Can someone please help me with the last three?? I don’t know what I keep doing wrong.

1. 78.22%

2. 0.342%

3. 21.77%

Step-by-step explanation:

To find the percentage, you multiply the fraction of those tested positive/negative (based on the question) out of the total by 100%.

1. × 100% = 78.22% (2 d.p.)

2. × 100% = 0.342% (3 d.p.)

3. × 100% = 21.77% (2 d.p.)

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
