In response to concerns about nutritional contents of fast foods, McDonald’s has announced that it will use a new cooking oil fo
r its french fries that will decrease substantially trans fatty acid levels and increase the amount of more beneficial polyunsaturated fat. The company claims that 97 out of 100 people cannot detect a difference in taste between the new and old oils. Assuming that this figure is correct (as a long-run proportion), what is the approximate probability that in a random sample of 1000 individuals who have purchased fries at McDonald’s (a) At least 40 can taste the difference between the two oils? (b) At most 5% can taste the difference between the two oils?

Answer:
inches or approximately 5.97 inches
Step-by-step explanation:
Use the cone volume formula: V = r²
The diameter is 8 inches, so the radius will be 4 inches.
Plug in the radius and volume, and solve for h
V = r²
100 = (4²)(
)
100 = 16
Divide each side by 16
=
Cross multiply and solve for h:
4h = 75
h =
So, the cone's height is or approximately 5.97 inches
Answer:
And since the time can't be negative we have that:
So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Step-by-step explanation:
For this case we have the function of the height in terms of the time givenby:
And we want to known when the rockect hit the ground and for this case we need to solve the equation
And as we can see we have a quadratic equation like this one:
Where:
And the general solutions are given by:
If we replace the values that we have we got:
And since the time can't be negative we have that:
So the answer for this case would be after 10.36 seconds the rocket will hit the ground
