Answer:
0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Dinosaur
Event B: Plush.
The probability that a toy Raymond picks out of a box is a dinosaur is 75%.
This means that
The probability that a toy Raymond picks out of a box is both plush and a dinosaur is 30%.
This means that
What is the probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur?
0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.
Answer:
Option C, The triangle is an isosceles triangle.
Step-by-step explanation:
On a coordinate plane, triangle A B C is shown. Point A is at (negative 1, 3), point B is at (negative 5, negative 1), and point C is at (3, negative 1).
Use distance formula to find
We find only two sides are equal and third side is not equal
Hence this is an isosceles triangle
Answer:
8 and 9
Step-by-step explanation:
If x is the smaller integer, and x + 1 is the larger integer, then:
(x + 1)² + 3x = 105
x² + 2x + 1 + 3x = 105
x² + 5x − 104 = 0
(x + 13) (x − 8) = 0
x = -13 or 8
Since x is positive, x = 8. So the two integers are 8 and 9.
3/100 is the answer i hope this helps
Answer:
2x - 2y
Step-by-step explanation:
P = 7x + 2y
P =a + b + c
7x + 2y = 2x + y +3x - 5y + c
7x + 2y - 5x - 4y
= 2x - 2y
