Answers

Answer 1

Answer:

multiply by 25 also.

Step-by-step explanation:

If the scores are multiplied by 25, that means that the mean will also multiply by 25. Since the mean and the scores all increased by 25 times, the standard deviation will increase by 25 times.

If instead, you added 25 (or any other number) to each score, then the standard deviation would not change. The mean and each score will increase by 25, bu the difference between them will not change.

The value of the expression is 0.0009.

We have,

To explain the process of evaluating (0.03)², we need to understand the concept of exponentiation and how it applies to decimal numbers.

When we raise a number to the power of 2 (or square it), we are essentially multiplying the number by itself.

In this case, we are squaring the decimal number 0.03.

To calculate (0.03)², we multiply 0.03 by itself:

= 0.03 x 0.03

= 0.0009

In decimal form,

0.03 squared is equal to 0.0009.

This process follows the general rule of exponentiation, where raising a number to a power means multiplying the base number by itself the specified number of times.

In this case, we square 0.03 by multiplying it by itself once, resulting in 0.0009.

Thus,

The value of the expression is 0.0009.

What is annuity?

An annuity is a financial product that provides an individual with a series of regular payments in exchange for an initial investment or a series of payments.

Annuities are commonly used to generate income in retirement, but they can also be used for other purposes, such as covering the future expenses of a dependent or providing a guaranteed income stream for a set period of time.

We can use the formula for the present value of an annuity to find the initial amount of the grant:

PV = A * ([tex](1 - (1 + r)^{(-n)[/tex]) / r)

Where PV is the present value, A is the annual payment, r is the annual interest rate, and n is the number of periods.

Substituting the given values, we get:

PV = 12,177.17 x ((1 - [tex](1 + 0.055)^{(-5)[/tex]) / 0.055)

PV ≈ 51,765.57

Rounding to the nearest dollar, the initial amount of the grant is $52,000.

Therefore, the answer is option (a).

According to a survey, 10% of Americans are afraid to fly. Suppose 1100 Americans are sampled. a) What is the probability that 121 or more americans in the survey are afraid to fly

Answers

Answer:

The probability that 121 or more Americans in the survey are afraid to fly is 0.1335.

Step-by-step explanation:

Let X denote the number of Americans afraid to fly.

The proportion of Americans afraid to fly is, p = 0.10/

A random sample of n = 1100 Americans are selected.

The random variable X follows a Binomial distribution with parameters n = 1100 and p = 0.10.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

 [tex]np=1100\times 0.10=110>10\\\\n(1-p)=1100\times (1-0.10)=990>10[/tex]

Thus, a Normal approximation to binomial can be applied.

So,  [tex]X\sim N(np,\ np(1-p))[/tex]

Compute the probability that 121 or more Americans in the survey are afraid to fly as follows:

[tex]P(X\geq 121)=P(\frac{X-np}{\sqrt{np(1-p)}}>\frac{121-110}{\sqrt{99}})\\\\=P(Z>1.11)\\\\=1-P(Z<1.11)\\\\=1-0.86650\\\\=0.1335[/tex]

Thus, the probability that 121 or more Americans in the survey are afraid to fly is 0.1335.

Complete Question

A circle with a 32 inch diameter has a central angle that intercepts an arc measuring approximately 75.36 inches. Which option describes how to determine this angles measure in radians?

A. Divide 75.36 by 16

B. Divide 75.36 by 32

C. Divide 16 by 75.36

D. Divide 32 by 75.36

Answer:

A. Divide 75.36 by 16

Step-by-step explanation:

The formula for Arc length is given as:

S = r θ

Where S = arc length

r = radius

We are told that:

Diameter of a circle = 32 inches

Radius of a circle = Diameter/2

= 32/2 = 16

Arc Length = 75.36 centimeters

The formula for Central angle =

θ = Central angle

θ = S/r

= 75.36/16

Option A is correct

The correct answer is option A. which is Divide 75.36 by 16

What is a circle?

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.

The formula for Arc length is given as:

S = r θ

Where S = arc length

r = radius

We are told that:

Diameter of a circle = 32 inches

The radius of a circle = Diameter/2

r = 32/2 = 16

Arc Length = 75.36 centimeters

The formula for Central angle =

θ = Central angle

θ = S/r

θ= 75.36/16

Therefore the correct answer is option A. which is Divide 75.36 by 16
