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

Step-by-step explanation:
The sum of the angles of a triangle is 180
Let the unknown angle be x
94+45+x = 180
Combine like terms
139 +x = 180
Subtract 139 from each side
139+x-139= 180-139
x =41
May 18, 11:05:10 PM When Jace runs the 400 meter dash, his finishing times are normally distributed with a mean of 81 seconds and a standard deviation of 1.5 seconds. Using the empirical rule, what percentage of races will his finishing time be between 79.5 and 82.5 seconds?
Answer:
68% of races will his finishing time be between 79.5 and 82.5 seconds
Step-by-step explanation:
Mean time = 81 seconds
Standard deviation = 1.5 seconds
According to the empirical rule : 68%, 95%, 99% lies within 1, 2, and 3 standard deviations of the mean respectively.
Hence, for a finishing time between : 79.5 and 82.5
79.5 = 81 - 1.5 (1 standard deviation to the left of the mean)
82.5 = 81 + 1.5 (1 standard deviation to the right of the mean)
Hence,
79.5 and 82.5 lies within 1 standard deviation from the mean and it is Hence has a percentage of 68%
Solve y=f(x) for x. Then find the input when the output is – 3.
f(x) = 1/2x-3
x=
The input is
when the output is -3.
Given:
[tex]y=f(x)[/tex]
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
To find:
The input when the output is – 3.
Solution:
We have,
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
Substituting [tex]f(x)=y[/tex], we get
[tex]y=\dfrac{1}{2}x-3[/tex] ...(i)
We need to find the input when the output is – 3. It means, we have to find the value of x when [tex]y=-3[/tex].
Putting [tex]y=-3[/tex] in (i), we get
[tex]-3=\dfrac{1}{2}x-3[/tex]
[tex]-3+3=\dfrac{1}{2}x[/tex]
[tex]0=\dfrac{1}{2}x[/tex]
Multiply both sides by 2.
[tex]0=x[/tex]
Therefore, the input is 0 when the output is -3.

im lost again is getting harder for me ahhh im only in 7th grade
Answer: 72
Step-by-step explanation:
The formula for the area of a triangle is l * w / 2. In this case, the area of one triangle is 12, because 3*8=24/2=12. There are two triangles, so the combined area = 24. The area of the square is 48 because 6 * 8 = 48. Add it up, it makes 72.

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 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.

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.

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
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...)
Evaulate 9÷3[(20-7) -2to the power of 2]
Answer:
27
Step-by-step explanation:
Evaulate 9÷3[(20-7) -2to the power of 2]
9÷3[(20-7) - 2²]
9 ÷ 3 = 3
[(20-7) - 2²] = (13 - 4) = 9
Hence ;
9÷3[(20-7) - 2²]
3(9)
= 27
