Line p passes through points (18, 11) and (-17, 22). Line q passes through points (2, 37) and (-9, 72). Are line p and line q parallel or perpendicular?
The lines p and q are perpendicular lines.
According to the question,
We have the following information:
Line p passes through points (18, 11) and (-17, 22). Line q passes through points (2, 37) and (-9, 72).
We will find the slope of both the lines to check whether they are perpendicular or parallel. If their slope is equal then they are parallel and if their slope is not equal or inverse of the other one then they are perpendicular.
(Slope is denoted by m.)
m = (y2-y1)/(x2-x1)
For line p:
x1 = 18, y1 = 11, x2 = -17 and y2 = 22
m = (22-11)/(-17-18)
m = -11/35
For line q:
x1 = 2, y1 = 37, x2 = -9 and y2 = 72
m = (72-37)/(-9-2)
m = -35/11
Now, the slope is inverse.
Hence, the lines p and q are perpendicular lines.

A two-sided test is performed when we are interested in deviations _____________ from the hypothesized value.
When we are interested in deviations greater than or less than the hypothesized value, we do a two-sided test.
A two-tailed or two-sided test determines whether a sample is greater than or less than a specific range of values by using a two-sided critical area of distribution.
This test tests the null hypothesis. This test determines whether there is a statistically significant difference between the sample and population mean.
This test also determines whether a claim is true or not.
This test differs from a one-tailed test because one-tailed tests permit the potential for a one-directional effect. But the two-tailed tests examine the potential for two-directional (positive and negative directions) effects.

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. starting with 115 grams of a radioactive isotope, how much will be left after 3 half-lives?
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 115 grams of a radioactive isotope
If we start with 115g of the isotope, after one half-life the quantity will diminish to [tex]\frac{115g}{2} = 57.5[/tex] which is half the original quantity.
This can be written mathematically as: [tex]115g(\frac{1}{2})^{1}[/tex]
After the second half life: [tex]\frac{57.5g}{2} = 28.75 = \frac{115g}{4} = (115g)\frac{1}{2}^{2}[/tex]
After the third half life: [tex]\frac{28.75g}{2} = 14.37g = \frac{115g}{8} = (115g)(\frac{1}{2}) ^{3}[/tex]
But now we can see a pattern developing, because for each new half-life we are dividing the quantity by 2 to a power that increases as the number of half-lives.
Then we can take the original quantity and quickly compute for 6 half-lives:
[tex](115g)(\frac{1}{2})^{6} = (115g)(\frac{1}{64}) = \frac{115g}{64} = 1.79g[/tex]
The time it takes for the isotope to do this will depend on the isotope in question. For some it will be microsecond, and for others it will be years and decades. The isotope will typically decay to become another element or isotope.

There will be 5.41667 gallons of water in the bucket after 1 second according to the straight line present in graph.
The line passes through O(0, 0) and A(12, 5).
The slope of the line OA is given by :
Slope, m = ([tex]y_{2} - y_{1}[/tex])/([tex]x_{2} - x_{1}[/tex])
⇒ m = (5 - 0)/(12 - 0)
⇒ m = 5/12
The equation of the line passing through (0, 0) having slope = 5/12 is :
(y - 0) = (5/12)(x - 0)
⇒ y = 5x/12
After 1 second, the time t = 13 sec
Then, on substituting x = 13 in y = 5x/12, we can get the no. of gallons of water :

But it is a difficult problem for so many people. please write in your words what it is that you find difficult. Thanks :)
They ask for slope-intercept form of the problem. this form: y= mx + b
recall there is also point-slope form of y -y1 = m(x -x1)
They give us two points.
point P1 (15,40) in the form (x1,y1)
point P2(41,61) in the form (x2,y2)
Step1: find the slope
slope = m
m = (y2-y1) / (x2-x1)
m= (61-40) / (41-15)
m = 19 / 26
Step 2: now use the point-slope form to get the slope-intercept form. Any given point will work, I'll use P1
y - y1 = m(x -x1)
y - 40 = [tex]\frac{19}{26}[/tex](X - 15 )
use your algebra skillz to solve for "Y" ( get "Y" by itself )
y - 40 = [tex]\frac{19}{26}[/tex]X - [tex]\frac{19}{26}[/tex]*15
y - 40 = [tex]\frac{19}{26}[/tex]X - [tex]\frac{285}{26}[/tex]
y - 40 = [tex]\frac{19}{26}[/tex]X - 10[tex]\frac{25}{26}[/tex]
Y = [tex]\frac{19}{26}[/tex]X - 10[tex]\frac{25}{26}[/tex] + 40

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 11 people took the trip. She was able to purchase coach tickets for $260
and first class tickets for $1130. She used her total budget for airfare for the trip, which was $8080. How many first class tickets did she buy? How many coach tickets did she buy?
number of first class tickets bought
Main answer:
She bought 5 coach tickets and 6 first class tickets.
Step-by-step explanation:
Given:
Total tickets = 11
Let's First class tickets =f, Coach tickets = c.
Total tickets = f + c
f + c = 11
⇒ f = 11 - c → equation 1
Cost she used to purchase coach tickets = $260
Cost she used to purchase First class tickets = $1130
Total budget for airfare = $8080
260c + 1130f = 8080 → equation 2
Substitute equation 1 in equation 2;
260c + 1130(11-c) = 8080
260c + 12430 - 1130c = 8080
12430 - 8080 = 1130c- 260c
870c = 4350
c = 5 peoples
Now, Substitute c in equation 1;
f + c = 11
f = 11 - 5
f = 6 peoples
Hence, She bought 5 coach tickets and 6 first class tickets.

for a regression analysis, the value of r is 0.42. what is the value of the coefficient of nondetermination?
For a Regression Analysis that the value of R is 0.42, the value of the Coefficient of Non-Determination is 0.8236.
What is the Coefficient of Non-Determination?Coefficient of non-determination is the variation recorded in the dependent variable which is not counted by the changes in the explanatory variable. This is calculated by subtracting Coefficient of Determination from 1.
Coefficient of Non-Determination explains the amount of unexplained, or unaccounted for, variance among two variables, or among a set of variables (predictors) in an outcome variable.
The formula for the Coefficient of Non-Determination is 1 – R².
