The sequence 2,5,8,..... The sum of the 1st 36 terms in arithmetic sequence is 1962.
Given that,
The sequence 2,5,8,.....
We have to find the sum of the 1st 36 terms of the sequence.
We have an sum of the sequence formula from arithmetic sequence.
The sum of all the digits in an arithmetic sequence is determined using the sum of the arithmetic sequence formula. Remember that the addition of the members is the definition of a finite arithmetic sequence. The typical order of the arithmetic sequence is (a, a + d, a + 2d,...), with "a" standing for the first term and "d" for the common difference.
Sum of the arithmetic sequence is S = n/2 {2a + (n − 1) d}
Where
S is the total of the mathematical sequence,
a is the first term,
d is difference of the terms,
n is number of terms in the sequence.
So, now a =2, n=36,d=5-2=3
S=36/2{ 2×2+(36-1)×3}
S=18{4+(35)×3}
S=18(4+105)
S=18×109
S=1962
Therefore, the sum of the 1st 36 terms in arithmetic sequence is 1962.

A game is played using ne die. If the die is rolled and shows 3, the player wins $45. If the die shows any number other than 3, the player wins nothing. If there is a charge of $9 to play the game, what is the game's expected value?
Answer:
-$13.5
Step-by-step explanation:
Let x be a random variable of a count of player gain.
- We are told that if the die shows 3, the player wins $45.
- there is a charge of $9 to play the game
If he wins, he gains; 45 - 9 = $36
If he looses, he has a net gain which is a loss = -$9
Thus, the x-values are; (36, -9)
Probability of getting a 3 which is a win is P(X) = 1/6 since there are 6 numbers on the dice and probability of getting any other number is P(X) = 5/6
Thus;
E(X) = Σ(x•P(X)) = (1/6)(36) + (5/6)(-9)
E(X) = (1/6)(36 - (5 × 9))
E(X) = (1/6)(36 - 45)
E(X) = -9/6 = -3/2
E(X) = -3/2
This represents -3/2 of $9 = -(3/2) × 9 = - 27/2 = -$13.5
Each marble bag sold by Mary's Marble Company contains 5 blue marbles for every 4 purple
marbles. If a bag has 35 blue marbles, how many purple marbles does it contain?
Answer:
The total no. of purple marbles will be:
[tex] \boxed{ \underline{ \rm{28}}}[/tex]
Step-by-step explanation:
It is given that for every 5 blue marbles, we have 4 purple marbles. And similarly we have to find for the no. of purple marbles for 35 blue marbles.
First, Let's divide these 35 blue marbles in groups of 5. We will get:
➝ 35 ÷ 5 = 7 groups
For each group of 5 marbles, there are 4 purple marbles. So for 7 groups, No. of purple marbles will be:
➝ 4 × 7 = 28 purple marbles.
And we are done! :D

Answer:
Correct answer is option C. 354.9 mLThe volume of soap that Ryan measured is 354.9 mL. Therefore, option C is the correct answer.
Given that, for the volume of soap in a bottle, Ryan determined the margin of error as 354.85 mL to 354.95 mL.
We need to find the volume of soap that he measured.
What is the margin of error?A margin of error tells you how many percentages points your results will differ from the real population value.
Now, the margin of error is 354.85 - 354.95
The volume=354.9 mL (Mid value of 354.85 - 354.95 )
The volume of soap that Ryan measured is 354.9 mL. Therefore, option C is the correct answer.

In a three-digit number, the tens digit is the same as the hundreds digit. The ones digit of this number is equal to 1/3 of the sum of the other two digits. Find the number if the sum of all its digit is equal to 24.
Answer:
996
Step-by-step explanation:
the three digit number is;
996
Step-by-step explanation:
The three digit can be written xyz
ones digit is equal to 1/3 the sum of the two other digits
z = 1/3(x + y)
x + y + z = 24
Tens digit is same as hundreds digit
That means x = y
z = 1/3 (x + x) = 2x/3
So;
2x/3 + x + x = 24
Multiply through by 3
2x + 3(2x) = 72
8x = 72
x = 72/8
x = 9
x = y = 9
z = 1/3(18)
z = 6

A school had 225 students enrolled last year. This year, 260 students are enrolled. Find the percent of change to the
nearest percent.
Answer:
15.5%
Step-by-step explanation:
No of students that had enrolled last year = 225
This year, 260 students are enrolled.
We need to find the percent of change in the number of students. It can be calculated as :
P = (change in no of students/initial no of students)×100
[tex]\%=\dfrac{260-225}{225}\times 100\\\\=15.5\%[/tex]
So, the percent change is 15.5%.
Describe what a loan discount point is and what effect it has on a home loan.

M is the midpoint of line segment LN. Find the length of LN
Answer:
Step-by-step explanation:
Here is the complete question;
M is the midpoint of line segment LN. If LM= 3x + 5 and LN= 5x + 40, find the length of LN.
Since M is the midpoint of LN, hence LM + MN = LN and LM = MN
LM + LM = LN
2LM = LN ..... *
Given;
LM= 3x + 5
LN= 5x + 40
Substitute into the eqn *
2(3x+5) = 5x+40
6x+10 = 5x+40
6x-5x = 40-10
x = 30
Get the length LN
LN= 5x + 40
LN = 5(30)+40
LN = 150+40
LN = 190
