Answer: 13.9

Step-by-step explanation:

Hey there!

So, when finding missing parts of an equation, in this case

-6.8 + 2.6 + x = 9.7

First add

-6.8 + 2.6 = -4.2

Then -4.2 + x = 9.7

To find x, add 4.2 and 9.7 and you get 13.9

Plug 13.9 into the equation for x to check if you are correct

-6.8 + 2.6 + 13.9 = 9.7

-6.8 + 16.5 = 9.7

9.7 = 9.7 ✔

Your solution checks

Hope this helps

-6.8 + 2.6 = -4.2
-4.2 + x = 9.7
x = 9.7 + 4.2
x = 13.9

Answer:

$Probability = 0.006033$

Step-by-step explanation:

Given

$Tries = 1000000$

Required

Determine the probability of 6 different lower case letters (Question continuation)

There are 26 lower case letters.

The first can be any of letters 26

The second can be any of letters 26 - 1

The third can be any of letters 26 - 2

The fourth can be any of letters 26 - 3

The fifth can be any of letters 26 - 4

The sixth can be any of letters 26 - 5

Number of selection is:

$Selection = 26 * (26 - 1) * (26 - 2) * (26 - 3) * (26 - 4) * (26 - 5)$

$Selection = 26 * 25 * 24 * 23 * 22 * 21$

$Selection = 165765600$

The probability is:

$Probability = \frac{Tries}{Selection}$

$Probability = \frac{1000000}{165765600}$

$Probability = 0.00603261472$

$Probability = 0.006033$ --- approximated

The difference of the square of a number and 28 is equal to 3 times that number

Pepsi [2]

Answer:

- 4, 7

Step-by-step explanation:

Let the required number be x.

Therefore, according to the given condition:

${x}^{2} - 28 = 3x \\ {x}^{2} - 3x - 28 = 0 \\ {x}^{2} - 7x + 4x - 28 = 0 \\ x(x - 7) + 4(x - 7) = 0 \\ (x - 7)(x + 4) = 0 \\ x - 7 = 0 \: or \: x + 4 = 0 \\ x = 7 \: or \: x = - 4 \\$
