The sum of two numbers is −102. One number is 62 less than the other. Find the numbers.

Allisa [31]

Answer:

x = -20

y = -62

Step-by-step explanation:

Suppose x and y two number and such that :

their sum = -102
and y is 62 less than x

Which means :

x + y = -102

x - y = 62

then

x + y = -102

x = y + 62

then

x + y = (y+62) + y = -102

then

2y + 62 = -102

then

2y = -164

then

y = -164/2 = -82

therefore

x = y + 62 = -82 + 62 = -20

A combination lock requires a user to select three numbers to unlock it, where all three numbers are between 1 to 30, inclusive,

Sonbull [250]

Answer:

$\frac{1}{270}=0.00370$

Step-by-step explanation:

As the numbers are only between 1 and 30

Total number of possible combinations = 30×30×30 = 27000

If there are 100 attempts then

$\text{P (someone guesses correct)}=\frac{\text{Number of attempts}}{\text{Total number of possible combinations}}\\\Rightarrow \text{P (someone guesses correct)}=\frac{100}{27000}\\\Rightarrow \text{P (someone guesses correct)}=\frac{1}{270}=0.00370$

∴ Probability someone can guess the correct combination given 100 attempts is $\mathbf{\frac{1}{270}=0.00370}$
