Which point is a solution to the inequality?
O (-2, 1)
0 (-1,1)
0 (0, 1/2)
0 (3, 1/2)
Option D is correct, (3, 1/2) point is a solution to the inequality y <1/3x+1/2.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given expression is y < 1/3x+1/2
y less than one divided by three times of x plus one divided by two.
Now let us check by plugging each ordered pair.
Now plug in (-2, 1)
1<1/3(-2)+1/2
1<-2/3+1/2
1<-4+3/6
Is false.
Now plug in (-1, 1)
1<-1/3+1/2
Is false.
Now plug in (0, 1/2)
1/2 < 1/2
is false.
Now plug in (3, 1/2)
1/2 < 3(1/3) + 1/2
1/2 < 1 + 1/2 is true.
Hence, (3, 1/2) point is a solution to the inequality y < 1/3x+1/2.

Which table represents a nonlinear function? ASAP
Answer:
The second table, the table in the middle.
Step-by-step explanation:
Since the x-values of all the tables differ by 1, the difference between the y-values must be constant in order for the table to be linear. In second table, the different between the first and second y-value (from top to bottom) is 3, however the difference between the second and third and third and fourth values are 1.5, which is not constant. Therefore, the second table is nonlinear.

Which of the following is described by the notation AB || CD ?
A. Perpendicular lines
B. Intersecting lines
O C. Skew lines
D. Parallel lines
Answer:
D Parallel lines
Step-by-step explanation:
this is one of the easiest symbols there are.
2 little lines being perfectly parallel to each other. that symbolizes (surprise, surprise) that the two actually referenced lines are parallel.
The notation "AB || CD" represents parallel lines.
Explanation:
In geometry, parallel lines are lines that never intersect. They are always equidistant and maintain the same distance between each other at all points. The notation "AB || CD" indicates that line AB is parallel to line CD.
Perpendicular lines are lines that intersect at a 90-degree angle. The notation "AB || CD" does not represent perpendicular lines.
Intersecting lines are lines that cross or meet at a common point. The notation "AB || CD" does not represent intersecting lines.
Skew lines are lines that do not lie in the same plane and are neither parallel nor intersecting. The notation "AB || CD" does not represent skew lines.
Parallel lines are lines that do not intersect and maintain the same distance between each other at all points. The notation "AB || CD" explicitly indicates that line AB is parallel to line CD.

If you borrow $200 for 12 years at
an annual interest rate of 2%, how
much will you pay altogether?
Answer:
$48
Step-by-step explanation:
200 x .02 = 4 (This finds how much interest you pay per year.)
4 x 12 = 48 (This finds how much interest you pay altogether.)
If you borrow $200 for 12 years at an annual interest rate of 2%, then we have pay $248 altogether.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
If you borrow $200 for 12 years at an annual interest rate of 2%
We need to find 2% of 200.
Firstly we have to convert 2% to decimal number by dividing with 100.
2/100=0.02
Now we have to multiply 0.02 with 200
0.02×200=4
For a month it is four.
Now we are calculating for year
4×12=48
So now the interest amount is 48.
Now add 48 and 200
48+200
248
Hence, If you borrow $200 for 12 years at an annual interest rate of 2%, then we have pay $248 altogether.

The Centers for Disease Control and Prevention Office on Smoking and Health (OSH) is the lead federal agency responsible for comprehensive tobacco prevention and control. OSH was established in 1965 to reduce the death and disease caused by tobacco use and exposure to secondhand smoke. One of the many responsibilities of the OSH is to collect data on tobacco use. The following data show the percentage of U.S. adults who were users of tobacco for a recent 11-year period
Year Percentage of Adults Who Smoke
1 22.9
2 21.7
3 21
4 20.3

6 19.9

Use your model from part (b) to estimate the number of years that must pass after these data have been collected before OSH will achieve this goal. Round your answer to the nearest whole number.
years.
Answer:
1.) A negative linear pattern
2.) Y = - 0.298X1 + 22.241
3.) slope = - 0.298 ; intercept = 22.241
Kindly check explanation
Step-by-step explanation:
Fitting the time series data using technology, the regression equation obtained is :
Y = - 0.298X+ 22.241
Where ; y = percentage of adults who smoke
x = year
Comparing with the linear equation model :
y = b1x + b0
y = - 0.298x + 22.41
-0.298 = slope
22.41 = intercept
The mean squared error, MSE = 0.512
To achieve, percentage users of 12% or less :
y = 12
Y = - 0.298X+ 22.241
12 = - 0.298X + 22.241
12 - 22.241 = - 0.298X1
-10.241 = - 0.298X
X = 10.241 / 0.298
X = 34.365
X = 35 years
From the model OSHA is not on target to meet it's goal as it will take 35 - 11 = 24 years from the last year of the data to achieve a smoker percentage less Than 12%

The lengths of bolts in a batch are distributed normally with a mean of 3 cm and a standard
deviation of 0.04 cm.
What is the probability that a bolt has a length greater than 2.96 cm?
Answer:
0.8413 = 84.13% probability that a bolt has a length greater than 2.96 cm.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 3 cm and a standard deviation of 0.04 cm.
This means that [tex]\mu = 3, \sigma = 0.04[/tex]
What is the probability that a bolt has a length greater than 2.96 cm?
This is 1 subtracted by the p-value of Z when X = 2.96. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{2.96 - 3}{0.04}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a p-value of 0.1587.
1 - 0.1587 = 0.8413
0.8413 = 84.13% probability that a bolt has a length greater than 2.96 cm.

The total body surface area, or BSA, of a human is difficult to calculate. There are various models that estimate BSA based on a person's weight and height. One simpler model is BSA= wh 3600
where w = weight in kg and h = height in cm.
a. Using this model, estimate the height of a person who weighs 75 kg and whose BSA is 1.9.
Round your answer to the nearest cm.
h = _______ cm
b. Using this model, estimate the weight of a person who is 166 cm tall and whose BSA is 2.2.
Round your answer to the nearest kg.
w= _________kg
Answer:
173 cm
105 kg
Step-by-step explanation:
Given :
BSA= √wh /3600
where w = weight in kg and h = height in cm.
A.)
w = 75 kg ; BSA = 1.9 ; h =?
BSA= √wh /3600
1.9 = √75h /3600
Take the square of both sides
1.9² = 75h /3600
1.9² * 3600 = 75h
12996 = 75h
h = 12996 / 75
h = 173.28 cm
h = 173 cm
B.)
h = 166 ; BSA = 2.2
BSA= √wh /3600
2.2 = √w166 /3600
Take the square of both sides
2.2² = 166w /3600
2.2² * 3600 = 166w
17424 = 166w
w = 17424 / 166
w = 104.96 kg
w = 105 kg
Using the model given, we have that:
a) h = 173 cm.
b) w = 105 kg.
The BSA, for a person of weight w and height h, is given by:
[tex]BSA = \sqrt{\frac{wh}{3600}}[/tex]
Item a:
[tex]BSA = 1.9, w = 75[/tex], hence:
[tex]BSA = \sqrt{\frac{wh}{3600}}[/tex]
[tex]1.9 = \sqrt{\frac{75h}{3600}}[/tex]
[tex]\left(\sqrt{\frac{75h}{3600}}\right)^2 = 1.9^2[/tex]
[tex]\frac{75h}{3600} = 3.61[/tex]
[tex]h = \frac{3600(3.61)}{75}[/tex]
[tex]h = 173[/tex]
Hence:
h = 173 cm.
Item b:
[tex]BSA = 2.2, h = 166[/tex], hence:
[tex]BSA = \sqrt{\frac{wh}{3600}}[/tex]
[tex]2.2 = \sqrt{\frac{166w}{3600}}[/tex]
[tex]\left(\sqrt{\frac{166w}{3600}}\right)^2 = 2.2^2[/tex]
[tex]\frac{166w}{3600} = 4.84[/tex]
[tex]w = \frac{3600(4.84)}{166}[/tex]
[tex]w = 105[/tex]
Hence:
w = 105 kg.

Step-by-step explanation:
Filing for bankruptcy can damage a person's credit for many years. which is the correct answer would be an option (C).
What is bankruptcy?Bankruptcy is a legal procedure that is supervised by federal bankruptcy courts. It is intended to assist people and organizations in eliminating all or part of their debt or repaying a fraction of what they owe.
Bankruptcy status on your credit record may make it harder to obtain new credit after the bankruptcy has been discharged – at least until the information is removed from your credit report. Lenders will be wary of extending you new credit, and they may require you to accept a higher interest rate or less favorable conditions in order to do so.
Thus, filing for bankruptcy can damage a person's credit for many years.
