Answer:

Justin has 10 nickels and 5 dimes.

Step-by-step explanation:

Given that Justin has x nickels and y dimes, and he has a minimum of 15 coins worth at most $ 1 combined, to determine one possible solution the following calculation must be performed:

Nickel = 0.05

Dime = 0.10

15 x 0.05 + 0 x 0.1 = 0.75

14 x 0.05 + 1 x 0.1 = 0.80

13 x 0.05 + 2 x 0.1 = 0.85

12 x 0.05 + 3 x 0.1 = 0.90

11 x 0.05 + 4 x 0.1 = 0.95

10 x 0.05 + 5 x 0.1 = 1

So, Justin has 10 nickels and 5 dimes.

Solution :

The population of the interest is : All smokers

The parameters of the interest is : population mean number of the cigarettes per day.

Population of interest :

The population interest is defined as the group or the population form the sample from which the experimenter or the researcher draws results or the conclusion of the experiment.

In the context, the researcher wants to draw the results from all the smokers in the study, so the population of interest is the smokers.

Parameter of interest :

The parameters of interest is the set of all unknown numbers which describes the population from which the researcher wishes to test with the estimator.

In the context, the interest parameter is the mean or the average population number of the cigarettes per day.

Question:

You are making sandwiches for a large party. Each sandwich has two slices of bread, one slice of turkey, two slices of cheese, three slices of tomato and 5 slices of cucumber. How many sandwiches will you get from 10 slices of bread and 20 slices of cucumber? assuming you have plenty of everything

Answer:

4 sandwiches

Step-by-step explanation:

Given

1 Sandwich contains:

[tex]Bread = 2\ slices[/tex]

[tex]Turkey = 1\ slice[/tex]

[tex]Cheese = 2\ slices[/tex]

[tex]Tomato = 3\ slices[/tex]

[tex]Cucumber = 5\ slices[/tex]

Required

Number of sandwiches from 10 slices of bread and 20 slices of cucumber?

Since we are to assume that every other thing is in abundance, we will only consider the unit amount of bread and cucumber

[tex]Bread = 2\ slices[/tex]

[tex]Cucumber = 5\ slices[/tex]

Express as ratio

[tex]Bread : Cucumber = 2 : 5[/tex]

When the ratio is multiplied by 5, the slice of cucumber (25) will exceed the available slices (20).

So, we multiply by 4

[tex]Bread : Cucumber = 2*4 : 5*4[/tex]

[tex]Bread : Cucumber = 8 : 20[/tex]

This implies that:

8 slices of bread and 20 slices of cucumber are used

Hence:

4 sandwiches can be made

Answer:

[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]

Option d.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

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

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

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

79 percent of adults age 18 years and older in the United States use the Internet.

This means that [tex]\pi = 0.79[/tex]

98% confidence level

So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.33[/tex].

Which of the following should be used to find the sample size (n) needed?

We have to find n for which [tex]M = 0.025[/tex]

So the equation is:

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

[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]

Answer:

0.8%

Step-by-step explanation:

First, convert 7.5 m to cm.

There are 100 cm in one meter, so to convert this, multiply 7.5 by 100:

7.5(100)

= 750

So, there are 750 cm in 7.5 m.

To find the percent of 6 cm, divide 6 by 750, then multiply by 100:

(6/750) x 100

= 0.008 x 100

= 0.8

So, 6 cm as a percentage of 7.5 m is 0.8%

Step-by-step explanation:

Method 1: Set up a proportion

Set up an equation of the form:

\frac{\color{red}{\text{part}}}{\color{orange}{\text{whole}}}=

whole

part

​  

=

\,\,\frac{\color{blue}{\text{percent}}}{100}

100

percent

​  

Assign the variable xx to the unknown value:

\color{red}{x}=

x=

\,\,\color{red}{\text{part}}

part

The question asks what \textit{part}part of the total questions is 89%

Substitute the known values with the numbers given in the problem, and the unknown value with xx:

\frac{\color{red}{x}}{\color{orange}{200}}=

200

x

​  

=

\,\,\frac{\color{blue}{89}}{100}

100

89

​  

Solve for xx:

100\cdot\color{red}{x}=

100⋅x=

\,\,\color{orange}{200}\cdot\color{blue}{89}

200⋅89

Cross multiply

\frac{100x}{100}=

100

100x

​  

=

\,\,\frac{17800}{100}

100

17800

​  

Divide both sides by 100

178

Simplify

Method 2: Convert to decimal and multiply

{89}{100}=0.89

89%=  

100

89

​  

=0.89

Move decimal 2 places to the left

{Multiply result by the total:}

Multiply result by the total:
