A card is selected randomly from a jar that contains 15 cards, numbered from 25 to 39. What is the probability that the card sel
VikaD [51]

Answer:

The probability that the card selected bears a number less than 34 is 0.3333.

Step-by-step explanation:

Let random variable <em>X</em> be defined as the number on the selected card.

There are <em>N</em> = 15 total cards.

The number on the cards are as follows:

S = {25, 26, 27,..., 38, 39}

The probability of an event, <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.

P(E)=\frac{n(E)}{N}

In this case we need to compute the probability that the card selected bears a number less than 34.

The favorable outcomes are:

<em>s</em> = {25, 36, 37, 38, 39}

<em>n</em> (X < 34) = 5

Compute the probability that the card selected bears a number less than 34 as follows:

P(X

                  =\frac{5}{15}\\\\=\frac{1}{3}\\\\=0.3333

Thus, the probability that the card selected bears a number less than 34 is 0.3333.

Write an equation that passes through the points (0,-5) and (8,-5)
bezimeni [28]

Answer:

Equation of the line: y = -5.

Step-by-step explanation:

Let (x_0,\, y_0) and (x_1,\, y_1) denote the coordinates of these two points, respectively.

Calculate the slope m of this line:

\displaystyle m = \frac{y_1 - y_0}{x_1 - x_0} = \frac{(-5) - (-5)}{8 - 0} = 0.

Notice that the slope is zero because the two points have the same y-coordinates (y_0 = y_1 = -5) even though their x-coordinates are distinct (x_0 \ne x_1.)

Equation for this line in point-slope form:

y - y_0 = m\, (x - x_0).

y - (-5) = 0\, (x - 0).

Rewrite and simplify to obtain the equation of this line in slope-intercept form:

y = -5.

The x-term was eliminated because the slope was zero.

the point-slope form of the question of the line that passes through (-4,-3) and (12,1) is y-1=1/4(x-12). what is the standard f
Alexeev081 [22]
Well first off you multiply the parenthesis 1/4(x-12) you get -1=1/4x-3 then you subtract the one so now the y can be by itself the you get Y=1/4x-2
