Answer:
$120.
Step-by-step breakdown:
Libby sold $60 worth of vegetables at the farmer's market.
Jess sold 3/4 of what Libby sold, so let's calculate that: 3/4 of 60.
Thus, Jess made $45.
Now, Stephanie sold one-third of Jess's total, necessitating the calculation of one-third of 45.
This means Stephanie sold $15 worth of vegetables.
Putting together Libby's, Jess's, and Stephanie's sales, we arrive at the collective total earned by all three.
Consequently, their total sales amount to $120.
Answer:
A one-sample t-test is suitable in this scenario
Step-by-step explanation:
The hypothesis test is focused on the mean when the population standard deviation isn't known. We will estimate the population standard deviation using the sample equivalent, s, to inform the calculation of the test-statistic.
Response:
We define a line L.
In a two-dimensional space, a line can be expressed as follows:
y = a*x + b
where 'a' denotes the slope and 'b' represents the y-intercept.
To determine the slope for a line passing through points (x1, y1) and (x2, y2), the formula is:
a = (y2 - y1)/(x2 - x1).
Using one of these points will help to find the value of 'b'.
Once we have the line's equation:
y = a*x + b
we can substitute in a specific point (x, y)
to verify if the equation holds true. If it does, that point lies on the line L.
The solution is C. Let’s start by identifying the equations without inequalities. Since there's a dotted line at y = 1, options A and B can be disregarded. Dotted lines indicate exclusivity, so they do not encompass the = sign. Therefore, the answer must be C.
