Answer:
Step-by-step explanation:
so she earns 9.75% commission on each mattress
turn ur percent to a decimal....and multiply that by the cost of the mattress and that will give u her commission.
0.0975(2400) + 0.0975(3200) + 0.0975(1900) + 0.0975(800) =
234 + 312 + 185.25 + 175.50 =
906.75 <=== her total commission
Answer:
a. 0.45 b. 1
Step-by-step explanation:
We will be using Poisson Approximation of Binomial because n = 80,000 is large and probability (<em>p) </em>is very small.
We calculate for (a) as follows:
The probability that both partners were born on April 30 is
<em>p </em>= 1/365 X 1/365
<em>p </em>= 1/133,225
<em>p </em>= 0.00000751
Using Poisson Approximation, we have:
λ = n<em>p</em>
λ = 80,000 X 0.00000751
λ = 0.6
We use λ to calculate thus:
P (X 1) = 1 - P ( X = 0)
= 1 - e^-λ
= 1 - e^-0.6
= 0.451
There is a 45.1% probability that, for at least one of these couples, both partners were born on April 30.
(b) To calculate the probability that both partners celebrated their birthday on the same day:
<em>p </em>(same birthday) = 365 X 1/365 X 1/365
= 1/365
λ = n<em>p</em>
λ = 80,000 X 1/365
λ = 219.17
P (X 1) = 1 - P ( X = 0)
= 1 - e^-λ
= 1 - e^-219.17
≈ 1
There is almost 100% probability that, for at least one of these couples, both partners celebrate their birthday on the same day of the year.

Convert 5 1/11 to an improper fraction.
Exact Form:
-56/11
Decimal Form:
-5.09
Mixed Number Form:
-5 1/11
If you would like to know the truck's value after 2 years, you can calculate this using the following steps:
8% of 32,500 = 8% * 32,500 = 8/100 * 32,500 = 2,600
32,500 - 2,600 = 29,900
8% of 29,900 = 8% * 29,900 = 8/100 * 29,900 = 2,392
29,900 - 2,392 = 27,508
The correct result would be 27,508.
Jim owns 48 cars.
4:3 as x:36
36/3 is 12, so the scale is 12.
x is 4*12 = 48
