Answer: (0,-10)
Step-by-step explanation:
The equation of a line (a,b) and (c,d) is given by :-
[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]
From the given graph , the line is passing through (6,2) and (8,6) is given by :_
[tex](y-6)=\dfrac{6-2}{8-6}(x-8)\\\\\Rightarrow\ y-6=\dfrca{4}{2}(x-8)\\\\\Rightarrow\ y-6=2(x-8)\\\\\Rightarrow\ y=2(x-8)+6[/tex]
To find the y intercept put x =0 , we get
[tex]y=2(0-8)+6=-16+6=-10[/tex]
Hence, the y-intercept of the graph : (0,-10)

When "P" Dollars is invested at interest rate "i", compounded annually, for "t" tears, the investment grows to "A" dollars, where A=P(1+i)^t. When Sara enters 11th grade, her grandparents deposit $10,000 in a college savings account. Find the interest rate "i", if the $10,000 grows to $11,193.64 in two years.
Answers
11,193.64 = 10,000 (1 + i)^2
Divide each side by 10,000.
1.119364 = (1 + i)^2
Take the square root of both sides.
1.058 = 1 + i
Subtract 1
i = 0.58
Final answer:
The annual interest rate compounded annually that grows $10,000 to $11,193.64 in two years is approximately 5.882%.
Explanation:
To find the interest rate i if the $10,000 grows to $11,193.64 in two years, we can rearrange the compound interest formula to solve for i:
[tex]A = P(1 + i)^t[/tex]
Given:
A = $11,193.64
P = $10,000
t = 2
Rearranging the formula to solve for i, we get:
[tex](A / P) = (1 + i)^t[/tex] → (11,193.64 / 10,000) = (1 + i)²
Now we must solve for i:
1.119364 = (1 + i)² → i = [tex]\sqrt{(1.119364)}[/tex] - 1
Calculating the square root of 1.119364 and subtracting 1 gives us:
i ≈ 0.05882 or 5.882%
Therefore, the annual interest rate compounded is approximately 5.882%.

There are 8 people fishing at Lake Connor: 5 have fishing licenses, and 3 do not. An inspector chooses two of the people at random. What is the probability that the first person chosen has a license and the second one does not? Write your answer as a fraction in simplest form.
Answers
Answer:3/28
Step-by-step explanation:
The probability that the first person chosen has a license and the second one does not is 15/56
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Given that, there are 8 people fishing at lake 5 have fishing licenses, and 3 do not. An inspector chooses two of the people at random. we need to find the probability that the first person chosen has a license and the second one does not
Let us consider the possibility of the first person not having a license, which is:
3/7
Now, after a person has been chosen, there will be 7 people remaining. Assuming that the first person chosen did not have a license, there will be 2 people left in the group without a license.
So, the probability of choosing a person without a license the second time will be:
3/7
In probability, when two events occur together (the word "and" is used), multiplication is carried out.
Therefore, we multiply the two probabilities to get:
5/8 x 3/7 = 15/56
Hence, The probability of choosing two people without a license is 15/56

what is 5-2y=3x in standard form?
Answers
To write 5 - 2y = 3x in standard form, you rearrange it to Ax + By = C, resulting in the equation 3x - 2y = -5, which is in standard form as requested.
To write the equation 5 - 2y = 3x in standard form, you want to arrange it to Ax + By = C, where A, B, and C are integers, and A should not be negative. Here's how you can do it:
First, we will move the term involving x to the left side of the equation by subtracting 3x from both sides:3x - (5 - 2y) = 3x - 3xThis simplifies to:-3x + 2y = 5Finally, to keep A positive, if necessary, multiply the entire equation by -1:3x - 2y = -5Thus, the standard form of the equation is 3x - 2y = -5.

An ounce is 1/16 of a pound. How many ounces are in 8 3/4 pounds?
Answers
3/4=12/16
128+12=140
Answer: 140 ounces
I hope this helps.
There are 140 ounces are in 8 3/4 pounds.
Given that,
1 ounce = 1/16 pound
We can also write it as
1/16 pound = 1 ounce
Multiply 16 both sides we get,
1 pound = 16 ounces ......(i)
Therefore,
There are 16 ounces in 1 pound.
Now we can write [tex]8\frac{3}{4}[/tex] in simple fraction as,
= (8x4+3)/4
= 35/4
Now we can say that [tex]8\frac{3}{4}[/tex] pounds as 35/4 pound as both are same quantity
Now, multiply 35/4 both sides in equation (i) we get,
35/4 pound = (35/4)x16 ounces
= 140 ounces.
Hence,
[tex]8\frac{3}{4}[/tex] pounds = 140 ounces.

Describe t-test and explain how to interpret its results ?
Answers
The t-test is a statistical test used to compare the means of two samples. The t-score, which represents the standardised difference between group means, and the p-value, which gives the probability of observing the data given the null hypothesis, are key components of the t-test result interpretation. A small p-value (typically less than 0.05) typically leads to rejection of the null hypothesis.
Explanation:The t-test is a statistical measure used in hypothesis testing to analyze the difference between two sample means. Key to proper interpretation of its results is understanding the test statistic, otherwise known as the t-score, and the p-value.
The t-score is calculated by subtracting one measure from the other and dividing by the standard error to standardize the difference. A large absolute value of the t-score indicates a larger difference between the groups being compared. The t-distribution, which the t-score follows, depends on the sample size (n) and has n - 1 degrees of freedom.
The p-value, usually calculated using technology, is the probability that you would observe the given t-score (or one more extreme) if the null hypothesis was true. It corresponds to the combined area in both tails of the t-distribution. If the p-value is small (typically less than 0.05), this suggests the differences you observed are statistically significant, and you would reject the null hypothesis.
When comparing the results, note that 95 percent of all confidence intervals constructed in this way contain the true value of the population mean statistic.

Your high school freshman class consists of 760 students. In recent years only 4 out 7 students actually graduated in four years. Approximately how many of your classmates are expected to graduate in four years
Answers
To find out how many of the 760 students in the freshman class are expected to graduate in four years, we use the rate of 4 out of 7 students graduating. This calculation yields approximately 434 students expected to graduate.
To calculate the approximate number of students expected to graduate in four years from a freshman class of 760 students, given a historical graduation rate of 4 out of 7, we use a simple proportion calculation. We set up a proportion where 4 out of 7 students graduate, which can be written as 4/7 = x/760, where x represents the number of graduating students.
Calculating this, we get x = (4/7) times 760. To solve for x, multiply both sides of the equation by 760 to isolate x.
x = 760 imes (4/7) = 760 imes 0.57142857
Approximately x = 434
Therefore, we can expect that approximately 434 students in the freshman class will graduate in four years, based on the provided rate.
