Answer:
The cashier received 100 envelopes
Step-by-step explanation:
let the number of stamps bought be x.
Cashier will receive 1/3 *x = x/3
Secretary will receive = 1/5 * x = x/5
Now we are told that the secretary received 40 fewer.
This means that the difference between the amounts they received is 40
Mathematically;
x/3 - x/5 = 40
2x/15 = 40
x = (15 * 40)/2 = 600/2 = 300
The cashier received x/3 = 300/3 = 100
Answer:
The percentage is 95.45%
Step-by-step explanation:
In this question, we are tasked with calculating the percentage of oranges weighing between a particular range.
To do this , we use the z-scores of both numbers in the range.
Mathematically, z-score can be calculated as (x - Mean)/SD
Thus we have P(3 <x < 7) = P( (3-5)/1 < z < (7-5)/1)
= P( -2 < z < 2)
Using standard score table, we have
P(-2<z<2) = 0.9545
The percentage is thus 9545/100 = 95.45
