Answer:

In economics, a portfolio is a term for a specific set of stocks, bonds, shares, and other securities owned by an investor. In general, the investor seeks to compile and diversify a portfolio of securities that offers maximum profitability and at the same time is diverse, in order to minimize possible risks. In general, these types of portfolios are considered efficient, as they do not leave the investment risk tied to a single factor. However, these two goals often go against each other, so the composition of the portfolio means a certain compromise.

Answer:

We are 90% confident that the population mean number of children per adult is between 1.8 to 1.9.

Step-by-step explanation:

The confidence interval for population mean is given by:-

[tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex], where n= sample size, [tex]\overline{x}[/tex] = sample mean, z* = critical value for confidence level, [tex]\sigma[/tex]= standard deviation.

z*  for 90% confidence level = 1.645

As per given, the required confidence interval is

[tex]1.87\pm (1.645)\dfrac{1.64}{\sqrt{1494}}\\\\\approx1.87\pm0.070\\\\=(1.87-0.07,\ 1.87+0.07)\\\\=(1.8, 1.94)[/tex]

Hence, We are 90% confident that the population mean number of children per adult is between 1.8 to 1.9.

• Hypotenuse (H) = 15 in

• Base (B) = 12 in

• Perpendicular (P) [x]

By using pythagoras property,

[tex] \longmapsto \sf { H^2 =B^2 + P^2 } [/tex]

[tex] \longmapsto \sf { (15)^2 =(12)^2 +(x)^2 } [/tex]

[tex] \longmapsto \sf { x^2 = (15)^2 - (12)^2 } [/tex]

[tex] \longmapsto \sf { x^2 = 225 - 144 } [/tex]

[tex] \longmapsto \sf { x^2 = 81 } [/tex]

[tex] \longmapsto \sf { x = \sqrt{81} } [/tex]

[tex] \longmapsto \sf \red { x = 9 \: in} [/tex]

So, the value of x (perpendicular) is 9 in.

Answer:

this simplified would be 2x+5y+15

Step-by-step explanation:

Answer:

-9/4

Step-by-step explanation:

First you need to change the equation to slope-intercept form (y=mx+b). To start, you need to get y alone, so subtract 9x on both sides to give you 4y=-9x+7. Next, divide 4 from both sides giving you y=-9/4x +7/4. The slope is the coefficient of x.

Answer:

B. 45

Step-by-step explanation:

we know the sum of both angles is 90 because of the small sqaure in the corner.

90 = 2x+20

70 = 2x

45 = x

Answer:

35

Step-by-step explanation:

Because of the box in the graph, you can tell that this is a 90-degree angle

2x means the next angle will be twice of the answer choice number

because the end product must be 70 the answer must be 35

35 x 2 = 70

Answer:

X = 22

Step-by-step explanation:

This is a right triangle which means the angles add up to 90° total. So if 1 side is 15 and another side is 53 then 15 + 53 = 68 and 90 - 68 = 22 so X = 22 which is the missing side.

Answer on Khan

Answer:

B/2

Step-by-step explanation:

Jeez better not get this wrong... anyway, to start off the total is 19 books. Adding 5 then adding 3, She returned 8 books to the 19 she checked out. Uhhhh no clear answer.

NOT the first one cause 8 isn't the total. Don't think it would be the last one cause that's no fun. So it's either the second or the third one. The third one also makes no sense cause it only includes the returns from yesterday. I'm going with the second one

Answer:

Step-by-step explanation:

Proper equation would be:

This doesn't match any answer options, so the correct option is the last one

Answer:

  BE = 266 2/3

  PE = 233 1/3

Step-by-step explanation:

Part A: The figure has 3 triangles, all similar. In order of shortest-to-longest side lengths, they are ...

  ΔBPE ~ ΔBCG ~ ΔGRE

__

Part B: They can be declared similar by the AA postulate. For BPE and BCG, the angles at B are vertical angles, so are congruent. The angles at C and G are alternate interior angles, so are congruent.

For triangles BPE and GRE, angle E is congruent to itself, The angles at R and P are corresponding angles, so are congruent.

(Remember, GRPC is a parallelogram, so any line in the figure is a transversal crossing parallel lines.)

__

Part C:

From parts A and B, we know ΔBPE ~ ΔBCG. Corresponding sides are proportional:

  BP/BC = BE/BG = PE/CG

  200/300 = BE/400 = PE/350

  BE = (400)(2/3) = 266 2/3

  PE = (350)(2/3) = 233 1/3

Answer:

7

Step-by-step explanation:

area of parallelogram = l* h

91 = 13 * h

91/13 = h = 7 cm

Answer:

I believe it is 7

Step-by-step explanation:

area is length times width, so if you do opposite equations, and divide 91 by 13, that will be your answer. 7.

Answer:

The quadrilateral ABCD is a square.

Step-by-step explanation:

According to the statement, AB, BC, CD and DA are the sides of the quadrilateral, whereas DB and AC are its diagonals. If we know that [tex]x = 7[/tex], [tex]AB = 4\cdot x - 2[/tex], [tex]BC = 2\cdot x + 12[/tex], [tex]DC = 3\cdot x +5[/tex], [tex]AD = 6\cdot x -16[/tex], [tex]AC = 4\cdot x + 12[/tex] and [tex]DB = 8\cdot x -10[/tex], the lengths of each line segment are respectively:

Sides

[tex]AB = 4\cdot (7) -2[/tex]

[tex]AB = 26[/tex]

[tex]BC = 2\cdot (7) +12[/tex]

[tex]BC = 26[/tex]

[tex]DC = 3\cdot (7) +5[/tex]

[tex]DC = 26[/tex]

[tex]AD = 6\cdot (7) -16[/tex]

[tex]AD = 26[/tex]

Diagonals

[tex]AC = 4\cdot (7) +12[/tex]

[tex]AC = 40[/tex]

[tex]DB = 8\cdot (7) - 10[/tex]

[tex]DB = 40[/tex]

This information indicates that this quadrilateral is a square because of these characteristics:

1) All sides have the same length.

2) The ratio of any diagonal to any side is [tex]\sqrt{2}[/tex].

Answer:

A or B Ma'am or sir. Have an amazing day and good luck!!

Step-by-step explanation:

Answer:

12 and 53

Step-by-step explanation:

let 'x' = one number

let 'y' = other number

System of Equations:

x + y = 65

x - y = 41

Substitution Method:

x = 41 + y

41 + y + y = 65

2y = 24

y = 12

x + 12 = 65

x  = 53
