A bag contains 5 red marbles, 8 white marbles, and 7 blue marbles. You draw 4 marbles out at random, without replacement. What is the probability that all the marbles are red?

Answers

Answer 1

Answer: 8/7752

Step-by-step explanation:

Since we are told that the bag contains 5 red marbles, 8 white marbles, and 7 blue marbles. The total number fo marbles would be:

= 5 + 8 + 7

= 20 marbles

If 4 marbles out at random, without replacement, the probability that all the marbles are red would be:

= 5/20 × 4/19 × 3/18 × 2/17

= 1/4 × 4/19 × 1/6 × 2/17

= 8/7752

The length of a rectangle is 5 less than 3 times the width. What is the length?

Perimeter = 46 inches
Write an inequality or equation, then solve.

Answers

Answer:

Let the width of the Rectangle be x inches

Then, length is (3x-5) inches

Perimeter of the Rectangle= 46 inches (given)

According to the above problem,

Equation :---- Perimeter=2(length+breadth)

2{(3x-5)+x}=46

2(4x-5)=46

(4x-5)=46/2=23

4x=(23+5)=28

x=28/4

x=7

So, length of the Rectangle is {(3×7)-5}=16 inches

and width is= 7 inches

Answer:

So, length of the Rectangle is {(3×7)-5}=16 inches

and width is= 7 inches

Step-by-step explanation:

Jefferson Elementary has a rectangular playground. A scale drawing of the playground is shown below.
10.5 cm
4.2 cm
The shortest side of the playground has an actual length of 33.6 meters.
What is the actual area, in square meters, of the playground?

Answers

I'm sorry if I get this wrong, but there isn't enough evidence.

If we think about the shorter side being 4.2 cm, then just divide 33.6 by 4.2 to give it a ratio. 33.6 / 4.2 is 8. The ratio of the scale drawing to the actual playground would be 1 : 8.

The longer side is 10.5, so just multiply that by 8. You'd get 84 meters. The only part left is getting the area.

Multiply 84 x 33.6 and you'd get 2822.4

The answer would be 2,822.4 squared.

Absolute value is basically:


A. A number's distance from 0 on a number line


B. The greatest number on a number line

Answers

Answer:

A because absolute value doesn't change the actual value of the number, just makes it positive no matter what, but it's still the same distance from 0, just in the opposite direction.

Step-by-step explanation:

Answer:

A : a number distance form 0n the number line

Step-by-step explanation:

ex: if you want to find the absolute value of -4 you would look at the distance from zero so it would be 4 from zero so the absolute of -4 is 4

You walk 2 miles from your house to the park and 4.5 miles from the park to the lake. Then you return home along a straight path from the lake. How many miles do you walk from the lake back to your house? What is the total distance you walk?

Answers

Answer:

Lake to House= ~4.92.  Total Length= 11.42 miles

Step-by-step explanation: Lets assume that it is a right triangle .

Your house being the 90 degree angle and the path from the lake to your house being the hypotenuse.

Then to find the lenght you did Pythagorean theorem:

a^2 + b^2 = c^2

a=2mi

b=4.5

(2 * 2) + (4.5 * 4.5) = c^2

24.25= c^2

[tex]\sqrt{24.25}[/tex] = [tex]\sqrt{c^{2} }[/tex]

c = ~4.92

Mark has 10 pens. Kate has 5 times as many pens as Mark. Which equation below answers how many pens Kate has?

Answers

Answer:

5m = k or 5(10) = k

Step-by-step explanation:

Let m represent Mark

Let k represent Kate

So, it is 5 times the amount that Mark has, so that is 5m = k

or just simply 5(10) = k

The pens that Kate has is equal to 50

What is an equation in math?

In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given here, let  mark has x= 10  pens and Kate has 5 times as many pens as Mark then kate would have 5x pens

therefore5x = 5×10

                    = 50 pens

Hence,  The pens that Kate has is equal to 50
