Penny is making a model of a Ferris wheel that is 60 feet tall. The model is 15 inches tall. Penny is also
making a model of the sky needle ride that is 100 feet tall using the same scale. How tall is the model of
the sky needle?

Answers

The model of the sky needle will be 20 inches tall as the scale factor is 4.

Since the Ferris wheel model is in feet and inches, bring both measurements to inches, then divide the total height of the Ferris wheel by the height of the model, then you multiply the height of the sky needle ride by the quotient of the height of the Ferris wheel and the model of the Ferris wheel to get 7 inches

Write the equation of the line in fully simplified slope-intercept form.

Answers

Answer:

-1x+8

Step-by-step explanation:Finding Slope:

If you pick a point on the line and see the height difference and distance of the next point (from left to right) you can find the slope. You must go down 1 (-1) and over 1 which gives this line a slope of -1/1 which equals -1.

Finding y-intercept:

Next we find the y-intercept which is much easier. Find what point on the y-axis (vertical bold line) the line passes. It passes at 8 so the y-intercept is 8.

Making Equation:

Now to make the equation we multiply the slope with x and add the y-intercept.

Final Equation:

-1x+8

The equation is y = -1x +8 with the y intercept being 8 and your slope being a -1

Answers

Answer:

Step-by-step explanation: don't know

M= -1

Explanation:
Step 1: bring -8 to the left since it is less than 10. It would now be 18+8m= -10.

Step 2: you would then move 8 to the right side since you want them to be equal on both sides. it would now be 18= -18m

Step 3: Finally, you divide -18 since you want to find m;you would need to separate them

Answer is m= -1

The ages of John and Sam are 47.34 and 17.66 years respectively.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, John’s age is 12 more than 2 times Sam’s age. The sum of their ages is 65.

Let, The age of Sam be 'x'.

Therefore, 2x + 12 + x = 65.

3x = 53.

x = 17.66.

So, Sam is 17.66 years old and john is (65 - 17.66) = 47.34 years old.

Answers

Answer: 66 yd

Explanation: It might seem like a very difficult shape to find the area, but it is actually really simple. All you have to do is split this shape in multiple squares, then find each area of each square, then add up all the square's area to get the total area of the shape.

Notice: Please take a look at the image I included to see how I divided the shape.

Step 1.) Since the shape is in a weird shape that doesn't allow us to find the area by normal means, we will split it in workable shapes. In this case, splitting it in 3 rectangles is best option (see image below).

Step 2.) Find the dimensions of each rectangle you split. Since we have new shapes, let us find the dimensions of each shape now.

Notice: Some sides of the shapes are split in half, to find the total length of a side we just add up the splits of the side. In this example our length's of the Rectangle 1 and 3 where split by 2 and 5 yards.

Rectangle 1: Length: 7yd; Width: 4yd

Rectangle 2: Length: 2yd; Width: 5yd

Rectangle 3: Length: 7yd; Width: 4yd

Step 3.) With the new dimensions of each shape, apply the correct formula for the area of each rectangle to find the area of each rectangle.

Area = Length x Width

A= L x W

Rectangle 1: Area = 28

A = L x W

A = (7) x (4)

A = 28

Rectangle 2: Area = 10

A = L x W

A = (2) x (5)

A = 10

Rectangle 3: Area = 28

A = L x W

A = (7) x (4)

A = 28

Final Step 4.) Now that we have the area of each individual rectangle, let us combine all the areas to find the total area of the shape.

Rectangle 1 + Rectangle 2 + Rectangle 3 = 66

28+10+28 = 66

Note: If you have any questions please let me know. If not, I hope this helped. Your very welcome :-)

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?

Answers

5,
3 is 1/3 of 9, meaning the probability of picking up a quarter is 1/3, if he finds 15 more,
15/3 is 5.

5 coins should be quarters

Answer: 5 coins

Step-by-step explanation:

Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or $\frac{3}{9}$, were quarters.

Simplifying this fraction, we get $\frac{1}{3}$ of the coins found in the car were quarters.

If Frank finds 15 more coins on the ground at the same ratio, then $\bold{\frac{1}{3}}$ of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find $\bold{\frac{1}{3}}$ of 15:

$\large \frac{1}{3} \times 15 = 5$

Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.
