Answer: 62
Explanation: It's an equilateral triangle
Answer:
False.
Event A and event B are not independent.
Step-by-step explanation:
We know that event A and event B are
A= {2,4} and B= {2,4,5}.
If the following condition satisfies then event A and event B are independent:
P( A and B)= P(A)*P(B).
Now A and B=?
A and B=A∩B= {2,4} ∩ {2,4,5}
A and B=A∩B={2,4}
The single fair die results in 6 outcomes so, the sample space will contain 6 elements.
Thus,
P(A∩B)=2/6=1/3
P(A)=2/6=1/3
P(B)=3/6=1/2
P(A)*P(B)=1/3*1/2=1/6
As,
P(A∩B)≠P(A)*P(B)
1/3≠1/6
Thus, events A and event B are dependent.
Answer:
A. 5 + 2.75 · S ≤ 21
Step-by-step explanation:
So we know that it has to be less than or equal to $21 because that's all she has to spend. So we can automatically rule out the equations with ≥ because that means greater than.
We can also rule out the equations that have 50 at the very end because that's just how far she wants to travel.
Answer:
All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.
Step-by-step explanation:
The old math saying: "Every square is a rectangle, but not all rectangles are squares."
What makes a rectangle a rectangle is that it has four right angles.
A square also has four right angles. Therefore, a square is a type of rectangle.
<h3>What makes the other answers wrong:</h3>
A rectangle does not have equal lengths on all four sides like a square does.
A square MUST have four right angles for it to be a square.

Answer:
648 seconds
Step-by-step explanation:
First we need to see how much 60% of 756 is, so we multiply 756 × 0.60 and we get 453.6, so we now just need to see in how many seconds (0.7) we will get 453.6 oz, so we simply divide 453.6 ÷ 0.7 = 648. This is your answer. We can check this by multiplying 648 × 0.7 and getting 453.6
