it's easy it's called Two-way tables please help
Answer: The filled out table is shown below in the attached image
===========================================================
Explanation:
The letters A through J are one way to fill out the table. Though there are other possible orders.
Start at letter A, which is from the fact we have 40 people total
Then move to letter B. This is the total number who like pasta (26)
We have C = A-B = 40-26 = 14 people who don't like pasta
--------------
Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.
F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.
Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.
----------------
So we have these values
A = 40B = 26C = 14D = 21E = 19F = 4G = 17H = 9 J = 10What is 2.1 with 1repeating as a mixed number

A rectangle’s base is 6 cm longer than its height. The rectangle’s area is 135 cm2. Find this rectangle’s dimensions. You must include units with your answers
Area of a rectangle = length x height
Area = 135
Height = X
Lenght = x +6
135 = x * x+6
Simplify:
135 = x^2 +6x
Subtract 135 from both sides:
x^2 + 6x - 135 = 0
Solve:
2 numbers when added need to equal 6 and when multiplied equal -135
x = 9 and x = -15
The height can't be a negative number so the height is 9
Length = 9 +6 = 15
Height = 9cm, Length = 15 cm
On one map of a town , the scale from the town to the map is 12mi to 3 cm. the school is 2.5cm from the grocery store on this map. on a different map of the same town ,the scale from the town to the map is 12mi to 2cm .the school is 1.5cm from the library on that map. is the grocery store or library closer to the school?
Answer:
Step-by-step explanation:
Grocery Store
12 mi / 3 cm = x / 2.5 cm Cross multiply
12 * 2.5 = 3 * x Multiply
30 = 3x Divide by 3
30/3 = x
x = 10 miles
Library
12 mi / 2 cm = x / 1.5 Cross multiply
12 * 1.5 = 2x
18 = 2x Divide by 2
18/2 = x
9 miles
The library is closer than the grocery store.

There are 360 7the grade students at eisenhower middle school. One fourth of the students went to clermonth elementary. Of the rest half went to central elementary and the others came from other schools. How many students came from central elementary?
Answer:
Step-by-step explanation:
1/4x + 1/2x + 1/4x = 360
4(2/4x + 1/2x = 360)
2x + 2x = 1440
4x = 1440
x = 360
1/4(360)= 90 Clermonth
1/2(360)= 180 Central
1/4(360)= 90 other schools

Hey There!! ~
The answer to this is: the upper bound for the length is [tex]21.5cm.[/tex] Lower and Upper Bounds
The lower bound is the smallest value that will round up to the approximate value.
The upper bound is the smallest value that will round up to the next approximate value.
Ex:- a mass of 70 kg, rounded to the nearest 10 kg, The upper bound is 75 kg, because 75 kg is the smallest mass that would round up to 80kg.
Here , A length is measured as 21cm correct to 2 significant figures. We need to find what is the upper bound for the length . let's find out:
As discussed above , upper bound for any number will be the smallest value in decimals which will round up to next integer value . So , for 21 :
⇒ [tex]21.5cm.[/tex]
21.5 cm on rounding off will give 22 cm . So , the upper bound for the length is [tex]21.5cm.[/tex]

A sailor entered a race and made a round trip of 213.709 miles. What is 213.709 rounded to the nearest hundredth?
Which of the following statements explains how you should find 213.709?
A. Since the digit in the hundredths place is less than five, keep the digit in the hundredths place. Then drop the digits on the right.
B. Since the digit in the hundredths place is less than five, keep the digit in the tenths place. Then drop the digit in the hundredths and thousandths places.
C. Since the digit in the thousandths place is greater than or equal to five, increase the digit in the hundredths place by one. Then drop the digit in the thousandths place.
D. Since the digit the hundredths place is less than five, leave the digit in the hundredths place and drop all the numbers on the right.
Answer:
C
Step-by-step explanation:
There was this saying they told me for rounding things. 5 or more, let it soar. 4 or less, let it rest. 9 is greater than or equal to 5, meaning that the digit in the hundredths place will increase by one.
1. Explain how measurements taken by standard rulers and scales are limited,
2. Include two to three examples to demonstrate these limitations. Include at least one limitation of using
a ruler and at least one limitation of using a scale,
3. Make sure to write your answer using five to ten complete sentences,
Answer:
Please find the answer in the explanation
Step-by-step explanation:
RULER
measurements taken by ruler can be limited due to absolute errors, zero error and uncertainties.
1.) If the end of the ruler is worn out giving rise to a zero error
2.) The calibration of the ruler may give rise to another systematic error if the makings are incorrect.
3.) If the object to be measured is not on the same level as graduated surface of the ruler, the angle at which the scale is viewed will affect the result. This is known as parallax error.
SCALE
Systematic error can occur in a scale when the scale is wrongly calibrated.
Also, reading a scale from different angles introduces a variable parallax error.
random uncertainty could be a parallax error caused by taking readings from different angles. This can be reduced by the use of a mirror behind the scale and viewing normally.
A rope 5 meters long was cut into 7 equal parts. What is the length of each part?
Answer:
5/7 meters
Step-by-step explanation:
Take the 5 meters and divide into 7 parts
5/7 = 5/7 meters
To find the length of each part, we can divide.
5 / 7 = 0.714...
We can just keep it as a fraction.
The answer is 5/7m

In the Atlanta metropolitan area, 723 new cases of invasive cancer of the cervix occurred among white women between 1975 and 1984, inclusive. An estimated 620,000 white women lived in this area on average during this time period. What is the average annual incidence rate of invasive cervical cancer in this population?
Answer:
1.166 per 1000 of population
Step-by-step explanation:
Given the following :
Newly recorded cases of invasive cervical cancer = 723
Period of time = 1975 - 1984 ( inclusive)
Estimated average Population of white women in the area at the time = 620,000
Average annual. Incidence rate invasive of cervical cancer in the population.
Incidence rate = (new cases / total population) × 10^n
Incidence rate = (723/620000) × 10^n
= 0.0011661
= 1.166 per 1000 of population

Answer:
[tex]A=\frac{Y+8}{B}[/tex]
Step-by-step explanation:
So we have:
[tex]Y=AB-8\\[/tex]
First, add 8 to both sides. The right will cancel:
[tex]Y+8=AB[/tex]
Now, notice that A is multiplied to B. So, the isolate A, divide both sides by B. The right will cancel:
[tex]A=\frac{Y+8}{B}[/tex]

f(x)=40+4x+x^2 (e) What is the slope of the chord connecting the points (5, f (5)) and (5 + ∆x, f (5 + ∆x)), when ∆x = 5? Really confused on how to do this and what it means
Answer:
19
Step-by-step explanation:
So we have the function:
[tex]f(x)=40+4x+x^2[/tex]
And we want to find the slope of the chord that connects the points (5,f(5)) and (5+Δx, f(5+Δx)).
So first, find the two points.
1) (5,f(5))
Substitute in 5 for x:
[tex]f(x)=40+4x+x^2\\f(5)=40+4(5)+(5)^2[/tex]
Square and multiply:
[tex]f(5)=40+20+25[/tex]
Add:
[tex]f(5)=85[/tex]
So, our first point is (5,85)
2) (5+Δx, f(5+Δx))
Remove the Δx by substituting it with 5. Thus:
[tex](5+\Delta x,f(5+\Delta x))=(5+5,f(5+5))=(10,f(10))[/tex]
Now, substitute in 10 for x. Thus:
[tex]f(10)=40+4(10)+(10)^2[/tex]
Square and multiply:
[tex]f(10)=40+40+100[/tex]
Add:
[tex]f(10)=180[/tex]
So our second point is (10,180).
Now, just find the slope between (5,85) and (10,180) using the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (5,85) be x₁ and y₁ and let (10,180) be x₂ and y₂. Substitute:
[tex]m=\frac{180-85}{10-5}[/tex]
Subtract:
[tex]m=\frac{95}{5}[/tex]
Divide:
[tex]m=19[/tex]
So, the slope that connects the chord is 19.
And we are done :)
Can anyone answer this for me and explain? I’ll give a thanks.
Answer:
86°
Step-by-step explanation:
If you draw a line segment AC, it forms the rest of right triangle ACB with the right angle at C. Then angle BAC is the complement of the given angle:
∠BAC = 90° -47° = 43°
The inscribed angle BAC intercepts arc BC, so the arc measure will be double the angle measure.
arc BC = 2·43° = 86°
__
Another way to get there is to realize that arc BCA is 180°, because AB is a diameter. As above, arc AC will be double the measure of inscribed angle ABC, so arc AC has measure 94°.
arc BC = arc ACB - arc AC
arc BC = 180° -94°
arc BC = 86°
