Answer:

The value of the test statistic is of 0.22.

Step-by-step explanation:

Our test statistic is:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the expected mean, [tex]\sigma[/tex] is the standard deviation(square root of the variance) and n is the size of the sample.

A lumber company is making boards that are 2920.0 millimeters tall.

This means that [tex]\mu = 2920[/tex].

A sample of 12 is made, and it is found that they have a mean of 2922.7 millimeters with a variance of 121.00.

This means that [tex]X = 2922.7, n = 12, \sigma = \sqrt{121} = 11[/tex]. So

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]t = \frac{2922.7 - 2922}{\frac{11}{\sqrt{12}}}[/tex]

[tex]t = 0.22[/tex]

The value of the test statistic is of 0.22.

Answer:

  (B)  y = x - 8

Step-by-step explanation:

The slope is found by looking at the change in y divided by the change in x.

The line goes through grid intersections that differ both horizontally and vertically by 1 unit, so ...

  m = rise/run = 1/1 = 1

The y-intercept is where the line crosses the y-axis, at y = -8. The slope-intercept equation is then ...

  y = mx + b . . . . m = slope (1); b = y-intercept (-8)

  y = x - 8 . . . . matches choice B

Answer:

6 ft < L₃ < 30 ft

Step-by-step explanation:

To obtain the answer to the question given above, we must bear in mind that:

The sum of the length of two sides of any triangle is always greater than the 3rd length i.e

L₁ + L₂ > L₃

With the above information in mind, we can obtain the answer to the question given above as follow:

Length 1 (L₁) = 12 feet

Length 2 (L₂) = 18 feet

Length 3 (L₃) =..?

Case 1:

L₁ + L₂ > L₃

12 + 18 > L₃

30 > L₃

L₃ < 30 feet

Case 2:

L₁ + L₃ > L₂

12 + L₃ > 18

Collect like terms

L₃ > 18 – 12

L₃ > 6 feet

Thus,

6 feet < L₃

Combining case 1 and 2,we obtained:

6 ft < L₃ < 30 ft

Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft

Answer:q(x)=0.0625(4)^x

Step-by-step explanation:

If you plug in the equation in desmos and turn it in to a graph it shows the same graph

The value of the exponential equation from the table is y = ( 0.0625 ) ( 4 )ˣ

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the values of x = { 0 , 1 , 2 , 3 }

The values of y = { 0.0625 , 0.25 , 1 , 4 }

So , the exponential equation is a proportional equation as

y = kˣ

y = ( 0.0625 ) ( 4 )ˣ

On simplifying , we get

when x = 1

y = 0.0625 x 4

y = 0.25

when x = 2

y = 0.0625 ( 16 )

y = 1

Hence , the exponential equation is y = ( 0.0625 ) ( 4 )ˣ and the graph is plotted

The nth term of a sequence is 2n + 1

The nth term of a different sequence is 3n  1

Work out the three numbers that are

in both sequences

and

between 20 and 40

Now the three numbers I managed to get are 25, 31 and 37 (as I assumed it meant the output of both of these sequences needs to be the same as well as being in between 20 and 40). For example 2x18+1= 37 as does 3x12+1= 37

The fraction of English teachers who have at least 5 years of experience is [tex]\dfrac{11}{80}[/tex].

We want to calculate the number of teachers that have at least 5 years of experience, therefore, any teacher having experience of 5 years and more will come in this category,

Number of teachers having at least 5 years of experience

= Teacher having 5 to 10 years of experience

  + teachers having more than 10 years of experience

= 9 + 2 = 11

Total number of teachers = 80

[tex]\rm Fraction = \dfrac{\text{Number of teachers having at least 5 years of experience}}{\text{Total number of teachers}}[/tex]

[tex]\rm Fraction = \dfrac{11}{80}[/tex]

Hence, the fraction of English teachers who have at least 5 years of experience is [tex]\dfrac{11}{80}[/tex].

Answer:

? = 45

Step-by-step explanation:

Since the triangles are similar, we can use proportions

20       20+8

------- = -------

?           ? + 18

20         28

------- = -------

?           ? + 18

Using cross products

20 ( ? +18) =  = ? * 28

Distribute

20 ? + 360 = 28 ?

Subtract 20 ? from each side

360 = 8?

Divide each side by 8

360/8 = ?

45 = ?

Step-by-step explanation:

The translation suggests only a change in location and perhaps a change of scale, but the angles remain the same.

So, A is false because ∠D' would be simply 74° like the original.

C is false because ∠F' would be 59° like the original

D is false because D'E' would correspond to DE and not DF.
