Step-by-step explanation:
7^2+8^2=113
Then square root 113 which is 10.63 to 2.d.p
So x=10.63
The value that could me added to 2/5 that could make the sum greater than 1/2 is 1/5 possibly. Hope this helps! :)

Answer:
n=3.8416≅4
So Minimum Sample Size is 4
Step-by-step explanation:
In order to find the minimum sample size, the formula we use will be:
Where:
n is sample size
Z is the distribution
S is the standard deviation
E is the Margin of error
S=3 ,E=3
For Z:
Alpha=1-0.95=0.05
Alpha/2=0.025=2.5%
From Cumulative Standard Distribution Table:
Z at Alpha/2 = 1.960
n=3.8416≅4
So Minimum Sample Size is 4
Answer:
ratio 80:250
Step-by-step explanation:
there will be less people than babies
(1,9) (-3,5)
Midpoint = (1+{-3}/2) (9+5/2)
(1-3/2) (14/2)
(-2/2) (7)
(-1) (7)
Midpoint Answer = (-1, 7)
