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.

Write an equation in slope-intercept form for each table below.


Show how you found the slope and Y-intercept

Answers

Answer:

i.  y=2x

ii. y=x+6

iii. y=-2x-6

iiii. y=-4x+3

iiiii. y=4x-3

Step-by-step explanation:

You can find the slope of the line by putting y2-y1/x2-x1

All you have to do is choose 2 points. Y2 is the second number y and x2 is the second number x. Y1 is the first number y and X1 is the first number X. To find y-intercept you look on the table and see where X is 0 and Y is any number that is the y-int. For example 5 there is no X=0 on the table so you put it in the point slope formula which is y-y1=m(x-x1) where you use the points from the slope. You multiply m to x and m to x1 where you will end up with y-y1=mx+mx1 then you add the y1 to mx1 where you will get the y intercept

Determine the ratio equivalent to cos Q.

Answers

Answer:   cos(Q) = 5/13

=========================================================

Work Shown:

The triangles are similar, which means the corresponding angles are congruent. In this case, we can say angle K = angle Q. Note how K and Q are the second letters of JKL and PQR respectively. The order matters.

Because angle K = angle Q, we can use information from triangle JKL to get information about triangle PQR.

We can say the following:

cos(angle) = adjacent/hypotenuse

cos(K) = LK/JK

cos(K) = 5/13

cos(Q) = 5/13 ... plug in K = Q

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).

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

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.
