Answer: 3/8
Step-by-step explanation:
When three coins are flipped, we get 8 total outcomes: (HHH,HHT,HTH,HTT,THH,THT,TTH,TTT)
Two tails and one head is (HTT, TTH, THT)
Probability = number of favorable outcomes/ number of total outcomes
Number of Favorable outcomes = 3
Number of Total outcomes= 8
Therefore, probability of getting 2 tails and one head
= 3/8
It called a (tangent)
Thank you have good day ;)
If this is a true or false questions. It's true
Answer:
B = 4
Step-by-step explanation:
Given that B is directly proportional to A then the equation relating them is
B = kA ← k is the constant of proportionality
To find k use the condition B = 3 when A = 18 , then
3 = 18k ( divide both sides by 18 )
k =
= 
B =
A ← equation of proportion
When A = 24, then
B =
× 24 = 4
Answer:
972π in³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ← r is the radius
Here r = 9, thus
V =
π × 9³ =
π × 729 ( divide 3 and 729 by 3 )
= 4π × 243
= 972π in³
