mr. diaz created the box plot below to
summarize the grades on a recent assignment.

which statement is a valid conclusion based on
box plot?

a. the lowest grade earned on the assignment
was 20%.
b. the mean for this data set is 65%.
c. 50% of the students earned a score 2 65%.
d. twice as many students earned a grade of
65-85% as those who earned a grade of 55-65%.

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
