Answer:
2:1
Step-by-step explanation:
J:P = 5:8
30:48
48-30= 18
48-22= 26
30+22= 52
new ratio
52:26
2:1
0.1 is the greater number
If you start at 0 and the next number is .75 then you must add .75 to each new number
therfore 2.25 + .75= 3.00
3.00+.75= 3.75
0,0.75,1.5,2.25,3.00,3.75

Answer: 0.81859
Step-by-step explanation:
Using the formula ;
Z = 
where u = mean
Therefore the probability that a student will finish the test between 40 and 70 will be :
P ( 40≤X≤70 ) = P(X≤70) - P(X≤40)
P ( 60-40/10) , P( 60 - 70 / 10)
= 2 , -1
= P (Z ≤ 2) - P( Z ≤ -1 )
From normal table , we have
0.97725 - 0.15866
Therefore the probability that a student will finish the test between 40 and 70 minutes = 0.81859
