which of the following gives an equation of a line that passes through the point (6 over 5, -19 over 5) and is parallel to the l
victus00 [196]
One equation for this would be

y = \frac{41}{16} x-\frac{55}{8}

We start by finding the slope between the two points:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{-12-\frac{-19}{5}}{-2-\frac{6}{5}}
\\
\\=(-12+\frac{19}{5}) \div (-2-\frac{6}{5})
\\
\\=(\frac{-60}{5}+\frac{19}{5}) \div (\frac{-10}{5}-\frac{6}{5})
\\
\\=\frac{-41}{5} \div \frac{-16}{5}=\frac{-41}{5} \times \frac{-5}{16}=\frac{41}{16}

A line parallel to this one will have the same slope.  We will use point-slope form to write our equation:

y-y_1=m(x-x_1)
\\
\\y-\frac{-19}{5}=\frac{41}{16}(x-\frac{6}{5})
\\
\\y+\frac{19}{5}=\frac{41}{16}x- \frac{41}{16} \times \frac{6}{5}
\\
\\y+\frac{19}{5}=\frac{41}{16}x-\frac{246}{80}
\\
\\y+\frac{304}{80}=\frac{41}{16}x-\frac{246}{80}
\\
\\y=\frac{41}{16}x-\frac{246}{80}-\frac{304}{80}
\\
\\y=\frac{41}{16}x-\frac{550}{80}
\\
\\y=\frac{41}{16}x-\frac{55}{8}

Which of the following are based on empirical probability
Vikentia [17]

The empirical probability is Life insurance, Car insurance, and Mortality.

<h3>What is empirical probability?</h3>

The ratio of the number of outcomes in which a defined event occurs to the total number of trials, not in a theoretical sample space but in a real experiment, is the empirical probability, relative frequency, or experimental probability of an event.

Therefore the empirical probability will be Life insurance, Car insurance, and Mortality.

3. Calvin has a bucket of marbles. The table shows the number of marbles of each color Color Amount Red Blue 3 Yellow 4 Green Ca
dalvyx [7]

The false statement is (c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

<h3>What are probabilities?</h3>

Probabilities are used to determine the chances of events

The table entry is given as:

  • Red  - 2
  • Blue - 3
  • Yellow  - 4
  • Green - 3

From the list of options, the false statement is

(c) the probability of selecting a blue or yellow marble is less than the probability of selecting a red or green marble.

This is so because:

  • Blue or Yellow = 3 + 4 = 7
  • Red or Green = 2 + 3 = 5

Notice the count of blue or yellow marbles (7) is greater than the number of  red or green marbles (5)

This means that, the probability of selecting a blue or yellow marble is greater than the probability of selecting a red or green marble.
