Answer:
SA = π3^2 + π3(7.5)
Step-by-step explanation: r is radius and L
is r*l/2
so 3*5/2=15/2=7.5
seriously look at a problem more carefully and memorise your formulas!
Answer:
102
Step-by-step explanation:
34*3=102
the dot in the middle is just another way to say that it is multiplying the equation so it just mean that your are multiplying 34 by 3 which is 102
Answer:
The total number of apples is 17
Step-by-step explanation:
(a)
Number of green apples = 4
P ( that all three apples are green)
= (limit 4 and 3) / (limit 17 and 3)
= 4! / 3!(4−3)!
= 17! / 3!(17−3)!
= 1 / 170
= 0.005
(b)
Number of red apples = 8
P(that all three apple are green)
=(limit 8 and 3) / (limit 17 and 3)
= 8! / 3!(8−3)!
= 17! / 3!(17−3)!
= 7 / 85
= 0.082
Now,
P(that no three apple is red)= 1−0.082 = 0.918
c)
P(of selecting 4 apple that contain at least 2 red apples)
= (limit 8 and 2) /( limit 17 and 2) X (2/15) + (limit 8 and 3) /(limit 17 / 3) X (1/14)
= (7/34) × (2/15) + (7/85) × (1/14)
= 0.027 + 0.058
= 0.085
d)
P(that the second apple selected is yellow given that the first apple is red)
= (limit 5 and 1) / ( limit 16 and 1)
= 5! / 1!(5−1)!
= 16! / 1!(16−1)!
= 5 /16
= 0.3125
Answer:
-348.33
Step-by-step explanation:
Use PEMDAS as your guide.
(-342-8) - (-5/2+1)
PEMDAS
parenthesis
-350 - (-5/3)
PEMDAS
Dvisision
-350- (-1.67)
= - 348.33
Hope this is what your looking for!
