Three balls are selected at random without replacement from an urn containing two white balls and four blue balls. Find the probability of the given event. All of the balls are blue.

Answers

Answer 1

Answer:

P(3 blue) = 1/5

Steps:

P(3 blue) = 2/3 × 3/5 × 1/2

P(3 blue) = 6/30

P(3 blue) = 1/5

that's 20%

a and b are positive integers and a - b = 2. Evaluate the following:
3b/3а

Answers

Answer and Step-by-step explanation:

a - b = 2

[tex]\frac{3b}{3a}[/tex] = [tex]\frac{b}{a}[/tex]

b = a - 2

a = b + 2

______________

b = b + 2 - 2

b = b

______________

______________

a = a - 2 + 2

a = a

______________

If a equals 0, then the expression is undefined.

If b = 0, then the expression is 0.

There are infinite number of solutions when a is not 0 and the numbers are positive.

Find the percent of change. Round to the nearest whole percent. Joe thought it would take him 74 minutes to complete the job. It actually took him 85 to complete the job.

Answers

Answer:

15%

Step-by-step explanation:

plug your numbers to the equation

(85-74)/74 then multiply that by 100

then move the decimal right 2 places

Answer:

15%

First of all, you need to find the difference between 85 min and 74 min.

85-74=11 min

Now, we need to find %increase-

increase/Original *100

11/74*100=

14.8648648649

= 14.8

15% if you were to round.

11. The ratio of men to women at a track meet is 4:5. If there are 20 men at the meet, use a proportion to determine how many people are at the meet.​

Answers

Answer:

There are 36 people at the meet

Step-by-step explanation:

if the ratio is 4 men to 5 women it means that every time there are 4 men there will be 5 women so its 4/5

and since we know there are 20 men the equation becomes:

4/5 = x/20

so to make 4/5 have 20 as a denominator we multiply by 4/4.

4/5*4/4 = 16/20

So, now we know there are 16 women.

And 16+20 = 36

Answers

9514 1404 393

Answer:

  17 2/3

Step-by-step explanation:

A calculator or spreadsheet can figure this. The maximum of f(x) is found where 3x-2 intersects 25-x.

  2x +3 = 25 -x

  3x = 22

  x = 22/3 = 7 1/3

  25 -7 1/3 = 17 2/3 . . . . maximum value of f(x)

_____

Note in the graph that the slope of f(x) decreases at about x=5. The expression with the lower positive slope is 2x+3. So, it is that expression that must equal the expression with the negative slope.

The rectangular prism has a volume of 936 cubic inches. Write and solve an equation to find the missing dimension of the prism.

Answers

Step-by-step explanation:

A rectangular prism is nothing but a cuboid. Let the length , width and height of the  rectangular prism be l, w and h.

We know that volume of a cuboid V = l×w×h

So,  l×w×h = 936

So, we can find any dimension of the prism provided the the other two dimensions are given to us.

Ted bought a fishing pole for $35.99, bait for $16.99, and a pair of shorts for $21.99. He had a coupon for 50% off the shorts only. What was the total cost of Ted’s items before tax?

Answers

Calculate the shorts price first
Since the short is 50% off, you can just divide the shirt cost by 2
21.99/2 = $10.99500 for shorts
Add all the items together now
35.99 + 16.99 + 10.99500
= 63.97500

Answers

180-(59+52)=69
Y=69
All angles in a triangle add to 180°
So 63+69=132
180-132=48
X=48°

Answer:

Step-by-step explanation:

So we know that a straight line adds up to 180 degrees.

This means that:

52+59+y = 180

y + 111 = 180

y = 69

We also know a triangle also adds up to 180 degrees.

This means that:

y+x+63 = 180

69+63+x = 180

x + 132 = 180

x = 48
