Answer:
Step-by-step explanation:
1. 48 x 5= 240
2. James minutes- 48 Alisa's- 240
3. 48 + 240 = 288
Equation: 48 + 5 (48)= 288
Answer:
(a) $180
(b) 25%
Step-by-step explanation:
(a) $126 = 30% of x; x is the total
so from this, you get an equation: 126 = 0.3x
solve the equation: x = 180; so the amount before
discount is $180
(b) You know the price of discount for the rice cooker is
180-126 which is $54
Then you subtract 54 from 64 to get the discount amount for the toaster
10/40 is 1/4 or 25%
It says Sandeep has twice as much as Sonia. Thus, let Sandeep's amount be 2x and Sonia's amount be x.
Now, together they have 150.
Thus, the equation;
x+2x=150
Now let's solve the equation;
3x=150
x=150/3
x=50
Thus, Sonia has 50
Answer:

Step-by-step explanation:
Given
Range = 0 to 8 years
Distribution: Uniform Distribution
Required
Determine the mean
The mean of a uniform distribution is calculated as thus:

Where a and b are the range of the distribution
In this case:

So, we have:
