Answer: 90% confidence interval is; ( - 0.0516, 0.3752 )
Step-by-step explanation:
Given the data in the question;
n1 = 72, n2 = 17
P1 = 54 / 72 = 0.75
P2 = 10 / 17 = 0.5882
so
P_good = 0.75
P_bad = 0.5882
standard ERRROR will be;
SE = √[(0.75×(1-0.75)/72) + (0.5882×(1-0.5882)/17)]
SE = √( 0.002604 + 0.01424)
SE = 0.12978
given confidence interval = 90%
significance level a = (1 - 90/100) = 0.1, |Z( 0.1/2=0.05)| = 1.645 { from standard normal table}
so
93% CI is;
(0.75 - 0.5882) - 1.645×0.12978 <P_good - P_bad< (0.75 - 0.5882) + 1.645×0.12978
⇒0.1618 - 0.2134 <P_good - P_bad< 0.1618 + 0.2134
⇒ - 0.0516 <P_good - P_bad< 0.3752
Therefore 90% confidence interval is; ( - 0.0516, 0.3752 )
Angle E, since it is a right triangle the other two have to be acute.
Pam would read 235 pages in 141 minutes or 2hrs and 21min.
Divide 3 from 5 to get the time it takes her to read 1 page which is 0.6 . Now multiply .6 by the number of total pages (235) to find the time it takes, which would be 141 minutes, 2.35 hours, or 2 hours and 21 minutes (whichever you prefer) ( 3/5 = .6 × 235 = 141 )
Answer:
Step-by-step explanation:
Use the Product Rule for derivatives, which states that:
In the function we are given, 
, we can break it up into two factors: -x is being multiplied by cos3x.
Now, we have the factors:
Before using the product rule, let's find the derivative of cos3x using the chain rule and the power rule.
Now let's apply the product rule to f(x) = -xcos3x.
Simplify this equation.
Multiply x and 3 together and remove the parentheses.
Therefore, this is the derivative of the function 
.
