Answer:
R: {y<=2}
Step-by-step explanation:
We can identify the range by looking at all possible y values or the result after you input an x in the g(x) function. We see that in the g(x) function, the vertex of the quadratic graph lies on (0,2) when we graph it. Thus, any possible y value must be less than or equal to (0,2) because the slope is pointing down due to the negative coefficient attached to the x, making it have a maximum.
Thus all y values or the range of g(x) must be {y<=2}

Answer:
$8.75
Step-by-step explanation:
$35 x .25 = $8.75 (Amount Dara has saved)
It would be 7 divided by 11( note: always divide the top by the bottom)
Answer:
0.3888
Step-by-step explanation:
To solve the exercise we need a neutral time, so we define at 12:00 as time 0.
If the man arrives in a uniformly distributed time between 11:40 and 12:10, the time is distributed from -20 to 10.
If the woman arrives in a time evenly distributed between 11:45 and 12:20, the time is distributed from -15 to 20.
Assuming that each one arrives at 12: X and 12: Y for men and women, then the space of our time is defined as
Man [-20,10]
Woman [-15,20]
So,
Then,
The probability of finding an arrival less than 5 minutes is
1 2/5 x 3 4/5 = 5.32 -- with calculator
----------------------------------------------------
You can change mixed fractions to improper fractions.
1 2/5 = 1 x 5 + 2 = 7 = 7/5
3 4/5 = 3 x 5 + 4 = 19 = 19/5
7/5 x 19/5 = 133/25 = 5.32
-----------------------------------------
To make sure you can then turn the improper fractions to decimals.
7/5 = 1.4
19/5 = 3.8
1.4 x 3.8 = 5.32
--------------------------
Whenever I get mixed fraction questions, I always check it in these different excess ways just to make sure :3 Hope it helped..
