Answer:
hello your question has a missing table attached below is the missing table
Answer : 0.55%
Step-by-step explanation:
The complete table related to the answer given above is attached below
using a 0.10 level of significance the percentage of the variance in the Y-values that shows a linear relationship with the X-values = 0.55%
The values for X^2 , y^2 and x*y is determined an entered into a table ( attached below as well )
Answer:
15=3*5
30=5*6
90=5*3*5*2*3
So, HCF=15
Step-by-step explanation:
Hope it helps
Answer:
x=18, y=9
Step-by-step explanation:
The lines of y+3 and 12 look equal to each other. So do x-3 and 15. Because of this, we set each equal to each other and solve.
solving for x:
x-3 = 15
+ 3 +3
x=18
solving for y:
y+3=12
- 3 -3
y=9

80+60=140
Section A: 80/140= 57.14% of total grade
Section B: 60/140= 42.86% of total grade
57.14(.55) + 42.86(1) = greatest percentage= 74.287%
You would multiply Section B's part of the grade by 1 (100%) because to get the greatest percentage possible on the entire examination she would have to get 100% on the second part.
Answer:
Step-by-step explanation:
Let the number children tickets = c
Number of adult tickets = 75% of c = 0.75c
c + 0.75c = 1750
1.75c = 1750
c = 1750/1.75 = 1000
Number of children = 1000
Number of adults = 75% of 1000 = 750
Cost of adult ticket = $ x
Cost of child ticket = 75% of x = 0.75x
Cost of 750 adult ticket = 750x
Cost of 1000 children ticket = 1000 * 0.75x = 750x
750x + 750x = 27000
1500x = 27000
x = 27000/1500
x = $ 18
Cost of adult ticket = $ 18
Cost of children ticket = 75% of 18 = 0.75 * 18 = $ 13.5
Cost of children's ticket = $ 13.50
