Answer:1.84
Step-by-step explanation: We can add this in a very easy way.
Step 1- We can put the 1 in the ones place as if there is no number before a decimal (which is the case for the first number) we can assume it is 0.
Step 2- We can then place the decimal point after the 1 and then put 0.8 since there are no more numbers that are at the tenths
Step 3- At the end we add the .04 (also known as 0.04) as there are no more places in both the numbers that are in the hundredths (and in 1.8, it can also be known as 1.80 as there are none!)
Hope this helps!
I would appreciate if you can mark me brainliest :)
The axis on symmetry is 3 the minimum is 9 and the y intercept it 9 if your teacher is talking about anything greater than or equal to 9 hope this helps god bless
Answer:
105 ways
Step-by-step explanation:
Because the order of selection does not matter, we know that we will be using a combination instead of a permutation.
₁₅C₂ = 15! / (2! * 13!)
= 15 * 14 * ... * 2 * 1 / 2 * 1 * 13 * 12 * ... * 2 * 1
= 15 * 14 / 2 * 1 (The 13! cancels out)
= 105
