Using it's concept, it is found that the probability that the special ball is chosen is given by:
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of outcomes is given by the combination of k balls from the set of n balls, given by:
One ball is special, hence the probability the special ball is chosen is given by:

Answer:
3.7
Step-by-step explanation:
Answer:
y = - 4x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x + b ← is the partial equation
To find b substitute (- 2, 5) into the partial equation
5 = 8 + b ⇒ b = 5 - 8 = - 3
y = - 4x - 3 ← equation of line
Step-by-step explanation:
3x= (-8) -4
x=(-12)/3
x= -4
Answer:
-1/8
Step-by-step explanation:
When slopes are perpendicular that means it's completely opposite.
The opposite of 8 is 1/8
But 8 is positive that means we have to make the pereldicular slope negative
Therefore your answer is -1/8
