There are 30 blue balls, 40 red balls, and 30 white balls in a bag of balls. What is the conditional probability of choosing a b

natulia [17]

Answer: So, the probability will be

$P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}$

Step-by-step explanation:

Since we have given that

Number of blue balls =30

Number of red balls = 40

Number of white balls = 30

Since there are 100 balls in total ,

As we have given that there is no white ball chosen.

So, only 70 balls are left with us , from which we choose a blue ball

So, the probability will be

$P( \text{getting a blue ball })=\frac{30}{70}=\frac{3}{7}$

Solve the equation <br> (If possible please show work)

deff fn [24]

Answer:

$x=-3$

Step-by-step explanation:

So we have the equation:

$-2(-x-4)+3=-7-4x$

First, distribute the left side:

$-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x$

Add values on the left side:

$2x+11=-7-4x$

Add 7 to both sides. The right side cancels:

$(2x+11)+7=(-7-4x)+7\\2x+18=-4x$

Subtract 2x from both sides. The left side cancels:

$(2x+18)-2x=(-4x)-2x\\18=-6x$

Divide both sides by -6:

$(-6x)/-6=18/-6\\x=-3$

Therefore, x equals -3.

Use the digits 1,2,3 and 4 once each to get the largest answer possible

sukhopar [10]

Answer:

4,321

Step-by-step explanation:

This is the answer because:

1) We know that if the number has to be big therefore, we have to put 4 in the thousands place because 4 is bigger than 3, 2, and 1

2) Next, 3 is the other biggest number, for that reason 3 is in the hundreds place

3) Then, 2 is the other bigger number; therefore, the tens place is 2

4) Finally, the last number remaining is 1, which is in the ones place

Therefore, the answer is 4,321

Hope this helps!
