Express 6cm as a percentage of 7.5m
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%

In 2009 a survey of Internet usage found that 79 percent of adults age 18 years and older in the United States use the Internet. A broadband company believes that the percent is greater now than it was in 2009 and will conduct a survey. The company plans to construct a 98 percent confidence interval to estimate the current percent and wants the margin of error to be no more than 2.5 percentage points. Assuming that at least 79 percent of adults use the Internet, which of the following should be used to find the sample size (n) needed?
a. 1.96 â0.5/n = 0.025
b. 1.96 â0.5(0.5)/n = 0.25
c. 2.33 â0.5(0.5)/n =0.05
d. 2.33 â0.79(0.21)/n= 0.025
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]

Step-by-step explanation:
You have $16 and earn $0.50 for each cup of orange juice you sell. Write an equation that represents the
total amount A (in dollars) you have after selling cups of orange juice.
a) A = 16 + 0.5j
b) A = 16(0.5)
c) A = 16 -0.5j
0.5j
d) A=1
6-0.5j
Recall from Exercise 1-16 the experiment that investigated the effectiveness of a nicotine lozenge for subjects who wanted to quit smoking (Shiffman et al., 2002). Before the treatments began, subjects answered background questions, including how many cigarettes they smoked per day. Among the 1818 subjects in the study, the average was 22.0 cigarettes per day, and the standard deviation was 10.8 cigarettes per day. a. Identify the population and parameter of interest.
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.

justin has x nickels and y dimes. He has a minimum of 15 coins worth at most 1$ combined determine one possible soltuiion with a set of inequalities
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.
Which two expressions have the same value?
1. 23-82
2. 23 - (8 x 2)
3. (23 -8) x 2
Answer:
Any expression doesn't have the same value
Step-by-step explanation:
1. 23-82Subtract 82 from 23.
−59
2. 23 - (8 x 2)Simplify each term.
Multiply 8 by 2.
23−1⋅16
Multiply −1 by 16.
23−16
Subtract 16 from 23.
7
3. (23 -8) x 2Subtract 8 from 23.
15⋅2
Multiply 15 by 2.
