Answer:
Step-by-step explanation:
The given inequality is y + 2 < 4x - 3
We have to rewrite the inequality to isolate y.
y + 2 < 4x - 3
(y + 2) - 2 < (4x - 3) - 2
y < 4x - 3
Now we will graph dotted line.
By plugging in the y = 4x - 3
we can get the different set of area representing right side of the dotted line will represent the inequality in the figure attached.

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.
