Answer:

0.0792

Step-by-step explanation:

the probability that a family owns a dog= P(D)=36%=0.36

the probability that a family owns a dog also owns a cat=P(CnD)=22%=0.22

the probability that a family owns a cat =P(C)=30%=0.3

therefore, Probability that a randomly selected family owns both a dog and cat is given as

P(C∪D) = P(C∩D)×P(D)

=0.22×0.36

=0.0792

≈0.08

Answer:

$3.25 per gallon

Step-by-step explanation:

She had $30 and now has $4, so she spent $30- $4 = $26

With $24 she bought 8 gallons of gas.  

$26/(8 gallons) = $3.25/(1 gallon)      [ divide 26 by 8 to get the unit rate]

She spent $3.25 per gallon

What is the equation of the line that passes through the point (-3,-8) and has a slope of 4?
coldgirl [10]

Step-by-step explanation:

the easiest approach with a given point and the slope of the line is the point-slope form :

y - y1 = a(x - x1)

where "a" is the slope, and (x1, y1) is a point on the line.

so, we get

y - -8 = 4(x - -3)

y + 8 = 4(x + 3)

if we need the slope-intercept form

y = ax + b

we now simplify the point-slope form

y + 8 = 4x + 4×3 = 4x + 12

y = 4x + 4

Write the equation of the line with a slope of 1/6 that contains (12,-7)
tatiyna

\bf (\stackrel{x_1}{12}~,~\stackrel{y_1}{-7})~\hspace{10em} slope = m\implies \cfrac{1}{6} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-7)=\cfrac{1}{6}(x-12) \\\\\\ y+7=\cfrac{1}{6}x-2\implies y=\cfrac{1}{6}x-9
