Answer:

B. The probability of getting a red convertible is 0.10.

Step-by-step explanation:

Independent events:

Two events, A and B, are independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

P(A \cap B) = P(A) \times P(B)

In this question:

Event A: Red car -> 0.25 probability

Event B: Convertible car -> 0.4 probability

Independent if:

The probability of getting a red convertible car is:

P(A \cap B) = P(A) \times P(B) = 0.25*0.4 = 0.1

Thus, the correct answer is given by option B.

Find a equation for the following pattern! Help!!!
tester [92]

Answer:

y = \frac{1}{2} x

Step-by-step explanation:

The equation of a linear pattern has the form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (1, \frac{1}{2} ) and (x₂, y₂ ) = (2, 1) ← 2 ordered pairs from the table

m = \frac{1-\frac{1}{2} }{2-1} = \frac{1}{2} , thus

y = \frac{1}{2} x + c ← is the partial equation

To find c use any ordered pair from the table and substitute into the partial equation.

Using (2, 1) , then

1 = 1 + c ⇒ c = 1 - 1 = 0

y = \frac{1}{2} x + 0 ← equation for pattern or quite simply

y = \frac{1}{2} x

Write the equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8)
nataly862011 [7]

Answer:

y=\frac{x}{0.3}-18 \ or \ 3y=10x-54

is the equation of perpendicular line.

Step-by-step explanation:

We are given , the equation of a line is  y=-0.3x. +6

We can deduce that the slope of the given line is m=-0.3

The slope of its perpendicular line would be , m_p= \frac{-1}{m} =\frac{1}{0.3}

Now using the point slope form, y-y1= m_p(x-x1)

Use the given point (3,-8) \ as\ (x1,y1) substituing these.

y-(-8)= \frac{1}{0.3} (x-3)\\y+8=\frac{x}{0.3} -10\\y=\frac{x}{0.3} -18

Therefore the required equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8) is y=\frac{x}{0.3} -18[/tex]
