Answer:
"Susanna starts out slower than Anita but still wins the race."
Step-by-step explanation:
The distance of the race is "5 miles". We can see the "endpoint" of each race's graph and corresponding y value. That is 5 miles.
Now, we look at corresponding "x" value, that is the time it took.
For Susannah, it is 5.5 minutes
For Anita, it is 7 minutes.
So, clearly, Susanna wins the race.
Now, we look at the "slopiness" of each person's line graph. This is the speed at which they were going.
The red line (Susanna) is quite sharper than anita, so her speed (rate) is more. But initially, we can see that the blue line (Anita) was sharper than Susanna but later gradually fell. So we can say:
Susanna started out slower than Anita, but ultimately won.
From the answer choices, last one is right -- "Susanna starts out slower than Anita but still wins the race."
Answer:
4(x-1/2)^2+0
Step-by-step explanation:
I used the formula (b/2)^2
Answer:
1) 
2) 49.225
3) 
Step-by-step explanation:
1) To find the expected value of the dice we can use the following equation:
So in our problem the values x will be: 1/1, 1/2, 1/3, 1/4, 1/5 and 1/6 and the probavility for all values is 1/6 so the expected values will be:
2) To find the variance of the expected values we can use the equation:
So for our problem will be:
3) To find the expected value of the dice we can use the following equation:
So in our problem the values x will be: 1, 2, 3, 4, 5 and 6 and the probavility for all values is 1/6 so the expected values will be:
