Answer:
Limits for B scores
( 79,2 ; 92 )
Step-by-step explanation:
The interval we are looking for is between 6 % and 59%
p₁ = 6 % p₁ = 0,06
As this point is at the right tail of the bell we better look for
p = 1- 0,06 p = 0,94
In z-table z score for 0,94062 is: z₁ = 1,56 ( 0,94062 ≈ 0,94 )
Doing the same to find z₂ score for 59% or 0,59
In z-table again
p = 0,59
z₂ = 0,023
Now we know
1,56 * σ = x₁ - 79
1,56*8,4 + 79 = x₁
x₁ = 92,10 or x₁ = 92
And
0,023*8,4 + 79 = x₂
x₂ = 79,19 or x₂ = 79,2
Answer:
Slope is 4/5
Step-by-step explanation:
The two points are (3,3) and (-2,-1)
The slope formula is Y2-y1 / x2-x1
So substituting in
-1-3/ -2 -3
-4/-5 = 4/5
You can check it by "walking" up 5 and over to the right 4 on the graph and see that it works.

Answer:
48%
Step-by-step explanation:
100/25= 4
so
12×4/ 25×4 = 48/ 100 = 0.48
0.48 ×100 = 48%
