The value of the stock ABC over a period of 47 days is $4474.03.
<h3>What is a scatterplot?</h3>
A scatterplot is used to show the relationship between two variables. The variables are plotted on Cartesian axes.
First, we must determine the fitness of the line to show if it is linear. We can get this from r^2 = (0.9948)^2 = 0.9896. This value is close to one hence the line is linear.
Thus;
y= 94.38x+ 38.17 and x = 47 hence
y= 94.38(47)+ 38.17
y = $4474.03
Missing parts:
Equation y = 94.38x + 38.17 fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9948. How much do you think ABC will be worth at x = 47 days?
A.$94.38 B
.$4474.03 C
.$4752.31
D.$38.17

sum is addition and product is multiplication
Answer:
(a) The probability distribution is valid.
(b) The histogram is attached below.
(c) The mean is 33.47.
Step-by-step explanation:
(a)
A probability distribution is valid if:
- P (X = x) ≥ 0 for all values of <em>x</em>.
- ∑ P (X = x) = 1
From the probability distribution table it can be seen that the probability for all <em>x</em> is greater than 0.
Compute the sum of all probabilities as follow:
Thus, the probability distribution is valid.
(b)
The histogram is attached below.
(c)
The formula of mean of a discrete probability distribution is:
Compute the mean as follows:
Thus, the mean is 33.47.
The answer is c or the answer is A
