Answer:
1) if tₙ = 3*n - 2, we want to find the value of S(5), which is the sum of the first 5 terms.
We can simply compute the sum directly, it is:
S(5) = t₁ + t₂ + t₃ + t₄ + t₅
S(5) = (3*1 - 2) + (3*2 - 2) + (3*3 - 2) + (3*4 - 2) + (3*5 - 2)
S(5) = 35
Then the correct option here is a).
2) This is not correctly written.
I will assume that we the n-th term is:
tₙ = n^2 + 3*n
And we want S(5) again
Then:
S(5) = t₁ + t₂ + t₃ + t₄ + t₅
S(5) = (1^2 + 3*1) + (2^2 + 3*2) + (3^2 + 3*3) + (4^2 + 3*4) + (5^2 + 3*5)
S(5) = 100
So the correct option is (d)
(Notice that if we had chosen any other S(n), the answer is still option (d) )

4. Tori bought x shares of Mattel stock for m dollars per share. She sold
all of the shares months later for y dollars per share. Express her cap-
ital gain or loss algebraically.
Answer:
mx = y
or
y = mx
Step-by-step explanation:
If she pays m per share, and x represents each share, you will multiply m and x. If she sold all them for the value of y. Then you set mx equal to y.
mx = y
or
y = mx

Find the number of students who have access to both a computer and mobile phone?
simplify (0.01)^(-0.5)
Answer:10
Step-by-step explanation:
In fraction,
(1/100)^(-1/2)
Equivalent to 1/((1/100)^(1/2))
Power 1/2 is basically square root
So we have 1/(1/10) after applying square root to 1/100
so final step
1 divide (1/10) = 10

work out m and c for the line y= 2x+1
Answer:
m = 2, c = 1
Explanation: In the y = mx + b (or y = mx + c) format, the m is the slope of the line and the c/b is the y-intercept, or where the line crosses the y-axis. If we substitute the information from the given equation, y = 2x + 1, into the general formula, we know that the m is 2 and c is 1.

What is 6/11 in decimal form, to the nearest thousandth
Answer:
0.006
Step-by-step explanation:
Answer:
Explanation:
611 or 6÷11=0.545454545....
The hundredth position is two positions to the right of the decimal point. For this problem it is the 4:
0.545454545....
To round to the nearest hundredth you must look at the digit in the position immediately to the right of the digit in the hundredth place, which is the 5 in the thousandth place:
0.545454545....
If the digit to the right is greater than or equal to 5 you add 1 to the digit you are rounding to and make everything to the right 0.
If the digit to the right is less than 5 you add keep the digit you are rounding to the same and make everything to the right 0.
In this problem the digit to the right is a 5 so we add 1 to the digit we are rounding to and make everything to the right 0.
0.545454545....=0.550000000....=0.55

You invest $2,000 in an investment that pays an annual interest rate of 7.5% with monthly compounding. How many months will it take for your investment to be worth $3,500
Answer:
10 years
step-by-step explanation:
First, divide 7.5 by 100, you should get 0.075, then multiply 0.075 by 2000, you should get 150, thats how much interest he gains each year, now subtract 2000 from 3500 to see how much he needs to get to 3500, you should get 1500, now divide 1500 by 150, you should get 10, which is how many years he will need to get to 3500 from 2000
- Max can read about 150 words per minute. Unfortunately for Max, he has waited until
this weekend to do all his reading. The book he has to read is 310 pages long. If a typical
paperback has about 350 words per page, how many hours should he set aside for this
reading?
A. 12 days
B. 12 hours
C. 72.3 days
D. 610 hours
Answer:
B) 12 hours
Explanation
Max can read 150 words per minute. 350 words per page divided by 150 is 2.333, so max can read 1 page in around 2 minutes. There are 310 pages. 2.333 * 310 is around 723. 723 minutes converted to hours is 12 hours. Boom. Done.

A carnival game has 150 rubber ducks floating in a pool. The person playing
the game takes out one duck and looks at it.
• If there's a red mark on the bottom of the duck, the person wins a small
prize.
Many ducks do not have a mark.
After 50 people have played the game, only 3 of them have won a small
prize.
Estimate the number of the 150 ducks that you think have red marks on
the bottom.
Answer:
Pretty sure it's 17 ducks.
The correct answer is based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.
To estimate the number of ducks with red marks on the bottom, we can use the information given: out of 50 people playing the game, only 3 have won a small prize.
We can assume that the probability of winning a small prize is the same for each player, and that each duck is equally likely to have a red mark.
If only 3 out of 50 people have won a small prize, we can estimate that the probability of winning is approximately 3/50.
Let's denote the number of ducks with red marks as "x." The probability of winning a small prize can be represented as x/150 (since there are 150 ducks in total).
Setting up the equation:
x/150 = 3/50
To solve for x, we can cross-multiply:
50x = 3 * 150
50x = 450
Dividing both sides by 50:
x = 9
Therefore, based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.
