Answer:

3. The number of copies he made is 1.25 standard deviations more than the mean number of copies made by teachers.

Step-by-step explanation:

In statistics, a z-score is measurement that describes a value's relationship to the mean and allows us to compare the value and the mean. It tells us how many standard deviations above or below the population mean.

Mr. Thomas has a z-score of 1.25.

He made 782 copies last week. The statistic this is being compared to is the mean of 550 copies by teachers per week at Lamley High School.

Therefore, the best interpretation is Mr. Thomas made 1.25 standard deviations more than the mean number of copies. The correct answer is choice 3.

Let's make sure the other choices are incorrect.

Answer:

[tex]r=\dfrac{PV}{nT}[/tex]

Step-by-step explanation:

The given equation is :

[tex]PV=nrT[/tex]

Where

P is pressure

V is volume

n is no of moles

r is Gas constant

T is temperature

We need to solve the above equation for r.

Dividing both sides of the above equation by (nT). So,

[tex]\dfrac{PV}{nT}=\dfrac{nrT}{nT}\\\\r=\dfrac{PV}{nT}[/tex]

So, the value of r is equal to [tex]\dfrac{PV}{nT}[/tex].

Answer:

  $4717.30

Step-by-step explanation:

Assuming the interest is capitalized only at the start of repayment, the accrued interest is ...

  I = Prt

  I = ($29,300)(0.0322)(4 +1) = $4717.30

The accrued interest is $4717.30.

Answer:

1335.7

Step-by-step explanation:

f(5)= 9e^x

Substitute x for 5 and solve

The value of the equation f ( x ) = 9eˣ , when x = 5 is  1335.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be f ( x ) = 9eˣ

The equation is an exponential form , and the value of x is substituted in the equation

When the value of x is 5

The value of e = 2.7182

x = 5

So , substituting the value of x in f ( x ) , we get

f ( x ) = 9eˣ

f ( 5 ) = 9 x e⁵

Now , e⁵ = 148.4131

And ,

The equation f ( 5 ) = 9 x 148.4131

                                = 1335.718

                                ≈ 1335.7

Hence , the value of the equation f ( x ) = 9eˣ , when x = 5 is  1335.7

Answer:

Angle of elevation: 68.2°, distance from Mr. clanton to the eagle: 32.3m.

Step-by-step explanation:

I can't draw the diagram , but will try to explain:

the diagram is a right angled triangle, with the opposite as the rig, the adjacent as the distance between mr. clinton and the base of the rig, and the hypotenuse as x.

∅ is the angle of elevation from clinton to the eagle.

Using SOH CAH TOA,

Tan∅ =30÷12

tan∅ =2.5.

∅ =tan^-1( tan raised to power -1 )

∅ =tan^-1(2.5)

∅ = 68.19859051≅68.2 to 3s.f.

To get the distance between mr. clinton and the eagle:

Using SOH CAH TOA;

Cos68.2 =12/x   cross multiplying....

x*cos68.2 =12

∴ x = 12 ÷ cos 68.2

= 12 ÷ 0.3713678356

= 32.31297611≅32.3 to 3s.f.

Answer:

Step-by-step explanationBy definition we have that the area of a regular octagon is:

A = 4.83L ^ 2

Where, L is the length of the octagon side.

the similarity ratio = the area ratio.

We have then:

similarity ratio = (50) / (18) = 25/9.

the ratio of the perimeters

A1 = 4.83L1 ^ 2

L1 ^ 2 = A1 / 4.83

L2 ^ 2 = A2 / 4.83

L1 ^ 2 / L2 ^ 2 = A1 / A2 = 25/9

L1 / L2 = 5/3

The perimeter is:

P1 = 8L1

P2 = 8L2

P1 / P2 = 8L1 / 8L2 = L1 / L2 = 5/3

answer:

similarity ratio:

25: 9

the ratio of the perimeters:

5: 3

Answer:

y=(x-4)²-4

Step-by-step explanation:

Our x-intercepts are (2,0) and (6,0) so we can state them as expressions and expand:

(x-2)(x-6)=0 [Remember that (2,0) is the solution to x-2=0 just as (6,0) is the solution to x-6=0]

x²-8x+12=0 (Standard Form)

x²-8x+12+4=0+4 (Completing the square)

x²-8x+16=4

(x-4)²=4

(x-4)²-4=0

Therefore, our equation for the graph in vertex form is y=(x-4)²-4

Answer: 5 1/2

Step-by-step explanation:

You keep your whole number which is five, then you see that the other 5 is in the tenths place in the decimal (5.5) so you put 5 over 10 and combine the fraction (5/10) with the whole number (5) and that is 5 5/10. But you see that it is not simplified so you simplify and get 5 1/2. I hope this helps :)

Answer:

  A)  26°

Step-by-step explanation:

The angle x decreases at a rate that is 12 times the rate of increase of angle y.

  x = 360 -12y

We want x = 2y, so ...

  2y = 360 -12y

  14y = 360

  y = 360/14 ≈ 25.71 ≈ 26

The integer angle closest to y is 26°.
