Answer:

  KK KL KM KN KP LL LM LN LP MM MN MP NN NP PP

Step-by-step explanation:

Instead of starting with adjacent letters in the list, we start with the same letter. There are 15 possible pairs.

  KK KL KM KN KP LL LM LN LP MM MN MP NN NP PP

Additional comment

We leave out pairs with letters previous, because you've said KL is the same as LK, and KL has already been listed. The problem with this list is that it misstates the probabilities of randomly obtaining a given pair. It is not 1/15, but is 2/25 for all but letter duplicates. For duplicates (KK), the probability is 1/25, not 1/15.

Answer:

1/6

Step-by-step explanation:

Probability that any arrives on time = 2/3

Probability that teaa arrives on time = 3/4

Probability that teas will not arrive in time = 1 - P(tess arrives on time) = 1 - 3/4 = 1/4

Hence,

The probability that Amy arrives in time and tess does not equals

2/3 * 1/4 = (2*1) / (3*4) = 2 / 12 = 1/6

Using it's concept, it is found that there is a 0.1667 = 16.67% probability that Amy will arrive on time while Tess will not.

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

In this problem:

Since they are independent, we multiply them, hence:

[tex]P = \frac{2}{3} \times \frac{1}{4} = \frac{2}{12} = 0.1667[/tex]

0.1667 = 16.67% probability that Amy will arrive on time while Tess will not.

Answer:

x = ±8

Step-by-step explanation:

The given equation is :

[tex]3x^2-192=0[/tex]

We can use the Square root Property to solve it.

Adding 192 both sides,

[tex]3x^2-192=0\\\\3x^2=192[/tex]

Dividing both sides by 3.

[tex]x^2=64\\\\x=\sqrt{64} \\\\x=\pm 8[/tex]

The expressions that are the result of decreasing x by 80% will be (1 - 0.80)x, x - (80/100)x, and (20/100)x. Then the correct options are A, C, and E.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The expressions that are the result of decreasing x by 80%.

We know that if something is decreased by a percentage p% then the percentage is written as (1 - p%). Then the expression is written as,

⇒ [(100 - 80) / 100]x

Then the expression can be written as,

⇒ [(100 - 80) / 100]x

⇒ x - (80/100)x

⇒ x - 0.80x

⇒ (1 - 0.80)x

⇒ 0.20x

⇒ (20/100)x

The expressions that are the result of decreasing x by 80% will be (1 - 0.80)x, x - (80/100)x, and (20/100)x. Then the correct options are A, C, and E.

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

Center: (−2, −5); radius= 1

This means that [tex]x_0 = -2, y_0 = -5, r = 1[/tex]. So

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - (-2))^2 + (y - (-5))^2 = 1^2[/tex]

[tex](x + 2)^2 + (y + 5)^2 = 1[/tex]

Answer:

Number of bacteria when t = 10 min is 3,000

Step-by-step explanation:

Given:

Number of bacteria in a culture by equation

Q(t) = 2(729^t)

Value of t = 10 min = 10 / 60 = 0.1667 hour

where t is number of hours

Find:

Number of bacteria when t = 0.1667 hour

Computation:

Given equation

Q(t) = 2(729^t)

Put t = 0.1667

Q(10) = 2(729⁰'¹⁶⁶⁷)

We know that;

a⁰ = 1

So,

Q(0.1667) = 2(729⁰)

Q(0.1667) = 3

Number of bacteria when t = 0 is 3,000

The 99% confidence interval for the proportion of songs on her phone that are by a female artist will be given below. Then the correct option is A.

[tex]0.4 \pm 2.58 \times \dfrac{0.4(1-0.4)}{50}[/tex]

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

Della has over 500 songs on her mobile phone, and she wants to estimate what proportion of the songs are by a female artist.

She takes an SRS of 50 songs on her phone and finds that 20 of the songs sampled are by a female artist.

The 99% confidence interval for the proportion of songs on her phone that are by a female artist will be

[tex]\rm x = 20\\\\n = 50 \\\\p = \dfrac{20}{50} = 0.4\\\\z= 99\% \ confidence\ interval = 2.58[/tex]

Then we know that

[tex]p\pm z \times \dfrac{p(1-p)}{n}\\\\0.4 \pm 2.58 \times \dfrac{0.4(1-0.4)}{50}\\\\0.4 \pm 2.58 \times \dfrac{0.4*0.6}{50}\\\\0.4 \pm 0.012384[/tex]

Answer:

y = 1/2x + 10  

Step-by-step explanation:

I'm not sure if this is right but:

First you work out the gradient of the line which is the difference in y divided by the difference in x:  

Gradient = (14 - 11) ÷ (8 - 2) = 3 ÷ 6 = 1/2    

the gradient is 1/2 so you'd write that as: y= 1/2x + c

Then you need to work out the y-intercept ( c )  

You do this by substitution:

14 = 1/2(8) + c

14 = 4 + c

c = 10

So the y-intercept is 10 so you'd write that as:

y = 1/2x + 10

Approximately 73 Great Danes weigh more than 125.8 lbs.

Mean [tex]\mu[/tex]=115 lb.

Standard deviation [tex]\sigma[/tex] =5.4 lb.

Z-score depicts how much a given value differs from the standard deviation.

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

[tex]z=\frac{125.8-115}{5.4}[/tex]

[tex]z=2[/tex]

From the standard normal table P-value corresponding to z=2 i.e. P(x>125.8) = 0.02275

Total population =3200

3200*0.02275 = 72.8 ≈73

Answer:

  a) at t=12, Whitney is speeding up

  b) 13/48 = 0.2704833 . . . miles/min; not a good measure

Step-by-step explanation:

a) At t=12, Whitney's velocity is -0.2 miles/min and is decreasing. That is, the magnitude of her velocity (speed) is increasing. Whitney is speeding up at t=12.

__

b) The (signed) area under the curve, divided by the time period (24 min) will give Whitney's average velocity. It can be found by using the formulas for area of a trapezoid and triangle.

  distance 0-11 = 1/2(11 +3)(0.8) = 5.6 miles

  distance 11-16 = 1/2(5)(-0.6) = -1.5 miles

  distance 16-24 = 1/2(8)(0.6 = 2.4 miles

Whitney's average velocity is ...

  (5.6 -1.5 +2.4)mi/(24 min) = 6.5 mi/(24 min) = (13/48) mi/min ≈ 0.270 mi/min

The laws of physics tell us that no work is being done if velocity is constant. Hence, the strenuousness of Whitney's pedaling depends on the acceleration she is maintaining. The average velocity measure tells nothing of that, so is a poor measure of how strenuously Whitney is pedaling.
