Answer:
C
Step-by-step explanation:
the explicit formula for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
from the recursive formula in the form
= + d
given
= - 7
with d = - 7 and a₁ = 4 , then explicit formula is
= 4 + (n - 1)(- 7)
Answer:
The probability that it takes Annie between 39 and 40 minutes given that it takes less than 44 minutes for her to make dinner is 0.04.
Step-by-step explanation:
Let <em>X</em> = amount of times (in minutes) it takes Annie to make dinner.
The random variable <em>X</em> follows a continuous Uniform distribution with parameters <em>a</em> = 19 minutes and <em>b</em> = 49 minutes.
The probability density function of continuous Uniform distribution is:
Compute the value P (39 < X < 40 | X < 44) as follows:
Thus, the probability that it takes Annie between 39 and 40 minutes given that it takes less than 44 minutes for her to make dinner is 0.04.
