Answer: It means Aria's vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.
Step-by-step explanation:
Since, Here d represents distance along the trail.
And, V(d) represents the vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.
If the distance along the trial is 3 km.
That is, d = 3
Then the vertical distance she walked from the top of the valley = V(3)
But According to the question,
V(3) < 3
Her vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.
In other words, For going 3 km along the trail her vertical distance from the top of the valley is less than 3.
Answer:
y = -5x - 2
Step-by-step explanation:
y = mx + b
m = -5
b = -2
The value of the digit 5 in this number is 50 because 5 is in the tenth place.
Answer:
So the answer for this case would be n=16 rounded up to the nearest integer
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation

represent the margin of error desired
The margin of error for the true mean is given by this formula:
(a)
And on this case we have that ME =0.03 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence level is 80%, the significance would be
and
the critical value for this case is
, replacing into formula (b) we got:
So the answer for this case would be n=16 rounded up to the nearest integer
Answer:
the right answer is option A. 40°
Step-by-step explanation:
angle BAC= angle BAD - angle CAD
= 120° - 80°
= 40°
