Find the series in A.P whose sum to n terms is n*(n+2)
Answer:
3, 5, 7, 9, 11, .........
Step-by-step explanation:
Given
[tex]S_{n}[/tex] = n(n + 2) , then
S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3
S₂ = 2(2 + 2) = 2(4) = 8
S₃ = 3(3 + 2) = 3(5) = 15
Thus
a₂ = S₂ - S₁ = 8 - 3 = 5
a₃ = S₃ - S₂ = 15 - 8 = 7
The first 3 terms are 3, 5, 7
This is an AP with common difference d = 2, then
a₄ = a₃ + 2 = 7 + 2 = 9
a₅ = a₄ + 2 = 9 + 2 = 11
and so on
If two 12-sided dice are rolled, what is the probability that both numbers will be even?
ANSWERS:
1/2
73/144
1/4
71/144
The probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
Given that two 12-sided dice are rolled and need to calculate the probability of getting an even number.
Number of favorable outcomes = 6 x 6 = 36
Number of sample = 12 x 12 = 144
The probability of getting an even number will be calculated as:-
Probability = Number of favorable outcomes / Number of sample
Probability = 36 / 144
Probability = 1 / 4
Therefore, the probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.

The probability of selecting a receipt of more than $20 is 1/3 or 0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The amount on the receipt = {8, 10, 10, 15, 25, 32}
Total outcome = 6
The amounts are grouped as more than $20 and less than $20.
The event is the amount on receipt more than $20 = {25, 32}
Total favourable outcome = 2
Probability = 2/6 = 1/3 or
= 0.33
Thus, the probability of selecting a receipt of more than $20 is 1/3 or 0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.

Chocolate chip and peanut butter cookies are randomly chosen from a cookie jar and placed onto a plate. The first plate had four chocolate chip cookies and one peanut butter cookie. A second plate was prepared with 2 chocolate chip cookies and P peanut butter cookies. If the total probability of drawing a chocolate chip cookie from the first plate and then the second plate is 8/25, how many peanut butter cookies, P, are on the second plate? PLEASE HELP THIS IS A FORMATIVE I HAVE TO FINISH THIS TEST AT 12:55, AND IT IS 12:29 RIGHT NOW PLEASE HELP <:(
Answer:
3 peanut cookies
Step-by-step explanation:
Given that :
Plate 1:
Number of chocolate chip = 4
Number of peanut butter cookies = 1
Probability of drawing chocolate chip cookies from plate 1 :
Probability =( number of required outcome / Total possible outcomes)
P(chocolate chip) = 4 / 5
Plate 2:
Number of chocolate chip = 2
Number of peanut butter cookies = p
P(chocolate chip) = 2 / (2 + p)
Probability of drawing chocolate chip from plate 1 and then plate 2 = 8/ 25
(4/5) * 2/(2+p) = 8/ 25
8 / (10 + 5p) = 8/ 25
8(10 + 5p) = 8 * 25
80 + 40p = 200
40p = 200 - 80
40p = 120
p = 3

At a high school football game, admission is $5 for students and $10 for non-students. There were 500 people at the first game, and the school made $4,000 from admissions. In this activity, you will find the number of students and non-students at the game.
Please write the two equations algebraically and then solve :)
Answer:x = 200 students
y = 300 non-students
Step-by-step explanation:
5x + 10y = 4000
x + y = 500
Set y = 500-x
5x + 10(500-x) = 4000
5x + 5000-10x
-5x + 5000 = 4000
-5x = -1000
x = 200 students
y = 300 non-students
Let's double checks
5(200) + 10(300)
1000 + 3000 = 4000

What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Ms. Kraus is 1.75 m tall. When her shadow is 1 m.
Let the shadow of a 265 m tall building be 'x' m.
Therefore by the ratio proportion method.
1.75 : 1 : : 265 : x.
1.75/1 = 265/x.
1.75x = 265.
x = 265/1.75.
x = 151.42 Or 151 m.

Find the values of x and y
Answer:
x = 8
y = 21
Step-by-step explanation:
The angle (7x + 12)° and the angle (12x-28)° are alternate interior angles and so has got the same measurement
7x + 12 = 12x - 28
12 + 28 = 12x - 7x
40 = 5x divide both sides by 5
8 = x
The sum of angle (12x - 28)° and (9y - 77)° must be equal because they make a straight line with the measure of 180°
12x - 28 + 9y - 77 = 180 we already found the value of x as 8 so let's rewrite the equation
12 × 8 - 28 + 9y - 77 = 180
96 - 28 - 77 = 180 add like terms
9y - 9 = 180
9y = 189 divide both sides by 9
y = 21
