Find the area of a triangle with legs that are: 12 m, 15 m, and 9 m.
Answers
Answer:
108 meters squared or m^2
Step-by-step explanation:
* means multiply
15 is probably hypotenuse because its the longest
12 and 9 are probably base and height
area = base * height
area = 12 * 9
area = 108
Answer:
54m^2
Step-by-step explanation:
Suppose you are conducting a study about how the average US worker spends time over the course of a workday. You are interested in how much time workers spend per day on personal calls, emails, and social networking websites, as well as how much time they spend socializing with coworkers versus actually working.
The most recent census provides data for the entire population Of U.S. workers on variables such as travel time to work, time spent at work, and break time at work. The census, however, does not include data on the variables you are interested in, so you obtain a random sample of 82 full-time workers in the United States and ask about personal calls, e-mails, and so forth. You are curious about how your sample compares with the census, so you also ask the workers the same questions about work that are asked in the census.
Suppose the mean break time per day from the most recent census is 29.6 minutes, with a standard deviation of 16.0 minutes. Your sample of 82 U.S. workers provides a mean break time per day of 31.9 minutes with a sample standard deviation of 22.4 minutes.
Organize this information by completing the following table.
μ = _________ M= __________
σ= _________ s= ___________
σM = _______ sM = _________
Answers
Answer:
lol
Step-by-step explanation:
Now don't get us wrong – not all of these answers raise this excellent question
The value of [tex]\mu[/tex] = 29.6, M = 31.9, [tex]\sigma[/tex] = 16 , s = 22.4, [tex]\sigma_m[/tex] = 3.121, and [tex]\rm S_m[/tex] = 2.473.
It is given that the mean break time per day from the most recent census is 29.6 minutes with a standard deviation of 16 minutes.
It is required to organize the information in a table if the sample size is 82.
What is the margin of error(MOE)?It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
The formula for finding the MOE:
[tex]\rm MOE = Z_{score}\frac{s}{\sqrt[]{n} }[/tex]
Where is the z score at the confidence interval
s is the standard deviation
n is the number of samples.
We know:
[tex]\rm \sigma_m= \frac{\sigma^2}{n}[/tex]
We have,
[tex]\rm \sigma = 16 \ and \ n = 82[/tex]
[tex]\rm \sigma_m= \frac{16^2}{82}[/tex]
[tex]\rm \sigma_m= 3.121[/tex]
For [tex]\rm S_m[/tex]
[tex]\rm S_m = \frac{s}{\sqrt{n} }[/tex]
We have,
s = 22.4 and n = 82
[tex]\rm S_m = \frac{22.4}{\sqrt{82} }[/tex]
[tex]\rm S_m = 2.473[/tex]
Thus, the value of [tex]\mu[/tex] = 29.6, M = 31.9, [tex]\sigma[/tex] = 16 , s = 22.4, [tex]\sigma_m[/tex] = 3.121, and [tex]\rm S_m[/tex] = 2.473.

She is hoping to find sufficient evidence (a=0.05) that she will in fact win the election with more than 50% of the vote. The Statistics students test the following hypotheses, where p represents the proportion of all voters who will vote for Jemmy. which of the following statements would be true if a Type I error is made? (Select all that apply.)
a. Carrie ends up winning the election.
b. The students find a p-value less than 0.05 .
c. Carrie ends up losing the election.
d. The students find a p-value greater than 0.05

Answers
Answer:
b. The students find a p-value less than 0.05
c. Carrie ends up losing the election.
e. The students make the conclusion that Carrie does not have more than 50% of the vote.
Step-by-step explanation:
Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis.
Type I error is one in which we reject a true null hypothesis.
In the given scenario Type I error will be the one where students incorrectly estimates the p value and reject the null hypothesis when it was true. This error will result in losing the elections.

Find the sum of the infinite geometric series -27, -9, -3, … The ratio is /3 and u1 is -27
Answers
===================================================
Work Shown:
a = -27 = first term
r = 1/3 = common ratio, note how this is between -1 and 1
We start with -27 and multiply by 1/3 each time to get the next term
S = infinite sum
S = a/(1-r), which only works because -1 < r < 1 is true
S = -27/(1-1/3)
S = -27/(2/3)
S = (-27/1) divided by (2/3)
S = (-27/1) times (3/2)
S = (-27*3)/(1*2)
S = -81/2
As you generate and add up the terms of the sequence, the infinite sum slowly starts to approach -81/2 = -40.5; we'll never actually achieve this sum exactly. Think of it as approaching an asymptote.

Answers
It's a variable that deals with various labels, rather than the usual type of numeric variable you may be used to.
One example of a categorical variable is color. You could have red, green, blue, yellow, and orange as the five choices for your categorical variable. Each color is a label or category.
This is an example of a qualitative variable. We don't have any numeric data attached to color. They're simply names or labels. In contrast, a quantitative variable is something like a person's height since a number is attached here (more specifically its a continuous quantitative variable).

12p2 + 12pq +2p + 302 + 9
Answers
Answer:
Option (2)
Step-by-step explanation:
In this question we have to find the multiplication of the two expressions.
(2p + q)(-3q - 6p + 1)
= 2p(-3q - 6p + 1) + q(-3q - 6p + 1) [By distributive property]
= -6pq - 12p²+ 2p - 3q² - 6pq + q
= -12p² - (6pq + 6pq) - 3q² + 2p + q
= -12p² - 12pq + 2p - 3q² + q
Therefore, Option (2) will be the correct option.

Answers
Answer:
B,C,F
Step-by-step explanation:
A=L*W
P=2L+2W
P≤54
for A, 2L is already greater than 60
B works as 2W+2L in this case is 50
C states that perimeter is less than 54
D doesn't work, as 2L+2W=96
E doesn't work, see above, P=60
F, area=W*L
162/9=18
L=18
2L+2W=48, so F works
Answer:
trả lời:
B,C,F
Giải thích từng bước:
A = L * W
P = 2L + 2W
Trang ≤54
đối với A, 2L đã lớn hơn 60
B hoạt động như 2W + 2L trong trường hợp này là 50
C nói rằng chu vi nhỏ hơn 54
D không hoạt động, vì 2L + 2W = 96
E không hoạt động, xem ở trên, P = 60
F, diện tích =W*L
162/9=18
L =18
2L + 2W = 48, vì vậy F hoạt động
Simply this rational expression.
