Out of 449 applicants for a job, 253 have over 5 years of experience and 62 have over 5 years of experience and have a graduate degree. Step 1 of 2 : What is the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience
Answer:
The probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 24.50%.
Step-by-step explanation:
Given that out of 449 applicants for a job, 253 have over 5 years of experience and 62 have over 5 years of experience and have a graduate degree, to determine what is the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, the following calculation must be performed:
253 = 100
62 = X
62 x 100/253 = X
6,200 / 253 = X
24.50 = X
Therefore, the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 24.50%.
Solve for x , look at image above
Answer: x=16
Step-by-step explanation:
This problem can be solved by using proportions. We can see the figure as 2 triangles. One is ΔAED and another is ΔACB.
[tex]\frac{x}{8} =\frac{x+6}{11}[/tex] [cross multiply]
[tex]11x=8(x+6)[/tex] [distribute]
[tex]11x=8x+48[/tex] [subtract both sides by 8x]
[tex]3x=48[/tex] [divide both sides by 3]
[tex]x=16[/tex]
We know that x=16.

A company sells widgets. The amount of profit, y, mar by the company, is related to the selling price of each widget, x, by the given equation. using this equation, find out the maximum amount of profit the company can make, to the nearest dollar. y=-2x^2 + 105x - 859
Answer:
$522.12
Step-by-step explanation:
We can find this by x=-b/(2a) where a = -2 and b = 105:
x = -105/(2)(-2)
x= -105/-4
x= 105/4
We put this value of "x" into the original formula to find out the value of "y"
y = -2x^2 + 105x - 859
y = (-2)(105/4)^2 + 105(105/4) - 859
y = -1378.13 + 2756.25 - 859
y = 522.12
Therefore, the maximum profit would be $522.12

The sum of 100 consecutive interger from 1 to 100
Answer:
5050
Step-by-step explanation:
Ace here!
So, you could go through and add up everything but that takes a while, and there's a much easier way to do this. Let's write a rough sample of the numbers.
1, 2, 3, 4, 5....96, 97, 98, 99, 100.
Now, let's look at these numbers. Notice how if we add the two numbers on the leftmost and the rightmost, we get 101 (1+100). Now, we do 1 from the left added on to one from the right, and get 101(2+99). Then, we can follow that pattern and do 3+98=101, 4+97=101, and as long as we follow that pattern, we keep getting 101 as our answer.
Now, if we keep going with this, eventually we will get to 48+53, 49+52, 50+51.
If we supposedly counted all these pairs, we would find we have 50 pairs. But a quick way to check is to just divide 100 by 2 (100/2) and we get 50.
Now, we have 50 pairs that add up to 101. So, that would be 101 added to itself 50 times, which is just multiplication. 101 × 50 which is 5050.
I hope this helped. Let me know if you have any questions.

Two planes travel in opposite directions from the same airport. The
first plane travels at a speed of 320 mph, and the second plane’s
speed is 1.5 times greater. What is the distance between the two
planes after 5 hours?
Answer:
4000 miles
Step-by-step explanation:
320x1.5=480
(320x5)+(480x5)=4000
4000 miles
Answer:
[tex]4,000\text{ miles}[/tex]
Step-by-step explanation:
Let's say that the two planes travel at point [tex]p[/tex]. Without loss of generality, let's say that the first plane travels left and the second plane travels right.
Distance is given by [tex]d=rt[/tex], where [tex]r[/tex] is rate or speed and [tex]t[/tex] is time.
If the first plane travels at a speed of 320 mph and the second plane travels 1.5 times this, the second plane must travel [tex]320\cdot 1.5=480[/tex] mph.
Using [tex]d=rt[/tex], the first plane must travel:
[tex]d=320\cdot 5=1600[/tex] miles
The second plane must travel:
[tex]d=480 \cdot 5=2400[/tex] miles
However, these are the planes' respective distances from point [tex]p[/tex]. Since they travelled in opposite directions, the total distance between them is equal to [tex]1600+2400=\boxed{4,000\text{ miles}}[/tex]

Answer:
x = 15
Step-by-step explanation:
Create a proportional relationship to solve for x
3/2 = x/10
Cross multiply
2x = 30
Divide both sides by 2
x = 15
Answer:
Step-by-step explanation:
10/(10 + 2) = x/(x + 3) Combine left denominator
10/12 = x/(x + 3) Cross multiply
10(x + 3) = 12*x Remove the brackets on the left
10x + 30 = 12x Subtract 10x from both sides
-10x -10x
30 = 2x Divide by 2
2x/2 = 30/2
x = 15

Which of the following equations represents a line that passes through the points ( − 3 , − 3 ) and (−2,0)?
y=3x+6
Use
y=mx+b
to calculate the equation of the line, where
m
represents the slope and
b
represents the y-intercept.
Slope is equal to the change in
y
over the change in
x
, or rise over run.
Graph the line of the equation 5x+2y=12 using its slope and y-intercept.
Answer:
Step-by-step explanation:
First you need to put the equation in slope intercept form.
y = mx + b (m = slope and b = y-intercept)
5x + 2y = 12 (subtract 5x)
2y = -5x + 12 (now you need to isolate y. Therefore, divide all by 2)
y = -5/2x + 6
Now you have your slope and y-intercept. Your y-intercept will be 6. So on the graph you need to begin at 6 on the y-axis (the line that goes up and down). Make your first point there. Your slope is the -5/2x. Slope is looked at as rise/run. This means from your point at 6, you will go down (down because it's negative. If it was a positive, you would go up, i.e rise) 5 units. Then you will go over to the right 2 units (to the right because it is positive. Only the top one will be negative.) Place your point once you have done that. Then draw a line between those two points.
(note that on my screenshot, the tiny squares do not equal 1 unit. The larger ones with the bunch of tiny squares inside equal 1 unit)

[tex]4 \to[/tex] Constant
Step-by-step explanation:
Given
[tex]3x + 2(x +2) + 4[/tex]
Required
Complete the statements
In 3x, x is the variable; so:
[tex]3 \to[/tex] Coefficient of x
In 2(x + 2), 2 is the variable so:
[tex](x+2)\to[/tex] Variable
4 stands alone. So, it is a constant
[tex]4 \to[/tex] Constant
Answer: In the first term, 3 is a coefficient
In the second term, (x + 2) is a factor
In the last term, 4 is a constant
Step-by-step explanation:
The 3 in the first term is multiplied by a variable, x. So it is a coefficient.
The (x + 2) in the second term is multiplied by 2. So, it is a factor.
The 4 in the last term is not multiplied by anything. It is a fixed value, so it is a constant.

7. Find the area of Circle Y
Answer:
a. About 263.08 m²
Step-by-step explanation:
First find the radius (r):
Area of sector = central angle/360 ×πr²
Area of sector = 85.5 m²
Central angle = 117°
Plug in the values into the equation
85.5 = 117/360 × π*r²
85.5 = 1.02 × r²
85.5 - 1.02 = r²
84.48 = r²
r = √84.48
r = 9.19 m
✔️Find the area of the circle
Area of the circle = πr²
Where,
r = 9.19
Plug in the value
Area = π*9.2²
Area = 265.326663 (this is close to 263.08 cm²)
Area therefore is about 263.08 cm².

use round up method to present the number 45.056 to nearest integer. If the number is 45.56, would the answer be the same ?
Answer:
45.056 = 45
45.56 = 46
Step-by-step explanation:
Given :
45.056 to nearest integer. If the number is 45.56
To round 45.056 to the nearest integer, we evaluate the value after the decimal point, if the value after the decimal point is greater Than or equal to 5, we round to 1 and add to the value immediately before the decimal point, if otherwose, we round to 0 ;
Therefore,
45.056 = 45 (nearest integer) ; 0 is less than 5
45.56 = 46 (nearest integer) ; round 5 to 1 and add to 5, to give 6

Answer:
Letter D
Step-by-step explanation:
hope it helps
Answer:
Your answer is D
Step-by-step explanation:
So when fliping over the x-axis the x stays and the y changes.
So A is wrong because it was fliped over the y-axis
So is B since it did flip over the x-axis but then went over the y-acis.
So you are left with C and D
C and D did go over the x-axis but when you look at the figure it is different
C figure is the same and when you reflect somthing over any axis it will not always be the same.
Your answer is D, the figure is a reflection over the x-axis and the figure is fliped

Which is the graph of the linear equality 2x-3y<12
Answer:
The graph below shows the answer to
2x - 3y < 12
Also shown as
-3y < -2x + 12
Step-by-step explanation:
You can rearrange the inequality by subtracting 2x from both sides to isolate the y.
You now have -3y < 12 -2x
which can be put into the standard linear equation form of
-3y < -2x + 12
Then you divide both sides by -3 to get singular value of y, which is something like
-3/-3y < -2/-3x + 12/-3
which is
y > 2/3x -4
Note: I switched direction of the inequality because you are dividing both sides by a negative value.

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 second-hand smoke. One of the many responsibilities of the OSH is to collect data on tobacco use. The following data show the percentage of adults in the United States who were users of tobacco from 2001 through 2011:
Year Percentage of Adults Who Smoke
1 22.9
2 21.7
3 21
4 20.3
5 20.3
6 19.9
7 19.4
8 20.7
9 20.7
10 19
11 18.8
What type of pattern exists in the data?
Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series.
One of OSH’s goals is to cut the percentage of U.S. adults who were users of tobacco to 12% or less within nine years of the last year of these data. Does your regression model suggest that OSH is on target to meet this goal?
Use your model to estimate the number of years that must pass after these data have been collected before OSH will achieve this goal.
