A) 20 households are randomly selected from the town; 8 own a dog

why: when conducting a survey to determine approximations in a population, it’s best to eliminate any and all biases for best results. Households who live near a park or have their own front yards will skew results as the rest of the population may not have access to those things, thus are more likely to not have a dog.

b) 8/20= 0.40
600*0.40= 240

In the figure below, points D, E, and F are the midpoints of the sides of LABC,

attashe74 [19]

Answers:

DE = 39
AB = 68
BE = 34

=============================================================

Explanation:

BC = 78 is parallel to the midsegment DE.

This parallel midsegment is half as long as BC, so DE = BC/2 = 78/2 = 39

-------

DF = 34 doubles to AB = 2*DF = 2*34 = 68, since the midsegment is half as the parallel side, so we just think in reverse of that process.

-------

BE = 34 for two reasons

Quadrilateral EBFD is a parallelogram with opposite sides BE and DF that are congruent.
E is the midpoint of AB, so BE is half as long as AB

--------

We don't use the info that AC = 48.

Can someone help me solve this and explain step by step algebraically <br> 1/8x+1/4y=2

mote1985 [20]

Answer:

$x=16-2y$

Step-by-step explanation:

$\mathrm{Subtract\:}\frac{1}{4}y\mathrm{\:from\:both\:sides}$

$\frac{1}{8}x+\frac{1}{4}y-\frac{1}{4}y=2-\frac{1}{4}y$

$\mathrm{Simplify}$

$\frac{1}{8}x=2-\frac{1}{4}y$

$\mathrm{Multiply\:both\:sides\:by\:}8$

$8\cdot \frac{1}{8}x=8\cdot \:2-8\cdot \frac{1}{4}y$

$\mathrm{Simplify}$

$x=16-2y$

Final Answer: $x=16-2y$
