Answers

Answer 1

Answer:

The mean will increase by 2.5

Step-by-step explanation:

The mean is just another word for the average of the data set. You can find this by adding all of the values and dividing by the number of values there are. (i.e 2+4+7+6+3+6+7 divided by 7). The original mean is 5. If you add 25, the average will increase to 7.5

Answers

1/4

If you have 4 different colors and probability of getting 1 color it would be 1/4

Answer:

2% chances

Step-by-step explanation:

The probability of spinning red is 2 out of 4 because since there is 4 colors and spinning a color twice it can't happen.

How do i know

1: Divide the number of color by the number of  outcomes

2: So since there are 4 colors and twice means 2.

3: 4 divided by 2 = 2% chances.

The cost of renting an apartment can be modeled by the function C(m)=900m+1400, where C(m) is the cost in dollars for m months of living in the apartment. State the meaning of the slope and y-intercept of this function with respect to the costs associated with renting the apartment.

Answers

Answer:

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Step-by-step explanation:

This function is linear, which means that it increases at a steady rate and has the following form:

[tex]y(x) = a*x + b[/tex]

Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

On November 1, the balance of a credit card account is $2,835.63. There was a payment of $230.00 made on

November 12 as well as a new purchase for $121.36. On November 25, a second payment of $25.00 was made. The

annual interest on the account is 17.65%. Determine the finance charge for the account using both the average daily

balance and the adjusted balance methods. Which method would be more advantageous to the cardholder? Justify

your reasoning. Answer in complete sentences.

Answers

Answer:

The adjusted balance is generally the most advantageous billing method for the cardholder since the financial charges are lower ($39.20 < $40.07). This happens because interest is only charged on the final monthly balance, and cardholders can decrease that balance during any day of the billing cycle.

Step-by-step explanation:

November 1: balance $2,835.63

November 12: $230 payment

November 12: $121.36 purchase

November 25: $25 payment

annual interest 17.65%

average daily  balance = {(11 x $2,835.63) + [13 x ($2,835.63 - $230 + $121.36)] +  [6 x ($2,835.63 - $230 + $121.36 - $25)]} 31 days = ($31,191.93 + $35,450.87 + $16,211.94) / 30 days = $82,854.74 / 30 days = $2,761.82

financial charge = ($2,761.82 x 30 x 17.65%) / 365 = $40.065 ≈ $40.07

adjusted balance = $2,835.63 - $230 + $121.36 - $25 = $2,701.99

financial charge = $2,701.99 x 17.65% x 30/365 = $39.197 ≈ $39.20

A. -5
B. -4
C. 0
D. 2
E.4

Answers

Answer:

C. 0

D.2

E.4

Step-by-step explanation:

To know which numbers are solutions to the inequality, we will follow the steps below:

-3x -3 < 6

add 3 to both-side of the inequality

-3x -3 + 3 <6+3

-3x < 9

Divide both-side of the inequality by -3

-3x/-3 >9/-3

whenever we are dividing both-side of inequality by a negative number, the inequality sign will change

x > -3

all values of x that are greater than -3 will satisfy the inequality

They are 0, 2 and 4

check the solution:

for x=0

Step-by-step explanation:

Given

cosΘ = [tex]\frac{7}{25}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]

The right triangle has sides 7, 24, 25 ← Pythagorean triplet

Find the lowest common denominator of the following fractions.5/n-2 and n+2/ n^2-4 n - 2 n2 - 4 (n - 2)(n2 - 4)

Answers

Answer:

(n-2)(n+2)

Step-by-step explanation:

The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.

 (n^2 -4) = (n -2)(n +2)

Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...

 (n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2

This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).

If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).

Answers

Answer:

The correct answer is y = -3x + 1.

Step-by-step Explanation:

First, you need to use the point slope formula to determine the slope. This is determined by the formula of the second y-coordinate (the y-coordinate in the second ordered pair) minus the first y-coordinate (the y-coordinate in the first ordered pair).

When subtracting the two values, you receive 7 - -5. You would use the KCC (keep, change, change) rule and keep positive 7, change the minus to addition, and turn negative 5 into positive 5. This gives you a value of 12.

Then, you use the same formula layout for the x-coordinates. Take the x-coordinate in the second ordered pair and subtract the x-coordinate in the first ordered pair to get -2 - 2 = -4.

Finally, to determine the slope, divide 12 and -4 to get -3.

Then, to get the y-intercept placed at the end, you will need to substitute the coordinate values from one of the ordered pairs into the equation y = -3x + b. I chose to use the first ordered pair, so:

-5 = -3(2) + b (Multiply the slope by x to earn the new value)

-5 = -6 + b (Add the -6 to the -5 to isolate the b)

1 = b (b = 1) (Learn that b = 1)

Your final equation will be y = -3x + 1.

Answer:

The equation is y = -3x + 1.

Step-by-step explanation:

First, you have to find the gradient of the equation using the formula :

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

Let (x1,y1) be (-2,7),

Let (x2,y2) be (2,-5),

[tex]m = \frac{ - 5 - 7}{2 - ( - 2)} [/tex]

[tex]m = \frac{ - 12}{4} [/tex]

[tex]m = - 3[/tex]

Next, we have to use the slope-form equation y = mx + b where m is gradient and b is constant. So we have to find the value of c by substituing any coordinates into the equation :

[tex]y = - 3x + b[/tex]

Let x = 2,

Let y = -5,

[tex] - 5 = - 3(2) + b[/tex]

[tex] - 5 = - 6 + b[/tex]

[tex]b = 6 - 5[/tex]

[tex]b = 1[/tex]

Answer:

Step-by-step explanation:

Circumference of circle =[tex]\pi \cdot d[/tex]

Where d is the diameter of circle

We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to [tex]\frac{360^{\circ}}{n^{\circ}}[/tex]

So, Number of sectors =  [tex]\frac{360^{\circ}}{n^{\circ}}[/tex]

The arc length of each sector is the circumference divided by the number of sectors

[tex]\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}[/tex]

Diameter d = 2r (r = radius)

At the Laika Boss Kennel Club, there are 15 dogs that are hairy or small, 2 dogs that are hairy and small, and 9 dogs that are small. How many dogs are hairy?

Answers

Answer:

8 hairy dogs

Step-by-step explanation:

There are 15 dogs that are hairy or small

2 that are hairy and small

9 that are small

small - ( hairy and small) =just small

9 -2 = 7 small only dogs

Take the total dogs minus the small dogs minus the small and hairy dogs to find the hairy dogs

15 - 7 - 2 =6

There are 6 hairy dogs

2 small and hairy dogs

7 small dogs

total 15 dogs

If we want the total of the hairy dogs

2 small and hairy + 6 hairy = 8 hairy dogs

You use a garden hose to fill a wading pool if the water rises 12 cm or seven minutes and you record the data point of (21,y) What is the value of Y?

Answers

Answer:

The rate of change at which the water level rise is 13/6 cm/minute.The slope of the line is 13/6.The value of y is 23, (12,23).

Step-by-step explanation:

In the question the water rises 13 cm every 6minutes. Taking x to represent the time in minutes and y to represent the rise in cm then, find the rise y in time x as;

6 minutes=13 cm

1 minute=?---------------------perform cross multiplication

(1*13)/6=13/6

Hence in 1 minute, the rise is 13/6 cm

Thus in 12 minutes, the rise will be ;

12 * 13/6 = 2*13= 26 cm

(x,y) will be (12,26)

Finding the slope of the line using point (6,13) and (x,y)

The rate of change at which the water level rises equals the slope of the line.This is the justification.

Identify the transformation that results in an image that's not congruent to the pre-image. Question 9 options: A) Rotation B) Translation C) Dilation D) Reflection

Answers

Answer:

C) Dilation

Step-by-step explanation:

Rotation is simply rotating an object, therefore, the size and shape remain the same.

Translation is moving the object across the plane, and again, the size and shape will stay the same.

Reflection is reflecting a shape across a certain line. It will still keep its size and shape.

However, dilation is enlarging or shrinking a shape. This means that the shape will change size, but not shape. A dilation of a shape will be similar, but not congruent, to it.
