Answer:
Her weekly expenses amount to $25.
Detailed reasoning:
Given: Jessica earns commissions for every sale but must cover her own spending costs.
She expresses her income function as , where x represents the number of doors she approaches in a week and E(x) denotes her weekly earnings in dollars.
To determine: What are plausible meanings for the y-intercept in Jessica's earnings function?
Working it out:
x symbolizes the doors knocked per week
E(x) reflects her weekly total earnings in dollars.
Calculating the y-intercept:
Set x = 0
Given that E(x) is the net earning after expenses,
the value 25 corresponds to her weekly expenses.
Since she is responsible for covering costs,
if she makes zero sales, these expenses still apply.
Therefore, the y-intercept realistically represents her $25 weekly expenses.

Step-by-step explanation:
Based on the fact that Seymour’s age is double that of Cassandra. If 16 is added to Cassandra’s age and 16 is deducted from Seymour’s age, both will be of the same age.
We need to determine their current ages.
Let Cassandra's current age be x years
Given that Seymour is twice as old as Cassandra
Thus, Seymour's current age=2x years
According to the problem, if 16 is added to Cassandra's age and 16 is subtracted from Seymour's age, their ages will equal each other.

Answer:
The most likely length of the line is 69.4012 meters.
The calculated standard deviation amounts to 0.0032 meters.
Step-by-step explanation:
In the problem, the following values are provided:
69.401, 69.400, 69.402, 69.396, 69.406, 69.401, 69.396, 69.401, 69.405, 69.404
Formula:
where represent data points,
is the average, and n indicates the count of observations.
The most likely length of the line is 69.4012 meters.
Sum of squares of differences = 0.0001016
The calculated standard deviation amounts to 0.0032 meters.
