Um the picture isn´t very clear it is hard to see it.
Step-by-step explanation:
at least on my end it is.
To find how long it would take him, one has to divide 400 by 160 and then multiply 5 by what that number is. You multiply 5 by the quotient because that is the number that would make it proportional. 400/160 x 5 is 12.5, meaning that the answer is 12.5 minutes, or A.
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.

We need the perimeter of the window for framing
The window is in the shape of a rectangle with the height of
feet and width of
. The diagram of the shape is shown below
The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.
The perimeter of the window is
=
We have two whole numbers 18 and 12 and two fractions
and
Adding the two fractions that have different denominator
, which is an improper fraction which we can change into a mixed number
So the perimeter of the window is
and the length of wood needed for the frame is
feet
