a bout crew rowed 16kilometers downstream, with the current, in 2 hours. the return teip upstream, against the current, covered
gtnhenbr [62]

Solving for both velocities:

16 km / 2 hours = 8 km per hour downstream

16 km / 4 hours = 4 km per hour upsteram

bsw means boat speed in still water  cs means current speed

bsw - cs = 4 km per hour

bsw + cs = 8 km per hour

Adding both equaions:

2 bsw = 12 km per hour

boat speed = 6 km per hour

bsw + cs = 8  then

current speed = 2 km per hour

Find the quotient. simplify your answer s-4/s / 8/s
lapo4ka [179]

Your input: find the difference quotient for f(s)=s−12s2.

A difference quotient is given by f(s+h)−f(s)h

To find f(s+h), plug s+h instead of s:

f(s+h)=s−12s2

Finally, f(s+h)−f(s)h=(s−12s2)−(s−12s2)h=0

Answer: the difference quotient for f(s)=s−12s2 is 0.

Determine the point estimate of the population mean for the confidence interval of (15, 32). Enter up to 1 decimal place. Point
netineya [11]

Answer:

The point estimate of the population mean for the confidence interval of (15,32) is 23.5

Step-by-step explanation:

We are given the following information in the question:

Confidence interval for population mean is (15, 32).

We have to find the point estimate for population mean.

Formula:

\mu = \displaystyle\frac{\mu_1+\mu_2}{2} = \frac{15+32}{2} = 23.5

The point estimate of the population mean for the confidence interval of (15, 32) is 23.5
