A 5-digit combination lock with digits 0-9 can be opened only if a correct combination of digits is chosen. Find the probability

stepladder [879]

A. 5 digit code with digits from 0-9 with no repetition.

Choices for 1st digit=10, and choices for successive digits are 9,8,7,6.

Probability of guessing it correctly on first try is

1/(10*9*8*7*6) = 1/30240

B. If zero is not in the combinations, then the domain of digits is 1-9, or 9 choices. Digits can repeat means every digit in the code has 9 choices.

Number of arrangements = 9^5 = 59049

Probability of guessing at first try = 1/59049

Line g passes through points (1, 1) and (10, 9). Line h is perpendicular to g. What is the

Sauron [17]

Answer:

$\bold{The~slope~of~line~h~is~-\frac{9}{8}. }$

Step-by-step explanation:

Hi there!

First, let's calculate the slope of line g.

$\displaystyle\frac{y2-y1}{x2-x1}$

$\displaystyle\frac{9-1}{10-1} \\
\displaystyle\frac{8}{9}$

So, the slope of line g is $\displaystyle\frac{8}{9}$

Now let's identify the slope of line h.

We are given that line h is perpendicular to line g.

Now, perpendicular lines have slopes that are opposite reciprocals.

This means we take a number, flop it over, and change its sign.

The slope of line g is

$\displaystyle\frac{8}{9}$

Now, we flop it over:

$\displaystyle\frac{9}{8}$

Then, we change its sign:

$\displaystyle-\frac{9}{8}$

Thus, $\displaystyle-\frac{9}{8}$ is our final answer.

Hope it helps! Enjoy your day! (:

If the spinner is spun, what is the probability that the spinner will land on a multiple of 4

vesna_86 [32]

In the usual spinner that we have, the circular figure is divided into 8 equal parts. Each of which is numbered from 1 to 8. There are two of these numbers that are multiple of 4 (4 and 8). Now, the probability that the spinner will land on a multiple of 4 is equal to 2/8 or also equal to 1/4 or 0.25.
