Answer:
point of estimate p = x/n
Step-by-step explanation:
p is the point estimate for the population , x is the number of success, n is the sample size.
p = Upper bound + Lower bond/ 2 for population proportion
x = Upper bond + Lower bond /2 for population mean
E = Upper bond - Lower bond /2 E is margin of error
First, we can expand the terms on the right side of the equation:
y
−
10
=
2
(
x
−
8
)
y
−

=
(

x
)
−
(

)
y
−

=

x
−
16
Next, we can add
10
and subtract
2
x
from each side of the equation:
−
2
x
+
y
−

5x3=15 3x2=6 15x6=90 So your answer is 90.
Answer:
100
Step-by-step explanation:
10,000 is merely 100 x 100 = 100²
so √10,000 = √100² = 100
