X=number looked for
we have this equation:
-52(x-14)=x+3
we solve this equation:
-52x+728=x+3
-52x-x=3-728
-53x=-725
x=-725/-53=725/53 ≈13,68
Solution: 725/53
To check:
the difference between 725/53 and 14=725/53 - 14=(725-742)/53=-17/53
-52 times the diference is= -52(-17/53)=884/53
The number plus 3=725/53 + 3=(725+159)/53=884/53
1. X=3, 2. X=4, 3. X= 95/2
Answer: True
Step-by-step explanation:
Sensitivity in such a scenario is used to measure the accuracy of the screening method. In other words, how effective is the screening method at detecting Colon Cancer.
The sensitivity of the method can be calculated by dividing the amount of people that it showed as positive by the number of people that were actually tested.
The number of people who showed positive were 14 and the amount of people tested were 16.
Sensitivity therefore is,
= 14/16
= <u>0.875</u>
<em>They should indeed determine the sensitivity of the newly proposed screening method to be .875.</em>

Step-by-step explanation:
Children are playing a number game by drawing number cards.
1. First card was drawn 2, used as start point.
It was plotted on the number line.
2. Second card was drawn and it was -6.
Operation performed, starting from point 2 moved 6 points to the left:
3. The next card drawn had number 2 on it.
Operation performed, starting from point -4 moved 2 positions to the right.
End point -2
