Answer:
The df values for the A x B interaction are also 3,40
Step-by-step explanation:
The F-value for Factor A has df = 1, 40
The F-value for Factor B has df = 3, 40.
The df values for the A x B interaction are also 3,40
This is because the source of variation between columns has ( c- 1); rc(n-1) degrees of freedom and the source of variation between rows has (r-1); rc(n-1) degrees of freedom and the source of variation of interaction
(between rows and columns) has ( c-1) ( r-1); rc(n-1) degrees of freedom.
Therefore
Factor A: ( c- 1); rc(n-1) = 1,40
Factor B: (r-1); rc(n-1) = 3,40
Interaction : ( c-1) ( r-1); rc(n-1) = 3*1,(40)= 3,40
where c refers to columns , r refers to rows and n refers to the total sample size.
Find the value of x,$3$3)/7:):7):7:
(3x - 5) + 2(5x - 10) + 2(6x + 25) = 540
3x - 5 + 10x - 20 + 12x + 50 = 540
25x + 25 = 540
25x = 540 - 25
25x = 515
x = 515 / 25
x = 20.6
Answer:
[tex]\huge\boxed{\sf x = 20.6}[/tex]
Step-by-step explanation:
We know that the sum of interior angles of a pentagon is:
=> (n-2) *180
Were n is the no. of sides
=> (5-2)*180
=> 3 * 180
=> 540
Hence, The sum of interior angles of a pentagon is 540.
So,
=> 3x - 5 + 6x + 25 + 5x - 10 + 5x - 10 + 6x + 25 = 540
Combining like terms
=> 3x + 6x + 6x + 5x + 5x - 5 + 25 + 25 - 10 - 10 = 540
=> 25x + 25 = 540
=> 25x = 540 - 25
=> 25x = 515
Divide both sides by 25
=> x = 515 / 25
=> x = 20.6

A bag contains 25 red cubes, 15 green cubes, 12 blue cubes, and 8 yellow cubes. The cube is picked at random from the bag. Find each probability as a fraction is lowest terms
Answer:
25/70=red cubes
15/70=green cubes
12/70=blue cubes
8/70=yellow cubes
Step-by-step explanation:
you have to add up all the cubes together and get 70 so you have to see the possibility of getting each cube from the bag.
sorry if you get this wrong
Answer:
Step-by-step explanation: Alright so first add up how many cubes there are in total - 25 + 15 + 12+ 8 = 60. Then, each color cube is its number out of 60. So, for example, for 25 red cubes, it would be 25/60 as a fraction and that’s the probability as a fraction for the red cubes. So:
red = 25/60
green = 15/60
blue = 12/60
yellow = 8/60
then simply the fractions.
25/60 —> 5/12
15/60 —> 1/4
12/60 —> 1/5
8/60 —> 2/15
I hope that helped!

which quadratic equation has 2 and -3 as its roots ?
Answer:
alfa = 2
beeta = -3
product of zeros = 2x-3= -6
sum of zeros = 2+[-3] = -1
POLYNIMIAL = k[x²-[sum]+product]
=k[ x²-[-1] +[-6]]
= k[ x²+1 -6]
= x²-5
hence , the quadratic equation is x²-5

a slice is made parallel to the base of a right rectangular pyramid, as shown.
What is the area of the resulting two-dimensional cross-section?
Enter your answer in the box.
Answer:
27.5cm^2
Step-by-step explanation:
you can cut the triangle to make two right triangles
so 11 is the height and the width is 2.5 since your cutting the triangle in half
so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75
that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5

Now say you invest the $6,500 and the highest interest rate you can find is 2.5% compounded annually, but you would have to leave the investment in the account for a minimum of 5 years. If you decide to wait 5 years to buy the car, how much more money will you have to save to buy a car at the $8,000 price?
Answer:
$648.5
Step-by-step explanation:
Given data
Principal= $6,500
Rate= 2.5%
Time= 5 years
The compound interest formula is given as
A= P(1+r)^t
substitute
A= 6500(1+0.025)^5
A= 6500(1.025)^5
A=6500*1.131
A=$7351.5
After 5 years the money in the account will be $7351.5
Now to buy a car of $8,000
The added amount will be
=$8,000-$7351.5
=$648.5
The stem-and-leaf plot shows the number of broken crayons in each crayon box at a preschool. What is the greatest number of broken crayons in a box? A 7 crayons B 47 crayons c 477 crayons d 1469 crayons
Answer:
47
Step-by-step explanation:
Values on a stem and leaf plot can be obtained by using the key :
Stem | leaf
With each value in the stem representing the first digit and the value in the leaf denoting the second digit.
The highest stem value here is 4 and the highest leaf value is 7.
Hence, the highest number of broken crayon is 47.

Se deposita 4000 soles a una tasa de interés del 0,8% quincenas .¿Que interes producirá en cinco quincenas?
Answer:
Interes= 162,58
Step-by-step explanation:
Dada la siguiente información:
Se deposita 4000 soles a una tasa de interés del 0,8% quincenas
Primero, debemos calcular el valor final de la inversión:
VF= [VP*( 1 + i)^n]
VF= 4.000*(1,008^5)
VF= 4.162,58
Para calcular el interés ganado en 5 quincenas, debemos usar la siguiente formula:
Interes= 4.162,58 - 4.000
Interes= 162,58
Priscilla can make 4 bracelets in 13 minutes. At this rate, how many bracelets can she make in 26 minutes?
Answer:
8

Answer:
Total amount pay for subscription = $228
Step-by-step explanation:
Given:
Down payment of subscription = $24
Number of installments payment = 12
Amount of each installment = $17
Find:
Total amount pay for subscription
Computation:
Assume;
Total amount pay for subscription = P
So,
Total amount pay for subscription = Down payment of subscription + (Number of installments payment)(Amount of each installment)
P = 24 + 12(17)
P = 24 + 204
P = 228
Total amount pay for subscription = $228
