Answer 1

Answer:

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Step-by-step explanation:

Given

The attachment

Required

Express the area as a sum of stores and parking lots

First, calculate the area of the stores

[tex]Store\ A = 25\ by\ 10[/tex]

[tex]Store\ B = 25\ by\ w[/tex]

[tex]Stores\ A\ and\ B = 25\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_1 = 25 * (10 + w)[/tex]

Next, calculate the area of the parking lots

From the attachment, we have the following

[tex]Parking\ lot\ A = 13.5\ by\ 10[/tex]

[tex]Parking\ lot\ B = 13.5\ by\ w[/tex]

[tex]Parking\ lots\ A\ and\ B = 13.5\ by\ 10 + w[/tex]

The area is then calculated as:

[tex]A_2 = 13.5 * (10 + w)[/tex]

The area of the shopping centre is then calculated as:

[tex]Area = A_1 + A_2[/tex]

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Answer:

Step-by-step explanation:

The base (JL) is twice the length of the midline (MN), so you have ...

4x +34 = 2(5x -16)

4x +34 = 10x -32 . . . eliminate parentheses

66 = 6x . . . . . . . . add 32-4x

11 = x

Then the length of JL is ...

Find a Point-Slope equation for a line containing the given point and having the given slope.

(5, -1), m =1/5

Answers

Answer:

The point-slope equation for a line is:

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Step-by-step explanation:

Given

The point = (5, -1)m = 1/5

We know that the point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line

substituting the values m = 1/5 and the point (5, -1)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Thus, the point-slope equation for a line is:

[tex]y-\left(-1\right)=\frac{1}{5}\left(x-5\right)[/tex]

Assuming normality, construct the requested confidence interval.

A sociologist is interested in the age at which a mother has her first child. A random sample of 20 recent births yielded an average maternal age to be 30 years with a standard deviation of 6.2 years.

Construct a 99% confidence interval for the mean age at which a mother has her first child.

Can I have some help with solving this problem with a TI84 calculator?

Answers

Answer:

The appropriate response is "(26.03, 33.97)".

Step-by-step explanation:

The given values are:

Average maternal age,

[tex]\bar{x} = 30[/tex]

Standard deviation,

s = 6.2

Random sample,

n = 20

Now,

The degree of freedom will be:

⇒ [tex]df=n-1[/tex]

[tex]=20-1[/tex]

[tex]=19[/tex]

"t" at confidence level 99%, will be:

⇒ [tex]\alpha=1-99 \ percent[/tex]

[tex]=1-0.99[/tex]

[tex]=0.01[/tex]

⇒ [tex]\frac{\alpha}{2}=\frac{0.01}{2}[/tex]

[tex]=0.005[/tex]

⇒ [tex]t\frac{\alpha}{2} \ df=t \ 0.005,19[/tex]

By using the student table, we get

[tex]=2.86 1[/tex]

The margin of error will be:

⇒ [tex]E=\frac{t \alpha}{2,df\times (\frac{s}{\sqrt{n}})}[/tex]

On substituting the estimated values, we get

⇒ [tex]=2.861\times (\frac{6.2}{\sqrt{20}})[/tex]

⇒ [tex]=3.97[/tex]

At 99%, the confidence level will be:

⇒ [tex]\bar{x}-E< \mu <\bar{x}+E[/tex]

⇒ [tex]30-3.97< \mu < 30+3.97[/tex]

⇒ [tex](26.03,33.97)[/tex]

Thus the above is the correct approach.

Nine voltage measurements in a circuit have produced the following values: 12.09, 12.05, 11.94, 11.99, 12.12, 12.05, 12.02, 11.95, 12.14. If the standard deviation for the above data set is 0.07V, determine whether any values can be rejected. (5 Points)

Answers

Answer:

we can not reject any value

Step-by-step explanation: From data we can test the highest and the lowest value to evaluate if one of these values are out of certain confidence Interval

If we established CI = 95 % then α = 5 % and α/2 = 0,025

From data we find the mean of the values

μ₀ = 12,03 and σ = 0,07

From z table we find z score for 0,025 is z(c) = ± 1,96

So limits of our CI are:

12,03 + 1,96 = 13,99

12,03 - 1,96 = 10,07

And all our values are within ( 10,07 , 13,99)

So we can not reject any value

Option D is correct.

Step-by-step explanation:

We are given:

If [tex]i=\sqrt{-1}[/tex] we need to find the value of [tex]i^3[/tex]

Solving:

[tex]i=\sqrt{-1}[/tex]

Taking cube on both sides
