The maximum profit for 1 tour would be $2650
if there are 90 seats and 10 deluxe seats must be sold, you have to multiply 10 times 25 which gives you 250.
if there are 90 seats, 10 must be deluxe (which is cheaper), and you are trying to find the max profit for 1 tour, then 80 of the seats must be economy seats.
to find out how much 80 economy seats would cost you need to multiply 80 times 30 which gives you 2400.
then you need to add the profit of 80 economy seats and 10 deluxe seats and that would give you $2650
and $2650 would be the max profit you could make for 1 tour.
Answer:
ok so this can be represented as
7.75x+675=1062.50
-675
7.75x=387.5
divide by 7.75
x=50
Hope This Helps!!!
Answer: Equation: 
or 
x is the cost of each shrub x = $10
Step-by-step explanation: Total bill = $62.50.
Subtract the cost of potting soil for $12.50 to find the cost of just the shrubs. 5x equals that amount
5x = 62.50 - 12.50
5x = 50 divide both sides by 5
5x/5 = 50/5
x = 10

Step-by-step explanation:
Hello!
X: Cholesterol level of a woman aged 30-39. (mg/dl)
This variable has an approximately normal distribution with mean μ= 190.14 mg/dl
1. You need to find the corresponding Z-value that corresponds to the top 9.3% of the distribution, i.e. is the value of the standard normal distribution that has above it 0.093 of the distribution and below it is 0.907, symbolically:
P(Z≥z₀)= 0.093
-*or*-
P(Z≤z₀)= 0.907
Since the Z-table shows accumulative probabilities P(Z<Z₁₋α) I'll work with the second expression:
P(Z≤z₀)= 0.907
Now all you have to do is look for the given probability in the body of the table and reach the margins to obtain the corresponding Z value. The first column gives you the integer and first decimal value and the first row gives you the second decimal value:
z₀= 1.323
2.
Using the Z value from 1., the mean Cholesterol level (μ= 190.14 mg/dl) and the Medical guideline that indicates that 9.3% of the women have levels above 240 mg/dl you can clear the standard deviation of the distribution from the Z-formula:
Z= (X- μ)/δ ~N(0;1)
Z= (X- μ)/δ
Z*δ= X- μ
δ=(X- μ)/Z
δ=(240-190.14)/1.323
δ= 37.687 ≅ 37.7 mg/dl
I hope it helps!
Answer:
hope this is right
Step-by-step explanation:
The majority of 65 degrees and up has more days than the others. But, That could change because we do not know how many day of the 12 year were 0- 32, 33 - 45, 46 - 64, and 65 degrees and up.
