Answer:
200 visitors went to screen 1.
125 visitors went to screen 2.
175 visitors went to screen 3.
Step-by-step explanation:
We will find number of visitors who went to screen 1 by finding 40% of 500 as we are told that 40% of 500 visitors went to screen 1.
Therefore, 200 visitors went to screen 1.
Now we will find number of visitors who went to screen 2. We are told that 25% of 500 visitors went to screen 2.
Therefore, 125 visitors went to screen 2.
Now we will find the number of visitors who went to screen 3 by subtracting combined number of visitors who went to screen 1 and screen 2 from total number of visitors.
Therefore, 175 visitors went to screen 3.
Answer:
C
Step-by-step explanation:
To see if an ordered pair is a solution, let's substitute the x and y-value into the equation and see if it check out. Let's go through each of the choices.
A) (0,2).
Substitute 0 for x and 2 for y. Thus:
Multiply and subtract:
So A is not correct.
B) (1,4)
Same thing:
Multiply and subtract:
So B is not correct.
C) (2,7)
Multiply and subtract:
So, our answer is C.
Let's do D just to double check:
D) (3,6)
Multiply and subtract:
Therefore, our correct answer is C.
And we're done!
Answer: Yes
Step-by-step explanation:
Answer:
f(19)=3/21-4=-3.857
Step-by-step explanation:
f(x)=3/(x+2)-sqrt(x-3)
f(19)=3/(19+2)-sqrt(19-3)
f(19)=3/21-sqrt(16)
f(19)=3/21-4
f(19)=-3.857
Answer:
x-2i
Step-by-step explanation:
Complex roots come in pairs, called complex conjugates
If you have a root a+bi, the other root is a-bi
Since you have one root x+2i, the other root is x-2i
