Answer:
Margin of error = 0.01344
Step-by-step explanation:
Margin of error = critical value × standard deviation.
critical value for 95% confidence interval = 1.96
Standard deviation = √[(p)(q)/n]
p = 0.4, q = 1 - p = 1 - 0.4 = 0.6, n = 5100
Standard deviation = √[(0.6×0.4)/5100] = 0.00686
Margin of error = 1.96 × 0.00686 = 0.0134
Answer:
(g+f)(x)=(2^x+x-3)^(1/2)
Step-by-step explanation:
Given
f(x)= 2^(x/2)
And
g(x)= √(x-3)
We have to find (g+f)(x)
In order to find (g+f)(x), both the functions are added and simplified.
So,
(g+f)(x)= √(x-3)+2^(x/2)
The power x/2 can be written as a product of x*(1/2)
(g+f)(x)= √(x-3)+(2)^(1/2*x)
We also know that square root dissolves into power ½
(g+f)(x)=(x-3)^(1/2)+(2)^(1/2*x)
We can see that power ½ is common in both functions so taking it out
(g+f)(x)=(x-3+2^x)^(1/2)
Arranging the terms
(g+f)(x)=(2^x+x-3)^(1/2) ..

Alright 21 miles per hour. We know that there are 60 minutes in an hour. So this is basically saying 21 miles per 60 minutes. To find the rate for miles per minute, you divide 21 by 60 which is 0.35.
In one minute the cyclist rides 0.35 miles
In two minutes the cyclist rides 0.7 miles
What I like to do to solve these is to divide the 175 by 100 because that's kind of what it relates to a percent... and then I multiply by 96. So in this problem:
175/100= 1.75
1.75 x 94 and then that equals your answer 164.50 euros is the new cost of the ticket.
Hope this Helps!
P.S a thanks or brainliest would mean a lot. :)
