Step-by-step explanation:

7h - 5 = 4

    7h = 9

      h = 9/7

21(9/7) - 15 = 12

Answer:  11 down and 9 right

Step-by-step explanation:

Slope IS rise over run where the top number of the fraction (numerator) determines the vertical distance --> positive is up, negative is down

and the bottom number of the fraction (denominator) determines the horizontal distance --> positive is right, negative is left.

Given slope = -11/9

the numerator is -11 so the "rise" is  DOWN 11 units

the denominator is 9 so the "run" is RIGHT 9 units

The spreadsheet formula that would correctly calculate the average (mean) of the given values is: (25 + 50 + 75) / 3 = 50.

An average is a single number taken as representative of a list of numbers, generally the sum of the numbers divided by how many numbers are in the list (the arithmetic mean).

The formula to calculate the average of given numbers is equal to the sum of all the values divided by the total number of values. Average = Sum of Values / Number of Values.

So, in this case:

Values: 25, 50, 75

Number of Values: 3

Thus, the average:

Sum of Values / Number of Values = (25 + 50 + 75) / 3 = 50

Hence, the spreadsheet formula that would correctly calculate the average (mean) of the given values is: (25 + 50 + 75) / 3 = 50.

The probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001

In a series of 36 trials, if the subject is guessing randomly, then the probability of correctly guessing odd or even is 1/2.

Let X be the number of correct guesses in a series of 36 trials. X follows a binomial distribution with parameters n = 36 and p = 1/2.

The probability of guessing more than 20 correct is:

P(X > 20) = 1 - P(X ≤ 20)

Using a binomial distribution table, we can find that P(X ≤ 20) = 0.9999 (rounded to four decimal places).

Therefore: P(X > 20) = 1 - 0.9999 = 0.0001

So the probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001 (rounded to four decimal places).

The solution set for the inequality - x < 2 is - x < 2.

What is  inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

An inequality in mathematics depicts the connection between two values in an unbalanced algebraic statement. A sign of inequality can be used to show that one of the two variables is larger than, more than or equal to, less than, or equal to another value.

\(~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(h,k)}\\\\ \stackrel{a~is~negative}{op ens~\cap}\qquad \stackrel{a~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] ~\dotfill\)

Answer:

y = -3(x + 1)^2 + 2

Step-by-step explanation:

y = a(x - h)^2 + k is the vertex form of a quadratic, where

Finding (h, k):

We see from the graph that the vertex is a maximum and its coordinates are (-1, 2).  Thus h is -1 and k is 2.  Since h becomes negative, it will be 1 in the parentheses: (x - (-1) = (x + 1).

Finding a:

In order to find a, we will need to plug in a point on the parabola for (x, y) and (-1, 2) for h and k.  We see that (0, -1) lies on the parabola so we can use this point for (x, y).

-1 = a(0 - (-1))^2 + 2

-1 = a(0 + 1)^2 + 2

-3 = a(1)^2

-3 = a

Thus, a = -3.

Thus, the exact equation in vertex form of the parabola is:

y = -3(x + 1)^2 + 2

Answer:

a) Price of admission is $12.50

b) linear equation: 1.25x + 12.5 = y

slope: 1.25

y-intercept: 12.5

The equation above is in slope-intercept form

Here's the work step by step :)

hope it helps!

Step-by-step explanation:

$1.25 is the cost per ticket

Jermaine bought 25 tickets in total

Spent a total of $43.75

y = total cost

x = number of ride tickets

1.25 ( 25 ) = 31.25

31.25 is the total money spent on ONLY tickets.

To find the cost of admission...

43.75 - 31.25 = 12.50

The cost of admission is $12.50

Equation: 1.25x + 12.5 = y

(1.25 is the cost per ticket and 12.5 is the intial charge/admission fee and y is the total cost)

y = mx + b

m= slope and b= y - intercept

1.25x + 12.5 = y

slope: 1.25

y - intercept: 12.5

Given:

The equation of a line is:

\(2y+3x=10\)

The line is dilated by factor 3.

To find:

The result of dilation.

Solution:

The equation of a line is:

\(2y+3x=10\)

For \(x=0\),

\(2y+3(0)=10\)

\(2y+0=10\)

\(y=\dfrac{10}{2}\)

\(y=5\)

For \(x=2\),

\(2y+3(2)=10\)

\(2y+6=10\)

\(2y=10-6\)

\(2y=4\)

Divide both sides by 2.

\(y=\dfrac{4}{2}\)

\(y=2\)

The given line passes through the two points A(0,5) and B(2,2).

If the line dilated by factor 3 with origin as center of dilation, then

\((x,y)\to (3x,3y)\)

Using this rule, we get

\(A(0,5)\to A'(3(0),3(5))\)

\(A(0,5)\to A'(0,15)\)

Similarly,

\(B(2,2)\to B'(3(2),3(2))\)

\(B(2,2)\to B'(6,6)\)

The dilated line passes through the points A'(0,15) and B'(6,6). So, the equation of dilated line is:

\(y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\)

\(y-15=\dfrac{6-15}{6-0}(x-0)\)

\(y-15=\dfrac{-9}{6}(x)\)

\(y-15=\dfrac{-3}{2}x\)

Multiply both sides by 2.

\(2(y-15)=-3x\)

\(2y-30=-3x\)

\(2y+3x=30\)

Therefore, the equation of the line after the dilation is \(2y+3x=30\).

The slope of a line is given by:

where (x1,y1) and (x2,y2) are two points through the line.

From the graph we notice that the line passes through the points (0,0) and (4,3). Plugging this values into the expression for the slope we have:

Therefore the slope is 3/4.

Now, the equaiton of a line is given as:

where m is the slope and b is the y-intercept. We already have the slope and from the graph we have that the y-intercept is zeo, then b=0. Plugging the values we have that the equation is:

The system of equations is.

\(\begin{cases}\text{x}+\text{y}=60 \\15\text{x}+10\text{y}=800 \end{cases}\)

And the solutions are y = 50 and x = 10.

Let's define the two variables:

With the given information we can write two equations, then the system will be:

\(\begin{cases}\text{x}+\text{y}=60 \\15\text{x}+10\text{y}=800 \end{cases}\)

Now let's solve it.

We can isolate x on the first  to get:

\(\text{x} = 60 - \text{y}\)

Replace that in the other equation to get:

\(15\times(60 - \text{y}) + 10\text{y} = 800\)

\(-2\bold{y} = 900 - 800\)

\(-2\bold{y} = 100\)

\(\text{y} = \dfrac{100}{-2} = \bold{50}\)
