Answer: 40/81
===========================================
Work Shown:
B = selecting 1 blue
R = selecting 1 red
P(B) = 5/9, since there are 5 blue out of 5+4 = 9 total
P(R) = 4/9, since there are 4 red out of 9 total
P(2 blue) = P(B)*P(B) = (5/9)*(5/9) = 25/81
P(2 red) = P(R)*P(R) = (4/9)*(4/9) = 16/81
The last two equations are valid because we are sampling with replacement. Each selection is independent.
-------------------
P(2 same color) = P(2 blue OR 2 red)
P(2 same color) = P(2 blue) + P(2 red)
P(2 same color) = 25/81 + 16/81
P(2 same color) = (25+16)/81
P(2 same color) = 41/81
-------------------
P(2 different color) = 1 - P(2 same color)
P(2 different color) = 1 - 41/81
P(2 different color) = 81/81 - 41/81
P(2 different color) = (81-41)/81
P(2 different color) = 40/81
(A) 8.85
(B)10.00
i think is the answer
hope i helped :)
<span>Complete the slope-intercept form equation of the line with slope − 8 that passes through the point (0,−2) (don't mention (0,-2) more than once)
y = mx + b, with m= -8, comes out to y = -8x + b.
Subst. 0 for x and -2 for y and then calculate b: -2 = 0 + b => b = -2
Then the equation is y = -8x - 2.</span>
Answer:
C
Step-by-step explanation:
Average rate = page/hour
2 hours and 40 minutes into hours is 2.67 hours.
Average rate = 96/2.67
Average rate = 36
Idk this answer because no triangles are shaded.
