)
