Answer:
9.) I 5/14 * 4/13 10.) H 45
Step-by-step explanation:
For 9.) the probability the first time to get a red marble is 5/14 because there are 5 red marbles and 14 total marbles. The probability the second time she picks, if a green one was chosen, one is 4/13 because one green marble needs to be missing and because one marble is missing 14-1=13 so there are 13 total marbles. You would multiply the two probability (5/14 and 4/13) to find the probability of drawing two green marbles in a row
For 10.) I found that 2/5= .4 and 5/8= .625 so I multiplied both fractions by 200
.4 * 200= 80
.625 * 200= 125
These are the numbers of games both people won
Subtract the two and you get 125-80= 45 which is how many more games Tyrell would win.
Answer:
d)13sin75/sin55
Step-by-step explanation:
1)Given
inΔVWU, ∠V= 75°
∠U= 50°
Finding ∠W:
∠W= 180-(75+50)
=180-(125)
= 55
Now finding x, using law of sine
x/sinV = 13/sinW
Putting the values in above we get:
x/sin75=13/sin55
Re-arranging, we get:
x= 13sin75/sin55 !
Answer:
For interquartile range, you will need to find the range of the boxes, and not the line since for the lower quartile is 5.5 and the higher qaurtile is 7, the interquatile range is 1.5
