Answer: in order to qualify, the time must be at least 15.93 minutes
Step-by-step explanation:
Let x be a random variable representing the average response times of fire departments to fire calls. Since it follows a normal distribution, we will determine the z score by applying the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
From the information given,
µ = 12.8 minutes
σ = 3.7 minutes
in order to qualify for the special safety award, the probability value would be to the right of the z score corresponding to 80%
The z score corresponding to 80% on the normal distribution table is 0.845
Therefore,
0.845 = (x - 12.8)/3.7
0.845 × 3.7 = x - 12.8
3.13 = x - 12.8
x = 12.8 + 3.13 = 15.93

Answer: it’s a Constant!
Step-by-step explanation:
Answer:
Oh okayy
Step-by-step explanation:
Answer:
A- b: the y value when y changes; the point where a line crosses the v-axis
B- m: What happens to y when x is one; the ratio of the y change to the x change
C- k: The y value when x is zero b x increases by one
Step-by-step explanation:
If this is about slope intercept form as i think it is
C sounds a little bonkers in this case though because when y is zero then x increases by one
