I hope you can understand what i wrote
Use formula y2-y1 over x2 - x1
3-0/4-0
3/4 is ur answer
The probability that student scored more than 850 we shall proceed as follows:
z=(x-μ)/σ
where:
x=850
μ=750
σ=50
thus
z=(850-750)/50
z=2
thus
P(x>850)=1-P(x<850)=1-P(z<2)=1-0.9772=0.0228
Answer: P(x>850)=0.0228
Answer:
Monique made 19 videos
Step-by-step explanation:
If Ana made 12 videos, but Monique made 7 videos more, you would use addition to find the answer.
12 + 7 = 19
Therefore, Monique made 19 videos and Ana made 12 videos.
I hope this helps :)
