In an analysis of variance problems,there are 3 treatments and 10 observations per treatment,the sum of squares for the error is 399.6.What is the mean square for the error for this situation
Answer:
The answer is "14.8".
Step-by-step explanation:
[tex]n = 30\\\\ k = 3\\\\dfE = n-k \\\\[/tex]
[tex]= 30-3 \\\\= 27[/tex]
[tex]SSE = 399.6 \\\\MSE = \frac{SSE}{dfE}[/tex]
[tex]= \frac{399.6}{27} \\\\ = 14.8[/tex]
Which is equivalent to 80 1/4x
Answer:
20x
Step-by-step explanation:
[tex]\frac{80}{4}=\frac{20}{1}=20[/tex]

53.9 as a mixed number
Answer:
The fraction 53 9 is equivalent to 5 8 9.
Step-by-step explanation:
This fraction is a improper fraction once the absolute value of the top number or numerator (53) is greater than the absolute value of the bottom number or denomintor (9). So, the equivalent fraction is a mixed number which is made up of a whole number (5) and a proper fraction ( 8 9 ).
[tex]53 \frac{9}{10}[/tex]
53.9 can be split into 53 and .9
53 is the whole number
.9 is in the tenths place so it can be written out of 10: [tex]\frac{9}{10}[/tex]
It doesn't need to be simplified leaving us with 53 [tex]\frac{9}{10}[/tex]
hELLPPpPpPpPppppp its like not that hard but im having a mental block rn and i literally cant
i know this isnt true but WHY pleasse explain why its wrong and show the work!!
Answer:
The reason why it isnt true is because you cannot combine exponents that have different bases.
Step-by-step explanation:
So, with the problem shown below, it is [tex]3^5*2^4[/tex]
This cannot be multiplied.
To get [tex]6^9[/tex], you would need 6^4*6^5
So basically, its like ths:
If two exponents have to same base, they can be added together. THis adds the exponents, but leaves the bases the same.
If two exponents have different bases, they cannot be added together. You would have to distrubute both the numbers exponents then multiply them together.
For instance, with [tex]3^5*2^4[/tex], you would have to make it 243+16
This would equal 259.
As we can see, [tex]6^9[/tex] is over 10 million, much bigger than this.
I hope this makes sense and helps!
Someone please help!!! I also posted other questions if you want more points!!!
Answer:
3/2
Step-by-step explanation:
3y + 2x = 12
subtract 2x from both sides
3y = -2x + 12
Divide both sides by
3
y = (-2/3)x + 4
Slope = -2/3
----------------------
Slopes of perpendicular lines are negative reciprocals
The negative reciprocal of -2/3 is
3/2

Step-by-step explanation:
A population of mice is increasing exponentially. On Monday there were 120 mice. One month later there were 132 mice. Write a function to model this situation. Determine the percent increase of the population of mice each month.
Answer:
[tex]y =120*1.1^x[/tex]
[tex]r = 10\%[/tex] --- Percentage increase
Step-by-step explanation:
Given
Let
[tex]x \to months[/tex]
[tex]y \to mice[/tex]
So, we have:
[tex](x_1,y_1) = (0,120)[/tex] --- Monday
[tex](x_2,y_2) = (1,132)[/tex] --- One month later
Required
The function
The function is represented as:
[tex]y = ab^x[/tex]
In [tex](x_1,y_1) = (0,120)[/tex], we have:
[tex]120 =a * 1[/tex]
[tex]120 =a[/tex]
Rewrite as:
[tex]a = 120[/tex]
In [tex](x_2,y_2) = (1,132)[/tex], we have:
[tex]132 = a * b^1[/tex]
[tex]132 = a * b[/tex]
Substitute [tex]a = 120[/tex]
[tex]132 = 120 * b[/tex]
Solve for b
[tex]b = \frac{132}{120}[/tex]
[tex]b = 1.1[/tex]
Recall that:
[tex]y = ab^x[/tex]
Hence, the function is:
[tex]y =120*1.1^x[/tex]
To get the monthly percentage increase (r), we have:
[tex]y = a(1 + r)^x[/tex]
Compare to: [tex]y = ab^x[/tex]
So:
[tex]1+r =b[/tex]
Make r the subject
[tex]r = b-1[/tex]
[tex]r = 1.1-1[/tex]
[tex]r = 0.1[/tex]
Express as percentage
[tex]r = 0.1*100\%[/tex]
[tex]r = 10\%[/tex]
cual es el perimetro de 12 cm de ancho y 22 de largo
es para hoy
Answer:
Perimeter of figure = 68 centimeter
Step-by-step explanation:
Given information:
Width of side = 12 centimeter
Length of side = 22 centimeter
Find:
Perimeter of figure
Computation:
Perimeter of rectangle = 2[l + b]
Perimeter of figure = 2[Width of side + Length of side ]
Perimeter of figure = 2[12 + 22]
Perimeter of figure = 2[34]
Perimeter of figure = 68 centimeter
What’s the
mean
Median
Mode
To this question up there
Answer:
mean: 4.5 (1dp)
median: 4
mode: 6
Step-by-step explanation:
mean:
0 + 1 + 1 + 2 + 2 + 2 + 2 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 6 + 6 + 6 + 6 + 7 + 8 + 8 + 9 + 10 = 113
113 divided by 25 = 4.52, or just 4.5 (rounded to one decimal place
median:
(middle) = 4
mode:
(most occurring) = 6

f(x) = { x + 7 and g(x) = -x + 7
What transformation occurs from function f to function g?
=====================================================
Explanation:
We have these two given functions
f(x) = x+7g(x) = -x+7The change is that the x has been replaced with -x
We can say
f(x) = x+7
f(-x) = -x+7 ... replace each x with -x
g(x) = f(-x)
g(x) = -x+7
When we replace x with -x, we're flipping the x inputs from positive to negative, and vice versa. This visually will reflect the line over the vertical y axis. A point like (1,8) on f(x) reflects over to (-1,8) on g(x).
As another example, the point (-5,2) on f(x) reflects over the y axis to arrive at (5,2) on the g(x) function.
