Answer:
10.5
Step-by-step explanation:
To find mean, you add all the terms and divide your sum by the number of terms there are. Since the terms are 5 and 16, you would do 5+16=21. Then, since there are two terms, divide 21 by 2 and your mean is 10.5.
The geometric mean of 5 and 16 is √80 ≈ 8.94.
What is Geometric mean?Geometric mean of two or more numbers is defined as the square root of the product of all the numbers.
Simply, if the two numbers are a and b,
Geometric mean of those numbers = √(ab)
Here the given numbers are 5 and 16.
Geometric mean of 5 and 16 = √(5 × 16) = √80 ≈ 8.94
Hence the geometric mean is approximately 8.94.

Rewrite the given parametric equations in Cartesian from x(t) = 2t– 1 y(t) = 5t
Hi there!
[tex]\large\boxed{(-\frac{5}{3},-\frac{5}{3})}[/tex]
We can begin by setting the two expressions equal to solve for t:
2t - 1 = 5t
Subtract 2t from both sides:
-1 = 3t
Divide both sides by 3:
t = -1/3
Plug in this value of t into x(t) and y(t):
x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3
y(-1/3) = 5(-1/3) = -5/3
Thus:
(-5/3, -5/3) are the corresponding coordinates.

Answer:
f = 119
e = 61
d = 90
Step-by-step explanation:
Answer:
Angle e is 61
Angle f is 119
Angle d is 90
Step-by-step explanation:
When two lines meet, the opposite angles are the same, so e is 61. On a straight line, there are 180 degrees, so angle f would be 180-61=119. Angle d uses the same method, the square in the bottom right tells you one side is 90, so for the other side you take 180-90, and you get 90.

The bowling team at Lincoln High School must choose a president, vice president,
and secretary. If the team has 12 members, how many ways could the officers be
chosen?
Answer:
The officers can be chosen in 1320 ways.
Step-by-step explanation:
The order in which the officers are chosen is important(the first is president, second vice president and third secretary) which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
3 officers from a set of 12. So
[tex]P_{(12,9)} = \frac{12!}{9!} = 1320[/tex]
The officers can be chosen in 1320 ways.
A circle is centered at (5,-9) and has a radius of 12. Which of the following is the equation for this circle?
a: (x-5)^2+(y+9)^2=12
b: (x-5)^2+(y+9)^2=144
c: (x+5)^2+(y-9)^2=144
d: (x+5)^2+(y-9)^2=12
Will vote Brainliest!! NEED ANSWERS ASAP!!
Answer:
b.
Step-by-step explanation:
The general form for a circle is:
(x - a)^2 + (y - b)^2 = r^2
where (a, b) is the centre and r = the radius.
So here (a, b) = (5, -9) and r = 12 giving:
(x - 5)^2 + (y - (-9))^2 = 12^2
(x - 5)^2 + (y + 9)^2 = 144.
Answer:
(x - 5)^2 + (y + 9)^2 = 144. is correct

If A is a 2x2 matrix and B is a 2x1 matrix, what is the dimension of AB?
Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix

A summer camp has 492 campers who will be going on an outing. Estimate the number of vans needed to accommodate the entire camp if each van can comfortably
hold 12 passengers. Then calculate the actual number of vans that will be needed.
Answer: 41 vans will be needed.
Step-by-step explanation:
There are a total of 492 campers. We know that each van can hold a total of 12 passengers.
So, simply divide 492 by 12 to get the total amount of vans needed.
492/12 = 41 vans.

The PTO is selling raffle tickets to raise money for classroom supplies. A raffle ticket costs $3. There
is 1 winning ticket out of the 300 tickets sold. The winner gets a prize worth $62. Round your answers
to the nearest cent.
What is the expected value (to you) of one raffle ticket? $
Calculate the expected value (to you) if you purchase 6 raffle tickets. $
What is the expected value (to the PTO) of one raffle ticket? $
If the PTO sells all 300 raffle tickets, how much money can they expect to raise for the classroom
supplies? $
Answer:
Suppose that in a given event, there are N outcomes:
{x₁, x₂, ..., xₙ}
Such that the probabilities are:
{p₁, p₂, ..., pₙ}
The expected value is:
EV = x₁*p₁ + x₂*p₂ + ... + xₙ*pₙ
In this case, we know that each ticket costs $3.
There is 1 winning ticket out of 300 tickets, where the prize is $62.
Then we have two events, the one where you win.
x₁ = $62 - $3 = $59
With a probability:
p₁ = 1/300
The one where you don't win (and still pay for the ticket):
x₂ = -$3
p₂ = 299/300
a) Then the expected value is:
EV = ( 1/300)*$59 + (299/300)*(-$3) = -$2.79
b) The expected value is additive, this means that if you buy 6 tickets, the expected value will be equal to 6 times the expected value of a single ticket.
EV = 6*(-$2.79) = -$16.74
c) For the PTO the events are:
Winner ticket, so you lose $62 and win $3 for selling the ticket.
x₁ = $3 - $62 = -$59
p₁ = 1/300
Normal ticket, you win $3.
x₂ = $3
p₂ = 299/300
In this case the expected value is:
EV = (1/300)*(-$59) + (299/300)*$3 = $2.79
d) If the PTO sells the 300 tickets, then the expected value is 300 times the expected value for a single ticket:
EV = 300*$2.79 = $837
We should have the exact same than selling the 300 tickets:
300*$3 = $900
minus the $62 for the price:
$900 - $62 = $838
There is a difference of $1, that happens because we rounded the value of the expected value (the actual one was $2.792...)
In the diagram belowthe length of segment AB is 10, the length of segment AD is 25, and the length of segment AEis 20. What is the length of segment AC? A. 6 B. 10 C. 5 D. 8
The image of the triangle is missing, so i have attached it.
Answer:
Option D: 8
Step-by-step explanation:
We are given;
AB = 10
AD = 25
AE = 20
We want to find length of AC.
By proportion, we can find length of AC. Thus;
AB/AD = AC/AE
Plugging in the relevant values, we have;
10/25 = AC/20
AC = (10 × 20)/25
AC = 8
