Answer 1

Answer:

119°

Step-by-step explanation:

the angles of a triangle make 180° (so does a straight line) therefore

180 (triangle) = a + c + 51

to find c:

180 (straight line) = 112 + c

c = 180 - 112

c = 68°

now we have

180 (triangle) = a + 68 + 51

to find a:

a = 180 - (68 + 51)

a = 180 - 119

a = 61°

to find b:

180 (straight line) = 61 + b

b = 180 - 61

b = 119°

You have a data set with a Gas Price variable. It lists the price of a gallon of regular gasoline at a randomly selected 100 gas stations around the country in a particular week. You calculate a 95% confidence interval for the mean of Gas Price, and it turns out to be $2.43 plus or minus $0.16. Which of the following most closely reflects what you can conclude? a. If your sample size had been 400, and you had observed the same sample mean but a sample standard deviation twice as large as in your original sample, the 95% confidence interval would have been approximately $2.43 plus or minus $0.08. b. If your sample size had been 400 and you had obtained the same sample mean and sample standard deviation as in your original sample, the 95% confidence interval would have been approximately $2.43 plus or minus $0.08. c. If you had observed the same sample mean and sample size, but a sample standard deviation twice as large as the one you observed, the 95% confidence interval would have been approximately $2.43 plus or minus $0.24. d. If you had observed the same sample mean and sample size, but a sample standard deviation half as large as the one you observed, the 95% confidence interval would have been approximately $2.43 plus or minus $0.04.

Answer:

b. If your sample size had been 400 and you had obtained the same sample mean and sample standard deviation as in your original sample, the 95% confidence interval would have been approximately $2.43 plus or minus $0.08.

Step-by-step explanation:

Confidence interval:

A confidence interval is given by the sample mean plus minus the margin of error.

Margin of error:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which M is the margin of error, z is related to the confidence level(the higher the confidence level, the higher the value of Z), [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

This is important to note that the margin of error is inversely proportional to the square root of the size of the sample.

In this question, we have that:

95% confidence interval for the mean of Gas Price is of $2.43 plus or minus $0.16, with a sample of 100.

Option A:

Sample size of 400, which is four times the original, while the standard deviation is twice the original.

This means that the margin of error would be the same, as it would be multiplied by 2 in the numerator and divided by the square root of 4, that is, 2 in the denominator. So the interval would still be of $2.43 plus or minus $0.16, which means that option a. is wrong.

Option B:

Sample size of 400, which is four times the original, while the rest is the same.

The margin of error would be divided by the square root of 4, that is, 2, which means that it would be half of the original, and the interval would be $2.43 plus or minus $0.08, which means that option b. is correct.

Option C:

In this case, the margin of error will be doubled, since the standard deviation is double the original. So the confidence interval would be of $2.43 plus or minus $0.32, which means that option c. is wrong.

Option D:

In this case, the margin of error will be halved, since the standard deviation is half the original.  So the confidence interval would be of $2.43 plus or minus $0.08, which means that option d. is wrong.

Encontrar la media, mediana, moda y rango de los siguiente valores:

Answers

Answer:

La mediana es 79 la moda es 87 la media 87 y él rango es 26

Step-by-step explanation:

Espero te ayude ;)

The mode, median and the range are 87, 79 and 26 respectively

Given the data 84,91, 72,68,87, 78,65,87,79., we are to get the median, mode, and range of the data.

The mode is the number that occurs the most from the given data. Since 87 occurs twice, hence the mode is 87

The median is the number in the middle after arrangement. On arranging, we will have:

65, 68, 72, 78), 79, (84, 87, 87, 91

From the data, we can see that the median value is 79

Range  = Highest - lowest

Range = 91 - 65

Range = 26

Hence the range of the data is 26

from here we can tell that ?=2

2.) Let's start by dividing both sides by negative one

(x-2)/ -1= ?-x

simplify

-x+2= ?-x

Here we get ?= 2

3.)

Let's mulitply both sides by 5 to get

Simplify the expression below.
12a−8−5a+12

Answers

Step-by-step explanation:

Given

12a - 8 - 5a + 12

= 7a + 4

Hope it will help :)

Answer:

7a + 4

Step-by-step explanation:

First, let's rewrite this expression to combine like terms:

12a – 8 – 5a + 12  — I bolded the constants and underlined the expressions with variables

12a – 5a – 8 + 12  — it looks a little easier regrouped, doesn't it?

The last two terms are easy, right?

12 – 8 = 4  — simplify with subtraction

We'll focus on the first two terms now. Let's rewrite the terms with variables attached to make the subtraction easier:

a(12 – 5) = a(7) = 7a

We could also think of it this way: multiplication is just repeated addition.

12a = a + a + a + a + a + a + a + a + a + a + a + a (we just add a to itself 12 times)

5a = a + a + a + a + a (we just add a to itself 5 times)

Subtracting this expression would then look like this:

a + a + a + a + a + a + a + a + a + a + a + a – (a + a + a + a + a)

a + a + a + a + a + a + a + a + a + a + a + aaaaaa

Five of the a values will cancel out, and to show this, we can rewrite the expression once more, like this:

aa + aa + aa + aa + aa + a + a + a + a + a + a + a

The five a values cancel out and leave us with this:

a + a + a + a + a + a + a

How many a values are added together now? Seven of them, right? We add a to itself 7 times. We can then rewrite that expression as 7a.

Using the [12 – 8 = 4] expression from above, we add the 4 to the 7a to find our final answer: 7a + 4

I hope this helps increase your understanding of the concept! Have a great day!
