Two angles in a triangle have measures of 62° and 15º.What is the measure of the third angle?
Answers
Answer:
103 degrees
Step-by-step explanation:
The angles in a triangle always add up to 180 degrees
so 62+15=77
180-77=103
hope it helps :)
Answer:
103º
Step-by-step explanation:
All angles of a triangle add up to 180º
This means:
62º + 15º + the third angle = 180º
Then you just solve:
180º - 77º = 103º

What is the payback period for Project A?
Answers
Answer:
3.17 YEARS
Step-by-step explanation:
Payback calculates the amount of time it takes to recover the amount invested in a project from it cumulative cash flows
Payback period = Amount invested / cash flow
Payback period for option A, Product A
Amount invested = –$221,117
Amount recovered in year 1 = –$221,117 + 27,200 = -193,917
Amount recovered in year 2 = -193,917 + 60,000 = -133,917
Amount recovered in year 3 = -133,917 + 60,000 = -73,917
Amount recovered in year 4 = -73,917 + 425,000 = 351,083
Payback period = 3 years + (73,917 / 425,000) = 3.17 years
Which equation represents the following table?
Answers
Answer:
y = 2x+4
Step-by-step explanation:
When we substitute the value of x in y =2x+4. The output of function is exactly like in the table shown.
x = 1 —> y = 2(1)+4 = 6
x = 3 —> y = 2(3)+4 = 10
x = 5 —> y = 2(5)+4 = 14
x = 7 —> y = 2(7)+4 = 18
x = 9 —> y = 2(9)+4 = 22
Since the output is exactly like in the table. Therefore, y = 2x+4 represents the following table.

Answers
Answer:
238 times
Step-by-step explanation:
Given
[tex]a = 175[/tex] -- first week
[tex]r = 16.5\%[/tex]--- growth per week
[tex]t = 2[/tex] --- time
Required
The number of times it was downloaded in 2 weeks
An exponential growth is represented as:
[tex]y = a(1 + r)^t[/tex]
So, we have:
[tex]y = 175 * (1 + 16.5\%)^2[/tex]
[tex]y = 175 * (1.165)^2[/tex]
[tex]y = 175 * 1.357225[/tex]
[tex]y = 237.514375[/tex]
[tex]y = 238[/tex] -- approximated

Can a person train to become better at holding their breath? An experiment was designed to find out. A group of 12 volunteers were randomly assigned to 1 of 2 groups. The 6 volunteers assigned to group 1 were given breath-holding exercises to perform for 2 weeks. The other group was not given any information about the experiment. At the end of the 2 weeks, all 12 volunteers were individually tested to determine how long they could hold their breath. Here are the data (in seconds):
Group 1: 90, 88, 70, 110, 75, 105
Group 2: 40, 48, 35, 50, 55, 62
The researcher would like to determine if these data provide convincing evidence that the true mean amount of time volunteers who were given training held their breath is greater than the true mean amount of time volunteers without training held their breath. The researcher tests H0: μ1 – μ2 = 0, Ha: μ1 – μ2 > 0, where μ1 = the true mean amount of time that volunteers who were given training held their breath and μ2 = the true mean amount of time that volunteers without training held their breath. The conditions for inference are met. The standardized test statistic is t = 5.44. What is the P-value of this test closest to?
Answer is A, 0
Answers
The null hypothesis may be significantly rejected. Choose A, 0, for the closest response.
What does "true mean" refer to?In statistics, the term "true mean" refers to the true mean of a population or set of data.
It is typically unknown; hence it is estimated using inferential statistics using a sample.
For group 1, s1²= 250.67
group 2, s2² = 96.27
t= 5.44 which is the difference of mean.
Given the data values:
Group 1: 90 88 70 110 75 105
Group 2: 40 48 35 50 55 62
For group 1, n1 = 6
group 2, n2 = 6
Given that H_o= u1 - u2 = 0
H_a = u1 - u2 > 0
To find the t-test about the difference, we would use the formula to solve.
The totals are displayed below:
x1 = 538
x2 = 290
(x1-x2) ² = 1253.3334
x2-x2= 0
(X2-x2) ² =481.3334
For group 1, s1²= 250.67
group 2, s2² = 96.27
t= 5.44 which is the difference of mean.

4×103 times what number is equal to 16×105?
Answers
Answer:4.077669903
Step-by-step explanation:
4×103 is 4.04 times the 16*105.
What is Algebra?Algebra is a branch of mathematics that deals with symbols or variables and uses arithmetic operations (+, –, ×, ÷) to find the unknown quantities represented by these variables.
Let us consider the number be 'x'.
So, 4*103 of x = 16*105
x= 16*105/4*103
x= 4*1.01
x= 4.04
Hence, the number is 4.04.

to help consumers assess the risks they are taking, the food and drug administration (FDA) publishes the amount of nicotine found in all commerical brands of ciagrettes. a new ciagrette has recently been marketed. the FDA tests on this ciagrette yielded mean nicotine content of 24.3 milligrams and standard deviation of 2.1 milligrams for a sample of 9 ciagrettes. construct a 99% confidence interval for the mean nicotine content of this brand of ciagrette.
Answers
Answer:
The 99% confidence interval for the mean nicotine content of this brand of cigarette is between 21.95 and 26.65 milligrams.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 9 - 1 = 8
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 8 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 3.3554
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 3.3554\frac{2.1}{\sqrt{9}} = 2.35[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 24.3 - 2.35 = 21.95 milligrams
The upper end of the interval is the sample mean added to M. So it is 24.3 + 2.35 = 26.65 milligrams
The 99% confidence interval for the mean nicotine content of this brand of cigarette is between 21.95 and 26.65 milligrams.
