2. 24/10
3. 48/20
4. 96/40
Answer:
0.5
Step-by-step explanation:
We assume your function is

The distance formula can be used to find the distance from the point on the curve (x, f(x)) to the origin:
d^2 = (x)^2 + (f(x))^2 = x^2 + (4 -x)
Written in vertex form, this is ...
d^2 = (x -1/2) + 3.75
This has a minimum at x=1/2, so that is the x-coordinate of the point closest to the origin.
<em><u>Speed of skyler is 204 mph and speed of marcus is 212 mph</u></em>
<em><u>Solution:</u></em>
Skyler is 104 miles away from Marcus
Therefore,
Distance = 104 miles
They meet after 4 hours
Time taken = 4 hours
Let "x" be the speed of sklyer
Marcus travels 8 mph faster than skyler
Therefore,
Speed of marcus = 8 + x
They are traveling towards each other
Since they are traveling towards each other, we can add up their speeds
Speed = x + 8 + x = 2x + 8
<em><u>The distance is given by formula:</u></em>

Thus speed of skyler = x = 204 mph
Speed of marcus = 8 + x = 8 + 204 = 212 mph
Thus speed of skyler is 204 mph and speed of marcus is 212 mph
Answer: There is sufficient evidence to support the claim that the bags are under-filled.
Step-by-step explanation:
Since we have given that

Sample mean = 411
Standard deviation = 20
n = 9
So, the test statistic value is given by

At 0.025 level of significance,
critical value z = -2.306
since -2.306<-1.05
so, we will reject the null hypothesis.
Yes, there is sufficient evidence to support the claim that the bags are underfilled.
