<u>Answer:</u>

The correct answer option is 4/11

<u>Step-by-step explanation:</u>

We know that the word 'probability' has 11 alphabets.

We are to find to find the probability of getting a 'b' or an 'i' from this word.

Probability of getting a b = \frac{2}{11} (since there are 2 b's in probability)

Probability of getting an i = \frac{2}{11} (since there are 2 i's in probability)

Probability of getting 'b' or 'i' = \frac{2}{11} + \frac{2}{11} = \frac{4}{11}

4/11



First, count how many letters are in “probability”. There are 11 letters.

Now, count how many b’s there are in the word. There are 2.

Then, count how many i’s are in the word. There are also 2.

Add the b’s and i’s together to find that there are 4 of them.

There are 4 possible ways to choose a “b” or an “i”, and there are 11 possible letters to choose from. So, the probability is 4/11.

A positive real number is 2 more than another. If the sum of the squares of the two numbers is 42, find the numbers.
Brilliant_brown [7]

Answer:

Step-by-step explanation:

From the first sentence x (the number) is 2 more than another number (y). So, x+2=y. The sum of the squares of the two numbers is 42, meaning that \\ (x+2)^{2}+y^{2}=42. First, we square root the ENTIRE equation to get rid of the square. If you do one thing to one side, you have to do it to the other. After this, we have x+2+y=\sqrt{42}. Now, we subtract 2 from the other side to isolate the variable. You can isolate either one but normally I go for x. Now we have x+y=\sqrt{42}+2. Now, we want to get y to the other side so we subtract it from the left side and the right side which gives us x=-y+\sqrt{42}+2. now we know what X is equal to. Now we plug in x for \\ (x+2)^{2}+y^{2}=42, which gives us          (-y+\sqrt42}+2+2)^{2}+y^{2}=42. Now we only have one variable which is what we want. Next, we square root the entire thing to get rid of the squares, which gives us -y+\sqrt{42}+4+y=\sqrt{42}. I got lost in my work. I must have done something wrong I cant find out. If anyone wants to pick up where I left off go ahead but there's a timer and I have one minute left. I cant finish the problem in a minute. I'm sorry and hopefully I lead you somewhere.

What is the sum or difference 6x^7+8x^7
s344n2d4d5 [400]
Answer: 14x^7

You add the coefficients (numbers to the left of the variable terms) to get 6+8 = 14 which is the coefficient of the final answer. The x^7 stays the same. It's like saying "we have 6 apples added to 8 apples, so there are 14 apples overall". Replace "apples" with "x^7" and it's the same idea.

−2∣5w−7∣+9=−7 how do i get the second answer
r-ruslan [8.4K]
To calculate the answers for an expression with an absolute value term. First, we isolate the one with the absolute value. 

<span>−2∣5w−7∣+9=−7
</span><span>−2∣5w−7∣=−7-9 = -16
</span>∣5w−7∣=8

<span>Then, set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.
</span>
5w=8+7
5w = 8-7

The answers are:

w = 3
w = 1/5
