You pick a card at random.
2 3 4 5
What is P(odd)?
Write your answer as a percentage.
Answers
Answer:
1/2-50%..?
Step-by-step explanation:
The probability of picking an odd numbered card is 50%.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, the numbers on cards are 2 3 4 5.
Number of favorable outcomes = 2
Total number of outcomes = 4
Probability of getting odd numbers = 2/4
= 0.5
= 0.5 ×100
= 50%
Therefore, the probability of picking an odd numbered card is 50%.

3x + 2(x + 2) + 4
In the first term, 3 is
In the second term, (x + 2) is
In the last term, 4 is
Answers
Answer:
[tex]3 \to[/tex] Coefficient of x
[tex](x+2)\to[/tex] Variable
[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.

Which is the graph of the linear equality 2x-3y<12
Answers
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.
Answers
Step 1
Given,
Slope is b0=0.2809
Intercept is b1=21.9945
Let y=the percentage of adults who smoke.
And x=year
Therefore, the regression equation is obtained as-
y=21.9945+0.28...
If the exercise ball has been filled with Nitrogen which has a density of 0.2 grams per cubic inches. Find the mass in grams.
Options
11,581.2 grams
12,370.6 grams
13,891.5 grams
15,156.3 grams
Answers
Answer:
m = 11581.2 grams
Step-by-step explanation:
Given that,
The density of the ball, d = 0.2 g/in³
The radius of the ball, r = 24 inches
We need to find the mass of the ball in grams.
The density of an object is hiven by :
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{m}{\dfrac{4}{3}\pi r^3}\\\\m=\dfrac{4}{3}\pi r^3\times d[/tex]
Put all the values,
[tex]m=\dfrac{4}{3}\pi \times 24^3\times 0.2\\\\m=11581.16\ g[/tex]
or
m = 11581.2 grams
Hence, the mass of the ball is 11581.2 grams.

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?
Answers
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]

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Define
Identify and set up
30° + 74° + x = 180°
Step 2: Solve for x
Add: 104° + x = 180°[Subtraction Property of Equality] Subtract 104° on both sides: x = 76°Answer:
x° = 76 °
Step-by-step explanation:
We know that sum of interior angles of triangle is 180 °.
74 ° + 30 ° + x° = 180 °
combine like terms
104 ° + x° = 180 °
subtract each side by 104°
x° + 104 ° - 104 ° = 180 ° - 104 °
x° = 76 °

Answers
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%.
