Answer:
y = 1x + 7
Step-by-step explanation:
The equation formula for this scenario is y = mx + b
m = slope
b = y-intercept
To find the slope, pick two points. I picked (2,9) and (4,11).
Subtract 11 from 9, you'll get 2.
Subtract 4 from 2, you'll get 2.
2/2 equals 1. The slope (m) = 1
To find the b, y-intercept, plot the points on a graph and see if the linear line across the y-intercept. For this case, the y-intercept is 7.
The equation is: y = 1x + 7

in a parking lot with 200 cars, 50 cars are white, 30 cars are red, and 20 cars are silver. one car will be selected at random from the parking lot. if each car in the parking has only one color, which of the following cannot be the probability that the selected car will be green?
If each car in the parking has only one color , then the option which cannot be the probability that the selected car will be green is 0.6 , the correct option is (c) .
In the question ,
it is given that ,
total numbers of car in the parking lot = 200 cars
number of white cars = 50
number of red cars = 30
number of silver cars = 20
let the number of green cars be "x" ,
So , the number of green cars possible = 200 - 100 = 100
that means x ≤ 100 .
So , P(green) = x/200
Option(a)
p = 0.2 ,
So , x/200 = 0.2
x = 40
Option(b)
p = 0.1 ,
So , x/200 = 0.1
x = 20
Option(c)
p = 0.6 ,
So , x/200 = 0.6
x = 120
Option(d)
p = 0.5 ,
So , x/200 = 0.5
x = 100 ,
We can see that only option(c) gives the number of green cars as 120 , which is not possible .
Therefore , If each car in the parking has only one color , then the option which cannot be the probability that the selected car will be green is 0.6 , the correct option is (c) .

suppose a clothing store wants to determine the current percentage of customers who are over the age of forty. how many customers should the company survey in order to be 92% confident that the estimated (sample) proportion is within 5 percentage points of the true population proportion of customers who are over the age of forty? z0.16 z0.08 z0.04 z0.02 z0.01 0.994 1.405 1.751 2.054 2.326
The clothing store should survey at least 306 customers to be 92% confident that the estimated proportion within 5 percentage points of the true population proportion.
Define the term percentage?A fraction or proportion of a whole number, typically expressed as a number out of 100, is referred to as a percentage. It is much of the time indicated by the image "%".
To determine the sample size needed for this study, we need to use the following formula:
\(n = (Z^2 *p * q) / E^2\)
where:
n = sample size
Z = the Z-score associated with the desired confidence level (in this case, 92% corresponds to a Z-score of 1.75)
p = the estimated proportion of customers who are over the age of forty (we don't have a specific estimate, so we can use 0.5 as a conservative estimate)
q = 1 - p
E = the desired margin of error (in this case, 5 percentage points or 0.05)
Plugging in the values, we get:
n = (1.75² × 0.5 × 0.5) / 0.05²
n = 306.25
Therefore, the clothing store should survey at least 306 customers to be 92% confident that the estimated proportion of customers over the age of forty is within 5 percentage points of the true population proportion.

Mr kuldeep bought 7½ kg of and Mr Rajesh bought 5¾ kg of rice .who bought more rice and by how much.
Mr. Kuldeep bought more rice than Mr. Rajesh by 1¾ kg, or 1.75 kg more than Mr. Rajesh.
Mr. Kuldeep bought 7½ kg of rice and Mr. Rajesh bought 5¾ kg of rice. To find out who bought more rice and by how much, we need to compare the two quantities.
First, let's convert the mixed numbers into improper fractions:
7½ kg = (7 x 2 + 1)/2 = 15/2 kg
5¾ kg = (5 x 4 + 3)/4 = 23/4 kg
Now, let's compare the two fractions:
15/2 kg > 23/4 kg
Therefore, Mr. Kuldeep bought more rice than Mr. Rajesh.
To find out by how much, we need to subtract the smaller quantity from the larger one:
15/2 kg - 23/4 kg = (30 - 23)/4 kg = 7/4 kg
So, Mr. Kuldeep bought 7/4 kg or 1¾ kg more rice than Mr. Rajesh. In conclusion, Mr. Kuldeep bought more rice than Mr. Rajesh by 1¾ kg.

Prove using rules of inference 1. If the band could not play rock music or the refreshments were not delivered on time, then the New Year's party would have been canceled and Alicia would have been angry. If the party were canceled, then refunds would have had to be made. No refunds were made. Therefore the band could play rock music. 2. If you are not in the tennis tournament, you will not meet Ed. If you aren't in the tennis tournament or if you aren't in the play, you won't meet Kelly. You meet Kelly or you meet Ed. It is false that you are in the tennis tournament and in the play. Therefore, you are in the tennis tournament.
The main answer for the first argument is that we cannot prove that the band could play rock music based on the given premises and rules of inference.
1. Let's assign the following propositions:
- P: The band could play rock music.
- Q: The refreshments were delivered on time.
- R: The New Year's party was canceled.
- S: Alicia was angry.
- T: Refunds were made.
2. The given premises can be expressed as:
(¬P ∨ ¬Q) → (R ∧ S)
R → T
3. To prove that the band could play rock music (P), we need to derive it using valid rules of inference.
4. Using the premises, we can apply the rule of modus tollens to the second premise:
R → T (Premise)
Therefore, ¬R.

Find the equation that is parallel to 2x-y=7
Answer:
Below
Step-by-step explanation:
Lines that are parallel have the same slope, so all lines parallel to the one given have the same slope as it does. That slope value is most easily seen by transforming the given equation to slope-intercept form
(y = mx + b).
This line would be y = 2x -7, so the slope of any line parallel to it must have a slope value of 2.
Hi there.
\(= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =\)
First of all, we can't find the equation of the line that is parallel to the line we are provided with in this problem, which is \(\bf{2x-y=7}\), until we convert this equation into another form.
.
.
This form has a name, and it's called "\(\bf{Slope-Intercept\:Form}\).
.
.
So first, what we need to do is subtract 2x from both sides:
.
\(\bf{-y=7-2x}\)
.
It's not mandatory, but we can re-arrange the terms "7" and "-2x":
.
\(\bf{-y=-2x+7}\)
.
Last step: Divide both sides of the equation by -1:
.
\(\bf{y=2x-7}\)
.
"-2x" turned into "2x" because a negative number multiplied or divided by a negative number equals a positive number.
.
"7" turned into "-7" because a positive number multiplied or divided by a negative number equals a negative number.
.
Now, our equation is in "Slope-Intercept Form".
.
Remember that "Slope-Intercept Form" looks like this:
.
\(\bf{y=mx+b}\).
.
Now what we need to find is the equation of the line.
.
Let's skim through the provided information to see whether or not there's some information that can help us find the equation.
.
We're also provided with the fact that these lines, or equations, are parallel.
.
What that means is if two lines are parallel, their slopes are the same.
.
The slope of the line whose equation we just found is -2 (it's the number next to "x").
.
I hope that this helped clear your doubts; if any are left, please ask.

An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+a-27.2=180
2a-27.2=180
2a=207.2
a=103.6, and since b=a-27.2
b=76.4
So one angle is 103.6 degrees and the other is 76.4 degrees.

Which explicit formula describes the arithmetic
sequence {19, 14, 9, 4, ...}
Answer:
\(a_n=19+(n-1)(-5)\)
Step-by-step explanation:
The explicit formula for an arithmetic sequence is \(a_n=a_1+(n-1)d\) where \(a_n\) is the \(n\)th term and \(d\) is the common difference.
In this problem, we can see that the first term of the sequence is \(a_1=19\) and the common difference is \(d=-5\) since 5 is being subtracted each consecutive term.
Therefore, the explicit formula that describes the given arithmetic sequence is \(a_n=19+(n-1)(-5)\)
Answer:
option 2
Step-by-step explanation:
Let { a1, a2, a3, a4, ... } be the sequence.
now the 1st term (a1) will have a value when n = 1.
similarly, all the other terms will have the values given when we substitute their respective n values into the explicit formula or fibonacci sequence.
thus, check if the 1st term is 19 by using option 2
an = 19 + (n-1)(-5)
an = 19 + (n-1)(-5) ....n = 1
an = 19 + (n-1)(-5) ....n = 1 a1 = 19 + (1-1)(-5) = 19 + 0 = 19. so it's accurate so far.
next, check a2 where n = 2.
a2 = 19 + (2-1)(-5) = 19 - 5 = 14. ....
n = 3
a3 = 19 + (3-1)(-5) = 19 - 10 = 9.
hence the conclusion from this pattern.

Option B :)Mensa is an organization that allows people to join only if their Stanford-Binet IQs are in the top 2% of the population. Assume the population mean of Stanford-BinetIQs is 100, and the standard deviation is 15, and that the population is normally distributed. What is the probability that two randomly selected people both have Stanford-Binet IQs which qualify them for Mensa?
The probability that two randomly selected people both have Stanford-Binet IQs which qualify them for Mensa is approximately 0.000408, or 0.0408%.
To determine the probability that two randomly selected people both have Stanford-Binet IQs qualifying them for Mensa, we need to calculate the probability of an individual having an IQ in the top 2% and then multiply that probability by itself since we are interested in both individuals having qualifying IQs.
Since the population is assumed to be normally distributed with a mean of 100 and a standard deviation of 15, we can use the Z-score formula to find the probability.
First, we need to find the Z-score corresponding to the top 2% of the distribution. We can use a standard normal distribution table or a calculator to determine that the Z-score for the top 2% is approximately 2.05.
Next, we convert the Z-score into a probability using the standard normal distribution table or calculator. The probability of an individual having an IQ in the top 2% is given by the area under the curve to the right of the Z-score of 2.05.
P(Z > 2.05) ≈ 0.0202
Now, to find the probability that both individuals have qualifying IQs, we multiply the probabilities together.
P(both individuals qualify) = P(individual 1 qualifies) * P(individual 2 qualifies)
= 0.0202 * 0.0202
≈ 0.000408
Therefore, the probability that two randomly selected people both have Stanford-Binet IQs which qualify them for Mensa is approximately 0.000408, or 0.0408%.
