SO from what I did was...
Since 24 x 3 = 72 , I did the same to 16.
16 x 3 = 48
But because instead of their being 3 teachers there is 1... What I did is just was to divide 48 / 2 which gave me the answer of 24...
So what I think the answer is...
There are 72 boys, 24 girls, and 1 teacher...
Unless I am just dumb and it would be 48 girls, but I think I did it right.
I hope I was able to help out.
Answer:
Step-by-step explanation:
Using first equation in the second gives you
x-3(-2x+1)=11
x+6x-3=11
7x-3=11
7x=14
x=2, making y=-2x+1 become
y=-2(2)+1
y=-4+1
y=-3 so the solution is the point
(2,-3)
Answer:
The correct option is
a) Yes, because (0.95)(0.92) = 0.874
Step-by-step explanation:
An event is independent if the following condition is satisfied
Therefore, since the the probability that the answer can be found in Google = 0.95 and the probability that the answer can be found in Answers = 0.92
The probability that the answer can be found on both websites,
= 0.874
We check, P(A) × P(B) = 0.95×0.92 = 0.874 = = 0.874
Therefore, the possibilities of finding the event on the two websites is independent.
What must be true is the expression will actually be adding 10 + (+ x), because of the two marks you have to make when subtracting by a negative.
The subtraction sign is also the negative sign. So in this case, the expression is also saying -x, which means there is two negative signs.
A double negative is a positive, so in this case the x will be turned to a positive integer.
If this is still too confusing, she can plug in a number to replace x. Let’s try it with -2:
Ex. 10 - (-2)= 12.
The two negative signs turn into one positive sign, AKA an addition sign. So, the above expression can be simplified as 10 + 2, or 12.
