Answer:
16.7%
Step-by-step explanation:
Please check below attachment for sample space table
Firstly, we have the total number of possible results as 12
From the 12, the probability of flipping a head is 6/12
Rolling either a 3 or a 5 is the sum of places we have both divided by the possible total of 12
we have this as ; 2/12 + 2/12 = 4/12
The term ‘AND’ means we have to multiply the two probabilities as follows;
4/12 * 1/2 = 1/6 = 0.1667
To the nearest tenth, we have this as 16.67% which is 16.7%
Well you need the mixture to start off by equalling $7, no matter what weight it is. The mean of two $6 candies and one $9 candy is $7 (6+6+9 = 21, 21/3 = 7)
So the ratio of 2:1 6$:9$ makes $7
Add 2 and 1 to get 3, 15/3 = 5, and because you're working out how much you need for the $9 candy, 5*1 (Because of the 2:1 ratio) is 5
She needs 5 pounds worth of the 9$ candy

Answer:
area=144 ft²
Step-by-step explanation:
width=x
length=4x
perimeter=2(4x+x)
60=2(5x)
60/2=5x
30=5x
x=30/5
=6
width=6 ft
length= 4(6)
=24 ft
area= length * width
=6*24
=144 ft²
