Dev is ordering a black bean burrito. He has 12
different ingredients to put with his black beans. How many different combinations of ingredients can he have in his burrito if he chooses exactly 4
different ingredients?

Answers

The answer is 3 combinations of ingredients.

Since he has 12 different options of ingredients and if he chooses 4 it’d mean to divide both numbers which equals 3.

5x-(x-18)=6-2(x+15) Help!

Answers

Answer:

Step-by-step explanation:

5x-(x-18)=6-2(x+15)

5x-x+18=6-2x-30

6x=-42

x=-7

The equivalent value of the expression is x = -7

Given data ,

Let the equation be represented as A

Now , the value of A is

5x - ( x - 18 ) = 6 - 2 ( x + 15 )

On simplifying the equation , we get

5x - ( x - 18 ) = 6 - 2 ( x + 15 )

So , the left hand side of the equation is equated to the right hand side by the value of 6 - 2 ( x + 15 )

Opening the parenthesis on both sides , we get

5x - x + 18 = 6 - 2x - 30

From the distributive property , we get

5x - x + 18 = 6 - 2x - 30

On further simplification , we get

4x + 18 = -2x - 24

Adding 2x on both sides , we get

6x + 18 = -24

Subtracting 18 on both sides , we get

6x = -24 - 18

6x = -42

Divide by 6 on both sides , we get

x = -42/6

x = -7

Therefore , the value of x = -7

Hence , the expression is x = -7

A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining to be paid. The graduate makes regular payments of $8,000 each year. The graph shows the sequence. f(x)=?​

Answers

Answer:

The equation is: [tex]f(x) = 52000 - 8000x[/tex]

Step-by-step explanation:

Given

Initial = 52000

Rate = 8000 each year

Required

Determine the equation of the graph

The equation can be determined using.

[tex]Amount = Initial - Rate* Years[/tex]

We used minus (-) because, the amount reduces as the student pays.

Let

[tex]y = Amount[/tex]

[tex]x = Years[/tex]

So, we have:

[tex]y = Initial - Rate * x[/tex]

Substitute values for Initial and Rate

[tex]y = 52000 - 8000 * x[/tex]

[tex]y = 52000 - 8000x[/tex]

Express as a function:

[tex]f(x) = 52000 - 8000x[/tex]

An automobile manufacturer claims that its jeep has a 59.8 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this jeep since it is believed that the jeep has an incorrect manufacturer's MPG rating. After testing 160 jeeps, they found a mean MPG of 59.7. Assume the standard deviation is known to be 1.3. A level of significance of 0.02 will be used. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.

Answers

Answer:

The value of the test statistic is -0.97

Step-by-step explanation:

This test is two tailed test.

Null and Alternative hypothesis is as follow

Null Hypothesis is used when it is assumed that there is no significant difference between the values.

Null Hypothesis = [tex]H_{0}[/tex] = [tex]\mu =[/tex] 59.8

The Alternative hypothesis is the alternative of the Null Hypothesis. It is an experimental technique that is used when it is assumed that there is some difference

Alternative Hypothesis = [tex]H_{a}[/tex] = [tex]\mu \neq[/tex] 59.8

Test statistcs is z

The value of test statistics can be calculated using the following formula

Test Statistics [tex]= (\bar x - \mu ) / \sigma / \sqrt n[/tex]

Test Statistics [tex]= (59.7-59.8) / 1.3 / \sqrt 160[/tex]

Test Statistics = -0.97

A store manager designs a new accounting system that will be cost effective if the mean monthly charge account balance is more than $50. A sample of 100 accounts is randomly selected. The sample mean balance is $56 and the sample standard deviation is $25.a.Find the t-statistic for a hypothesis test that is designed to answer the question.

Answers

Answer:

The t-statistic for a hypothesis test that is designed to answer the question is 2.4.

Step-by-step explanation:

Our test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the saple and n is the size of the sample.

A store manager designs a new accounting system that will be cost effective if the mean monthly charge account balance is more than $50.

This means that [tex]\mu = 50[/tex]

A sample of 100 accounts is randomly selected. The sample mean balance is $56 and the sample standard deviation is $25.

This means that [tex]X = 56, s = 25, n = 100[/tex]. So

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]

[tex]t = \frac{56 - 50}{\frac{25}{\sqrt{10}}[/tex]

[tex]t = \frac{6}{2.5}[/tex]

[tex]t = 2.4[/tex]

The t-statistic for a hypothesis test that is designed to answer the question is 2.4.

On a large college campus, the students are able to get free copies of the school newspaper,the local newspaper, and a national paper. Ninety percent of the students read at least one of thepapers, 40% read only the school newspaper, 20% read only the local paper, 5% read only thenational paper, and 2% read all three papers. Fifty percent read the school newspaper, and 5%read the school and national newspapers. A randomly selected student is asked whether he orshe reads the school, local, or national paper. Express each of the following events in setnotation and find the percentage of students represented by each.a The student does not read any paper.b. The student reads the local paper.c. The student reads exactly two papers.d. The student reads at least two papers.

Answers

Answer:

a) The percentage that the student does not read any paper is  10%  

b) The percentage that the student reads the local paper is 40%

c) the percentage that the student reads exactly two papers is 23%

d) the percentage that the student reads at least two papers is 25%

Step-by-step explanation:

Given the data in the question;

as illustrated in the Venn diagram below,

a)The student does not read any paper;

The percentage that the student does not read any paper will be;

100% - 90% = 10%

Therefore, The percentage that the student does not read any paper is  10%  

 

b) The percentage that the student reads the local paper;

from the Venn diagram below;

⇒ ( 20 + 15 + 3 + 2 )%    

= 40%

Therefore, The percentage that the student reads the local paper is 40%

c) The percentage that the student reads exactly two papers

⇒ ( 15 + 5 + 3 )%

= 23%

Therefore, the percentage that the student reads exactly two papers is 23%

d) The percentage that the student reads at least two papers;

⇒( 15 + 5 + 3 + 2 )%      

= 25%

Therefore, the percentage that the student reads at least two papers is 25%
