Find the slope of the equation that goes through:
(-4,-14) and (-10,6)

Answers

Hello.

In order to find the slope of the given line, we should use the slope formula:

[tex]\mathrm{\displaystyle\frac{y2-y1}{x2-x1}}[/tex]

y₂= the y-coordinate of the second point (6

y₁= the y-coordinate of the first point (-14)

x₂=the x-coordinate of the second point (-10)

x₁=the x-coordinate of the first point (-4)

Let's plug in the values and solve:

[tex]\mathrm{\displaystyle\frac{6-(-14)}{-10-(-4)}=\frac{6+14}{-10+4} =\frac{20}{-6} =-\frac{20}{6} =-\frac{10}{3} }[/tex]

A gym membership is offered in January for $39.00 per month. If you pay upfront for the year, you are given a 25% discount on the monthly cost. How much money do you save after a year by paying upfront rather than monthly?

Answers

Answer: $351

Step-by-step explanation:

We need to setup two equations:

If you're taking the monthly cost: y = 468x, where x is the number of months.

If you're paying upfront: y = 12(0.25(39))x = 117x, where x is the number of years

So in one year, you will save (468-117) = $351 by paying upfront.

A biologist hopes to estimate the proportion of alligators in Florida that are adult. When sampling alligators, the biologist computes the one-proportion Z-interval going from 0.67 to 0.74 at 99% confidence. The margin of error for a 95% confidence interval would be:_____.

Answers

Using the z-distribution, as we are working with a proportion, it is found that the margin of error for a 95% confidence interval would be of 0.0008.

What is a confidence interval of proportions?

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

Considering the 99% confidence interval, which has z = 2.575, the estimate and the sample size are given by:

[tex]\pi = \frac{0.67 + 0.74}{2} = 0.705[/tex]

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.74 - 0.705 = 2.575\sqrt{\frac{0.705(0.295)}{n}}[/tex]

[tex]0.035 = 2.575\sqrt{\frac{0.705(0.295)}{n}}[/tex]

[tex]0.035\sqrt{n} = 2.575\sqrt{0.705(0.295)}[/tex]

[tex]\sqrt{n} = \frac{2.575\sqrt{0.705(0.295)}}{0.035}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.705(0.295)}}{0.035}\right)^2[/tex]

[tex]n = 1126[/tex]

Hence, the margin of error is given by:

[tex]M = 1.96\sqrt{\frac{0.705(0.295)}{1126}} = 0.0008[/tex]

In preparation for a conference, Derek is setting up some stations where people can create their own name tags. He has 10 name tags and 18 pens, which he wants to distribute evenly among the name tag stations with none left over. What is the greatest number of name tag stations that Derek can set up?

Answers

Answer:

2

Step-by-step explanation:

Given that:

Number of name tags = 10

Number of pens = 18

to distribute evenly among the name tag stations with none left over ; we need to obtain the greatest common factors of both 10 and 18 to know the number of stations Derek can set up ;

Factors of :

10 : 1, 2, 5, 10

18 : 1, 2, 3, 6, 9, 18

The greatest common factor is 2.

Hence, Derek can setup 2 stations.

If there are 1,400 costumers in a given week, how many would you expect to prefer chocolate strawberry or vert berry mix?​

Answers

Answer:

770 customers

Step-by-step explanation:

Oooh I love these types of questions!

First we should add all of the numbers to find the total number of people so we can set up a proportion later.

70+36+46+40+8=200

Now that we've found the total, we need to find chocolate strawberry and vert berry, because the wording "or" would mean either. If the wording said "and" we would not have enough information to solve that.

Chocolate Strawberry is 70, and Very Berry is 40. Add that to get 110.

Now we have our needed numbers to make a proportion! This is because for each 200 people, we know that they'd want 110 Chocolate Strawberry or Very Berry.

So we would need to make a proportion for 1400.

110/200=x/1400

Cross multiply (or do that trick where you divide 1400 by 200 and then multiply 110 by that number, but cross-multiplying is a good habit)

110(1400)=200x

Simplify

154000=200x

Isolate the variable

154000=200x

/200        /200

770=x

And that would be your answer! If I made any errors, please tell me!

How to find the perimeter of the rectangle

perimeter of rectangle = 2(l + h)

P(l, h) = 2(l + h)

Since the perimeter = 2(4+5) = 18, then;

18 = 2(4 + h)

9 = 4 + h

h = 9 - 4

Answers

The probability of randomly selecting a red marble will be P=1/45

What is probability?

The probability is defined as the chances of happening of any event it is defined as the ratio of required outcomes to the total number.

Now here is the question, it is given that

Total marbles in the bag = 15

probability of randomly selecting a green marble =  [tex]\dfrac{1}{3}[/tex]

The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is   [tex]\dfrac{1}{15}[/tex]

So, the probability of randomly selecting a red marble will be the product of the two probabilities.

[tex]P= \dfrac{1}{3} \times \dfrac{1}{15}[/tex]

[tex]P=\dfrac{1}{45}[/tex]

Thus the probability of randomly selecting a red marble will be

[tex]P= \dfrac{1}{45}[/tex]

The new location of C would be (7,0)

Answer:

Third option: (0, 7)

Step-by-step explanation:

A reflection can be thought of as folding or "flipping" an object over the line of reflection.

• The original object is called the pre-image, and the reflection is called the image.

• The image is usually labeled using a prime symbol, such as A'B'C'.

• An object and its reflection have the same shape and size, but the figures face in opposite directions. The objects appear as if they are mirror reflections, with right and left reversed.

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed).

Label the points for the pre image:

Pre image

Point A: (0, -2)

Point B: (3, -7)

Point C: (0, -7)

And now we change the y-coordinates in the points into their opposites:

When reflected over the x-axis:

Ponit A (0, -2) changes to A' (0, 2)

Point B (3, -7) changes to B' (3, 7)

Point C (0, -7) changes to C' (0, 7)

New image:

A' (0, 2)

B' (3, 7)

C' (0, 7)

So the new image for vertex C, would be:

It is known that the point P(-9,18) belongs to the graph of the function y=k/x. Find k.

Answers

Answer:

[tex]k = (-162)[/tex].

Step-by-step explanation:

A point of the form [tex](x_{0},\, y_{0})[/tex] belongs to the graph of this function, [tex]y = k / x[/tex], if and only if the equation of this function holds after substituting in [tex]x = x_{0}[/tex] and [tex]y = y_{0}[/tex].

The question states that the point [tex](-9,\, 18)[/tex] belongs to the graph of this function. Thus, the equation of this function, [tex]y = k / x[/tex], should hold after substituting in [tex]x = (-9)[/tex] and [tex]y = 18[/tex]:

[tex]y = k / x[/tex].

[tex]18 = k / (-9)[/tex].

Solve this equation for the constant [tex]k[/tex]:

[tex]\begin{aligned}k &= 18 \times (-9) \\ &= (-162)\end{aligned}[/tex].

Thus, [tex]k = (-162)[/tex].

Answers

The higher the score, the greater the decrease will be, since the greater the value of the decreased percentage will be greater too.

Given that you've got a credit score of 750, and you miss one credit card payment, to determine if this will impact your credit score MORE or LESS than if your original score was 650, the following calculation must be performed:

Suppose that a non-payment reduces the value of the score by 5%.100 - 5 = 95750 x 0.95 = 712.5 (-37.5)650 x 0.95 = 617.5 (-32.5)
