One jar holds 20 green marbles and 4 white marbles. A second jar holds 60 black marbles and 20 white marbles. What is the probab

Black_prince [1.1K]

Answer:

Step-by-step explanation:

Let RBY = “Draw a Red, then Blue, then Yellow”

● So all disjoint events we want to consider are: RBY,

RYB, YRB, YBR, BYR, BRY – there are 6 of them.

● P(RBY) = P(R)*P(B)*P(Y) = (30/55)*(5/55)*(12/55)

= .0108

● But we have 6 disjoint cases. Because each one is

calculated as a product of the three, and each

disjoint case has the same probability (each order is

equally likely), our answer is 6*.0108 = .0649

all expression represent how much Judith spent.

Answer:

Question:

Judith's grandmother paid her x dollars a week to mow the lawn during the summer. Judith decided to save some of her money and spend the rest. For the first 4 weeks, Judith put $10 per week into savings. For the next 8 weeks, she put $15 per week into savings.

Solution given:

Judith's grandmother paid her x dollars a week

it means Judith's income per week is x.

Judith decided to save some of her money and spend the rest.

For the first 4 weeks, Judith put $10 per week into savings.

it mathematical expression it is expressed as:

4(x-$10)

again

For the next 8 weeks, she put $15 per week into savings.

it mathematical expression it is expressed as:

8(x-$15)

now,

Judith's have

4(x-$10)+8(x-$15) it represent 1st expression.

solving above equation

(4x-$40)+(8x-$120) represents 4t h expression.

(4x+8x)-($40+$120) represents 2nd expression.

12x-$160 represents 3rd expression.

What are the four properties of parallelograms?

zepelin [54]

There are six important properties of parallelograms to know:

Opposite sides are congruent (AB = DC).Opposite angels are congruent (D = B).Consecutive angles are supplementary (A + D = 180°).If one angle is right, then all angles are right.The diagonals of a parallelogram bisect each other.Each diagonal of a parallelogram separates it into two congruent triangles.
