Step-by-step explanation:

If you think money, a question like this won't confuse you.

Which would you rather owe your parents

13 dollars or

10 dollars

The answer is obvious, isn't it? Most people would rather owe 10 dollars rather than 13.

The minus sign is the same as debt. - 13 is less than - 10. You are further and further in the hole when you owe 13 dollars than 10.

So the inequality is not correct. The answer is no.

So still with money

-13<- 11

13 > 11

you would rather have 13 dollars in your pocket than 10.

You would rather owe -10 dollars than - 13

We have been given that a of sofa prices are normally distributed with a mean of 2500 dollars and a standard deviation of 200 dollars.  A leather sofa has a price of 2410 dollars. We are asked to find the proportion of sofa prices that are higher than the price of the leather sofa.

First of all, we will find the z-score corresponding to sample score 2410.

[tex]z=\frac{x-\mu}{\sigma}[/tex]

[tex]z=\frac{2410-2500}{200}[/tex]

[tex]z=\frac{-90}{200}[/tex]

[tex]z=-0.45[/tex]

Now we need to find area under normal curve that is greater than z-score of [tex]-0.45[/tex] that is [tex]P(z>-0.45)[/tex].

Using formula [tex]P(z>a)=1-P(z<a)[/tex], we will get:

[tex]P(z>-0.45)=1-P(z<-0.45)[/tex]

Now we will find area under curve using normal distribution table.

[tex]P(z>-0.45)=1-0.32636[/tex]

[tex]P(z>-0.45)=0.67364[/tex]

Upon rounding to 4 decimal places, we will get:

[tex]P(z>-0.45)\approx 0.6736[/tex]

Therefore, approximately 0.6736 of sofa prices are higher than the price of the leather sofa.

0.6736

Answer:

x = 1 + i, x = 1 - i

Step-by-step explanation:

Make the second equation y = 3x - 1

Substitute: 3x - 1 = 1/2x^2 + 2x

Simplify: 6x - 2 = x^2 + 4x

x^2 + 4x + 2 = 6x

x^2 - 2x + 2 = 0

Complete the square: x^2 - 2x + 1 = - 1

(x - 1)^2 = -1

x - 1 = ± √-1

Take out the negative: x - 1 = ± i

x = 1 + i, x = 1 - i

i is for imaginary number

Answer:

False --> 1011 > 1100

True --> 110 + 111 == 1101

50 --> 1010 x 101

13 --> 110 + 111

17 --> 1010101 / 101

Step-by-step explanation:

This solution is achieved by calculating the binary operations, then finding either their values or the validity of their statements.

1011 > 1100 is the same as 11 > 12, which is false.

110 + 111 == 1101 is the same as 6 + 7 = 13, which is true.

1010 x 101 is the same as 10 x 5, which is 50.

110 + 111 is the same as 6 + 7, which is 13.

1010101 / 101 is the same as 85 / 5, which is 17.

Answer:

P+4=28, meaning that the original perimeter was 24

Step-by-step explanation:

Let's call the perimeter P.

Converting the words into an equation, you get:

P+4=28

Now, you can subtract 4 from both sides:

P+4-4=28-4

P=24

P(pick a girl) = 18/30 = 3/5 = 0.6

P(pick a girl 2 days in a row) = (0.6)^2 = 0.36

Answer:

C

Step-by-step explanation:

Since the figures have equal perimeters we can equate them, thus

4(2p - 4) = 4p + 36 ← distribute left side

8p - 16 = 4p + 36 ( subtract 4p from both sides )

4p - 16 = 36 ( add 16 to both sides )

4p = 52 ( divide both sides by 4 )

p = 13

Substitute p = 13 into either of the 2 expressions, then

4p + 36 = 4(13) + 36 = 52 + 38 = 88 → C

The value of perimeter is found as 88 units. The correct option is (C).

A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.

As per the question the perimeters are equal.

The following equation can be written as,

4(2p - 4) = 4p + 36

⇒ 8p - 16 = 4p + 36

⇒ 4p = 52

⇒ p = 13

Thus, the perimeter value can be obtained by substituting p = 13 in 4p + 36 as below,

⇒ 4 × 13 + 36 = 88

Hence, the perimeter value is 88 units.

Answer:

  empirical rule: 81.5%

  table or calculator: 81.9%

Step-by-step explanation:

The lower limit of the life range of interest has a z-score of ...

  z = (x -μ)/σ = (20,000 -30,000)/5,000 = -2

The upper limit has a z-score of ...

  z = (35,000 -30,000)/5,000 = 1

Empirical rule solution

The empirical rule tells you that 95% of the distribution lies within 2 standard deviations of the mean, so (100% -95%)/2 = 2.5% lie below z = -2. It also tells you 68% lie within 1 standard deviation of the mean, so (100% -68%)/2 = 16% lie above z = 1.

The fraction that lies within -2 to 1 standard deviations of the means is thus ...

  (100% -2.5% -16%) = 81.5%

The probability the tire has a life in the desired range is about 81.5%.

Calculator solution

A probability calculator for the Normal distribution tells you that ...

x = 126/999

Step-by-step explanation:

Let x = .126126126 repeating

Multiply each side by 1000

1000x = 126.126126126 repeating

subtract the first equation from the second

1000x = 126.126126126 repeating

- x = .126126126 repeating

999x = 126

Divide each side by 999

999x/999 = 126/999

x = 126/999

Answer:

14.14 ft

Step-by-step explanation:

In an isosceles triangle, the altitude and median is same. So the height divides the base AB equally such that AD = DB = 10, if the height is CD. So using Pythagoras theorem, we can find the hypotenuse AC in triangle ADC.

h² = b² + a²

AC² = AD² + CD²

AC² = 10² + 10²

AC² = 100 + 100

AC² = 200

AC = √200

AC ≈ 14.14 ft
