The equation c=2.5t represents the cost,(c),for (t) ticket to the school play. Does a value of 3.5 for (t) make sense in this si
2 answers:
Answer:
No, a value of t = 3.5 does not make any sense in this scenario.
Step-by-step explanation:
We are given the following information in the question:
where c is the cost and t is the number of tickets.
No, a value of t = 3.5 does not make any sense in this scenario.
Because the number of tickets are discrete value and cannot have decimal values.
The continuous variable can be expressed in decimal form.
Hence, t cannot have a value of 3.5
Although, cost is a continuous variable and may have decimal values.

Answer:
No, the on-time rate of 74% is not correct.
Solution:
As per the question:
Sample size, n = 60
The proportion of the population, P' = 74% = 0.74
q' = 1 - 0.74 = 0.26
We need to find the probability that out of 60 trains, 38 or lesser trains arrive on time.
Now,
The proportion of the given sample, p =
Therefore, the probability is given by:
P
P
Therefore, Probability of the 38 or lesser trains out of 60 trains to be on time is 0.0298 or 2.98 %
Thus the on-time rate of 74% is incorrect.
The horizontal distance between Carl and the rock at sea is approximately 60.62ft.
Data;
- Angle = 30 degree
- Opposite = 35
- Adjacent = x
Given the angle of depression from his point to the sea, we can use trigonometric ratio to calculate for the horizontal distance from his location to the bottom of the sea.
SOHCAHTOA
Since we have the value of angle and opposite and we need to calculate the adjacent side of the right-angle triangle, we can use the tangent of the angle to this effect.
The horizontal distance between Carl and the rock at sea is approximately 60.62ft.
