Once at (-3,-10) is where they would intersect
The equation for profit is expected to be
daily profit = (profit on plate)*(number of plates) +(profit on cup)*(number of cups)
We are told that
profit on plate = k
profit on cup = k-1
Matching these to the expression above, we find
x = number of plates
y = number of cups
You are asked what y represents. It is
A. The number of cups sold in one day.
Answer:
Hey there so this looks harder then it really is. All you need to do is this..
700x5.5%= 38.50
then times that by 4 to get your total over the 4 years.
Simple interest=154
Step-by-step explanation:
Answer:
0.7448
Step-by-step explanation:
P(A1) =0.95
P(A2) =0.98
P(A3) =0.8
We have to find P( all three components function properly)=P(A1∩A2∩A3).
We know that the these three events are independent so,
P( all three components function properly)=P(A1∩A2∩A3)=P(A1)*P(A2)*P(A3)
P( all three components function properly)=P(A1∩A2∩A3)=0.95*0.98*0.80
P( all three components function properly)=P(A1∩A2∩A3)=0.7448
So this is what's known as a combination. a combination is a group where the order does not matter. to solve a combination, you use this equation:
n! / (r! *(n-r)!)
n is the total number of objects being sorted (8)
r is the group you need to sort them into (4)
(i know it's 2 groups of 4 but if you solve this for 1 group, the other group is automatically made of the remaining kids)
definition of !:
a number with a ! means 1*2*3...*that number (so that number multiplied by every number smaller than it all the way to one)
so we put 8 and 4 in this equation:
8! / (4! *(8-4)!)
simplify:
8! / *(4! 4!)
multiply out:
(8*7*6*5*4*3*2*1) / (4*3*2*1 * 4*3*2*1)
and put that in your calculator
you will get 70
your answer is 70
