Answer:
Step-by-step explanation:
<u>Given:</u>
and
<u>Find g(f(x)), substitute the value of f(x) into equation:</u>
- g(f(x)) = g(2x + 1) = (2x + 1) - 3 = 2x - 2
Since Q and R are independent, this means P(Q and R) = P(Q)*P(R)
<span>P(Q and R) = P(Q)*P(R)
</span><span>P(Q and R) = (4/5)*(4/11)
</span><span>P(Q and R) = (4*4)/(5*11)
</span>P(Q and R) = 16/55
Answer:
7/165
Step-by-step explanation:
This is a mixed recurring decimal (the zero is not repeating)
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
Now ,the denominator:
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242......
Her total distance (so 265 miles) over the number of hours she drives will give miles per hour.
265miles/5hours=53 miles/hour
Answer:
40% profit
Step by step Explanation:
Profit percentage
=( profit/cost price) * 100
0.2 = profit/cost
10+15+20+25+30= 100
Let's assume the cost price of the items is $1 each
Cost price total= $100
Profit made when buyer of 20 toffe didn't say was
0.2=profit/cost
0.2*100 =$20
If the$ 20 paid.
Total profit = $40
So percentage profit now
40/100 * 100 = 40%
