Find the nth term of this number sequence
1, 10, 19, 28, ...
Pls help
Answer:
9n - 8
Step-by-step explanation:
The sequence is arithmetic since the difference between consecutive terms is common
d = 10 - 1 = 19 - 10 = 28 - 19 = 9
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 1 and d = 9, thus
[tex]a_{n}[/tex] = 1 + 9(n - 1) = 1 + 9n - 9 = 9n - 8, hence
[tex]a_{n}[/tex] = 9n - 8
We are required to find the nth term of the sequence 1, 10, 19, 28,....
The nth term of the sequence 1, 10, 19, 28, is 9n - 8
Given:
1, 10, 19, 28,
First term, a = 1
Common difference, d = difference between consecutive terms
10 - 1 = 9
19 - 10 = 9
28 - 19 = 9
nth term = a + (n - 1)d
nth term = 1 + (n - 1)9
= 1 + 9n - 9
= 9n - 8
Therefore, nth term of the sequence 1, 10, 19, 28, is 9n - 8

The value of n in the equation is 1
Step-by-step explanation:
The equation is [tex]-\frac{1}{2}[/tex] (2n + 4) + 6 = -9 + 4(2n + 1)
At first we must do that:
1. Open the brackets in both sides
2. Add like terms
3. Solve to find n
L.H.S:
∵ [tex]-\frac{1}{2}[/tex] (2n + 4) + 6 = -n - 2 + 6
∴ [tex]-\frac{1}{2}[/tex] (2n + 4) + 6 = -n + 4
R.H.S:
∵ -9 + 4(2n + 1) = -9 + 8n + 4
∴ -9 + 4(2n + 1) = 8n - 5
∴ -n + 4 = 8n - 5
- Add 5 to both sides
∴ -n + 9 = 8n
- Add n to both sides
∴ 9 = 9n
- Divide both sides by 9
∴ n = 1
The value of n in the equation is 1

The capacity of the milk pitcher on the counter is 9/10 liter each one pitcher has3/8 of milk in it and the other pitcher has 5/12 of a liter milk in it much is there altogether?
Answer:
57/80L
Step-by-step explanation:
Given that the capacity (i.e maximum possible volume) of a pitcher is 9/10L
1st Pitcher is 3/8 full of milk
Hence Vol of milk in 1st pitcher = 9/10 x 3/8 = 27/80L
2nd Pitcher is 5/12 full of milk
Hence Vol of milk in 2nd pitcher = 9/10 x 5/12 = 3/8 = 30/80L
Total volume = 27/80 + 30/80 = 57/80L
Final answer:
Adding the milk from the two separate pitchers gives a total of 19/24 liters of milk together.
Explanation:
You are asking about a volume measurement related to liters, which indeed is a unit of capacity. One pitcher contains 3/8 of a liter of milk, and the other pitcher contains 5/12 of a liter. To find out how much milk is there altogether, we will simply add the volumes:
[tex]\(\frac{3}{8} + \frac{5}{12} = \frac{9}{24} + \frac{10}{24} = \frac{19}{24}\) liters[/tex]
To calculate this, we first find a common denominator, which is 24 (the least common multiple of 8 and 12). Then we convert each fraction to an equivalent fraction with a denominator of 24, before adding them together. So, the total amount of milk in both pitchers together is 19/24 liters.

this will equal 86 is the anwer to question u have asked
Answer:86
Step-by-step explanation:
Step 1:Put 2,332 the (dividend) in the brackets,(in the box)
The divisor is 27 ,so it's outside of the brackets or outside of the box
Step 2:What is 232 into 27 , the reason I skipped 2 and 3 because there smaller than 27. 232 into 27 is 8 because it's closest to 232 which is 216 because 27*8 equals 216. 8 is now on top of the bracket and now you subtract 232-216 which is 16.
Step 3:Bring down 2 ,because 2 is the last number left.
Now we have to figure out what goes into 162
6 goes into 162 because 27*6=162
Step 4:Subtract 162-162=0
We stop because there's no more to go into unless it was a different number than 162 then we would of brung down the 0 because there's no more numbers after 2 and the number would of been a decimal but there's no more to go into.
6 down goes above the bracket next to 8 now we have an answer of 86.
So the quotient/answer=86

Manuel took 2 2/5
hours to clean the den. He took 1 1/3
hours to clean the bathroom. How much longer did it take Manuelt
clean the den?
It took Manuel approximately 1.07 hours longer to clean the den compared to the bathroom. This was calculated by converting the mixed numbers to improper fractions and subtracting.
Explanation:In this problem, we are comparing the time it took Manuel to clean the den and bathroom. To do this, we need to subtract. Firstly, you need to convert the mixed numbers, 2 2/5 hours and 1 1/3 hours, into improper fractions for ease. This would be 12/5 hours and 4/3 hours respectively. Now we subtract 4/3 from 12/5. You can use the least common denominator (LCD) to make this easier: 12/5 (which is 2.4 in decimal) minus 4/3 (which is 1.33 in decimal) equals approximately 1.07 hours. It means Manuel took 1.07 hours(approximately) longer to clean the den compared to the bathroom.

The 40% of the department faculty have 5 or more years of service.
To calculate the percentage of department faculty with 5 or more years of service, we can divide the number of faculty with 5 or more years of service by the total number of faculty and multiply by 100%.
% with 5 or more years of service = (number with 5 or more years of service) / (total number of faculty) * 100%
From the histogram, we can see that there are 10 faculty with 5 or more years of service and a total of 25 faculty in the department. Therefore, the percentage of department faculty with 5 or more years of service is:
% with 5 or more years of service = (10 faculty) / (25 faculty) * 100%
% with 5 or more years of service = 40%
Therefore, 40% of the department faculty have 5 or more years of service.

A box contains 6 red balls, 7 yellow balls, and 2 green balls. All the balls are the same except for their color, Jaime picks a ball from the
box, records the color, then returns the ball to the box. He does this 3 times
What is the probability that all three balls that Jaime picked were red?
Answer:
The answer is 8/27
The probability that all three balls that Jaime picked were red is '0.064'
Now the box contains 6 red balls, 7 yellow balls, and 2 green balls
Thus the total number of balls in the box can be find by summing up all the balls in the box
Thus we get,
Total number of balls = 6 + 7 + 2 = 15 balls
Thus there are total of 15 balls in the box
Now Jamie picks a ball from the box, records the color, then returns the ball to the box.
Thus in the first try, the probability that the ball picked up is red:
Probability that the first ball picked is red = [tex]\frac{6}{15}[/tex]
where, '6' is the number of red balls
and '15' is the number of total balls in the box
Similarly as the ball picked up is again returned to the box the number of red balls and total number of balls won't change
Similarly probability that the second ball picked is red = [tex]\frac{6}{15}[/tex]
Similarly probability that the third ball picked is red = [tex]\frac{6}{15}[/tex]
Thus to find the combined probability we need to multiply all three probabilities
Thus probability that all three balls that Jaime picked were red is,
[tex]\frac{6}{15} *\frac{6}{15} *\frac{6}{15} = \frac{36}{225}* \frac{6}{15}\\ \frac{6}{15} *\frac{6}{15} *\frac{6}{15} =\frac{216}{3375}\\ \frac{6}{15} *\frac{6}{15} *\frac{6}{15} =0.064[/tex]
Thus '0.064' is our required answer
Laura is looking for a way to save money this year on her medical expenses. Insurance is starting to get expensive, and her budget is tight. She figures that she has a 75% chance of needing to visit the doctor and get medication once in the winter, for a total of about $400. She also figures there should be some room in the budget for emergencies, so she estimates a 5% chance she will need to spend $300 at an emergency room.
Is it reasonable for Laura to set her medical budget at $300 for the year?
Answer: A
Step-by-step explanation: The expected value is over $300, so Laura will likely need more money to cover her expenses.
its not that hard
It's not reasonable for Laura to set her medical budget at $300 for the year. Considering her predicted medical expenses, her expected annual cost is $315, making her budget slightly understated.
Explanation:The answer to whether Laura's medical budget of $300 for the year is reasonable or not involves a concept in probability known as expected costs. Let's consider both events: there is a 75% chance of spending $400 and a 5% chance of spending $300.
We calculate the expected cost for both scenarios:
The expected cost for the doctor visit and medication is 0.75 * $400 = $300The expected cost for emergency spending is 0.05 * $300 = $15
Adding these costs, we find that her expected annual medical costs are $315, not $300. Therefore, Laura might need to reconsider her budget, possibly increasing it slightly.

Connor is stuck in a traffic jam on a single-lane road. The traffic report tells him the traffic jam stretches for 5.5 miles. If Connor assumes each car is about 12.5 feet long, which calculation is most reasonable for Connor to use to find about how many cars are stuck in the traffic jam?
Connor can reasonably estimate that about 2323 cars are stuck in the traffic jam.
To find about how many cars are stuck in the traffic jam, Connor can divide the total length of the traffic jam by the length of each car.
Given:
- Length of traffic jam: 5.5 miles
- Length of each car: 12.5 feet
First, let's convert the length of the traffic jam from miles to feet since the length of each car is given in feet.
1 mile = 5280 feet
So, the length of the traffic jam in feet is:
[tex]\[ 5.5 \text{ miles} \times 5280 \text{ feet/mile} = 29040 \text{ feet} \][/tex]
Now, Connor can divide the total length of the traffic jam by the length of each car to find about how many cars are stuck:
[tex]\[ \frac{29040 \text{ feet}}{12.5 \text{ feet/car}} \approx 2323 \text{ cars} \][/tex]
