Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits, and Elderberry. To make a decision, they use a spinner divided into four colors. They spin it 60 times to check the fairness of their model and record the results in this table.
The relative frequency of the spinner landing on green is

The relative frequency of the spinner landing on blue is

The relative frequency of the spinner landing on yellow is

The relative frequency of the spinner landing on red is

Answers

Answer 1

Answer:

Step-by-step explanation:

The theoretical frequency would be 1/4, and if spun 60 times, 15/60.

The relative frequency is how many times it actually landed on each color.

So green is 6/60

Blue is 24/60

Yellow is 9/60

Red is 21/60

I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:

Green: 1/10

Blue: 4/10

Yellow: 3/20

Red: 7/20

Step-by-step explanation:

The table is completed below.

We can say that the relationship between the scale factor and the area of scaled copies is proportional.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

Using the formula for the area of a triangle:

Area = 1/2 x base x height

With a base of 3cm and height of 2cm, the area of the original triangle is:

Area = 1/2 x 3cm x 2cm = 3cm²

To find the area of the scaled triangles, we can use the scale factor to determine the corresponding dimensions, and then calculate the area using the same formula.

Scale factor Corresponding dimensions Area

1 3cm x 2cm 3cm²

2 6cm x 4cm 12cm²

5 15cm x 10cm 75cm²

s 3s cm x 2s cm 3s² cm²

Now,

To see if the relationship between the scale factor and the area of scaled copies is proportional, we can calculate the ratio of the area to the scale factor for each row of the table:

Scale factor Corresponding dimensions Area Ratio of area to scale factor

1 3cm x 2cm 3cm² 3/1 = 3

2 6cm x 4cm 12cm² 12/2 = 6

5 15cm x 10cm 75cm² 75/5 = 15

s 3s cm x 2s cm 3s² cm² (3s²)/s = 3s

In each case, the ratio of the area to the scale factor is constant, which means that the relationship between the scale factor and the area of scaled copies is indeed proportional.

Therefore,

We can say that the relationship between the scale factor and the area of scaled copies is proportional.

Answer:

Step-by-step explanation:

The total amount of money in Mr. Peralta's savings account is $360.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Mr. Peralta had $300 in his savings account in March.

By August, the value of the savings account had increased by 20%.

Let, 'x' be the total amount after an increase of 20%.

So, 120% of $300 is 'x'.

Therefore,

(120/100)×300 = x.

300×1.2 = x.

x = 360.

So, By august total money in his account is $360.

Answers

Answer:

4th street

Step-by-step explanation:

Sorry but I only have an anwser for the first one

The measure of the angle created by the car's turning is 105°

Step-by-step explanation:

Given : a car is traveling east on 4th Street and turns onto King Avenue heading northeast.

We have to calculate the measure of the angle created by the car's turning.

Since, car is travelling in east direction on 4th street that is from A to D as shown below in image by arrow.

Then at point B, the car turns toward King Avenue heading northeast. that is B to C as shown below in image

Since, we need to calculate the measure of the angle created by the car's turning that is measure of ∠ABC.

AD is a straight line, thus measure of any angle at line segment AD is 180° as angles on one side of a straight line always add to 180 degrees

Therefore, at B,

∠ABC + ∠CBD = 180°

Aldo given , ∠CBD = 75°

Thus, the measure of ∠ABC is ,

⇒ ∠ABC = 180° -∠CBD

⇒ ∠ABC = 180° - 75°

⇒ ∠ABC = 105°

Thus, the measure of the angle created by the car's turning is 105°

Answer:

y=-1/3x+8

Step-by-step explanation:

There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

If the cafeteria has 80 customers on Tuesday, which prediction for Tuesday is NOT supported by the data in the table?
Pls answer ASAP

Answers

Answer:C

First you need to add up everything to find out the amount of costumers more Monday. You will get 40. Then you would have to multiply 40 by 2 to get 80 which is the total amount of costumers for Tuesday. This means that you have to double the amount of everything on the table to find out how much of each item was sold. The questions says which is NOT supported by the table. When you do the math you see that everything is accurate except C because the number of apple juice sold on Tuesday is 22 and the number of cranberry juice sold on Tuesday is 14. 22 is not 6 times more than 14 which makes C the correct answer.
