3 and a half cookies! that should be the answer!
Given:
Population proportion,

= 57% = 0.57
Population standard deviation, σ = 3.5% = 0.035
Sample size, n = 40
Confidence level = 95%
The standard error is

The confidence interval is

where

= sample proportion
z* = 1.96 at the 95% confidence lvvel
The sample proportion lies in the interval
(0.57-1.96*0.0783, 0.57+1.96*0.0783) = (0.4165, 0.7235)
Answer: Between 0.417 and 72.4), or between (41% and 72%)

Answer:
Reflection across y axis
Translate up by 3 units
Step-by-step explanation:
Given


Required
Describe the transformation from f(x) to g(x)
First, take a reflection of f(x) across the y axis.
So f(x) becomes f(-x)
when reflected

Next, translate f(-x) up by 3 units to give g(x)

Where




Hence, the transformation from f(x) to g(x) includes:
Reflection across y axis
Translate up by 3 units
Answer:
Step-by-step explanation:
60% = 7.2/12
83% = 10/12
He improved by a supposed 23%
