What is the probability of rolling 7 or a 5 on a single 10 sided dice

Mathematics

Here a "success" is "obtaining a 7 or a 5."  Assuming that the 10-sided die is marked {1, 2, 3, ... , 9, 10}, there are 2 ways in which to get a "success" out of 10 possible outcomes.  Thus, P(5 or 7) is 2/10, or 1/5, or 02.

I need help with number 8
murzikaleks [220]
Since we know what he earns hourly, and his sales, we can figure out his full gross pay for the week.
As so:

We can set up an equation like this:
<em>h</em> = hours
<em>s</em> = sales
9.60h + 5%s

Now, we substitute.
9.60(35) + 5%(230)

Next, solve.
336.00 + 11.50
$347.50

$347.50 was Glen's gross pay for the week.

Hope I could help! If my math is wrong, or I did not provide the answer you were looking for, let me know! However, if I did well, please consider marking as <em>Brainliest!
</em>Have a good one!

Find the solution of Equation: (3x-2)/(x+3)-1=(3x-3)/(x+1)-2
saveliy_v [14]

Answer:

Solution tends to infinity

Step-by-step explanation:

Given the expression

(3x-2)/(x+3)-1=(3x-3)/(x+1)-2

This can also be expressed as;

(3x-2)/x+2 = 3x-3/x-1

3x-2/x+2 = 3(x-1)/x-1

3x-2/x+2 = 3

Cross multiply

3x-2 = 3(x+2)

3x-2 =3x+6

Collect like terms

3x-3x =6+3

0x = 9

x = 9/0

x = infinity

Hence the expression had no solution. It tends to infinity
