Answer:
1/24
Step-by-step explanation:
The probability of the dice landing with a 5 up is 1/6; that of drawing a heart is 13/52, or 1/4.
The joint probability of these two events (events happening simultaneously) is
(1/4)(1/6) = 1/24
Answer:
The expression is not defined in a set of real numbers.
The square root of a negative number is not defined in the set of real numbers.

--------------------------
5(w-2)+6=3w-14
5w-10+6=3w-14
5w-4=3w-14
5w-3w-4=-14
2w-4=-14
2w=-14+4
2w=-10
w=-10/2
w=-5

-4x+2<2x-6
-4x-2x+2<-6
-6x+2<-6
-6x<-6-2
-6x<-8
6x<8
x<8/6
x<4/3
x>4/3
First, we need to understand the speed formula:
The time used = distance ÷ rate
In this case, the time needed would be:
5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6
When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:
=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)
Factorize 26 and 13,we get:
=2/5 x 6/1
= 12/5 ft or 2.4 ft
Therefore the answer is 12/5ft or 2.4ft.
Hope it helps!
