Answer:
1716
Step-by-step explanation:
I'm pretty sure
The manager can choose a group of 7 posters for a promotion in 1716 ways.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in a total of
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]
A movie theater has 13 new release movie posters
the manager choose a group of 7 for posters.
When we choose 7 posters, the order does not matter.
So we use a combination
We need to find 7 from 13 new release movie posters.
[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.\\\\^13C_7 = \dfrac{13!}{7! \times (13-7)!} ways.\\\\^13C_7 = \dfrac{13!}{7! \times6!} ways.\\\\^13C_7 = 1716[/tex]
The manager can choose a group of 7 posters for a promotion in 1716 ways.

Please help with 17 and 18
I’m not sure how to solve, what do I need to do??
Answer:
Step-by-step explanation:
It's helpful to draw it out, but you need a calculator for this.
You have the values of line b, line c, and angle C.
You can use sinC / c since you have C and c.
Solve for sinB by doing sinB/5.7 = sinC/8.6
you'll get the value of sinB, use inverse trig to solve for B (sin^-1)
Then you'll have the angle values for C and B. Add them, and subtract by 180 to find the angle measure of A.
Use the steps above to find a:
sinA (which u just found) / a = sinC (125) / c (8.6)

Kayla and Mario are playing with a football at the park on a windy day. Mark throws the football straight up in the air, and a gust of wind blows it 10 feet west and 4 feet south from Mark. If [x y] represents the original location of the football, write a matrix that represents the location of the translated ball.
Answer:
|x-10 y-4|
Step-by-step explanation:
Let the initial position where the football is thrown up the air be x and y.
After the ball is thrown up the air it moves 10 feet west 4 feet south because of the gust of wind.
Therefore the change in x is by 10 feet west and is at the point x - 10 and the change in y is by 4 feet south and is at the point y - 4.
Thus the matrix representing the position of the football is |x-10 y-4|.

QU | RT. Find TU.
Help plz...No links!! I will report!!
Answer:
34
Step-by-step explanation:
We solve the above question using Triangle Proportionality Theorem
This states that:
TU : TS = QR : RS
TU/TS = QR/RS
TU = ?
TS= 17
RS = 13
QR = 26
Hence,
TU/7 = 26/13
Cross Multiply
13 × TU = 17 × 26
TU = 17 × 26/13
TU = 17 × 2
TU = 34
Therefore, TU = 14

All triangles are closed figures.
All triangles are polygons.
All triangles have 3 right angles.
All triangles have 3 straight sides.
Multi answer BTW
Answer:
All Triangles are closed figure polygons that have three straight sides
Step-by-step explanation:
All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.

Given that events A and B are independent with P(A)=0.3P(A)=0.3 and P(A\cap B)=0.27P(A∩B)=0.27, determine the value of P(B)P(B), rounding to the nearest thousandth, if necessary.
Answer:
0.9
Step-by-step explanation:
Since A and B are independent hence;
P(A∩B) = P(A)P(B)
Given the following
P(A∩B) = 0.27
P(A) = 0.3
Required
P(B)
Substitute into the formula;
P(B) = P(A∩B)/P(A)
P(B) = 0.27/0.3
P(B) = 0.9
Hence the value of P(B) is 0.9
The value of P(B) is 0.9
What is probability?Probabilities are used to determine the chances of events
The given parameters are:
P(A) = 0.3
P(A ∩ B) =0.27
To find the value of P(B), we make use of the following formula
P(A ∩ B) = P(A) * P(B)
So, we have:
0.27 = 0.3 * P(B)
Divide both sides by 0.3
P(B) = 0.9
Hence, the value of P(B) is 0.9

If P (A) = 0.24, P(B) = 0.41, and P(A and B) = 0.18, what is P (A or B)?
A. 0.17
B. 0.47
C. 0.59
D. 0.65
The value of P(A or B) is 0.47. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, P (A) = 0.24, P(B) = 0.41, and P(A and B) = 0.18.
The formula to find P(A or B) is
P(A or B)=P(A)+P(B)-P(A and B)
P(A or B)=0.24+0.41-0.18
= 0.47
The value of P(A or B) is 0.47. Therefore, option B is the correct answer.

If a vector V is in standard position and the tip of the vector corresponds to the point (a, b), then we can write the vector in component form as
Answer:
[tex]V = <a,b>[/tex]
Step-by-step explanation:
Given
[tex]P= (a,b)[/tex] --- Point
Required
Component of V
From the question, we understand that V is in standard position.
This implies that V starts at the origin (0,0) and ends at (a,b)
So, vector V is:
[tex]V = <P(a,b) - O(0,0)>[/tex]
This gives:
[tex]V = <a-0,b-0>[/tex]
