In a random sample of 85 people attending a workshop, 63 of the respondents said the workshop was useful. What is the sample proportion of
the people who said the workshop was useful?
OA 0.13
B. 0.48
C.
0.63
D.
0.74

the answer is D

Step-by-step explanation:

because 63÷85 is 0.74

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
