Jim has 4 New York quarters, 3 Pennsylvania quarters, and 3 Virginia quarters in his pocket. What is the probability that he will get a Pennsylvania quarter followed by a Virginia quarter when he pulls two quarters out of his pocket?
1/10 or 10%.
First, you add up all the quarters to get the total amount of possibilities for the first quarter that gets pulled out.
4 NY + 3 PA + 3 VI = 10 total quarters.
So the total number of quarters becomes the denominator for the first probability, and the total number of PA quarters becomes the numerator.
So the probability of Jim pulling out a PA quarter first is 3/10.
Now you have to find the probability of drawing a VI quarter as the second quarter. Since it's known that Jim would have already pulled 1 quarter out, that means the total number of quarters he could draw is now 9, so 9 would be the denominator of the second probability. Since there should be 3 VI quarters left still in his pocket, the numerator for the second probability is 3.
So the probability of Jim pulling out a VI quarter second is 3/9.
Now to get the final probability of Jim pulling out both a PA quarter and a VI quarter in the correct order, all you have to do is multiply the two probabilities together and then you should get the probability of the correct quarters being pulled out inn the correct order.
The first probability, 3/10, times the second probability, 3/9 equals the total probability of 9/90, and it simplifies to 1/10 or 10%
the circle at eh top of a cylinder has a radius of 3.3 inches. the cylinder is 21 inches long. what is the volume of the cylinder?
Answer:
V =718.0866 in^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h
The radius is 3.3 and the height is 21
V = pi (3.3)^2 * 21
V = pi (10.89) (21)
V =pi 228.69
We can approximate pi by 3.14
V = 3.14(228.69)
V =718.0866 in^3

Which is larger, 3.2 x 10⁴ or 3.2 x 10⁵?
A. 3.2 x 104
B. 3.2 x 105
Answer:
3.2 x 10^5
Step-by-step explanation:
Scientific Notation
3.2 x 10^4 = 32000
3.2 x 10^5 = 320000
Final answer:
The number 3.2 x 10⁵ is larger than 3.2 x 10⁴ because it represents 320,000, compared to 32,000 which is represented by 3.2 x 10⁴. The exponent indicates the number of zeroes to follow the digit.
Explanation:
To determine which number is larger between 3.2 x 10⁴ and 3.2 x 10⁵, we need to understand the notation being used. In scientific notation, the number 10 raised to an exponent indicates how many places to move the decimal point. The larger the exponent, the larger the value.
For 3.2 x 10⁴, it means we have a 3.2 followed by 4 zeros, which is equal to 32,000. In contrast, 3.2 x 10⁵ means we have a 3.2 followed by 5 zeros, which is equal to 320,000. Clearly, 320,000 is larger than 32,000.
Thus, 3.2 x 10⁵ is larger than 3.2 x 10⁴.

When calculating total gross pay, you should ___
A) use only your hourly wage
B)use your hourly wage and tips
C) use only your tips
D) use your hourly wage and tips minus any deductions
Final answer:
To calculate total gross pay, sum the hourly wage and tips earned. This sum represents the entire earnings before any deductions such as tax or social security are taken into account. Thus, option b is correct.
Explanation:
When calculating total gross pay, you should use your hourly wage and tips. The gross pay represents the total amount earned before any deductions, such as taxes or social security, are subtracted. To find the total gross pay, simply add the total amount of earned hourly wage to the amount received from tips.
For instance, if an employee receives $15 per hour and works for 8 hours and also earns $40 in tips, their gross pay for that day would be:
Hourly wage: $15/hour x 8 hours = $120
Tips: $40
So, the total gross pay would be $120 + $40 = $160 for that day.
So, option b is correct.

Suppose that the heights of adult women in the United States are normally distributed with a mean of 65 inches and a standard deviation of 2.4 inches. Jennifer is taller than 70% of the population of U.S. women. How tall (in inches) is Jennifer? Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
Final answer:
Jennifer is 66.3 inches tall; this is calculated by finding the z-score for the 70th percentile and using it with the mean and standard deviation of the population.
Explanation:
To determine how tall Jennifer is, given that she is taller than 70% of the population of U.S. women, we need to find the corresponding z-score that reflects the 70th percentile of a normal distribution, and then use it to calculate her height.
Firstly, using a standard normal distribution table or a calculator, we find the z-score that corresponds to the 70th percentile. Generally, this z-score is around 0.5244 (this can vary slightly depending on the table or technology used to find it). Now we apply the formula for converting a z-score to the actual score using the population mean and standard deviation:
Height = mean + (z-score × standard deviation)
Plugging in the values for the population mean and standard deviation:
Height = 65 + (0.5244 × 2.4)
Height = 65 + 1.2586
Height = 66.2586 inches
After rounding, we conclude that Jennifer is 66.3 inches tall.
In the given case, Jennifer's height is approximately 66.3 inches.
To find Jennifer's height, we need to find the z-score corresponding to the 70th percentile (as she is taller than 70% of the population) and then use that z-score to find her height.
The z-score formula is:
[tex]\[ z = \frac{x - \mu}{\sigma} \][/tex]
First, we find the z-score corresponding to the 70th percentile using a standard normal distribution table or calculator.
A z-score of approximately \(0.5244\) corresponds to the 70th percentile.
Now, we can use the z-score formula to find Jennifer's height x
[tex]\[ 0.5244 = \frac{x - 65}{2.4} \][/tex]
[tex]\[ x \approx 66.2586 \][/tex]
Rounded to one decimal place, Jennifer's height is approximately 66.3 inches.
Here are the monthly charges for Jo's mobile phone.
Monthly charge £16
150 free minutes, then 13p per minute
150 free texts, then 15p per text
During one month, Jo makes 170 minutes of calls and sends 182 texts.
Work out the total charge for the month.
In details pls.
Answer:
£23.40 total for month.
Step-by-step explanation:
£16 for the monthly fee
170 mins - 150 = 20 extra mins = 20 × 13 = 260p or £2.60 for extra mins
182 mins - 150 = 32 extra mins = 32 × 15 = 480p or £4.80 for extra texts
16 + 2.60 + 4.80 = £23.40 total for month.

Find the solution to the following system using substitution or
elimination:
y = 2x – 1
y = 5x – 7
Answer:
x = 2
y = 3
Step-by-step explanation:
y = 2x – 1
y - 2x = -1
y = 5x – 7
y - 5x = -7
y - 2x = -1
y - 5x = -7
_________--
3x = 6
x = 6/3
x = 2
y = 2x – 1
y = 2(2) - 1
y = 4 - 1
y = 3
[tex]x=2\\y=3[/tex]
Substitution method:The substitution method is one approach to take into consideration. When one equation with one variable is solved, this expression is then used in the other equation. The substitution method entails solving for a single variable before inserting the solution into the other equation.Elimination method:To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are inequality.Solution - (Through substitution method)Given -
[tex]y=2x-1\\y=5x-7[/tex]
So, substitute [tex]y=2x-1[/tex] in [tex]y=5x-7[/tex].
[tex]y=5x-7\\2x-1=5x-7\\5x-2x-7+1=0\\3x-6=0\\3x=6\\x=\frac{6}{3} \\x=2[/tex]
Now, substitute [tex]x=2[/tex] in [tex]y=2x-1[/tex].
[tex]y=2x-1\\y=2(2)-1\\y=4-1\\y=3[/tex]
Therefore, [tex]x=2[/tex] and [tex]y=3[/tex].
