A school collected some information about the experience of its teachers. Here is what they found: What fraction of English teachers have at least 5 years of experience?
The fraction of English teachers who have at least 5 years of experience is [tex]\dfrac{11}{80}[/tex].
Number of teachers having at least 5 years of experienceWe 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
Fraction of English teachers have at least 5 years of experience[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:
(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

The table contains some point on the graph of an exponential function X x 0 1 2 3 why is 0.0625 0.25 1 4
Based on the table which function represents the same relationship
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
What are the laws of exponents?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 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.
Point D is located at (-4,4), Point E is located at (4,4), Point F is located at (4,2) and Point G is located at (-4,2). What is the perimeter of this object? What is the area of this object? Who ever answers fastest and is correct will get brainliest.

Describe the possible lengths of the third side of the triangle given that the lengths of the other two sides are 12 feet and 18 feet.
I attached the picture too.
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

Which functions graph is a translation of the graph of f(x)=x shifted 5 units to the right
a. g(x)=5x
b. g(x)=x-5
c.g(x)=x+5
d. g(x)=-5x
The function of the graph of a translation of the graph of f(x) = x shifted 5 units to the right is g(x) = x - 5, so option B is correct, the graph is also attached below.
What is function?When a function from one set to the other is utilized, every element of X receives precisely one element of Y. The function's domain and co-domain are collective terms used to refer to the sets X and Y, respectively.
Given:
f(x) = x, shifted 5 units to the right
A translation is a change in the graph's direction, either horizontally or vertically, parallel to the -axis.
Here, the translation is of 5 units,
Thus, the new function will be,
g(x) = x - 5

A factor is a number that can be evenly divided into other whole number without having a remainder left over.
A lumber company is making boards that are 2920.0 millimeters tall. If the boards are too long they must be trimmed, and if the boards are too short they cannot be used. 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. A level of significance of 0.05 will be used to determine if the boards are either too long or too short. Assume the population distribution is approximately normal. Find the value of the test statistic. Round your answer to three decimal places.
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.
A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72. How much was the bill before applying the voucher discount code.
Answer:
£91.80
Step-by-step explanation:
You first have to think, what is 15% of £36.72?
To do this, simply divide 100 by 3672, as we converted £36.72 to pence.
So 3672/100= 36.72. Then we multiply it by 15, which gives us 550.8
We then convert it back to pounds.
After you work that out you will get an answer of £55.08
We then add £55.08 to £36.72 and that will give us the answer, which is...
£91.80
OR
A quicker way is 15/100 of £36.72. Add the answer to £36.72= £91.80
