Answer:
a. 32 ft²
Step-by-step explanation:
Given:
L = 3 ft
W = 2 ft
H = 2 ft
Required:
Surface Area of the box
SOLUTION:
Surface area = 2LW + 2LH + 2HW
Plug in the values
Surface area = 2(3*2) + 2(3*2) + 2(2*2)
SA = 12 + 12 + 8
SA = 32 ft²
Plug in x = 7. Then use the order of operations (PEMDAS) to simplify
y = 11 - 5*x
y = 11 - 5*7 .... x has been replaced with 7 (since x = 7 is given)
y = 11 - 35
y = -24
Suppose there are x number of clubs in the pack
P( draw a diamond) = 13 / 59
P( draw a club) = x / 58
so P( diamond then a club) = 13x / (58*59) = 13x / 3422
so we have the equattion
117 / 1711 = 13x / 3422
234 / 3422 = 13x / 3422
therefore x = 234 / 13 = 18 clubs :-
that is 5 more clubs than in a normal pack
So the number of extra spades = 59 - 52 - 5 = 2
Answer:
Probability the first is a communications major and the second is a business major = 0.03
Step-by-step explanation:
let the total number of students be 100
Event A= Business Majors = 15%
Event B = Communication Majors = 20%
P(A) = ⇒ P(A) = 0.15
P(B) = ⇒ P(B) = 0.2
P( A and B) = P(A) × P(B)
= 0.15 × 0.2
= 0.03
