artcher [175]

This is a problem of fundamental counting principle. In a sequence of events, the total possible number of ways all events can performed is the product of the possible number of ways each individual event can be performed. So here there is one car in each place so there 4 possible cars to get the 1st place, 3 possible car for the 2nd place, 2 possible cars for 3rd place and 1 for the 4th place. The 4x3x2x1 = 24 different order

Happy Store realizes a mark-up of PhP3,450 in selling TV sets. If its items are sold at a
Anna007 [38]

Answer:

Below is the answer.

Step-by-step explanation:

let s = the selling price.

the selling price presumably includes the cost plus the mark up plus the anticipated profit.

you have s = c + m + p

since m = 3450 and m = .4 * s, then you get:

.4 * s = 3450.

solve for s to get = 3450 / .4 = 8625.

your equation of s = c + m + p becomes:

8625 = c + 3450 + p

you don't know what p is supposed to be.

you don't know what c is supposed to be.

you need p to solve for c.

you need c to solve for p.

the best you can do is solve for c in terms of p, or solve for p in terms of c.

solving for c in terms of p gets you:

c = 8625 - 3450 - p which becomes c = 5175 - p

solving for p in terms of c gets you:

p = 8625 - 3450 - c which becomes p = 5175 - c.

you say that overhead expenses are 27% of the cost.

does this assume that overhead expenses are included in the cost.

regardless, if you don't know the cost, you can't solve for the overhead expenses.

i don't think you can solve this problem with the information given.

you might want to check to see if you're missing some information required to solve it.

A sample of 71 eggs yields a sample mean weight of 2.00 ounces. Assuming that the population standard deviation = 0.590 ounces,
Sauron [17]

Answer:

0.070 is the standard error of the mean weight in estimating a confidence interval estimate        

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} =  2.00 ounces

Sample size, n = 71

Alpha, α = 0.05

Population standard deviation, σ = 0.590 ounces

Formula for standard error =

S.E=\dfrac{\sigma}{\sqrt{n}}

Putting values, we get,

S.E = \dfrac{0.590}{\sqrt{71}} = 0.07002\approx 0.070

Thus, 0.070 is the standard error of the mean weight in estimating a confidence interval estimate
