Takis Tortilla Chips Variety Pack 18 Count
what is the unit rate of the product

Answers

Answer:

About 42 cents

Step-by-step explanation:

What we know:

An 18-count variety pack of Taki's chips costs $7.49.

To find the unit rate divide 7.49 by 18, and round to the nearest cent.

7.49/18

Before we do that, what is 749/18?

749/18 = 41 11/18

Divide that by 100 to get your answer

41.61111/100 = 0.4161111, which rounds to 42 cents.

QUESTION 3 Let G and H be two events in a sample space. P(G) = 0.4, P(H) = x and P(G or H) = 0.7 3.1 For what value of x are G and H mutually exclusive? (2)​

Answers

For x = 0.33, the events G and H are mutually exclusive.

Here, we are given that-  

P(G) = 0.4

P(H) = x

and P(G or H) = 0.73

⇒ P(G∪H) = 0.73

Now, we know that-

P(G U H) = P(G) + P(H) - P(G ∩ H)

For any two events that are mutually exclusive, the probability that they occur at the same time is 0. Hence, if G and H are mutually exclusive, then P(G ∩ H) will be 0

⇒ 0.73 = 0.4 + x - 0

x = 0.73 - 0.4

x = 0.33

Thus, for x = 0.33, the events G and H are mutually exclusive.

What is complex number?"It is combination of a real number and an imaginary number.""The complex number is of the form of a + ib, where a, b are real numbers and i = [tex]\sqrt{-1}[/tex]"How to write complex number in trigonometric form?

A. [tex]2\sqrt{10}[/tex]
B. [tex]4\sqrt{10}[/tex]
C. 8
D. [tex]2\sqrt{34}[/tex]

Answers

Answer:

A

Step-by-step explanation:

From looking at the graph, you can see that the center point of the circle is at (5, -3), so to figure out the diameter, you need to find the distance of that line ( y = - 3 ) that the circle is on. The diameter is about 6 point something which in the square root form can be represented by √36.

After knowing the diameter is about 6, choice C can be eliminated.

2√10 = √40

4√10 = √160

2√34 = √136

After expanding the square root, we can know that the closest option is A.

Check the picture below.

so we know the circle has that center and passes through (2 , -2), let's find its radius, keeping in mind that diameter = 2 * radius.

[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~5 - 2~~)^2 + (~~-3 - (-2)~~)^2} \implies r=\sqrt{(5 -2)^2 + (-3 +2)^2} \\\\\\ r=\sqrt{( 3 )^2 + ( -1 )^2} \implies r=\sqrt{ 9 + 1 } \implies r=\sqrt{ 10 }~\hfill \underset{diameter}{\stackrel{(2)(r)}{2\sqrt{10}}}[/tex]

standard deviation=0.6

we have to find the range in which at least 75% of the data will reside

1/k²=1-0.75

1/k²=0.25

k²=1/0.25=4

k=2

so, k=2

The range of values can be computed as mean±k(standard deviation).

Thus, the range in which at least 75% of the data will reside is

BD bisects angle ABC. Solve for x and find m angle ABC.
m angle ABD = 6x-8, m angle CBD = 3x + 4

Answers

Answer:

The value of x = 4

so

m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16

Step-by-step explanation:

We know that an angle bisector bisects the angle into two equivalent angles.

When BD bisects angle ABC, it forms two equivalent angles which are:

m∠ABDm∠CBD

such as

m∠ABD = m∠CBD

as

m ∠ABD = 6x-8

m∠CBD = 3x+4

so the equation becomes

m∠ABD = m∠CBD

6x-8 = 3x+4

6x - 3x = 4 + 8

3x = 12

Divide both sides by 3

x = 4

Thus, the value of x = 4

so

m ∠ABD = 6x-8 = 6(4)-8 = 24-8 = 16m∠CBD = 3x+4 = 3(4)+4 = 12+4 = 16

Say you have 47,964 blocks. For every 4 yellow blocks, you have 1 orange block. For every 4 orange blocks, you have 1 red block. For every 2 yellow blocks, you have 3 blue blocks. How many of each color block do you have?


Please show steps I'm horrible at multiple-ratio problems

Answers

Using proportions, the amounts you have of each block are given as follows:

Blue: 25,581.Yellow: 17,054Orange: 4,263.Red: 1,066

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

From the amounts given, you can create the following ratio:

Blue : Yellow : Orange : Red

6 : 4 : 1 : 0.25.

Hence the fractions corresponding to each color are given as follows:

Blue: 6/(6 + 4 + 1 + 0.25) = 6/11.25.Yellow: 4/11.25.Orange: 1/11.25.Red: 0.25/11.25.

Hence the number of blue blocks is found as follows:

6/11.25 x 47964 = 25,581.

The number of yellow blocks is given by:

4/11.25 x 47964 = 17,054.

The number of orange blocks is given by:

1/11.25 x 47964 = 4,263.

The number of red blocks is given by:

0.25/11.25 x 47964 = 1,066.
