Answer:
See below in bold,.
Step-by-step explanation:
There are 30-17 = 13 boys in the class.
a. Prob(First is a boy ) = 13/30 and Prob( second is a boy = 12/29).
As these 2 events are independent:
Prob( 2 boys being picked) = 13/30 * 12/29 = 26/145 or 0.179 to the nearest thousandth.
b. By a similar method to a:
Prob ( 2 girls being picked) = 17/30 * 16/29 = 136/435 = 0.313 to the nearest thousandth.
c. Prob (First student is a boy and second is a girl) = 13/30 * 17/29 = 221/870.
Prob ( first student is a girl and second is a boy) = 17/30 * 13/29 = 221/870
These 2 events are not independent so they are added:
Prob( one of the students is a boy) = 2 (221/870 = 221/435 = 0.508 to the nearest thousandth.
Answer:
60cm3
Step-by-step explanation:
Your base has 4
width has 5
5 x 4 = 20
Your height has 3
20 x 3 = 60
A) height of a cylinder: 7.96
b) height of come: 1.43
c) radius of cylinder: 4.07
d) radius of cone: 2.82
e) radius of sphere: 9
use the following formulas to solve:
a) volume= (pi)(radius^2)(height) and substitute what’s given
b) (1/3)(pi)(radius^2)(height) and substitute the given
c) volume= (pi)(radius^2)(height) and substitute what’s given
d) (1/3)(pi)(radius^2)(height) and substitute the given
e) volume= (4/3)(pi)(radius^2) and substitute the given
The product of constant factors 12 and x plus 3.
Answer: $0.65
Explanation: First find how much Jose paid for each bag
$375 / 750
So $0.50 per bag
Now add $0.15 to that
$0.50 + $0.15
That added together is
$0.65
