Find the area of the figure. Explain your reasoning.

Answer: 3/10

Step-by-step explanation: It's 3/10 because the total amount when you add all the numbers together is 120, and since he spins it 120 times, we could assume that 36 would be the amount of times that it would land on it based on the data given. We're not done yet though. You do 36/120 to get the probability, and you simplify it to get 3/10.

The probability that Ricardo spins blue on his next spin is 0.3

We could use the principle of experimental probability to determine the probability of spinning blue on next spin :

Given that :

Red: 35

Blue: 36

Green: 32

Yellow: 8

Orange: 9

Experimental probability = (number of times event occur / total number of trials)

Total number of trials = (35 + 36 + 32 + 8 + 9) = 120

The experimental probability of spinning blue is thus :

(Number of blue spins / total number of spins)

= 36 / 120

= 0.3

The probability of spinning blue on next spin is 0.3

Answer:

k = 10

Step-by-step explanation:

The constant of proportionality of a graph in Mathematics is simply the ratio of y to x which can be called the slope.

It's given by; k = y/x

We are given; y = 30 and x = 3.

Thus;

k = 30/3

k = 10

Answer:

Ok, we know that we can write a horizontal translation as:

y' = f(x - A)

where if A is positive, this moves the graph of f(x) A units to the right.

Why is this?

Ok, let's compare:

y = f(x)

and

y' = f(x - A)

in y, when x = 0 we have f(0).

While to have this same point in y', we need to evaluate in x = A.

f(A - A) = f(0).

Then the value f(0) is now at x = A, this means that the point moved A units to the right.

And you can do this for all the values, so you will find that the entire graph of f(x) has ben moved A units to the right.

Answer: explain how to graph an equation in slope-intercept form.

Step-by-step explanation: To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

Step-by-step explanation:

Answer:

(b) x > 26 cookies

Step-by-step explanation:

The selling price of 1 super-sized cookie, S.P.=$1.50

Let a batch have x cookies.

So, the selling price of x cookies=1.5x

The expences in making one batch of cookies=$10

So, net profit = 1.5x-10

The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.

As she wants to make a profit of at least $30, so for this condition, the value of y is 30.

Now, the given inequality become,

[tex]1.5x - 10 >30[/tex]

[tex]\Rightarrow 1.5x>30+10[/tex]

[tex]\Rightarrow x>\frac{40}{1.5}[/tex]

[tex]\Rightarrow x>26\frac{2}{3}[/tex]

As x is the number of cookies, so, it can't have a fractional value. This can be written as

[tex]x>26[/tex] or [tex]x\geq27.[/tex]

So, she has to sell more than 26 cookies to make a profit of at least $30.

Hence, option (b) is correct.

Option D is the correct answer, y = 3x + 7

The line is y=3x+7

Given that the point is (-3, -2) and slope=m=3.

Using the point slope formula we get:

[tex]y-\left(-2\right)=3\left(x-\left(-3\right)\right)\\y+2=3\left(x+3\right)\\y+2=3x+9\\y=3x+7[/tex]

The line is y=3x+7

Answer:

Yes, the price the school pays each year in entrance fees is proportional to the number of students entering the zoo

Step-by-step explanation:

Relationships between two variables is proportional if their ratios are equivalent.

In 2010, the school paid $1,260 for 84 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1260:84=15:1[/tex]

In 2011, the school paid $1,050 for 70 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1050:70=15:1[/tex]

In 2012, the school paid $1,395 for 93 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = [tex]1,395:93=15:1[/tex]

As [tex]1260:84=1260:84=1,395:93=15:1[/tex],

the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.

Answer:

  y +4 = 1/5(x +5)

Step-by-step explanation:

The equation of a line with slope m through point (h, k) in point-slope form is ...

  y -k = m(x -h)

You have m=1/5, (h, k) = (-5, -4). Putting these values into the formula gives ...

  y -(-4) = (1/5)(x -(-5))

  y +4 = 1/5(x +5)

Step-by-step explanation:

Equation of the Parabola

The general form of the equation of the parabola is:

[tex]f(x)=ax^2+bx+c[/tex]

We can try to find the values of a,b, and c by using the three given points (1,0),(-3,0),(-9,28).

However, we'll use an easier method. There is another form of the parabola in case we know its roots, also called zeros or x-intercepts. If p and q are the roots of f, then f can be expressed as:

[tex]f(x)=a(x-p)(x-q)[/tex]

We already know the values of p=1 and q=-3, thus replacing them into the equation, we have:

[tex]f(x)=a(x-1)(x+3)[/tex]

We only need to find the value of a. We do that by using the point (-9,28):

[tex]28=a(-9-1)(-9+3)[/tex]

Operating:

[tex]28=a(-10)(-6)=60a[/tex]

Solving for a:

[tex]\displaystyle a=\frac{28}{60}=\frac{7}{15}[/tex]

Thus, the equation of the parabola is:

[tex]\boxed{\displaystyle f(x)=\frac{7}{15}(x-1)(x+3)}[/tex]
