One jar holds 40 purple marbles and 5 black marbles. A second jar holds 90 orange marbles and 10 black marbles. What is the probability that a black marble will be drawn from both jars?

Step-by-step explanation:

The first jar holds 45 marbles and 5 of them are black.

The second jar holds 100 marbles and 10 of them are black.

Required probability:

Now we have to find,

The probability that a black marble will be drawn from both jars.

The given information is,

→ 1st jar contains/holds 45 marbles.

→ 5 of the marbles are black.

→ 2nd jar contains/holds 100 marbles.

→ 10 of the marbles are are black.

Then the probability will be,

→ P(b,b)

→ (5/45) × (10/100)

→ (1/9) × (1/10)

→ 1/90

Thus, required probability is 1/90.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
