Step-by-step explanation:
No. of points got from 1 stunt = 50.
No. of points deducted from 1 fail = 40.
6 stunts and 9 falls were gained last week.
So, A/C the number of points earned =
(6×50)-(9×40)
= 300 - 360
= -60
Her score today is 3 times her score from last week so multiply by 3
= (-60) × 3
= -180
If it were multiplied by -3 instead of 3 it would be...
(-60) × (-3)
= 180
The difference would be that on multiplying with positive 3 she would be 180 points in the whole but multiplying with negative three means she is 180 points in the league.
The similarity is that that whole number is same but the symbol adds a difference and the absolute value would be same too.
I can't see the picture, can you add it again so I can help?
Experimental is the actual measured desiredoutcome/totaltrials
total trials=10+12+28=50
green is 28
so 28/50 or 14/25 is the experimental proablity of doing green
theoretical is desired/total possible,
total possible=total number of marbles=5+8+12=25
desired=8, so 8/25 is theoretical probablity of draing green
I would expect the experimental proabblity to approach the value of the theoretical proabblity, not sure why tho
Answer:
Step-by-step explanation:
Each question has 4 options with only one correct answer and all other incorrect answers. Student is equally likely to pick any outcome in any given question. Hence, probability of choosing correct answer is 1/4 = 0.25
mark this as brainly pls.....
