In order to use x2 procedures, each expected cell value of a one- or two-way table must contain a value of at least five. So, option (1) is correct.
What is the Chi-square table?"The Chi-Square distribution table is a table that shows the critical values of the Chi-Square distribution. To use the Chi-Square distribution table, you only need to know two values: The degrees of freedom for the Chi-Square test. The alpha level for the test (common choices are 0.01, 0.05, and 0.10)".
In the given statements,
We need to analyze which statement is true regarding the Chi-square table.
In order for the Chi-square test to be considered trustworthy, each cell of your expected contingency table must have a value of at least five.
Hence we can conclude that in order to use x2 procedures, each expected cell value of a one- or two-way table must contain a value of at least five. So, option (1) is correct.

The perimeter of a rectangle is 56 centimeters. If the length of the rectangle is four centimeters less
than three times its width, what are the dimensions of the rectangle?
Answer:
Let the length be x and the width be y, then
2x + 2y = 56
x + y = 28 . . . (1)
x = 4 + 3y . . . (2)
Putting (2) into (1) gives
4 + 3y + y = 28
4y = 28 - 4 = 24
y = 24/4 = 6
x = 4 + 3(6) = 4 + 18 = 22
Therefore, length is 22 inches and width is 6 inches.

If the condition like the symbol which on the graph
what numeral comes next in the series: 116,113,107,98...?
Step by step have a test tommorow don't know any math need help
Answer:
The next term in the sequence would be 86.
Step-by-step explanation:
116, 113, 107, 98...
The first thing I would do is find the difference between all consecutive terms.
[tex]116-113=3\\113-107=6\\107-98=9[/tex]
The difference increases by 3 for every consecutive term, meaning each consecutive term is decreased by 3 more than the last.
Knowing that pattern, the next term in the sequence must have a difference of 12:
[tex]9+3=12\\98-12=86[/tex]
The next term in the sequence would be 86.

Objective function: z=9x+7y
Constraints:
x ≥0, y ≥0
x+y ≥1
2x+4y ≤16
4x+2y ≤16
Find the objective function, the maximum value of Z, and where the maximum value occurs.
Answer:
The maximum value of z is 43.2 when x=2.7 and y=2.7 . The minimum value of f is 7 when x=0 and y=1
Step-by-step explanation:
f(x,y): z = 9x + 7y ... (1)
from the graphing we get the vertices of the constraint region formed are:
(0,4) (0,1) (1,0) (4,0) (2.7,2.7) ... plug in (1)
at (0,4): z = 28
at (0,1): z = 7
at (1,0): z = 9
at (4,0): z = 36
at (2.7,2.7): z = 43.2
The maximum value of z is 43.2 when x=2.7 and y=2.7 . The minimum value of z is 7 when x=0 and y=1

How did the temperature change? First, it decreased by 60%, and then it increased by 80%
Answer:
1.08 times (108% of) the starting value.
Step-by-step explanation:
Let's say the original temperature was 100. (if it wasn't, you just have to scale it accordingly: was it 50, you take half of the result, and so on). After the first "step" the temperature dropped by 60%. And 60% of 100 is conveniently 60. At this point, it increased by 80%. Now, 80% of 60 is 48. (every 10 units you take 8, so 8x6). At this point we increase 60 by this value to get 108. We started at a temperature of 100, so the new temperature is 108/100 = 1.08 times the original one - or in percentage, 108%

The relationship between the Celsius (C) and Fahrenheit (F) scales for measuring temperature can be represented by a linear function. A temperature of 50 °F corresponds to 10 °C, and a temperature of 212 °F corresponds to 100 °C.
Which statement is the best interpretation of the slope of the graph of this function?
Question 1 options:
For each change of one degree in the Fahrenheit scale, there is a change of 59
5
9
degree in the Celsius scale.
A temperature of 0 °F corresponds to -17.78 °C.
A temperature of 0 °C corresponds to 32 °F.
For each change of one degree in the Fahrenheit scale, there is a change of 95
9
5
degree in the Celsius scale.
The slope is 9/5, this means that for each change in degree in the Celsius scale there is a change of 9/5 degree in the Fahrenheit scale.
The y intercept is 32, this means that a temperature of 0 °C corresponds to 32 °F
A linear equation is given by:
y = mx + b
where y, x are variables, m is the slope of the graph and b is the y intercept.
Let F represent the temperature in Fahrenheit and C represent the temperature in Celsius.
50 °F corresponds to 10 °C it is given as (10, 50), while 212 °F corresponds to 100 °C, it is given as (100, 212). Hence:
[tex]F-F_1=\frac{F_2-F_1}{C_2-C_1} (C-C_1)\\\\\\F-50=\frac{212-50}{100-10}(C-10) \\\\\\F-50=\frac{9}{5}(C-10) \\\\\\F=\frac{9}{5}C+32[/tex]
The slope is 9/5, this means that for each change in degree in the Celsius scale there is a change of 9/5 degree in the Fahrenheit scale.
The y intercept is 32, this means that a temperature of 0 °C corresponds to 32 °F
