3+ 4 + 5 = 12

So the chance of picking a marble that is not black is minus it

3+5 = 8 marbles are not black

Take 8 divided to the whole number which is 12

8/12= 66%

Hope this helps!

$|\Omega|=3+4+5=12\\|A|=3+5=8\\\\P(A)=\dfrac{8}{12}=\dfrac{2}{3}\approx66.7\%$

Answer:

Step-by-step explanation:

Let's write out what we know:

Noon temp: 54

Over the day, the temperature:

increased 8, decreased 3, increased 14, decreased 2, and decreased 10.

54+8-3+14-2-10 = 61

Bro i need this <br><br> (x − 5)^2 = x^2 − 25

forsale [732]

Answer:

x=5

Step-by-step explanation:

x^2+25-10x = x^2-25

-x^2 -x^2

25-10x = -25

-25 -25

-10x = -50

x=5

lets check

(5-5)^2 = 5^2-25

0^2 = 25-25

0 = 0

Find an equation of the line described below. Write the equation in slope-intercept form (solved for y), when possible.

SCORPION-xisa [38]

The equation of the line in slope-intercept form would be y = m(x - 1/5) - 8.

<h3>What is slope intercept form a straight line?</h3>

The slope-intercept form of a straight line is used to get the equation of a line. We need to know the slope of the line and the intercept where the line crosses the y-axis in order to use the slope-intercept formula.

One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope-intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.

Since the slope is undefined in the given question, let us consider it as m.

Therefore, slope=m

Given points are 1/5 and -8, so x₁ = 1/5 and y₁ = -8

We know the formula is, y - y₁ = slope × (x - x₁)

Putting the values of x₁, y₁ and slope in the given formula we get,

y -(-8) = m × (x-1/5)

y = m(x-1/5) - 8

Hence, we get the required equation.
