Skis at a sports store near Snow Summit are on sale for $475. If the original price was $500,what discount rate(percent change) does this represent?

Answers

Answer: 5%

Step-by-step explanation:

Hi to answer this question, first we have to calculate the discount amount:

Original price - sale price

500-475 =25

Now, the original price (500) multiplied by the percent discount in decimal form (x) must be equal to the discount amount (25)

500x =25

Solving for x

x =25/500 =0.05

Multiply it by 100 to express in percentage form.

0.05 x 100 = 5%

What is the area and perimeter of the length is 1.5 m and a width being 0.25 m? Thank you if ur a helper!

Answers

Answer: The area is 0.375 and the perimeter is 3.5

Step-by-step explanation:

The formula to find the area of something is length x width. So you have to multiply 1.5 x 0.25 which equals 0.375.

The formula to find the perimeter of something is length + width + length + width. (basically you have to add up all of the sides). I'm assuming the shape is a rectangle which means 2 sides have a length of 1.5 and the other 2 sides have a width of 0.25. So that means you would have to add 1.5 + 1.5 + 0.25 + 0.25 which equals 3.5

Answer:

Below in bold.

Step-by-step explanation:

Perimeter = 2 * length + 2 * width

= 2*1.5 + 2*0.25

= 3 .5 m.

Area = length * width

= 1.5 * 0.25

= 0.375 m^2.

Answers

Answer:

Converse of the Pythagorean Theorem

The Pythagorean Theorem states that if a triangle is a right triangle, then, the sum of the squares of the lengths of the  legs is equal to the square of the length of the hypotenuse.

That is, if a and b are legs and c is the hypotenuse, then

a2 + b2  =  c2

The converse of the Pythagorean Theorem states that if a2 + b2  =  c2, then the triangle is a right triangle.

Step-by-step explanation:

Answer:

The Flower Garden is not in the shape of a right Δ

Step-by-step explanation:

~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~

Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;

a^2 + b^2 = c^2,

10^2 + 7^2 = 13^2,

100 + 49 = 169,

149 ≠ 169,

So the Flower Garden will not be in the shape of a right Δ

An initial population of 298 quail increases at an annual rate of 8%. Write an exponential function to model the quail population.

What will the approximate population be after 3 years?

Answers

Answer:

375 as the whole number and 375.4 as a decimal.

Step-by-step explanation:

number = 298(1.08)^n , where n is the number of years

so when n = 3

population = 298(1.08)^3 = appr 375

The approximate population be after 3 years is  375 as the whole number and 375.4 as a decimal.

Given that,

An initial population of 298 quail increases at an annual rate of 8%.

Based on the above information, the calculation is as follows:

Step-by-step explanation:

y = - 8 is the equation of a horizontal line parallel to the x- axis.

A perpendicular line must then be a vertical line parallel to the y- axis.

The equation of a vertical line is x = c

where c is the value of the x- coordinates it passes through.

A mathematics teacher wanted to see the correlation between test scores and

55 | 55
89 | 91
85 | 88
61 | 52
76 | 76
76 | 81
61 | 59

Answers

Answer:

The homework  grade, to the nearest integer, for a student with a test grade of 68 is 69.

Step-by-step explanation:

The general form of the linear regression equation is:

[tex]y=a+bx[/tex]

Here,

y = dependent variable = test grade

x = independent variable = homework grade

a = intercept

b = slope

Compute the value of a and b as follows:

[tex]a=\frac{\sum Y\cdot \sum X^{2}-\sum X\cdot\sum XY}{n\cdot \sum X^{2}-(\sum X)^{2}}\\\\=\frac{(592\times 44909)-(591\times45227)}{(8\times44909)-(591)^{2}}\\\\=-14.316[/tex]                [tex]b=\frac{n\cdot \sum XY-\sum X\cdot\sum Y}{n\cdot \sum X^{2}-(\sum X)^{2}}\\\\=\frac{(8\times 45227)-(591\592)}{(8\times44909)-(591)^{2}}\\\\=1.195[/tex]

The linear regression equation that represents the set of data is:

[tex]y=-14.316+1.195x[/tex]

Compute the value of x for y = 68 as follows:

[tex]y=-14.316+1.195x[/tex]

[tex]68=-14.316+1.195x\\1.195x=68+14.316\\1.195x=82.316\\x=68.884\\x\approx 69[/tex]

Thus, the homework  grade, to the nearest integer, for a student with a test grade of 68 is 69.

The linear regression equation which models the relationship between homework grade and test grade and the predicted homework grade are :

y = 1.20x - 14.32

Predicted, x = 69

Using technology, the linear model can be obtained using either excel or a linear regression calculator.

Using a linear regression calculator which gives the linear equation in the form :

y = bx + c

y = 1.20x - 14.32

y = Test grade ; x = homework grade

Slope, b = 1.20 ; intercept, c = - 14.32

Using the model equation obtained :

Test grade, y = 68

Homework grade, x

y = 1.20x - 14.32

68 = 1.20x - 14.32

68 + 14.32 = 1.20x

82.32 = 1.20x

x = (82.32 ÷ 1.20)

x = 68.6

x = 69 (nearest integer)

Therefore, the estimated homework grade for a test score of 68 is 69

You are choosing between two different cell phone plans. The first plan charges a rate of 24 cents per minute. The second plan charges a monthly fee of $39.95 plus 10 cents per minute. How many minutes would you have to use in a month in order for the second plan to be preferable?

Answers

Answer: 286 minutes

Step-by-step explanation:

x : # of months that has gone by

0.24x : cost of the 24 cent plan after "x" minutes

39.95 + 0.10x : cost of the 10 cent plan after "x" minutes

1. 39.95 + 0.10x > 0.24x

2. 39.95 > 0.24x - 0.10x

3. 39.95 > 0.14x

4. 285.36 > x

x must be AT LEAST 286 minutes for plan #2 (39.95 + 0.10x) to be a better deal

Answer:

286 minutes.

Step-by-step explanation:

Plan one: .24x

Plan two: 39.95 + .10x

When x = 286, the price of plan one is $68.64, which is higher than plan two which is $68.55. This makes the second plan preferable after 286 minutes of use.

What are the mean,mode, and range for this set of data? 5.1,3.7,3.1,4.3,7.2,4.3,2.5

Answers

Answer:

Mean: 4.3142

Mode: 4.3

Range: 4.1

Step-by-step explanation:

5.1 + 3.7 + 3.1 + 4.3 + 7.2 + 4.3 + 2.5 = 30.2

30.2 ÷ 7 = 4.3142

Answer:

Step-by-step explanation:

First step to finding the mean, is to add all of the numbers up.

5.1 + 3.7 + 3.1 + 4.3 + 7.2 + 4.3 +2.5 = 30.2

The next step is to divide the total against the amount of numbers in the sequence. Since there are 7 numbers in this sequence, you will divide 30.2 by 7.

30.2 / 7 = 4.3 (rounded to the nearest tenth)

The mean of the data set is 4.3

To find the mode, you will look for the number of the set that appears most frequently. I suggest putting the numbers in order of least to greatest, as this keeps them sorted and organized.

2.5, 3.1, 3.7, 4.3, 4.3, 5.1, and 7.2

Looking at these numbers, you can see that 4.3 pops up twice in the data set. This will be the mode, because it is the number that appears most frequently.

To find the range, you take the greatest number in the data set, and subtract it by the smallest.

7.2 - 2.5 = 4.7

That means that 4.7 is the range of the data set.
