Answer:

15(radius) x 3.14 (pi)x 2(just always here when finding circumference) = 94.2

C is your answer. If we do part of the formula, 15 x 2 = 30, now we just need to multiply by pi. and 30π would be your answer.

Step-by-step explanation:

15 seems to be your radius, so lets just use the circumference formula!

C would most likely be your answer, it is partially done. 15 x 2 = 30, but now we multiply by pi and it says so in answer c.

There are 10 marbles in a bag. 3 are red, 4 are blue, 2 are green, and 1 is yellow. You plan to draw 2 marbles from the bag with

schepotkina [342]

<h2>Probability that the second marble will be blue is 0.44</h2>

Step-by-step explanation:

There are 10 marbles in a bag. 3 are red, 4 are blue, 2 are green, and 1 is yellow.

Total number of marbles = 10

Given that first marble is yellow.

New total number of marbles = 10 - 1 = 9

Now we have 3 are red, 4 are blue, 2 are green.

Number of blue marbles = 4

We need to find drawing probability of blue marble from 9 marbles.

Let the probability be, p

$p=\frac{\texttt{Total blue marbles}}{\texttt{Total number of marbles}}\\\\p=\frac{4}{9}\\\\p=0.44$

Probability that the second marble will be blue is 0.44

ludmilkaskok [199]

Answer:

choosing one card from a deck and then choosing one card from another deck.

Step-by-step explanation:

These two actions are independent of each other. There is the same probability of choosing a card from any of those decks.

Let's say the decks are of 52 cards for example.

If you select one from the first deck , there are still 52 cards on the second.

Having selected from one, did not affect the other.

I hope this helped. I am sorry if you get this wrong.

What’s is the slope line ?

Elena L [17]

Answer:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Step-by-step explanation:

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope,
