We can use the Pythagorean Theorem (below) to solve for x, the shorter leg of the right triangle.

The Pythagorean Theorem

[tex]\bullet\,\,\,\boldsymbol{a^2+b^2=c^2.}\bullet[/tex]. in which a and b are the two legs of the right triangle, and c is the hypotenuse, the longest side of the right triangle. This side is opposite the right angle ([tex]90\textdegree[/tex]).

In this problem we're given

Hypotenuse = [tex]\sqrt{218}[/tex]Long Leg = [tex]\boldsymbol{13}[/tex].

and we're asked to solve for x, the short leg.

So we stick in the values into the formula.

[tex]\boldsymbol{13^2+b^2=(\sqrt{218})^2}[/tex]

Simplify!

[tex]\boldsymbol{169+b^2=218}[/tex]

Simplify!

[tex]\boldsymbol{b^2=218-169}[/tex]

[tex]\boldsymbol{b^2=49}[/tex]

Next, take the square root of both sides

[tex]\boldsymbol{b=7}[/tex]

[tex]\boldsymbol{\therefore,\:the\:answer\:is\:option\:a}[/tex]

Hope that this helped! Best wishes.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 4 to 5. If there were 4160 no votes, what was the total number of votes?

Answers

Answer:

The total number of voters was 7488

Step-by-step explanation:

Let us solve this question using the ratio method

∵ The ratio of yes votes to no votes was 4 to 5

∵ There were 4160 no votes

∵ We need to find the total number of votes

∵ The total of the ratio = 4 + 5 = 9

→ By using the ratio method

→ YES    :    NO    :    Total

→ 4         :    5       :     9

→  x        :   4160  :     y

→ By using the cross multiplication

5 × y = 4160 × 9

∴ 5y = 37440

→ Divide both sides by 5 to find y

∵ [tex]\frac{5y}{5}[/tex] = [tex]\frac{37440}{5}[/tex]

y = 7488

∵ y represents the total number of voters

The total number of voters was 7488

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.
