Answer:

C

Step-by-step explanation:

$4.29 for 12 oz

12 = 4.29

1 = ?

? = (1 * 4.29)/12 = 4.29/12 = 0.3575 is the lowest amongst others

5.29/14 = 0.3779

2.59/6 = 0.4317

2.89/8 = 0.3612

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.

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!

Answer:

x = 5.200

Step-by-step explanation:

Given equation is,

x³ - 4.6x² - 7.03x = -20.332

x³ - 4.6x² - 7.3x + 20.332 = 0

By graphing this equation with the help of a graphing calculator,

Solutions of the equation are the points where y = 0.

In other words, x intercepts are the solutions.

Solutions for the given equation are,

x = -2.3, 1.7 and 5.2

Therefore, solution for the given equation in the interval [4, 7] is x = 5.200

Step-by-step explanation:

simply use the formula as given in the image

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

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]

By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.

Percentage is a number or ratio expressed as a fraction of 100.

Here given that

Marilyn has two credit cards, D and E. Card D has a balance of $691. 64, and Card E has a balance of $1,014. 22. The minimum monthly payment on Card D is 3. 57% of the total balance, and the minimum monthly payment on Card E is 2. 51% of the total balance

So minimum balance of Card D is 3.57 Percentage  of $ 691.64

[tex]=3.54\times\frac{691.64}{100} =24.691548=24.69[/tex]

minimum balance of Card E is  2. 51 Percentage  of  $1,014. 22.

[tex]=2.51\times\frac{1014.22}{100} =25.456922=25.46[/tex]

Now we can see that minimum balance of Card E is 25.49-24.69=0.77 extra that on D

By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.

Answer:

Step-by-step explanation:

3 is 65 and 9 is 65 because they are alternate interior angles

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].

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.

A confidence interval of proportions is given by:

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

In which:

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]
