Answer:

The probability that it would contain at least 6 letters is: 5/8

Step-by-step explanation:

From the question given above,

We know that there are 8 planet that was given.

Mercury 7 letters

Venus 5 letters

Earth 5 letters

Mars 4 letters

Jupiter 7 letters

Saturn 6 letters

Uranus 6 letters

Neptune. 7 letters

Therefore,

P(at least 6 letters) + P( Less than 6 letters) = 1

P (at least 6 letters) + P (3 planet) = 1

P (at least 6 letters) + ( 3/8) = 1

P(at least 6 letters) = 1 - (3/8)

= 5/8

Use the given conditions to write an equation for the line in point-slope form. Passing through (2,-3) with x-intercept = -2

goldfiish [28.3K]

The equation for line is $y=-\frac{3}{4} x-\frac{3}{2}$

Explanation:

It is given that the line passes through the point $(2,-3)$ with x-intercept = -2

The x intercept is the value of x when y = 0.

Thus, it can be written in coordinate as $(-2,0)$

Now, we shall determine the slope using the points $(2,-3)$ and $(-2,0)$

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting, we get,

$m=\frac{0+3}{-2-2} \\m=-\frac{3}{4}$

Thus, the slope is $m=-\frac{3}{4}$

Now, we shall substitute the point $(2,-3)$ and slope $m=-\frac{3}{4}$ in the point-slope formula $y-y_1=m(x-x_1)$ , we get,

$y+3=-\frac{3}{4} (x-2)$

Multiplying both sides by 4, we get,

$4y+12=-3x+6$

Subtracting both sides by 12,

$4y=-3x-6$

Dividing both sides by 4, we get,

$y=-\frac{3}{4} x-\frac{3}{2}$

Thus, the equation of the line is $y=-\frac{3}{4} x-\frac{3}{2}$
