in our case we know

pi×r² = 78.5

3.14×r² = 78.5

r² = 78.5/3.14 = 25

Using the normal distribution, it is found that there is a 0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Normal Probability Distribution

In a normal distribution with mean  and standard deviation, the z-score of a measure X is given by:

[tex]Z=\dfrac{x-\mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are, respectively, given by and.

The probability of a random person on the street having an IQ score of less than 98 is the p-value of Z when X = 98, hence:

[tex]Z=\dfrac{x-\mu}{\sigma}[/tex]

[tex]Z=\dfrac{98-100}{15}[/tex]

[tex]Z=-0.13[/tex]

Has a p-value of 0.4483.

0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.

Answer:

A Circle

Step-by-step explanation:

Answer: 82

Step-by-step explanation:

Given the final amount of money available in Maddy's account, the interest rate and the time elapsed, the initial money her aunt invested was $15,000.

Interest is simply the amount of money a lender or financial institution receives for lending out money or pays for receiving money.

The formular for calculating compound interest is expressed as;

A = P(1 + r/n)^(n*t)

Where A is final amount, P is initial principal balance, r is interest rate, n is  number of times interest applied per time period and t is number of time periods elapsed.

Given the data in the question;

We substitute our given values into the expression above.

$39322  = P(1 + 0.055/1)^(1*18)

$39322  = P(1 + 0.055)^(18)

$39322  = P(1.055)^(18)

P = $39322 / (1.055)^(18)

P = $39322 / 2.621466

P = $15,000

Therefore, given the final amount of money available in Maddy's account, the interest rate and the time elapsed, the initial money her aunt invested was $15,000.

Answer:

[tex]y=6.50-0.25x[/tex]

Step-by-step explanation:

[tex]\textsf{let}\:(x_1,y_1)=(2,6)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(6,5)[/tex]

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{5-6}{6-2}=-0.25[/tex]

Point-slope form of linear equation:  [tex]y-y_1=m(x-x_1)[/tex]

(where m is the slope and (x₁, y₁) is a point on the line)

Substituting the found slope and a point on the line:

[tex]\implies y-6=-0.25(x-2)[/tex]

[tex]\implies y-6=-0.25x+0.5[/tex]

[tex]\implies y=-0.25x+6.5[/tex]

Rearranging the equation to match the answer options given:

Given that the variables are complex numbers, the value of the complex expression [tex]\frac{\gamma}{\alpha} +\bar{\frac{\alpha}{\beta}}[/tex] is -2

The given parameters are:

[tex]\alpha + \beta + \gamma = 0[/tex]

[tex]\frac{1}{\alpha} + \frac{1}{\beta} + \frac{1}{\gamma} = 0[/tex]

Rewrite the first equation as:

[tex]\alpha + \beta = - \gamma[/tex]

Take LCM in the second equation

[tex]\frac{\alpha + \beta}{\alpha \beta} + \frac{1}{\gamma} = 0[/tex]

So, we have:

[tex]\frac{ - \gamma}{\alpha \beta} + \frac{1}{\gamma} = 0[/tex]

Rewrite as:

[tex]\frac{1}{\gamma} = \frac{\gamma}{\alpha \beta}[/tex]

Multiply through by [tex]\alpha[/tex]

[tex]\frac{\alpha}{\gamma} = \frac{\gamma}{\beta}[/tex]

Inverse both sides

[tex]\frac{\gamma}{\alpha} = \frac{\beta}{\gamma}[/tex]

Make [tex]\beta[/tex] the subject in [tex]\alpha + \beta + \gamma = 0[/tex]

[tex]\beta =-(\alpha + \gamma)[/tex]

So, we have:

[tex]\frac{\gamma}{\alpha} = \frac{-(\alpha + \gamma)}{\gamma}[/tex]

Expand

[tex]\frac{\gamma}{\alpha} = -\frac{\alpha}{\gamma}- 1[/tex]

This gives

[tex]\frac{\gamma}{\alpha} +\frac{\alpha}{\gamma} = - 1[/tex]

Make [tex]\gamma[/tex] the subject in [tex]\alpha + \beta + \gamma = 0[/tex]

[tex]\gamma = -(\beta + \alpha)[/tex]

So, we have:

[tex]\frac{\gamma}{\alpha} +\frac{\alpha}{-(\beta + \alpha)} = - 1[/tex]

Split

[tex]\frac{\gamma}{\alpha} +\bar{\frac{\alpha}{\beta}} + \frac{\alpha}{\alpha} = - 1[/tex]

Evaluate the quotient

[tex]\frac{\gamma}{\alpha} +\bar{\frac{\alpha}{\beta}} + 1 = - 1[/tex]

Subtract 1 from both sides

[tex]\frac{\gamma}{\alpha} +\bar{\frac{\alpha}{\beta}} = - 2[/tex]

Hence, the value of [tex]\frac{\gamma}{\alpha} +\bar{\frac{\alpha}{\beta}}[/tex] is -2

Answer:

Step-by-step explanation:

Solve:

       [tex]\rule{250}{2}[/tex]

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Given question:-}}}[/tex]

    Solve 2=2+g/4

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]

When solving an equation, we need to make sure all variables are on the left-hand side, and all numbers are on the right.

Since we have numbers on both sides, we need to move them to one side, as follows:-

[tex]\Longrightarrow\sf{2-2=g/4}[/tex]

[tex]\longrightarrow\sf{0=g/4}[/tex]

Now, we multiply by 4 on both sides to get rid of the fraction:-

[tex]\longrightarrow\sf{0\times4=g/4\times4}[/tex]

[tex]\longrightarrow\sf{0=g}[/tex]

So we conclude that g=0.

Answer:

g(x) = -|x| - 8

Step-by-step explanation:

Finding the values of a, h, and k :

a = slope of the line

h = any horizontal shift (left/right)

k = vertical shift (up/down)

Forming the equation :

⇒ g(x) = (-1)|x - 0| - 8

⇒ g(x) = -|x| - 8

Answer:

[tex]\large{\boxed{\sf y = -1|x-0| -8}}[/tex]
