Answer:
Step-by-step explanation:
You need answer choices for someone to answer.
Given that an experiment results in one of the sample points E1, E2, E3, E4,
or E5.
Then P(e1) + P(e2) + P(e3) + P(e4) + P(e5) = 1
If P(E1)=0.1, P(E2)=0.1, P(e4)=0.2, and
P(E5)=0.3., then P(E1) = 1 - 0.1 - 0.1 - 0.2 - 0.3 = 0.3
Therefore, P(e3) = 0.3
Answer:
f(-1) = 3
Step-by-step explanation:
f(-1) means the value of y at x = -1.
So what's the value of y at x = 1?
First, focus on the graph and look at x = -1.
Next, see which y-value does graph pass through when x = -1.
Looks like the graph passes y = 3 when x = -1
Thus, f(-1) = 3
Answer:
Coordinates of point A are
(-3,-2)
Origin lies in the center of coordinate system. That means that you can picture this as right triangle with sides 3 and 2 and you need to find hypotenuse of it.
Using pythagoras theorem we calculate:
h^2 = 3^2 + 2^2 = 13
h = sqrt 13
Answer is b

3 + 12 = 15 So, for every 15 beads, 3 are red. 15 * 3 = 45 So, 9 beads out of 45 are red.
