graph the equation y = 1/2x-2 using 2 slope and y-intercept
Answers
for graph this equation,
we will calculate the point on this line,
the equation is
y = 1/2x-2
when x = 0
y = 1/2 (0) - 2
y = -2
thus, the point is (0, -2)
when x = 2
y = 1/2 (2) - 2
y = 1 - 2
y = -1
thus, the point is (2, -1)
when x = 4
y = 1/2(4) - 2
y = 2 - 2
y = 0
thus, the point is , (4, 0)
so we mark these points on the graph and join them to get a line on the graph.

The formula c=5p+215 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to p, the number of people attending the party.
Solve for p
If Allies parents are willing to spend $300 for her party, how many people can attend? Show your work.
Answers
300 = 5*(people comming) + 215.
300-215 = 5*P.
300-215= 85.
85/5=P
P=17.
17 people.
Answer:
17
Step-by-step explanation:
Since C represents the cost, and Allie's parents are willing to spend $300 for the party, our equation will now look like this:
300=5p+215
we are trying to find out how many people will able to attend
300=5p+215
-215 -215
---------------------
85 = 5p
divide by 5 on both sides to undo the multiplication (5p)
300=5p+215
-215 -215
---------------------
85 = 5p
÷5 = ÷5
--------------
17 = p
So, p (number of people attending) would be 17 :)

A stone is thrown into a pond. A circular ripple is spreading over the pond in such a way that the radius is increasing at the rate of 6.4 feet per second. Find a function, r(t), for theradius in terms oft. Find a function, A(r), for the area of the ripple in terms of r. Find (A or) (t).
Answers
SOLUTION
From the question, the r is increasing at the rate of 6.4 feet per seconds.
This means that the equation of the radius is
\(r=6.4\times t\)So the function for the radius, in terms of t becomes
\(r(t)=6.4t\)The Area A is given as
\(A=\pi r^2\)So, the function for the area in terms of r becomes
\(A(r)=\pi r^2\)Now, (A . r)t becomes
\(\begin{gathered} (A.r)t=\pi r^2,\text{ where r\lparen t\rparen = 6.4t, we have } \\ (A.r)t=\pi\times(6.4t)^2 \\ =40.96\pi t^2 \end{gathered}\)Hence the answer is
\((A.r)t=40.96\pi t^2\)The 3rd option is the answer

A 14-ft wide square footing on a clean, well graded medium sand with a unit weight of 102 pcf, is carrying a 250 kip load. The penetration resistance was measured to be 15. What is the expected settlement (in inches) at 6 feet below the surface if the groundwater table very far from the soil surface (ie, can be ignored)? q 8 Report your answer to two decimal places. Do not include units in your answer.
Answers
0.30 inches is the expected settlement at 6 feet below the surface.
A 14-ft wide square footing on a clean, well graded medium sand with a unit weight of 102 pcf, is carrying a 250 kip load.
The penetration resistance was measured to be 15.
We have,
P = 250, B = 14ft and N-value = 15.
9 = P/B² = (250 * 10³)/14² = 1275.51psf.
Since, B>4ft The expected settlement can be determined
S(in) = 49 met (Kip) ft² /N₅₀ *[B/(B + 1)]²
where, 9 = 1.28 Kip/ft²
N₆₀= N-value = 15
F = depth factor = 1
S(in) = (4 * 1.28)/ (15 * 1) [14/(14 + 1)]² = 0.30 in.
Therefore, the answer is 0.30 inches.

-6 is 6 units from 0.
6 is also 6 units away from 0.
-5 is 5 units from 0.
5 is also 5 units from 0.
The absolute value of -5 is 5.
The absolute value of -6 is 6.

Which of the following does the parameter u represent in a paired t procedure? the mean of a single variable in a population the difference between the means of two independent populations the standard deviation of the differences between paired observations the mean difference in the responses to the two groups within pairs of subjects in the entire population
Answers
The parameter u in a paired t procedure represents the mean difference in the responses to the two groups within pairs of subjects in the entire population.
This means that u captures the average change or effect observed when comparing the two related groups.
To elaborate further:
The parameter u represents a specific measure of interest in a paired t procedure. In a paired t procedure, the data consists of paired observations, where each observation is made on the same subject or item under different conditions.
The parameter u represents the mean difference between the paired observations for the entire population. It quantifies the average change or effect observed between the two groups being compared within the pairs of subjects. By estimating the value of u from a sample, we can make inferences about the population parameter and test hypotheses regarding the difference between the two groups.

Study found that a students GPA, G, is related to the number of hours worked each week, H, by the equation G equals -0.0007h^2 + 0.011h +3.01 estimate the number of hours worked each week for a student with a GPA of 2.57
A student with a GPA of 2.57 must have worked blank hours each week.
round to the nearest whole number as needed
Answers
A student with a GPA of 2.57 is estimated to have worked approximately 15 hours each week.
To estimate the number of hours worked each week for a student with a GPA of 2.57, we can substitute the GPA value into the equation G = -0.0007h^2 + 0.011h + 3.01, where G represents the GPA and h represents the number of hours worked.
By substituting G = 2.57 into the equation, we get:
2.57 = -0.0007h^2 + 0.011h + 3.01
To find the approximate number of hours worked, we can solve this quadratic equation. However, since we are asked to round the answer to the nearest whole number, we can use estimation techniques or software to find the value.
Using estimation or a quadratic solver, we find that the approximate number of hours worked each week for a student with a GPA of 2.57 is around 15 hours. Please note that this is an estimate based on the given equation and the specific GPA value. The actual number of hours worked may vary depending on various factors and individual circumstances.

Answers
The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, it is true that 95% of the coworkers fall within the interval (0.339, 0.501), and we can be 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%. However, it is false to say that there is a 95% chance that a randomly selected coworker has received the vaccine or that there is a 42% chance for a randomly selected coworker to have received the vaccine.
The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, we can determine which of the following statements are true:
a) 95% of the coworkers fall in the interval (0.339, 0.501).
This statement is true. The 95% confidence interval represents the range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that 95% of the coworkers fall within the interval (0.339, 0.501).
b) We are 95% confident that the proportion of coworkers who have received this year's flu vaccine is between 33.9% and 50.1%.
This statement is true. The 95% confidence interval (0.339, 0.501) provides us with a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that we are 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%.
c) There is a 95% chance that a randomly selected coworker has received the vaccine.
This statement is false. The 95% confidence interval does not represent a probability or chance for an individual coworker. It provides a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. It does not give information about the likelihood of an individual coworker receiving the vaccine.
d) There is a 42% chance that a randomly selected coworker has received the vaccine.
This statement is false. The 42% represents the proportion of coworkers in the survey who have received the flu vaccine, but it does not represent the chance or probability for a randomly selected coworker to have received the vaccine. The 42% is a point estimate, not a probability.
e) We are 95% confident that between 33.9% and 50.1% of the samples will have a proportion near 42%.
This statement is false. The confidence interval (0.339, 0.501) does not directly provide information about the proportion of samples that will have a proportion near 42%. The confidence interval represents the range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies, but it does not specifically address the proportion of samples near 42%.

Two polynomials P and D are given. Use either synthetic or long division to divide P(x) by D(x), and express P in the form P(x)=D(x)⋅Q(x)+R(x).P(x)=x4+3x3−17xD(x)=x−4
Answers
The polynomial P(x) can be expressed as P(x) = (x - 4)(x³ + 7).
To divide the polynomial P(x) = x⁴ + 3x³ - 17x by D(x) = x - 4, we can use long division.
Let's begin by setting up the long division: ________________________
x - 4 | x⁴ + 3x³ - 17x + 0
To start, we divide the leading term of P(x) by the leading term of D(x), which gives us (x⁴)/(x) = x³. We write this term above the division line.
x^3
________________________
x - 4 | x⁴ + 3x³ - 17x + 0
Next, we multiply D(x) = x - 4 by x³, which gives us x⁴ - 4x³. We write this below the dividend (x⁴ + 3x³ - 17x).
x^3
________________________
x - 4 | x⁴ + 3x³ - 17x + 0
x⁴ - 4x³
Now, we subtract the previous result from the dividend to get a new polynomial.
x³
________________________
x - 4 | x⁴ + 3x³ - 17x + 0
x⁴ - 4x³
________________________
7x³ - 17x
We bring down the next term from the dividend, which is -17x.

We have reached the end of the division process, and the remainder is 0. Therefore, the division of P(x) = x⁴ + 3x³ - 17x by D(x) = x - 4 gives us:
P(x) = D(x)×Q(x) + R(x)
P(x) = (x - 4)(x³ + 7) + 0
Simplifying the expression, we get:
P(x) = x⁴ + 7x - 4x³- 28
Thus, P(x) can be expressed as P(x) = (x - 4)(x³ + 7).

Answer:
65 degrees.
Step-by-step explanation:
To find the measure of angle C you have to add 90+25 and subtract it from 180. The reason for this is a triangle is 180 degrees, so to find the third angle you have to add and subtract. This gives you your answer of 65 degrees
Answer:
65 degrees
Step-by-step explanation:
There are 3 angles in a triangle, and they all add up to 180 degrees.
One angle is 25, and the other one is 90, because we can see a square in the corner, indicating 90 degrees.
If one angle is 25 and the other angle is 90, that makes 115 degrees together.
So we subtract 115 from 180 to get your answer, which is 65 degrees.
