Answer:1,0.5, or 0 it depends
Explanation:
The probability that one event occurred depends on the total of random event, being 1 the most of the probabilities
If the two marbles are blue the probability to select a marble blue is 1
If one of the marbles is blue and the other marble is of any color the probability to select the blue marbles is:
P=1 - 1/2=1/2
Being 1/2 or 0.5 the answer
If any of the marbles are blue then the probabilities are 0
Answer:
The radius of the pie is 6.17 in.
Step-by-step explanation:
The formula for arc length as a function of radius is
s = r·Ф, where Ф is the central angle in radians.
Here we know that the arc length is 7.85 in. Assuming that the whole pie has been cut into 8 equal pieces, the central angle of one such piece is
2π / 8, or π /4 (radians).
thus, s = r·Ф, solved for r, is r = s/Ф
and in this instance r = (7.85 in)/(π/4). Evaluating this, we get:
r = 6.17 in
The radius of the pie is 6.17 in.
Answer:
y ≈ 5.2
Step-by-step explanation:
∠ F = 180° - (42 + 48)° ← sum of angles in a triangle
∠ F = 180° - 90° = 90°
Thus Δ DEF is right at F
Using the sine ratio in the right triangle
sin48° = 
= 
= 
( multiply both sides by 7 )
7 × sin48° = y , then
y ≈ 5.2 ( to the nearest tenth )
