Answer:

The correct answer is 5 2/15

Step-by-step explanation:

Since the numerators on both numbers are opposite, you have to go through an equation to make them equal.

4/5 and 1/3 don't have the same numerator. Because of this, you have to find the least common multiple.

5, 10, <u>15</u>

3, 6, 9, 12, <u>15</u>

Now that we found said number, we have to multiply the denominators so they match as well. How we do that is by multiplying the number by how many times the numerator has been multiplied to.

Since 5 had to be multiplied by 3 to get to 15, you would multiply 4 by three, giving you 12/15. Same goes with the other fraction, 3 times 5 got us 15, so we would multiply 1 by 5, giving us 5/15.

Now it's as simple as adding. 12/15 + 5/15 = 17/15, which will make 1 2/15. Add that to the whole numbers you have and you will get 5 2/15. (Note: You cannot simplify 2/15, so you leave it as is)

Answer:

0.3667

0.2727

Step-by-step explanation:

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

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

Alice and Bob are playing a game. Alice starts first. On Alice's turn, she flips a coin. If she gets a heads, she wins. If not,

trapecia [35]

Answer:

The probability that Alice wins the game= $\frac{1}{2}$

Step-by-step explanation:

We are given that Alice and Bob are playing a game .

We have to find the probability that Alice wins the game .

If Alice win when she gets head and lose when she gets tail.Bob wins when she gets tail and she lose when she gets head.

Total results in a coin=Head, tail=2

Number of head in a coin=1

Number of tail in a coin= 1

Probability is defined as the possibility of an event that occurred

$P(E)=\frac{Number\;of\;favourable\;cases}{total\;of\;cases}$

The probability that Alice wins the game= $\frac{Number\;of\;favourable\;cases}{Total\;number\;of\;cases}$

The probability that Alice wins the game= $\frac{number \;of \;heads}{Total\; results}$

The probability that Alice wins the game= $\frac{1}{2}$

3. Find the missing side lengths. Leave your answers as radicals in simplest form. Show your work to support

7nadin3 [17]

Answer: b=2(square root of 2) and a=4

Step-by-step explanation:

Since this is a 45-45-90 triangle we know that side b is equal to $b=2\sqrt{2}$ .

In a 45-45-90 triangle, the hypotenuse is equal to $x\sqrt{2}$ this means in order to find missing side length a, we have to multiply $(2\sqrt{2})(\sqrt{2})$ this will give us 4
