Answer:

a. 7% probability that the selected individual owns shares in the balanced fund.

b. 31% probability that the individual owns shares in a bond fund.

c. 58% probability that the selected individual does not own shares in a stock fund

Step-by-step explanation:

a. What is the probability that the selected individual owns shares in the balanced fund?

7% of the individuals owns shares in the balanced fund, so 7% probability that the selected individual owns shares in the balanced fund.

b. What is the probability that the individual owns shares in a bond fund?

Bond funds (short, intermediate, and long-term):

15%(short-term) + 11%(intermediate-term) + 5%(long-term)

15%+11%+5% = 31%

31% probability that the individual owns shares in a bond fund.

c. What is the probability that the selected individual does not own shares in a stock fund?

Anything but moderate and high risk stock%.

The sum of all probabilities is 100%.

18% + 24% = 42% own stock fund.

100 - 42 = 58%

58% probability that the selected individual does not own shares in a stock fund

The number, such that the geometric mean of the number and four times the number is 22, will be 11.

The arithmetic mean of two numbers [a] and [b] is equal to (a + b)/2  and their geometric mean is equal to  [tex]\sqrt{ab}[/tex]

We have the geometric mean of a number and four times the number is 22.

According to the question, we can write -

G.M. = [tex]\sqrt{ab}[/tex]

Assume that the number is [x]. Then the second number will be [4x]. So -

22 = √4x²

22 = √(2x)²

2x = 22

x = 11

Therefore, the number, such that the geometric mean of the number and four times the number is 22, will be 11.

Answer:

x=21

Step-by-step explanation:

69+90= 159

180-159=21

The geometric sequence is a sequence with a common ratio. The common ratio is the ratio between the succeeding term and the preceding term of a sequence and must be equal to a constant k.

Given a sequence 2, 4, 8, 16... This sequence is geometric in nature because of a constant common ratio of 2.'

Common ratio = 4/2 = 8/4 = 2

Hence a geometric sequence is characterized by its common ratio

Answer:

1) D and R are NOT independent events

2) The probability of electing a Republican president and an economic decline in 2020 is 0.224

3) If we experience an economic decline in 2016, the probability that a Republican president will have been elected in 2020 is 0.9739

4) the probability of economic decline or a Republican president elected in 2020 or both is 0.646

Step-by-step explanation:

Let "D" represent the event of an economic decline, and "R" represent the event of election of a Republican president

Given that;

P(D) = 0.23

P(R) = 0.64

Conditional P(D | R) =  0.35

1) Are R and D independent events?

we know that two events A & B are independent events if; P(B | A) = P(B)

here, P(D | R) =  0.35 and P(D) = 0.23

so; P(D | R) ≠ P(D)

Therefore D and R are NOT independent events

2) The probability of electing a Republican president and an economic decline in 2020;

we know that;

P(D | R) = P(D ∩ R) / P(R)

we substitute

0.35 = P(D ∩ R) / 0.64

P(D ∩ R) = 0.35 × 0.64

P(D ∩ R)  = 0.224

Therefore, The probability of electing a Republican president and an economic decline in 2020 is 0.224

3) If we experience an economic decline in 2016, what is the probability that a Republican president will have been elected in 2020?

P(R | D) = P(D ∩ R) / P(D)

we substitute

P(R | D) = 0.224 / 0.23

P(R | D) = 0.9739

Therefore, If we experience an economic decline in 2016, the probability that a Republican president will have been elected in 2020 is 0.9739

4) the probability of economic decline or a Republican president elected in 2020 or both

P(D ∪ R) = P(D) + P(R) - P(D ∩ R)

we subtitute

P(D ∪ R) = 0.23 + 0.64 - 0.224

P(D ∪ R)  = 0.646

Therefore, the probability of economic decline or a Republican president elected in 2020 or both is 0.646

Answer:

mean

Step-by-step explanation:

The method to summarize the data will be mean

The mean of the laps of swim team is 84.1 laps

What is Mean?

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the data be represented by the set A

Let the mean of the data set be M

The value of set A = { 77 , 79 , 80 , 82 , 84 , 85 , 86 , 87 , 90 , 91 }

The total number of data elements in the set = 10

Now , since all the data elements are distributed normally and does have a central point

So , it follows normal distribution

Therefore , the mean of the data will be

Mean M = Sum of Values / Number of Values

Mean = ( 77 + 79 + 80 + 82 + 84 + 85 + 86 + 87 + 90 + 91 ) / 10

Mean = 841 / 10

Mean M = 84.1 laps

Therefore , the value of M is 84.1

Hence , The method to summarize the data will be mean

The mean of the laps of swim team is 84.1 laps

Answer: use division

Step-by-step explanation:

Answer:

The major difference between square and rectangle is that a square has all its sides equal whereas a rectangle has its opposite sides equal. In Geometry, we have learnt different types of shapes such as square, rectangle, cube, cone, cylinder, parallelogram, rhombus, and so on.

All these shapes can fall under any one of the categories such as two-dimensional shapes or three-dimensional shapes. All the shapes can share a few characteristics. But they have many different characteristics properties that differentiate the shapes from each other. In this article, let us discuss the difference between a rectangle and a square in detail.

Answer:

76 cm cubed

Step-by-step explanation:

2 x 2 x 4 = 16 cm cubed

3 x 4 x 5 = 60 cm cubed

Solution :

It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :

1. [tex]$P(x) \geq 0$[/tex]

2. [tex]$\sum_z P(x) = 1$[/tex]

Now consider,

[tex]$\sum_z P(x) = 1$[/tex]

⇒ [tex]$P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)+P(x=5)=1$[/tex]

⇒ [tex]$0.61+T+0.14+0.01+0.01+0.03=1$[/tex]

⇒ [tex]$0.8+T=1$[/tex]

⇒ [tex]$T=1-0.8$[/tex]

       = 0.2

Therefore, the value of T is 0.2

Thus, option (c) is correct.

Answer:

C(5)= $13,172.05

Step-by-step explanation:

To calculate C(t), we need to divide the formula into two equations:

C(t) =b(t) +h(t)

b(t)= PV*(1+i)^n

n= number of months

i= monthly interest rate

PV= initial investment

h(t)= montlhy deposit* number of months

Now, for C(5); I assume its 5 years:

i= 0.036/12= 0.003

n= 5*12= 60

C(5)= 9,000*(1.003^60) + 40*60

C(5)= $13,172.05

Given:

The functions are

[tex]f(x)=-5x^2+4x-9[/tex]

[tex]g(x)=8x^2-3x-4[/tex]

To find:

The value of (f+g)(x).

Solution:

We know that,

[tex](f+g)(x)=f(x)+g(x)[/tex]

Putting the given functions, we get

[tex](f+g)(x)=-5x^2+4x-9+8x^2-3x-4[/tex]

On combining like terms, we get

[tex](f+g)(x)=(-5x^2+8x^2)+(4x-3x)+(-9-4)[/tex]

[tex](f+g)(x)=3x^2+x-13[/tex]

Therefore, the required function is [tex](f+g)(x)=3x^2+x-13[/tex].
