Ax^2+bx+c
if a=1, then
take 1/2 of b and square it

w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2

I need help with #7 c and d
Misha Larkins [42]

Answer:

  c. 33.0%

  d. 14.5%

Step-by-step explanation:

For answering questions about percentages in different categories or combinations of categories, it is convenient to find the totals of rows and columns in the table. These totals are shown in the attached.

__

<h3>c.</h3>

Students who surf total 32+65 = 97. Of those, 32 also skateboard. The requested percentage is ...

  32/97 × 100% ≈ 33.0% . . . . surfers who also skateboard

__

<h3>d.</h3>

The total number of students is 166. Of those, the number who neither surf nor skateboard is 24. That percentage is ...

  24/166 × 100% ≈ 14.5% . . . . students who don't surf or skateboard

_____

<em>Additional comment</em>

a. 97/166 ≈ 58.4% surf

b. 89/166 ≈ 53.6% do not skateboard

__

This sort of table is called a "two-way table." One set of categories is represented in rows, another set is represented in columns. This table is filled with <em>frequencies</em>. Such tables can also display <em>relative frequencies</em> by dividing the entire table by the total of totals in the lower right corner.

Approximately how many liters are in 20 gallons 1 L 0.26 gal.
Sergeu [11.5K]

Answer:

77 litres

Step-by-step explanation:

1L = 0.26 gal

0.26 gal = 1L

Divide both sides by 0.26

1 gal = 1 ➗ 0.26

1 gal = 3.85 L

Now multiply both sides by 20

20 gal = 3.85 × 20

20 gallons = 77 litres
