Answer:
1680 ways
Step-by-step explanation:
Total number of integers = 10
Number of integers to be selected = 6
Second smallest integer must be 3. This means the smallest integer can be either 1 or 2. So, there are 2 ways to select the smallest integer and only 1 way to select the second smallest integer.
<u>2 ways</u> <u>1 way</u> <u> </u> <u> </u> <u> </u> <u> </u>
Each of the line represent the digit in the integer.
After selecting the two digits, we have 4 places which can be filled by 7 integers. Number of ways to select 4 digits from 7 will be 7P4 = 840
Therefore, the total number of ways to form 6 distinct integers according to the given criteria will be = 1 x 2 x 840 = 1680 ways
Therefore, there are 1680 ways to pick six distinct integers.
Im pretty sure it’s going to be a, because when you divide by the -6 you’re supposed to switch the sign
Answer:
$7.76
Step-by-step explanation:
Let x be the amount he was making before the raise.
He had an increase of 3.1% of x added to x which resulted in a new salary of $8.00 per hour.
Mathematically:
x = $7.76
He was making $7.76 before the raise.
1/2
count all outcomes that have at least 2 H's
which is 4. There is a total amount of outcomes is 8.
There is 4/8 chance you will flip at least 2 heads
