A box contains cards number 1-10. A card is drawn at random, without replacement, and a second card is drawn. What is the probability that the first number is a multiple of five and the second number is a multiple of three?

Answers

Answer 1

Answer:

Step-by-step explanation:

Total outcome is 10 and favorable outcome is 2 ⇒ the probability that the first number is a multiple of five is [tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex]

Total outcome is 9 and favorable outcome is 3 ⇒ the probability that the first number is a multiple of three is [tex]\frac{1}{3}[/tex] if first draw was successful, and [tex]\frac{2}{9}[/tex] if the first number was multiple of three.

Answer 2

Using conditional probability, it is found that there is a 0.0667 = 6.67% probability that the first number is a multiple of five and the second number is a multiple of three.

A probability is the number of desired outcomes divided by the number of total outcomes.

Conditional Probability

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.

In this problem:

Event A: First number is a multiple of 5.Event B: The second number is a multiple of 3.

There are 10 numbers, of which 2(5 and 10) are multiples of 5, hence [tex]P(A) = \frac{2}{10} = 0.2[/tex]

Then, supposing a multiple of 5 is taken, there will be 9 numbers, of which 3(3, 6 and 9) are multiples of 3, hence [tex]P(B|A) = \frac{3}{9} = \frac{1}{3} = 0.3333[/tex]

Then:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(A)P(B|A)[/tex]

[tex]P(A \cap B) = 0.2(0.3333)[/tex]

[tex]P(A \cap B) = 0.0667[/tex]

0.0667 = 6.67% probability that the first number is a multiple of five and the second number is a multiple of three.

Answers

Answer:

y + 2.3 = 0.45x

y = 0.45x - 2.3

-2y = 4.2x - 7.8

-2(0.45x - 2.3) = 4.2x - 7.8

-0.90x + 4.6 = 4.2x - 7.8

-0.90x - 4.2x = -7.8 - 4.6

-5.1x = - 12.4

x = -12.4 / -5.1

x = 2.4

y + 2.3 = 0.45x

y = 0.45(2.4) - 2.3

y = 1.08 - 2.3

You have 100 feet of fencing and decide to make a rectangular garden. What is the largest area enclosed

Answers

Answer:

625 ft^2

Step-by-step explanation:

Given

[tex]P = 100[/tex] --- perimeter

Required

The largest area

The perimeter is calculated as:

[tex]P = 2 * ( L + W)[/tex]

So, we have:

[tex]2 * ( L + W) = 100[/tex]

Divide both sides by 2

[tex]L + W = 50[/tex]

Make  L the subject

[tex]L = 50 - W[/tex]

The area is calculated as:

[tex]A= L * W[/tex]

Substitute [tex]L = 50 - W[/tex]

[tex]A= (50 - W) * W[/tex]

Open bracket

[tex]A = 50W - W^2[/tex]

Differentiate with respect to W

[tex]A' = 50 -2W[/tex]

Set to 0; to get the maximum value of W

[tex]50 - 2W = 0[/tex]

Collect like terms

[tex]-2W = -50[/tex]

Divide by -2

[tex]W = 25[/tex]

So, the maximum area is:

[tex]A = 50W - W^2[/tex]

[tex]A = 50 * 25 - 25^2[/tex]

[tex]A = 1250 - 625[/tex]

[tex]A = 625[/tex]

Answers

Answer:

V = pi r^2 h  where r is the radius and h is the height

We are given the diameter of 10

The radius is 1/2 of the diameter of 1/2 (10) = 5

V = (3) * (5)^2 * 11

V = 3( 25)*11

Answers

Answer:

3.2 liters

Step-by-step explanation:

The first thing we want to do is find the amount of water it leaks hourly

To do so we divide the amount of water it leaks in 3 hours ( .48 ) by 3

.48/3 = .16

So the faucet leaks .16 liters per hour

Now to find how much water the faucet leaks in 20 hours

To do this we simply multiply 20 by the hourly leakage amount (.16)

.16 * 20 = 3.2

So in 20 hours the faucet would have leaked 3.2 liters of water

Answer:

3.2 liters of water :)!

Step-by-step explanation:

If 0.48 every 3 hours we can do 0.48/3 to find the amount it loses every hour.

0.48/3=0.16

Then if we multiply 0.16 by 20 we will get the amount it loses in 20.

0.16x20=3.2

Hence, it loses 3.2 liters of water every 20 hours.

9. what is the measure of QSR

Answers

Answer:  C) 142 degrees

=======================================================

Explanation:

Extend segment MN such that it intersects side ST. Mark the intersection as point A. See the diagram below.

We're given that angle MNT is 72 degrees. The angle TNA is equal to 180-(angle MNT) = 180 - 72 = 108 degrees, since angles MNT and TNA add to 180.

For now, focus entirely on triangle TNA. We see from the diagram that T = 34 and we just found that N = 108. Let's find angle A

A+N+T = 180

A+108+34 = 180

A+142 = 180

A = 180-142

A = 38

So angle NAT is 38 degrees.

----------------------------

Since segment MA is an extension of MN, and because MN || SQ, this means MA is also parallel to SQ.

We found at the conclusion of the last section that angle NAT was 38 degrees. Angles QST and NAT are corresponding angles. They are congruent since MA || SQ. This makes angle QST to also be 38 degrees

----------------------------

The angles QSR and QST are a linear pair, so they are supplementary

(angle QSR) + (angle QST) = 180

angle QSR = 180 - (angle QST)

angle QSR = 180 - 38

angle QSR = 142 degrees

So, the missing values in the equation of proportion are 15, 40, 32 respectively.

[tex]\dfrac{x}{15}=\dfrac{4}{5}[/tex]

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are Given a quadratic function and its key features

To Determine: what key features its opposite function will have

The opposite function or inverse functions are reflections of each other over the straight line y = x.

We will find the inverse by switching x and y in the equation as;

f(x) = x² + 5

The inverse would be

x = √f(x) - 5

Once graph those two functions, that will see that they're symetrical that has y=x line by its middle line.

{(2,1), (4,2) (6,3) (8,4)} is what type of relation?

c. many-to-one
d. one-to-one

Answers

The given relation {(2,1), (4,2) (6,3) (8,4)} is one to many relation.

The other solution for this problem is given below.

The pattern is the sum of the two numbers plus the previous sum, i.e.

12 = 2+5 +(5)

21 = 3+6+ (12)

40 = 8+11 +21

These type of questions are part of reasoning and comes in random competitive exams which have multiple choice questions and therefore you have more than you want.

First , you need to multiply both numbers and then add the first number.

Therefore, 1+4= 1x4+1=5

2+5=2×5+2=12

3+6=3×6+3=21

What is the many to one relation?

A many-to-one relationship is where one entity (typically a column or set of columns) contains values that refer to another entity (a column or set of columns) that has unique values.

Hence,8+11=8×11+8=96

The other solution for this problem is given below.

The Solution for this is

1+4=5

1(4+1)=1(5)=5

2+5=12

2(5+1)=2(6)=12

3+6=21

3(6+1)=3(7)=21

Therefore we get,

8+11=8(11+1)=8(12)=96.

Therefore the given relation is any one to many relation.

What is the congruent triangle?

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.

Given that:

Line AD ⊥ar  bisector of BC.

BD=DC= 6 units

AC= 9 units

In △ABD and △ACD, we have

DB=DC (Given)

∠ADB=∠ADC  

(AD⊥BC)AD=AD (Common)

∴ by the SAS criterion of congruence, we have.
