i dont know the person up above me is right if not
5 + 2(3 + 2x) = x + 3(x + 1)
Answer:
no solution
Step-by-step explanation:
5 + 2(3 + 2x) = x + 3(x + 1) ← distribute parenthesis on both sides
5 + 6 + 4x = x + 3x + 3 , simplify both sides
11 + 4x = 4x + 3 ( subtract 11 from both sides )
4x = 4x - 8 ( subtract 4x from both sides )
0 = - 8 ← false statement
This indicates the equation has no solution

Which of the following statements is true?
1. 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.
11. In order to use x2 procedures, you must have at least five degrees of
freedom.
III. For a 5 X 6 two-way table, a x2 distribution would be based on 10 degrees
of freedom.
Answer:
I only
Step-by-step explanation:
just trust me bro
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.

What equation represents the relationship between X and y shown in the table below?
Answer: C.
Step-by-step explanation:
Solve the equation for y. Then find the value of y for each value of x. 2x - 7y = 19; X = - 2, 0, 2
PLEASE HELP
Answer:
y=-23/7;y=-19/7;y=-15/7
Step-by-step explanation:
when x is -2 then y is;
2(-2)-7y=19
-4-7y=19
-7y=23 divide both sides by -7
y=-23/7
when x=0 then y is;
2(0)-7y=19
-7y=19
y=-19/7
when x=2 then y is;
2(2)-7y=19
4-7y=19
-7y=15
y=-15/7
What is the distance between the points (2,-6)and(-3,6)
Answer:
Step-by-step explanation:
We can find the distance by using the distance formula.
d= √(x2-x1) ² + (y2-y1)²
For points (x1 = 2, y1 = -6) and ( x2 = -3, y2 = 6)
d= √(-3-2)² + (6 -(-6))², add and subtract what is inside of the parenthesis
d= √(-5)² + ( 12)², square the positive and negative number and get a positive
d= √25 + 144, add the numbers under the square root
d = √169, use the fact that 13*13= 169 to solve the square root
d= 13

Answer:
slope is 11
Step-by-step explanation:
so y = 11x + 62
I used the point slope form to get the y intercept
Hello !
Answer:
[tex]\boxed{ \begin{gathered} \sf \star\ \ y=11x+62 \\ \sf\star\ \ Slope : 11\\\sf \star\ \ y-intercept: 62 \end{gathered}}[/tex]
Step-by-step explanation:
The line pass through the two following points :
[tex]\sf(-5,7)[/tex][tex]\sf (-6,-4)[/tex]The slope-intercept form of a line is of the form [tex]\sf y=mx+b[/tex] where m is the slope and b is the y-intercept.
We're looking for the two coefficients m and b.
Let's replace x and y with their values :
[tex]\begin{cases}\sf 7=-5m+b \\\sf -4=-6m+b\end{cases}[/tex]
We get a system of two equations to solve.
Let's subtract the second line from the first one and solve for m :[tex]\sf 7-(-4)=-5m-(-6m)+b-b\\\iff \sf 7+4=-5m+6m\\\iff \boxed{\sf m=11}[/tex]
Let's substitute 11 for m in the first equation :
[tex]\sf 7=-5\times11+b\\\iff \sf 7=-55+b\\\iff \boxed{\sf b=62}[/tex]
The slope-intercept form of the equation is [tex]\sf y=11x+62[/tex].
The slope is 11.
The y-intercept is 62.

A rectangular box has dimensions 0.045m, 0.034m, 0.01m. Calculate the volume of the box in cm³:
Volume = ___ cm³
Answer:
[tex]15.75 {cm}^{3} [/tex]
Step-by-step explanation:
Convert m to cm,
0.045m =4.5cm
0.034m = 3.5cm
0.01m = 1cm
Volume = 4.5 cm × 3.5 × 1 = 15.75 cm3

A car travels 15 1/10 miles in 1/3 of an hour. What is the average speed, in
miles per hour, of the car?
Step-by-step explanation:
Miles = 15 1/10
Miles = 151/10 miles
Hour = 1/3 hour
Av = 151/10 miles / 1/3 hour
Av = 151/10 × 3 / 1/3 × 3
Av = 453/10 miles / hour
Av = 45,3 mil / h

Answer:
-1
Step-by-step explanation:
From the graph, the y-coordinate of the circled point on the y-axis is the value of f(0). (The y-axis has equation x=0.) That coordinate is -1, so f(0) = -1.
__
From the equation, substituting x=0 makes all of the x-terms disappear, leaving only the constant.
f(0) = -0 +0 -1
f(0) = -1
