The answer is D.6 do you want the work are are you good... I mean the easiest but yet most tedious way is to plug it in
Answer:
10 29/30
Step-by-step explanation:
Add just the integers first: 5 + 3 + 1 = 9
Convert the fractions so that they have the same demoninator. I chose 30 as the denominator, since 2*3*5 = 30
1/2 = 15/30
2/3 = 20/30
4/5 = 24/30
Add the fractions to find 59/30. That reduces to 1 29/30
Add (9+ 1 + 29/30) = 10 29/30 [ or 10.9666666 . . .
Answer:
d.45,54
Step-by-step explanation:
let the two numbers be x and y
x+y=9
y+x=9
let x=9-y
the square of either number minus the product of both digits plus the sqaure of the other digit is expressed as;
=21
substituting value of x we have
![(9-y)^{2} -(9-y)y+y^{2} =21](https://tex.z-dn.net/?f=%289-y%29%5E%7B2%7D%20-%289-y%29y%2By%5E%7B2%7D%20%3D21)
we have;
81 - 18y + y^2 - 9y + y^2 + y^2 = 21
3y^2 - 27y + 60 = 0, dividing through by 3 we get
y^2 - 9y + 20 = 0 using factorization
(y-5)(y-4) = 0
Two solutions
y = 5, then x = 4
y = 4, then x = 5
:
The two numbers would be 54, and 45
Answer: C f(x) = 16*(1/2)^ (x-1)
Step-by-step explanation:
You are dividing by 2 each time
This means that you are in the experiment group
It is common to choose a group of people to study the effect of certain things like the one given in this question. The selection of people is done after designing the sample size for a certain population. The design varies depending on whether the analysis is qualitative or quantitative.
The people who lie in the sample size actually contribute to the experiment are said to be part of it.
Therefore, if you are part of the study that is used to test the effectiveness of a new drug for treating the common cold. It means you are part of the experiment group.
