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:

The Answers are: 1) -3pi/2 & 4) pi/2

Step-by-step explanation:

I got it right!

[tex]~~~~~~ \textit{Continuously Compounding Interest Earned Amount} \\\\ A=Pe^{rt}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$100\\ r=rate\to 6.5\%\to \frac{6.5}{100}\dotfill &0.065\\ t=years\dotfill &6 \end{cases} \\\\\\ A=100e^{0.065\cdot 6}\implies A=100e^{0.39}\implies A\approx 147.70[/tex]

The balance of your account after 6 years with continuous compounding would be approximately $147.56.

To calculate the balance of your account after 6 years with continuous compounding, you can use the formula:

[tex]\[ A = P \times e^{rt} \][/tex]

where:

[tex]\( A \) =[/tex] the balance after [tex]\( t \)[/tex] years

[tex]\( P \) =[/tex]the principal amount (initial investment) = $100

[tex]\( r \) =[/tex] the annual interest rate (in decimal form) = 6.5% = 0.065

[tex]\( t \) =[/tex] the number of years = 6

[tex]\( e \) =[/tex] Euler's number (approximately 2.71828)

Let's plug in the values and calculate the balance:

[tex]\[ A = 100 \times e^{0.065 \times 6} \]\[ A = 100 \times e^{0.39} \]\[ A = 100 \times 1.47560080488 \]\[ A = 147.560080488 \][/tex]

Rounding the answer to the nearest hundredth:

[tex]\[ A \approx $147.56 \][/tex]

So, the balance of your account after 6 years with continuous compounding would be approximately $147.56.

b = -1

Step-by-step explanation:

[tex]g(x)=ax^2-b \quad \quad \textsf{(where }\:a\:\textsf{ and }\:b\:\textsf{ are real numbers)}[/tex]

Create 2 equations with b as the subject using the given information.

By : Modern Einstein

Answer:

y = 2x + 10

Step-by-step explanation:

Hi there!

We are given the points (-7, -4) and (-6, -2) and we want to write the equation of the line that passes through these points in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

First, we need to find the slope (m) of the line

The slope can be calculated from 2 points using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to find the slope, but let's label the values of the points to avoid any confusion & and mistakes

[tex]x_1= -7\\y_1=-4\\x_2=-6\\y_2=-2[/tex]

Substitute these values into the formula (note: remember that the formula has subtraction in it!)

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-2--4}{-6--7}[/tex]

Simplify

m=[tex]\frac{-2+4}{-6+7}[/tex]

Add the numbers

m=[tex]\frac{2}{1}[/tex]

Divide

m=2

The slope of the line is 2

We can substitute that in:

y = 2x + b

Now we need to find b

As the equation passes through both  (-7,-4) and (-6,-2), we can use either point to help solve for b

Taking (-6, -2) for example:

Substitute -6 as x and -2 as y into the equation.

-2 = 2(-6) + b

Multiply

-2 = -12 + b

Add 12 to both sides

-2 = -12 + b

+12  +12

___________

10 = b

Substitute 10 as b.

y = 2x + 10

Hope this helps!
