Naomi asked several classmates how much cash they had in their pocket. She recorded the data below:

$1.50, $5, $9, $2, $0, $22, $4.75, $11.50, $4, $3, $7.50, $5, $0.75, $2.25, $8

A. Use the data to make a frequency table. Make the intervals go by 5's.

B. Use the frequency table to make a histogram.

C. One of your intervals should be "empty". What does the empty interval mean?

Answer:

Step-by-step explanation:

Answer A is not correct because if the kite moves both right and up, the x and y coordinates will change

Answer B is the same as answer A. The kite moved so the coordinates will change.

Answer D is also the same. If the kite moves both on the x and y axis, any angle and distance will change.

Answer C is correct. Since C does not rely on the coordinates, it will always be the same. The position of a shape does not change it´s perimeter.

Answer:

8x^3+2x^2-3x+4

Step-by-step explanation:

8x³ +2x² -3x+4 is the standard form of the  (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)

An expression is combination of variables, numbers and operators.

The given expression is  (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)

7x³ + 7x² – 4+x³ – 5x² – 3x + 8

In the given expression x is the variable

Plus and minus signs are the operators of the given expression.

Add the like terms in the given expression

8x³ +2x² -3x+4

Hence, 8x³ +2x² -3x+4 is the standard form of the  (7x³ + 7x² – 4) + (x³ – 5x² – 3x + 8)

they are parallel so they won't intercept. therefore they won't have a solution

Answer:

No, these triangles are not similar.

Step-by-step explanation:

If they were similar by ratio you would be able to divide 3/8 and 4/10 and get the same decimal but instead you get 0.375 for 3/8 and 0.4 for 4/10.

Step-by-step explanation:

Answer: f(x) = 64 * (3/4)^x

Step-by-step explanation: f(x)=ab^x

When x=0 f(x) = 64

64 = ab^0

b^0 =1 so

64 =a

f(x)=64 b^x

When x=1 f(x) = 48

48 = 64 *b

Divide by 64

48/64 =b

6/8 =b

3/4 =b

f(x) = 64 * (3/4)^x

Answer:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Step-by-step explanation:

We are given that a frog leaps two feet, with the highest point in the jump being six inches.

Assuming the frog starts at (0,0), we want to find a quadratic function in vertex form for the path of the jump.

First, we will convert the length of the jump to inches. Two feet is equivalent to 24 inches.

Next, since the frog started at (0, 0), in order to jump a length of 24 inches, it must have ended at (0, 24). These two points will also be our two roots: x = 0 and x = 24. We can use the factored form of a quadratic:

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

Where p and q are the roots.

Substitute in the roots:

[tex]f(x)=a(x-0)(x-24)=ax(x-24)[/tex]

Now, since the frog reached a maximum height of six inches, the y-coordinate of the function at its vertex point is 6.

Since a parabola is symmetrical along its axis of symmetry, the axis of symmetry is always halfway between the two roots.

Therefore, the x-coordinate of our vertex is:

[tex]\displaystyle x=\frac{24-0}{2}=12[/tex]

So, when x = 12, f(x) = 6. Substitute:

[tex]6=a(12)(12-24)[/tex]

Solve for a:

[tex]\displaystyle- 144a=6\Rightarrow a=-\frac{1}{24}[/tex]

Therefore, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}x(x-24)[/tex]

Now, we can place this into vertex form:

[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]

Where a is the leading coefficient and (h, k) is the vertex.

Our leading coefficient is -1/24, and the vertex is (12, 6). Hence, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Step-by-step explanation:

Answer: A. $30.00

Step-by-step explanation:

1. Find the common difference, or by how much the value changes per pound.   Divide the price of the sales by the amount of pounds to find the rate. The rate must be $2.50 since 10 ÷ 4 = 2.5. To confirm, use 2 or 3 pairs of values. 15 ÷ 6 = 2.5, which confirms that the common difference is 2.5. This means that every pound of asparagus is $2.5.

2. Now that the rate is known, multiply it by 12. 2.5 * 12 = $30.00, which is the final answer.

Each of these is proportional to the other. Meaning, if you put the price over the pounds, then you get a fraction that remains consistent throughout the entire table and beyond.

[tex]\frac{price}{pounds}=\frac{10}{4} =\frac{5}{2}[/tex] so [tex]\frac{5}{2}[/tex] will be our constant ratio. With our formula, we know that the two equal each other, so [tex]\frac{price}{pounds}=\frac{5}{2}[/tex].

[tex]\frac{x}{10}=\frac{5}{2}\\[/tex] so [tex]2x=50\\x=25[/tex]

[tex]\frac{x}{12}=\frac{5}{2}[/tex] so [tex]2x=60\\x=30[/tex]

12 pounds of asparagus is $30.00

12^9

Answer:

12^9

Step-by-step explanation:

12^8 * 12^-8

according to law of integers, since both numbers are the same we can work with their roots, and the multiplication would be addition;

8+(-8)= 0

(12*12)^0 ----numerator

(denominator)

12^-9

division = subtraction in the laws of integers

0-(-9)= 0+9=9

(12*12)/12= 12
