The answer is in the image
The solution is in the following image
There are 6 outcomes 1,2,3,4,5,6
Total outcomes = 6
Outcomes when rolling a number is 4 or less = 1,2,3,4
Total outcome when rolling a number is 4 or less=4
Probability = required outcome/total outcome
=4/6
=2/3
Therefore probability = 2/3
(1 or 7) ; number of possible outcome = 2
(a, e, i, o, or u) ; number of possible outcome = 5
So,
Number of possible outcomes = 2 x 5
Number of possible outcome =10
Decrease in bikes sale = 650 - 572 = 78
%Decrease = (change)/old value * 100
%Decrease in sale = 78/650 * 100 = 12%
Decrease in sale = 12%
Total fabric purchased = 1 1/4 = 5/4
Fabric used = 3/4
Fabric left = 5/4 - 3/4
= 2/4
=1/2 yard
Volume of pool = 1472 m^3
Length = 36.8m
Breadth = 20m
We know,
Volume = l*b*h
1472 = 36.8 * 20 * h
h = 1472/736
h = 2m
Pool is 2m deep
Given eq k = 10t-19
Given t = -7
k = 10*(-7) - 19
= -70 -19
=-89
