Answer 1

Answer:

The original number is 82

Step-by-step explanation:

Very interesting question!

There is only 1 number that satisfies this condition between 10 and 9999 (I could have gone much further but didn't)

That number is 82

If you subtract 7 from 82 you get 75

75/5 = 15

If you subtract 5 from 82 you get 77

77 divide by 7 = 11

Here's the kicker.

11 is 4 less than 15.

Isn't that a weird coincidence? No other number (I would bet) does that.

Fine FG , given that line HF is perpendicular bisector or EG

Answers

Answer:

FG = 7

Step-by-step explanation:

We'll begin by calculating HF. This can be obtained by using the pythagoras theory as illustrated below:

EF = 7

EH = 3

HF =?

EF² = EH² + HF²

7² = 3² + HF²

49 = 9 + HF²

Collect like terms

49 – 9 = HF²

40 = HF²

Take the square root of both side

HF = √40

Finally, we shall determine FG. This can be obtained as follow:

GH = 3

HF = √40

FG =.?

FG² = GH² + HF²

FG² = 3² + (√40)²

FG² = 9 + 40

FG² = 49

Take the square root of both side

FG = √49

FG = 7

Jack can build 1/5 of a shed in the same time Kyle build 5/8 of a shed. How much of a shed will jack have built when Kyle has finished building 1 shed.

Answers

Answer:

Step-by-step explanation:

If Kyle can get 5/8 of a shed built in x amount of time, he can get 62.5% done; if Jack can get 1/5 of the shed built in the same time, he can 20% of it done. As a ratio:

[tex]\frac{Kyle}{Jack}:\frac{62.5}{20}[/tex]  Kyle gets the whole thing done, 100% of the way, leaving Jack lagging behind at a somewhat lower percentage of the work being done.

[tex]\frac{Kyle}{Jack}:\frac{62.5}{20}=\frac{100}{x}[/tex] and cross multiply to solve for the percentage of the shed built by Jack by the time Kyle gets it completed:

62.5x = 2000 so

x = 32%

When Kyle will complete the work the amount of the work done by Jack will be 32%.

What is an expression?

Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

If Kyle can get 5/8 of a shed built in x amount of time, he can get 62.5% done; if Jack can get 1/5 of the shed built in the same time, he can 20% of it done. As a ratio:

Jack falls behind Kyle, completing only a small portion of the work, while Kyle completes the entire task and cross multiplies to solve for the percentage of the shed built by Jack by the time Kyle gets it completed:

Kyle / Jack ÷ 62.5 / 20 = 100 / x

62.5x = 2000 so

x = 32%

Therefore, when Kyle will complete the work the amount of the work done by Jack will be 32%.

You own 7 pairs of jeans and are taking 4 on vacation. In how many ways can you choose 4 pairs of jeans form the 7?

Answers

Answer:

35 ways

Step-by-step explanation:

The selection process in the given question can be referred to as combination, since 4 pairs of jeans are to be selected from the 7 pairs. There is no specific pattern of selecting the 4 pairs.

Thus, the selection can be done in 7[tex]C_{4}[/tex] ways.

7[tex]C_{4}[/tex] = [tex]\frac{7!}{(7-4)!4!}[/tex]

      = [tex]\frac{7!}{3!4!}[/tex]

      = [tex]\frac{7*6*5*4!}{3*2!4!}[/tex]

      = 7 x 5

      = 35

Therefore, 4 pairs of jeans can be selected from 7 pairs in 35 ways.

You and a friend decide to take a road trip. You drive an average speed of 70 mph and your friend drives an average of 75 mph. You want to drive at least 500 miles per day. You also plan to spend no more than 10 hours driving each day. Which of the following is a system of linear inequalities that represents this situation? Let x = number of hours you drive and let y represent the number of hours your friend will drive.

Answers

Given:

your speed = 70 mph

Your friend's speed = 75 mph

You want to drive at least 500 miles per day.

You also plan to spend no more than 10 hours driving each day.

To find:

The system of linear inequalities that represents this situation.

Solution:

Let x be the number of hours you drive and let y represents the number of hours your friend will drive.

You also plan to spend no more than 10 hours driving each day.

[tex]x+y\leq 10[/tex]

Your speed is 70 mph and your friend's speed is 75 mph. So, the distance covered in x and y hours are 70x miles and 75y miles respectively.

You want to drive at least 500 miles per day. So, the total distance must be greater than or equal to 500.

[tex]70x+75y\geq 500[/tex]

[tex]5(14x+15y)\geq 500[/tex]

Divide both sides by 5.

[tex]14x+15y\geq 100[/tex]

Therefore, the required system of inequalities has two inequalities [tex]x+y\leq 10[/tex] and [tex]14x+15y\geq 100[/tex].

Can someone help me with this math homework please!

Answers

Answer:

2) F(x)>0 (-infinity,-4)

3) x goes to + infinity and the line goes to + infinity

4) 56

5) first choice

Step-by-step explanation:

1) see where the line touches the x-axis and no where else. There are 3 points where the line does touch them and those are the answers.

2) interval is usually the space of where you check. They said (-infinity,-4) so anything to the left of x= -4. Identify where the x-axis is and decide if the line is above or below it. Below= - Above= +

3) Line goes to top right. We need to understand that the right on the x-axis is positive and up on the y-axis is positive. so if it is going to the right and up, its going to (+infinity, +infinity)

4) Local maximum over interval. Like What I said for #2, its where you check. So check everything from x= -3 to x=1.5 and see the highest point as a y value. In this case, the highest or biggest number is 56.

5) Again intervals, You check the numbers and identify where the x-axis is and see if it is above or below

Did you know that all 50 states in the United States have some sort of state fair? Fairs and carnivals
include a variety of games of chance that aren't typically "fair." What does it mean for a game to be fair? In
this task, you'll analyze different scenarios to determine fairness. You will use probability and expected
value to make these determinations. You will also use these concepts to make decisions.
As you complete the assignment, keep this question in mind:

Answers

Tanya should play The second game to win more.

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, Tanya is considering playing a game at the fair. There are three different ones to choose from, and it costs $2 to play a game. The probabilities associated with the games are given in the table.

From the general formula of weighted possibility :

Total weighted possibility = Sum of the weighted probability of desired outcomes - the weighted possibility of undesired outcomes

In our case,

For first game

The sum of the weighted possibility of desired outcomes = 0.20*1 + 0.25 *4

The sum of the weighted possibility of desired outcomes = 1.20

the weighted possibility of undesired outcomes = 0.55 * 2 = 1.10

Thus,

Total weighted desired possibility = 1.20 - 1.10

Total weighted desired possibility = 0.10

For second game

The sum of the weighted possibility of desired outcomes =0.35*1 + 0.50 *4

The sum of the weighted possibility of desired outcomes = 2.35

the weighted possibility of undesired outcomes = 0.15 * 2 = 0.30

Thus,

Total weighted desired possibility = 2.35 - 0.30

Total weighted desired possibility =  2.05

For third game

The sum of the weighted possibility of desired outcomes = 0.60*1 + 0.20*4

The sum of the weighted possibility of desired outcomes = 1.40

the weighted possibility of undesired outcomes = 0.20 * 2 = 0.40

Thus,

Total weighted desired possibility =1.40 - 0.40

Total weighted desired possibility = 1

Therefore, Tanya should play The second game to win more.

Answer:

Step-by-step explanation:

It should be 9x² not x²

p = (3x + 1) and q = (3x - 1)

pq + 1 = (3x + 1)(3x - 1) + 1

= (9x² - 3x + 3x - 1) + 1

A bag contains 10 marbles,7 of which are black and 3 are red.three marbles are drawn at one after the other.find the probability of choosing at most two black marbles.​

Answers

Answer:  17/24

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

Explanation:

We have these four cases or possible outcomes

Case 1) We select 0 black marbles and 3 red marbles.Case 2) We select 1 black marble and 2 red marbles.Case 3) We select 2 black marbles and 1 red marble.Case 4) We select 3 black marbles and 0 red marbles.

Let's calculate the probability for case 4.

There are 7 black marbles out of 10 total. The probability of picking black is 7/10. If no replacement is made, then 6/9 is the probability of picking black again (subtract 1 from the numerator and denominator separately). Finally, 5/8 is the probability of getting black a third time.

The probability of getting 3 black marbles in a row is

(7/10)*(6/9)*(5/8) = (7*6*5)/(10*9*8) = 210/720 = 7/24.

That fraction 7/24 means that if you had 24 chances, then you expect about 7 of them will lead to getting three black marbles in a row (aka case 4). Therefore, 24-7 = 17 occurrences are expected where we get cases 1 through 3 occur in some fashion (pick one case only).

Notice how cases 1 through 3 encapsulate the phrasing "at most 2 black marbles" which is another way of saying "2 black marbles is the highest we can go".

So that's why the answer is 17/24.
