BU your vocabu A student surveyed 100 adults who took either vitamin C, zinc, or
echinacea supplements to prevent getting a cold. The adults were
asked if they had a cold or no cold in the last 30 days. The results
are shown in the table.

For each of the following questions, enter your answers as a
decimal. Round to the nearest hundredth for number 1. Round to
the nearest thousandth for numbers 2 and 3.
1. What proportion of adults in the survey took echinacea?
2. What proportion of adults who took vitamin C reported having
a cold in the last 30 days?
3. What proportion of adults who reported having a cold took
zinc?

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
