Answer:
Step-by-step explanation:
66 mile per hour .
Answer:
53.57%
Step-by-step explanation:
We have to calculate first the specific number of events that interest us, if at least 3 are girls, they mean that 2 are boys, therefore we must find the combinations of 3 girls of 5 and 2 boys of 3, and multiply that, so :
# of ways to succeed = 5C3 * 3C2 = 5! / (3! * (5-3)!) * 3! / (2! * (3-2)!)
= 10 * 3 = 30
That is, there are 30 favorable cases, now we must calculate the total number of options, which would be the combination of 5 people from the group of 8.
# of random groups of 5 = 8C5 = 8! / (5! * (8-5)!) = 56
That is to say, in total there are 56 ways, the probability would be the quotient of these two numbers like this:
P (3 girls and 2 boys) = 30/56 = 0.5357
Which means that the probability is 53.57%
Answer:
No. The den will have 8 times the volume of the bedroom.
Step-by-step explanation:
The volume of the bedroom:
9 * 5 * 7 = 315 cubic feet
The volume of the den:
(9*2) (5*2) (7*2)
18 * 10 * 14 = 2,520
2,520/315 = 8
To divide fractions you flip the second fractions and multiply.
9/18 divided by 3/6 becomes -> 9/18 x 6/3
<u>9 </u>x <u>6 </u>-> <u>54</u>
18 x 3-> 54
your answer would simplify to 1.
Answer:
its answer is a . 28 th term
Step-by-step explanation:
Given
an = 2 + 7(n- 1)
Now
a28 = 2 + 7( 28 -1)
= 2 + 7 * 27
= 2 + 189
= 191
Hope it helps:)
