Answer:
c. Skewed-right with a mean of $5.25 and a standard error of$0.28
Step-by-step explanation:
As we have given that Sales prices of baseball cards have a right-skewed distribution with a mean $5.25 and a standard deviation is $2.80.
Now, We know that if standard deviation = σ
then, standard error =
As, we have standard deviation = $2.80
then standard error will be
⇒ Standard error = $0.28
Hence, Option (c) is the correct option.
The equation of the line that passes through points (-1, -10), and (3, 14) is y = 6x - 4.
<h3>What is a straight line?</h3>A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
We have two points shown in the table:
(-1, -10), and (3, 14)
y - 14 = 6(x - 3)
y = 6x - 4
Thus, the equation of the line that passes through points (-1, -10), and (3, 14) is y = 6x - 4.

Answer:
The total cost for each health club will be the same after 4 months.
Step-by-step explanation:
- Let A = membership fee for studio A
- B = membership fee for studio B
- x= membership month
We want to when the total cost at each health studio is the same.
In other words, when A = B.
Therefore, the expression becomes
Step 1: Simplify both sides of the equation.
Step 2: Subtract 18.25x from both sides.
Step 3: Subtract 22 from both sides.
Step 4: Divide both sides by 6.25
Therefore, the total cost for each health club will be the same after 4 months.
