The fundamental theorem of calculus tells you

$\displaystyle \frac{d}{dt}\left(\int{\frac{\cos{t}}{t}\,dt}\right)=\frac{\cos(t)}{t}$

Jamie has a bag containing purple, pink, yellow, and blue marbles. There are a total of 40 marbles in the bag. Jamie randomly se

Ad libitum [116K]

Answer:

1 pink marble

Step-by-step explanation:

If Jamie selected 10 times the pink marble in a total of 420 tries, we can assume that the proportion of pink marble in the total number of marbles is:

10 / 420 = 1/42

So to predict a good number of pink marbles in the total 40 marbles, we just need to multiply the 40 marbles by the proportion found above:

pink marble = 40 * (1/42) = 0.9524

As this number needs to be a whole number, a good assumption is that there is 1 pink marble in the 40 marbles.

Find the value of b. Express the answer as a simplified radical.

Mama L [17]

Here three sides of a right angled triangle given.

The three sides are b, 8 and 14.

The side with length 14 is the hypotenuse here. We have to find the side of length b.

To get b, we will use Pythagoras theorem here.

By using Pythagoras theorem we can write,

$c^2=a^2+b^2$ , where c is the hypotenuse.

So here we can write,

$14^2=8^2+b^2$

$196 = 8^2+b^2$

$196=64+b^2$

To solve it for b, now we have to move 64 to the left side by subtracting it from both sides.

$196-64 = 64+b^2-64$

$196-64 = b^2$

$132=b^2$

Now to find b, we have to take square root to both sides. We will get,

$\sqrt{132}= \sqrt{b^2}$

$\sqrt{132} =b$

$b= \sqrt{(4)(33)}$

$b= (\sqrt{4})(\sqrt{33})$

$b= 2\sqrt{33}$

We have got the required answer for the side b.
