How Do I Do Goldbach’s Conjecture.
Omar measured a summer camp and made a scale drawing. In real life, the sand volleyball court is 9 meters wide. It is 12 centimeters wide in the drawing. What scale did Omar use for the drawing?
Step-by-step explanation:
9 metres = 900cm
Scale = Object length :image length
= 900:12
= 75:1
This means that every 75cm length of the court is represented by 1cm on the drawing paper.
Do employer-sponsored wellness programs work? About 5000 employees at the University of Illinois at Urbana-Champaign volunteered for a study to find out. Researchers randomly assigned 3300 volunteers to a treatment group and the remaining 1534 to a control group. Employees in the treatment group were invited to take paid time off to participate in a wellness program. Those in the control group were not allowed to participate. One measure of the program's effectiveness was employee attrition. In the 2-year period following the start of the study, 356 of the people in the treatment group left their job for any reason, compared to 184 of the people in the control group. Do these results provide convincing evidence at the a= 0. 05 level that offering employees paid time off to participate in a wellness program reduces the proportion who leave their job within 2 years for people similar to the ones in this study?
The research analysis computed do not give supporting evidence that employer-sponsored wellness programs work.
How to analyze the research study?From the information given, the sample proportion for treatment group will be:
= 356/3300 = 0.1078
The sample proportion for the control group will be:
= 184/1534 = 0.1199
The z value is -1.24 and the p value is given as 0.1078. In this case, we fail to reject the null hypothesis.
Therefore, the results do not provide convincing evidence that offering employees paid time off to participate on a wellness program will reduce the proportion of those who leave their job within two years.

The park district is building new bleachers for the softball feild. One row of bleachers will seat 9 people. What is the minimum number of rows needed to seat atleast 150 people?
Answer:
17
Explanation:
First, we observe that 1 row will seat 9 people.
Second, we take 150 and divide that by 9 to get our conversion factor for the amount of bleachers that are needed. Our answer comes out to 16.67, which we can assume that the question is asking for enough to seat all 150 of those people.
So we round up to 17, since 16.67 bleachers simply doesn't exist.
I need help with this problem
Answer:
y = 2x +5
Step-by-step explanation:
f(x) = y means that you want y to be on one side of the equation by itself.
so you need to isolate y.
2y - 4x = 10
first add 4x to both sides of the equation
2y = 4x + 10
then, divide by 2 on both sides to have y by itself
y = 4/2x + 10/2
finally, simplify:
y = 2x + 5
Express in simplest form.
Answer:
x-2/x
Step-by-step explanation:
¨/¨ means over
Answer:
(x-2)/x
Step-by-step explanation:
We can factor the numerator and denominator to see if anything simplifies.
[tex]\frac{(x-2) (x+5)}{x (x+5)}[/tex]
because (x-2)(x+5) = x² +5x-2x-10 = x² + 3x -10 and
x(x+5) = x² +5x
Simplify further
[tex]\frac{x-2}{x}[/tex]
because [(x+5) /(x+5)] = 1
Two points on a circle are points A(-11,7) and B(-9,-3)
1. Determine the equation of a lone containing the center of the circle
2. If the x-coordinate of the center is -5, determine the circle's center: (-5,?)
Answer:
( x + 5 )² + ( y - 3 )² = 52
Step-by-step explanation:
Let find the equation of the line going through A( - 11, 7 ) and B( - 9, - 3 )
m = [tex]\frac{-3-7}{-9+11}[/tex] = - 5
y - 7 = - 5( x + 11 )
y = - 5x - 48
Now, let find the equation of the line passing through midpoint of the segment AB
Coordinates of that midpoint is ( [tex]\frac{-11-9}{2}[/tex] , [tex]\frac{7-3}{2}[/tex] ) = ( - 10 , 2 )
Slope of the perpendicular line is [tex]\frac{1}{5}[/tex] ( opposite reciprocal of ( - 5 )
y - 2 = [tex]\frac{1}{5}[/tex] ( x + 10 )
y = [tex]\frac{1}{5}[/tex] x + 4 ........... (1)
Coordinates of an intersection of two lines (1) and x = - 5 are coordinates of the center of the circle
y = [tex]\frac{1}{5}[/tex] ( - 5 ) + 4 = 3 ⇒ y = 3
O( - 5 , 3 ) is the center
The last!! RADIUS which is OA or OB
r = [tex]\sqrt{(-5+11)^2 +(3-7)^2}[/tex] = √52
( x + 5 )² + ( y - 3 )² = 52

What similarities do scales share with rulers?
Answer:
Both are used to measure some things to some kind of extent.
Step-by-step explanation:
For example Rulers and Scales are used in Geometry to measure length but the extent to which a Scale can measure the length is limited wheareas the for the ruler it is unlimited.
Answer:
They both have a measuring system that looks somewhat like a numberline and they both mesure something. (Also both are referred to as a rular
Step-by-step explanation:
In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale. A device for drawing straight lines is a straight edge or ruler. In common usage, both are referred to as a ruler.

Alex simplified the expression 7+(3x 1. 4)+5+2+(5x1. 4) to find the area of the figure on the grid.
What error did Alex make?
He found the perimeter of the figure instead of the area.
He added the lengths of the lines creating the indentation instead of subtracting them.
He used 5x1. 4 and 3 x 1. 4 as the length of each diagonal line instead of 5 and 3.
He added the five lengths together instead of multiplying them.
The error Alex made while simplifying the expression 7+(3x 1. 4)+5+2+(5x1. 4) is "he found the perimeter of the figure instead of the area".

A runner covers the last straight stretch of a race in 4 s. During that time, he speeds up from 5 m/s to 9 m/s. What is the runner’s acceleration in this part of the race?
Given,
Time taken to cover the last last straight stretch of a race = 4 seconds
He speeds up from 5 m/s to 9 m/s
To find,
The acceleration of the runner.
Solution,
We can simply solve this numerical problem by using the following process.
Here,
Initial velocity (u) = 5 m/s
Final velocity (v) = 9 m/s
Time (t) = 4 seconds
Acceleration (a) = ?
According to the formula of kinematics,
a = (v-u)/t
a = (9-5)/4 [By putting the given values.]
a = 4/4 = 1 m/s²
(We have used SI unit of the acceleration, because all the initial physical quantities are also in SI units.)
Hence, the acceleration is 1 m/s²
