the distance from Layana’s home to the store is 4 units .

<u>Step-by-step explanation:</u>

We know that distance between two points P(x_1,y_1),Q(x_2,y_2) is given by :

⇒ D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

According to question we have ,

P(x_1,y_1 )= (2\frac{2}{3}, 7\frac{1}{3}) = (\frac{8}{3},\frac{22}{3})\\Q(x_2,y_2) =( -1\frac{1}{3}, 7\frac{1}{3}) = ( -\frac{4}{3}, \frac{22}{3})

Putting these values in above equation we get :

⇒ D = \sqrt{(-\frac{4}{3}-\frac{8}{3})^2+(\frac{22}{3}-\frac{22}{3})^2}

⇒ D = \sqrt{(-\frac{12}{3})^2}

⇒ D =\frac{12}{3}

⇒ D =4

Therefore , the distance from Layana’s home to the store is 4 units .

The distance between Layana's house and store is 4 units.

<u>Explanation:</u>

Given:

Coordinates of Layana's house = (2\frac{2}{3} , 7\frac{1}{3})

Coordinates of the store = (-1\frac{1}{3}, 7\frac{1}{3})

It can also be written as:

Coordinates of Layana's house = (\frac{8}{3}  , \frac{22}{3})

Coordinates of the store = (-\frac{4}{3}, \frac{22}{3})

The distance between the house and the shop is:

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}

On substituting the value we get:

d = \sqrt{(\frac{-4 - 8}{3} )^2 + (\frac{22-22}{3} )^2} \\\\d = \sqrt{\frac{144}{9} } \\\\d = \frac{12}{3} \\\\d = 4 units

Therefore, the distance between Layana's house and store is 4 units.

What happens to the interval as the level of confidence is​ changed? Explain why this is a logical result.
Elan Coil [88]

Answer with explanation:

A x% confidence interval interprets the percentage of certainty that a person can believe that the true population parameter.

It is also represented as Point estimate ± Margin of error

Confidence level is proportional to the Margin of error.

  • As confidence level increases the error bound increases that makes the confidence interval broader.
  • As confidence level decreases the error bound decreases , making the confidence interval narrower.

What is the sum of the geometric series
Sergio039 [100]
Answer: 2343 / 256

Explanation

I will do this for you in two forms: 1) adding each term, and 2) using the general formula for the sum of geometric series.

1) Adding the terms:

 4
∑ 3 (3/4)^i = 3 (3/4)^0 + 3 (3/4)^1 + 3 (3/4)^2 + 3 (3/4)^3 + 3 (3/4)^4
i=0

= 3 + 9/4 + 27/16 + 81/64 + 243/256 = [256*3 + 27*16 + 64*9 + 4*81 + 243] / 256 =

= 2343 / 256

2) Using the formula:

n-1
∑ A (r^i) = A [1 - r^(n) ] / [ 1 - r]
i=0

Here n - 1 = 4 => n = 5

r = 3/4

A = 3

Therefore the sum is 3 [ 1 - (3/4)^5 ] / [ 1 - (3/4) ] =

= 3 [ 1 - (3^5) / (4^5) ] / [ 1/4 ] = 3 { [ (4^5) - (3^5) ] / (4^5) } / {1/4} =

= (3 * 781) / (4^5) / (1/4) =  3 * 781 / (4^4) = 2343 / 256

So, no doubt, the answer is 2343 / 256

What is the product of [x-(4+13i)][x-(4+13i)]
Luden [163]

Answer:

x^2 - (4+13i)^2

Step-by-step explanation:

This product has the form (a-b)(a+b), which is a 'special product' equal to a^2 - b^2.  Following this pattern, [x-(4+13i)][x-(4+13i)] = x^2 - (4+13i)^2.  The 2nd term could be expanded if desired, but the above result is the most compact one possible.
