W= l - 5 where w = width and l = length
area = 84 = l*w = l(l-5)
l(l-5) = 84
l^2 - 5l - 84 = 0
(l - 12)(l + 7) = 0
l = 12
length = 12 and width = 7
It is substitution. Because you are substituting 3=y into x+5=3
Answer:
a) volume = 321.55 in³
Step-by-step explanation:
volume = 4/3πr³ = 4/3(3.14)4.25³) = 321.55 in³
Answer:
1/3
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur
Probability = Expected/Total outcome
Since the experiment requires rolling a dice
S = {1, 2, 3, 4, 5, 6}
Total outcome n(S) = 6
Number greater than 4 are;
Events E = {5,6}
Expected outcome n(E) = 2
Probability of rolling a number greater then 4 = 2/6
Probability of rolling a number greater then 4 = 1/3
