Answer:
0.350
Step-by-step explanation:
Confidence interval = point estimate ± margin of error
Point estimate = Confidence interval - margin of error
To get the margin of error, we will take the average of the difference of the interval given. Given the confidence interval 0.325<p<0.375
Margin of error = 0.375-0.325/2
Margin of error = 0.050/2
Margin of error = 0.025
Using the interval of 0.375
Point estimate = 0.375 - 0.025
Point estimate = 0.350
Fraction that Sam painted in 1 min is:
10/25=2/5
Fraction that you painted in 1 min:
5/25=1/5
Fraction pained by both in 1 min:
1/5+2/5=3/5 ft²/min
Time taken to paint 50 ft² will be:
time=3/5×50=30 min
Thus we conclude that Sam was wrong.
Answer:
The correct answer is: Option 3.
Step-by-step explanation:
To begin the problem asks to find 
· 
which can be defined as ](https://tex.z-dn.net/?f=%5Bf%2Ag%5D%28x%29)
. Now we are given that:
So now we need to 'multiply' our two algebraic expressions as follow:
Eqn.(1)
The domain of Eqn. (1) is all real numbers of 
.
Which according to the given options , Option 3 is correct.
