Answer:
Son of 15 years $180
Son of 10 years $120
Step-by-step explanation:
15 + 10 = 25
25 300
15 x = 300*15/25
x = 180
25 300
10 x = 300*10/25
x = 120
Son of 15 years $180
Son of 10 years $120
Ansley should invite a minimum of 15 guests.
$500 - $130 = $470 / 25 = 14.8 but she needs to be over the amount so
15 guests is the answer
I hope this helps :)
Answer:
With alpha 0.95 and 8 degrees of freedom χ²= 2.73
And with alpha 0.05 and 8 degrees of freedom χ²=15.51
Step-by-step explanation:
The significance level ∝ = 1- 0.9 = 0.1
But we need the area of the middle so we divide this significance level with 2
so that we get exactly the middle area .
Dividing 0.1/2= 0.05
So we will have two values for chi square
One with 0.9 + 0.05 = 0.95 alpha and one with 0.05 alpha . This is because the chi square is right tailed.
So with alpha 0.95 and 8 degrees of freedom χ²= 2.73
And with alpha 0.05 and 8 degrees of freedom χ²=15.51
This can be shown with a graph.
