Answer:

9/64

Step-by-step explanation:

So, we need to find the probability of drawing a blue marble the first time. There are a total of 8 marbles, and 3 blue marbles. So, the probability for the FIRST PULL will be:

3/8

Now, you REPLACE it meaning the value will stay the same. So now you just multiply.

3/8 * 3/8 = 9/64

Hope this helps !!

Answer:

9/64

Step-by-step explanation:

1 red marble, 3 blue marbles, and 4 green marbles = 8 marbles

1st draw:

P( blue) = blue / total = 3/8

We replace the marble

1 red marble, 3 blue marbles, and 4 green marbles = 8 marbles

2nd draw:

P( blue) = blue / total = 3/8

P(blue, replace, blue) = 3/8 *3/8 = 9/64

Answer:

45

Step-by-step explanation:

b and c are part of an 180 degrees angle.

You already have a 90 degrees angle

180-90=90

And since there are 2 angles

90/2=45

And b and c are vertical angles

Which of the following happens when unbalanced forces act on an object?
tigry1 [53]

Answer:

C. The object moves in the direction of the stronger force.

Step-by-step explanation:

A.) The object remains stationary.

- Cannot be since an outside force is applied, the net force is uneven, making the object move

B.) The object moves with the same velocity.

The object at rest has the velocity of 0m/s and since an outside force is exerted the object moved.

C.) This statement is correct since the object moved towards the direction the force is applied.

D.) Another wrong statement; unbalanced force is applied, the object moved.

Find the values of m and b that make the following function differentiable.
KengaRu [80]

f(x)=\begin{cases}x^2&\text{for }x\le2\\mx+b&\text{for }x>2\end{cases}

In order to be differentiable everywhere, f must first be continuous everywhere, which means the limits from either side as x\to2 must be the same and equal to f(2). By definition, f(2)=2^2=4, and

\displaystyle\lim_{x\to2^-}f(x)=\lim_{x\to2}x^2=4

\displaystyle\lim_{x\to2^+}f(x)=\lim_{x\to2}(mx+b)=2m+b

so we need to have 4m+b=4.

For f to be differentiable at x=2, the derivative needs to be continuous at x=2, i.e.

\displaystyle\lim_{x\to2^-}f'(x)=\lim_{x\to2^+}f'(x)

We then need to have

\displaystyle\lim_{x\to2}2x=\lim_{x\to2}m\implies\boxed{m=4}

Then

2m+b=4\implies\boxed{b=-4}
