The mean family income for a random sample of 550 suburban households in Nettlesville shows that a 92 percent confidence interva

l is ($45,700, $59,150). Braxton is conducting a test of the null hypothesis H0: µ = 44,000 against the alternative hypothesis Ha: µ ≠ 44,000 at the α = 0.08 level of significance. Does Braxton have enough information to conduct a test of the null hypothesis against the alternative?
multiple-choice options:
H0: µ > 17 miles per gallon, Ha: µ ≥ 17 miles per gallon

H0: µ ≤ 17 miles per gallon, Ha: µ < 17 miles per gallon

H0: µ = 17 miles per gallon, Ha: µ > 17 miles per gallon

H0: µ = 17 miles per gallon, Ha: µ < 17 miles per gallon

H0: µ = 17 miles per gallon, Ha: µ ≠ 17 miles per gallon

Find the distance UV between the points U (7,-4) and V(-3,-6). Round your answers to the nearest tenth,if necessary
rodikova [14]

Answer:

<h3>The answer is 10.2 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

U (7,-4) and V(-3,-6)

The distance between them is

|UV|  =  \sqrt{( {7 + 3})^{2}  + ( { - 4 + 6})^{2} }  \\  =  \sqrt{ {10}^{2}  +  {2}^{2} }  \\  =  \sqrt{100 + 4}  \:  \\  =  \sqrt{104}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 2 \sqrt{26}  \:  \:  \:  \:  \:  \:  \:  \:   \\  = 10.1980...

We have the final answer as

<h3>10.2 units to the nearest tenth</h3>

Hope this helps you
