fee of $4 plus a camping fee of $20 per
night. This can be represented by the
function f(x)
20x +4, where f(x) is the total
cost and x is the number of nights spent
camping. What is the value of f(5), which is
the cost of 5 nights of camping? (Lesson 2-1)
A. 80

Answer:

5 year

3 inches every year 48 minus 32 equals 16 3 Inches divided into 16 equal 5.333333 round it equals 5 years y = 5 years

The another point is  (2,23) of the function y(x).

What does regression analysis mean?

The given Regression is -

y (X) = 30 - 3. 5 x .......................(1)

now   when x = 0 , y(x) = 30    ..........................(1)

thus ,   y- intercept  = 30

one point is    ( 0 , 30 )

Again taking   x = 0  we get

             y(x) =   30 - 3. 5  x 2    by (1)

               y(X) = 23

Thus the another point is  (2,23).

If the chi-square value is going on English the likelihood of rejecting the null hypothesis also increases because there is a chance that the chi-square value increases more than the significant value that is given in the question. So the required answer is that increases as the required answer.

For example, if, according to Mendel's laws, you expected 10 of 20 offspring from a cross to be male and the actual observed number was 8 males, then you might want to know about the "goodness to fit" between the observed and expected.

Were the deviations (differences between observed and expected) the result of chance, or were they due to other factors? How much deviation can occur before you, the investigator must conclude that something other than chance is at work, causing the observed to differ from the expected.

The chi-square test is always testing what scientists call the null hypothesis, which states that there is no significant difference between the expected and observed result.

The formula for calculating chi-square ( 2) is:

The graph that represents the inequality is graph b

From the question, we are to graph the given inequality

The given inequality is

y ≥ |x+5|-3

To graph the inequality, we will write the inequality as an equation and we will find some of the points on the line

When x = 0

y = |x+5|-3

y = |0+5|-3

y = |-3

When y = 0

y = |x+5|-3

0 = |x+5|-3

0 = (x + 5) - 3 and 0 = -(x + 5) -3

3 = x + 5

x = 3- 5

x = -2

and

0 = -(x + 5) -3

x + 5 = -3

x = -3 - 5

x = -8

The graphs that has the points above are graphs b and d.

Since the inequality sign is ≥ when y is the subject, the solution to the inequality is above the lines.

Hence, the graph of the inequality is graph b.

The key to this is to know what a remote angle is. A remote angle is one that has one leg in common with the exterior angle. Make this a little simpler.

The exterior angle is outside the triangle. In this case it is the 157 degree angle.

The two remote angles each contribute just one side to the exterior angle. <B contributes BC and <A

Theorem

The two remote angles = the exterior angle.

Equation

x + x - 21 = 157

Solution

x + x - 21 = 157                    Combine the left side

2x - 21 = 157                       Add 21 to both sides

2x - 21 + 21 = 157+21         Combine  

2x = 178                             Divide by 2

2x/2 = 178/2

x = 89

Step-by-step explanation:

completing the square means finding an expression

(x + a)² = b²

or

(x - a)² = b²

(x + a)² = x² + 2ax + a²

(x - a)² = x² - 2ax + a²

because of the "+ 18x" in the original equation we know that we are looking for (x + a)².

now, let's compare the different terms :

x² = x²

18x = 2ax

18 = 2a

a = 9

so, the complete square would look like

(x + 9)² = x² + 18x + 81

but we have only "+ 79" in the original equation.

so, we add the missing 2 (to both sides to keep the equation true)

x² + 18x + 79 + 2 = 0 + 2

x² + 18x + 81 = 2

(x + 9)² = 2

x + 9 = ±sqrt(2)

x1 = sqrt(2) - 9

x2 = -sqrt(2) - 9

x = sqrt(2) - 9, -sqrt(2) - 9

yes, every quadratic equation has 2 solutions.

as every cubic equation has 3 solutions.

and so on.

The solution of the equation for h is H = 2a/(B1 + B2)

Expressions are mathematical statements that are represented by variables, coefficients and operators

The equation is given as

a=H(B1 + B2)/2

The above means that the variable h is represented by the variable H

Multiply both sides of the equation by 2

So, we have

2a = H(B1 + B2)

Divide both sides of the equation by (B1 + B2)

H = 2a/(B1 + B2)

Hence, the solution of the equation for h is H = 2a/(B1 + B2)

The function with the largest slope would be f(x) = 1.5

What is the slope in math?

For f(x), choose any two points say (-3,-10) and (-1,-7) where

x1 = -3 ; y1 = -10 ; x2 = -1 ; y2 = -7

Find the slope (m)

m=(y2 - y1) / (x2 - x1) = (-7 - -10)/ (-1 - -3) = 3/2 or 1.5

slope of f(x) = 1.5

g(x) = 1/2 x  + 3

standard formula: y = mx + b where m is the slope.

slope of g(x) = 1/2 or 0.5

Since lance gains 1 level every time he plays,

slope = 1/1 = 1 so, slope of h(x) = 1

  Higher than 500 so round up to get 3,000

2,739 and 2500 are both possible solutions.

The value of 50-cents coins is $21, the value of 10-cents coins is $15 and the value of the 20-cents coins is $14.

Percentage of the number:

Percentage is defined as the a number or ratio that can be expressed as a fraction of 100.

If we have to calculate percent of a number, divide the number by the whole and multiply by 100.

Given,

Roslan had a total of 50$ in 10-cents coins,20- cent coins and 50-cents coins.

The value of his 10- cents coins was 30% of the total value of all his coins.

The value of his 20-cents coins was 28% of the total value of all his coins.

Here we need to find the value of 50-cent coins.

We know that,

Total value = $50

So the value of 10-cent coins

=> 30% × $50 = $15

Then the value of 20-cent coins

=> 28% × $50 = $14

Through the known values of 10-cents and 20-cents we have calculate the value of 50-cents coins as,

=> $50 – $15 – $14 = $21

Therefore, the value of 50-cents coins is $21.

The area of the parallelogram is [tex]\sqrt{132}[/tex].

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. Sum of all the interior angles equals 360 degrees.

Given that,

vertices k(1, 1, 3), l(1, 3, 5), m(6, 9, 5), and n(6, 7, 3)

Area of Parallelogram = |KL × KN|
