Answer:

Joelle:155,Anita:270

Step-by-step explanation:

Hello, I think i can help you with this.

Step 1

define

Let

A, Anita's score

J, Joelle’s score

According to the question data

  • their combined total score for one game was 425 points.in mathematics terms it is:

       A+J=425,equation (1)

  • Anita’s score was 40 less than twice Joelle’s: it means that you can take twice joelle's score  and subtract 40 to obtain Anita's scor

       2J-40=A,equation (2)

     ,

Step 2

find the values A and J

replace A from equation (2) into equation (1)

A+J=425

(2J-40)+J=425

solve for J

2J-40+J=425

3J=425+40

J=465/3

J=155

Now, put the value of J in equation (1) or equation (2) to find A

A+J=425

A+155=425

A=425-155

A=270

Hence, Joelle:155,Anita:270

Have a good day

75% of medicine this person took, you do that by doing 420/560 and you get .75. Then you move the decimal over twice since it asks for a percent and you get 75%

A) all first shift:
One is pulled 22/36
Second is pulled 21/35
Third is pulled 20/34
Fourth 19/33
Fifth 18/32
Sixth 17/31
Seventh 16/30
Eighth 15/29

Multiply all those together
Probability of all first shift is 0.010567296996663
(That means it's not happening anytime soon lol)

B) one worker 14/36
Second 13/35
Third 12/34
Fourth 11/33
Fifth 10/32
Sixth 9/31
Seventh 8/30
Eighth 7/29

Multiply all those together
Probability of all second shift is 0.000099238805645
(That means it's likely to see 100x more picks of all first shift workers before you see this once.. lol)

C) 22/36

X... p=0.016993464052288


Probably not correct, haven't done probability in years.
