Find the midpoint of the segment from point a (6,3) to point B (8,1)
velikii [3]

Answer: M=(7,2)

Step-by-step explanation:

You need to use the following formula:

 M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})

Given the points A(6,3) and B(8,1), you can identify that:

x_A=6\\x_B=8\\y_A=3\\y_B=1

Now, you can substitute these values into the formula M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2}).

Therefore, you get this result:

M=(\frac{6+8}{2},\frac{3+1}{2})

M=(7,2)

ken wants to rent a car for a week and to pay to more than $130. how far can he drive if the car rental cost $94 a week plus $0.
cupoosta [38]
If Ken wants to pay more than 130, he needs to drive more than 90 miles. You subtract 94 from 130, which equals 36. 36 divided by .4 (for the price per mile) and it equals 90.

In a sample of 679 new websites registered on the Internet, 42 were anonymous (i.e., they shielded their name and contact inform
Semmy [17]

Answer:

95% Confidence interval:  (0.0429,0.0791)      

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 679

Number of anonymous websites, x = 42

\hat{p} = \dfrac{x}{n} = \dfrac{42}{679} = 0.0618

95% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96

Putting the values, we get:

0.0618\pm 1.96(\sqrt{\dfrac{0.0618(1-0.0618)}{679}}) = 0.0618\pm 0.0181\\\\=(0.0429,0.0791)

is the required confidence interval for proportion of all new websites that were anonymous.
