Answer:

Step-by-step explanation:

Mary bought 1 fish, Ari bought 20 fish, Rodney bought 4 fish, Carissa bought 3 fish, Jacob bought 4 fish, Jack bought 1 fish, Jaleesa bought 2 fish, Andrea bought 5 fish, Geoff bought 1 fish, Becky bought 4 fish, Molly bought 1 fish, David bought 2 fish, Gina bought 7 fish, James bought 1 fish, Anessa bought 2 fish, Ted bought 1 fish, Sean bought 2 fish, Kerri bought 11 fish, Sammy bought 3 fish, Jameson bought 2 fish, Theresa bought 2 fish, Luz bought 2 fish, Tracy bought 4 fish, Jackson bought 5 fish, and Celia bought 7 fish.

Rewrite the numbers

1,20,4,3,4,1,2,5,1,4,1,2,7,1,2,1,2,11,3,2,2,2,4,5,7

1.

a: I can't draw a line plot, but I can tell you some tips.

Set the x as the different numbers that appear in the set

Set the y as the frequency of each number.

b: 2 fish has the highest frequency.

c: Add the terms. 97 is the total fish been bought

d: The outlier is 20 bought fish

2.

a: When making the stem and leaf plot, do it in this format

1| 7,4,3,5,8,4

and so on.

b: the heaviest puppy is 25 and the lightest is 13

so the range is 12

c: 4 puppies weighed at least 20 pounds

3. There are no following values, but for this I would make a box and whisker plot.

4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.

a: Find the frequency of each bar and add them.

b: the largest number of boxes is the interval that is the largest

c: Use the graph to find it

d: I can't do this without the graph.

The linear relationship is y = 20x, 0 ≤ x ≤ 17.5 and the quadratic relationship is y = -16x² + 288, 0 ≤ x ≤ 3√2

<h3>The equations that represent the relationships</h3>

<u>The linear relationship</u>

When making the trip up, we have:

Rate = 20 feet per seconds

This means that the relationship is:

Distance = Rate * Time

So, we have:

y = 20x

The height of the tower is 350.

So, we have:

20x = 350

Divide by 20

x = 17.5

Hence, the linear relationship is y = 20x, 0 ≤ x ≤ 17.5

<u>The quadratic relationship</u>

The quadratic equation can be represented as:

y = -0.5ax² + vx + h

Where:

  • a = acceleration due to gravity = 32
  • v = velocity = 0
  • h = height = 288

So, we have:

y = -0.5 * 32x² + 0 * x + 288

Evaluate

y = -16x² + 288

When you get to the ground level, we have:

-16x² + 288 = 0

Subtract 288 from both sides

-16x² = -288

Divide by -16

x² = 18

Take the square root of both sides

x = ±3√2

Remove negative domain

x = 3√2

Hence, the quadratic relationship is y = -16x² + 288, 0 ≤ x ≤ 3√2

An apple IPod sells for 299, which is marked up 40% of the selling price. What is the cost of the iPod ?
Shalnov [3]

Answer:

\large \boxed{213.57}

Step-by-step explanation:

Let x = cost of IPod

\begin{array}{rcl}\text{Price} & = & \text{Cost + Markup}\\299 & = & x + 0.40x\\& = & x(1 + 0.40)\\& = & 1.40x\\x  & = & \dfrac{299}{1.40}\\\\& = & \mathbf{213.57}\\\end{array}\\\text{The cost of the IPod is $\large \boxed{\mathbf{213.57}}$}

Check:

\begin{array}{rcl}299 & = & x + 0.40x\\299 & = & 213.57 + 0.40 \times 213.57\\299 & = & 213.57 + 85.43\\299 & = & 299.00\\\end{array}

I need help with this
Temka [501]

Answer:

X will equal 30 degrees

Step-by-step explanation:

X will equal 30 degrees due to the rule of corresponding angles and that l1 and l2 are parallel with a transversal intersecting the parallel lines.

The angle of X and the angle of 30 degrees are corresponding angles.

Corresponding angles are equal to each other.

So X will also be 30 degrees.

I hope this answer helped and have a great day!
