Complete Question
A measurement template with a historical value of 25.500 mm is measured 27 times and a mean value of 25.301 mm is recorded. What is the percent bias when the tolerance is +/- 0.3?
Answer:
The percent bias is [tex]B = 33.167 \%[/tex]
Step-by-step explanation:
From the question we are told that
The historical value is [tex]S = 25.00 \ mm[/tex]
The number of times it is measured is n = 7
The mean value is [tex]\= x = \frac{\sum x_i }{n} = 25.301 \ mm[/tex]
The tolerance is [tex]t =\pm 0.3 = 0.3 - (-0.3) = 0.6[/tex]
Generally the percent bias is mathematically represented as
[tex]B = 100 * \frac{\= x - \tau }{ t}[/tex]
=> [tex]B = 100 * \frac{25.301 - 25.5000 }{0.6}[/tex]
=> [tex]B = 33.167 \%[/tex]

that is 15 inches tall. If the Statue of Liberty is 305
feet tall, what is the scale of the model?
Answer: 1525
Step-by-step explanation:
Explanation:
One way we can do this is to divide the hight of the Statue by the model height:
305ft 1525ft
20in = 1 in
And so for every inch of the model, it represents 15.25 feet.

If you ask the first 50 females who enter a restaurant to complete a survey about their experience, who is the sample?
Answer:
the first girl
Step-by-step explanation:
because the first girl to take the survey is a sample but the rest that follows are just extras(can i get brainliest pls)
The sample in this scenario would be the first 50 females who enter the restaurant and are asked to complete a survey about their experience. These 50 females form a subset of the entire population of females entering the restaurant during that specific period.
A sample is a smaller group selected from a larger population for the purpose of gathering information or conducting research. It is often used in situations where it is impractical or impossible to survey the entire population. By surveying this sample of 50 females, the restaurant may gain insights into the experiences and opinions of their female customers.
It's important to note that the sample should ideally be randomly selected to ensure that it represents the population fairly. In this case, if the first 50 females entering the restaurant are chosen randomly, they can provide valuable feedback on their overall experience, which may help the restaurant make improvements or gain valuable insights into their customer base.

Solve |3x - 2| = |x + 1|
A) x = 3/2 or x= 1/4
B) x= 1/4
C) No solutions
D) x = 3 or x = -4
Answer:
A) x = 3/2 or x= 1/4
Step-by-step explanation:
Solve for x
|3x − 2| = |x + 1|
Rewrite the absolute value equation as four equations without absolute value bars.
3x − 2 = x + 1
3x − 2 = − (x + 1)
− (3x − 2) = x + 1
− (3x − 2) = − (x + 1)
After simplifying, there are only two unique equations to be solved.
3x − 2 = x + 1
3x − 2 = − (x + 1)
Solve 3x − 2 = x + 1 for x.
Move all terms containing x to the left side of the equation.
2x − 2 = 1
Move all terms not containing x to the right side of the equation.
2x = 3
Divide each term by 2 and simplify.

x = ------

Solve 3x − 2 = − (x + 1) for x.
Simplify − (x + 1).
3x − 2 = −x − 1
Move all terms containing x to the left side of the equation.
4x − 2 = −1
Move all terms not containing x to the right side of the equation.
4x = 1
Divide each term by 4 and simplify.

Jayson reads the first 48 pages of a 480-page book in 3 days. Marcus reads the first 50 pages of a 400-page book in 4 days. Nina reads the first 120 pages of a 600-page book in 5 days. If they continue to read at these rates, who will finish first?
Answer:
Nina will finish first.
Step-by-step explanation:
Let's calculate how many pages each person reads in one day:
Jayson ⇒ 48 pages / 3 days = 16 pages/dayMarcus ⇒ 50 pages / 4 days = 12.5 pages/dayNina ⇒ 120 pages / 5 days = 24 pages/dayThen we divide the number of pages of each book by reading speed of the respective person:
Jayson ⇒ 480 pages ÷ 16 pages/day = 30 days Marcus ⇒ 400 pages ÷ 12.5 pages/day = 32 days Nina ⇒ 600 pages ÷ 24 pages/day = 25 daysThus Nina will take the shortest time finishing her book.

What is the greatest common factor of 10, 20, and 50?
Answer:
10
Step-by-step explanation:
first you need to find the prime factors of the three numbers
ex:
prime factor of 18= [tex]2*3*3[/tex]
prime of 24=[tex]2*2*2*3[/tex]
there is one 2 and one 3 in common
greatest common multiple 2*3=6
so the greatest common multiple is ten because it is the only one that can divide between all three evenly.
[tex]10=10/10=1\\20=20/10=2\\50=50/10=5[/tex]
so 10 is your answer

The line passing through the points (-2,12) and (3,-23) intersects the line passing through which of these pairs of points ? Select three that apply .
Answer:
The equation of the straight line passing through the points
7x +y +2=0
Step-by-step explanation:
Step(i):-
Given points are ( -2 , 12 ) and ( 3, -23)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-23-12}{3-(-2)} = \frac{-35}{5} =-7[/tex]
Step(ii):-
The equation of the straight line passing through the points
[tex]y - y_{1} = m( x-x_{1} )[/tex]
[tex]y - 12 = -7( x-(-2) )[/tex]
y - 12 = - 7x -14
7 x + y - 12 + 14 =0
7x +y +2=0
