True
Step-by-step explanation:
Answer:
The number of marbles Richard has 24 and John has 6.
Step-by-step explanation:
Richard has four times as many marbles as john.
If Richard have 18 to John they would have the same number.
Now, to find number of marbles each has.
Let the marbles of John be
.
And the marbles of Richard be ![4x.](https://tex.z-dn.net/?f=4x.)
According to question:
![4x=x+18.](https://tex.z-dn.net/?f=4x%3Dx%2B18.)
<em>Subtracting both sides by
we get:</em>
![3x=18.](https://tex.z-dn.net/?f=3x%3D18.)
<em>Dividing both sides by 3 we get:</em>
![x=6.](https://tex.z-dn.net/?f=x%3D6.)
<u><em>Marbles of John</em></u><em> =
</em>
<u><em>Marbles of Richard</em></u><em> =
</em>
Therefore, the number of marbles Richard has 24 and John has 6.
Answer:
0.3667
0.2727
Step-by-step explanation:
a)
P (Blue) = P (large and Blue) + P (mid and Blue) + P (small and Blue)
P (Blue) = (0.5 * 0.2) + (0.4*7 / 12) + (0.1* 1 / 3)
P (Blue) = 0.3667
b)
Conditional Probability:
P (Large / Blue ) = P (large and Blue) / P ( Blue)
P (Large / Blue ) = 0.5*0.2 / 0.36667
P (Large / Blue ) = 0.2727
The answer is y=3 since there is no slope so the value of x will not affect your graph
No, they are not equivalent because 8x + 5x equals to 13x
