Answer:
Two way ANOVA.
Step-by-step explanation:
The two way analysis of Variance statistical analysis technique is used to analyae and determine the variation in sample means. The two way ANOVA is considered when the independent variable is more Than one. Usually two, in the scenario described, the independent variables in the scenario are ; Socioeconomic Status and Gender.
Also.in Analysis of Variance, the groups or factor level of each independent variable must the atleast 3 or more, this factor level serves as the group of the independent variable. Here the factor levels are High, medium and low, which also means that condition for the number of levels is also met.

-15x + 60 ≤ 105 AND 14x + 11 ≤ -31
Choose 1 answer:
A. x ≤ -3
B. x ≥ -3
C. x = -3
D. There are no solutions
E. All values of x are solutions
Answer:
C. x = -3
Step-by-step explanation:
-15x + 60 <= 105
-15x <= 45
-x <= 3
x >= -3
14x + 11 <= -31
14x <= -42
x <= -3
the only solution that is in both solution areas is x = -3.
for all other values of x we violate one of the 2 conditions.

Solve this equation 2n-9<25
Answer:
n < 17
Step-by-step explanation:
2n-9<25
Add 9 to each side
2n-9+9<25+9
2n < 34
Divide each side by 2
2n/2 < 34/2
n < 17
Answer:
n < 17
Step-by-step explanation:
Move the constant to the right -hand side and change its sign
2n<25+9
Then add the numbers
2n < 34
Divide both sides of the inequality by 2
so that would be n<17

Zahraa made 4 pitchers of lemonade. Each pitcher holds ⅓ gallon. How many gallons of lemonade did she make? WHATS THE ANSWER??
Answer:
12 gallons
Step-by-step explanation:
If each pitcher can hold only a third of one of her makings. Think about it. Just pour the glasses in your mind. She fills it up a little bit, and then keeps doing it until 12 are full. or how else to explain it or really explain it at all.

Give the set of four quantum numbers that could represent the last electron added (using the Aufbau principle) to the Cl atom.A) n=3, l=1, ml=1ms=+12B) n=3, l=0, ml=1, ms=−12C) n=3, l=2, ml=1, ms=+12D) n=2, l=1, ml=1, ms=−12E) n=3, l=1, ml=1, ms=−12
Answer:
n=3, l=1, ml=1ms=+1/2
Step-by-step explanation:
The electron configuration of chlorine atom is; [Ne] 3s² 3p⁵.
This means that the last electron is found in a 3pz orbital.
We can see that the principal quantum number is 3. The electron is in a p orbital so l=1, the electron must be found in a 3pz orbital hence ml=1. The electron is found alone in that orbital hence s= 1/2.

a
Step-by-step explanation:
Hey there!
LHS
[tex] = \frac{ \cos(a) }{ \tan(a) } [/tex]
Use tan A = sin A/cosA
[tex] = \cos(a) \times \frac{ \cos(a) }{ \sin(a) } [/tex]
[tex] = \frac{ { \cos(a) }^{2} }{ \sin(a) } [/tex]
Then, Use formula cos²A = 1-sin²A and sinA = √(1-cos²A)
[tex] = \frac{1 - { \sin(a) }^{2} }{ \sqrt{ - { \cos(a) }^{2} } } [/tex]
Proved!

Answer:
(x, y) = (2, 3)
Step-by-step explanation:
The first step is to find the least common multiple of the denominators of each of the equations. If the denominators have no common factors, a reasonable choice is their product. Here, it works to start with the fractions that must be added, then compare the LCM found to the denominator on the right to see if any further factors must be included.
First equation:
LCM = 3×4 = 12
12(2x/3 -y/4) = 12(7/12) . . . . . multiply the equation by 12
8x -3y = 7 . . . . . . . . . simplify
Second equation:
LCM = 4×5 =20
20(3x/4 -2y/5) = 20(3/10) . . . . multiply equation by 20
15x -8y = 6 . . . . . . simplify
Solve by elimination
We can eliminate the y-variable by subtracting 3 times the second equation from 8 times the first:
8(8x -3y) -3(15x -8y) = 8(7) -3(6)
19x = 38 . . . . . simplify
x = 2 . . . . . . . divide by 19
Substituting into the first equation gives ...
8(2) -3y = 7
3y = 9 . . . . . . add 3y-7
y = 3 . . . . . divide by 3
The solution is ...
(x, y) = (2, 3)
_____
There are many ways to solve such a system of equations. Using the LCM to eliminate fractions is one way to start. You can also do the arithmetic with the fractions intact, though most folks don't care to. In addition to the elimination method used here, you can use matrix or graphical methods, substitution, or any of the variations of Cramer's Rule.
Two sides of a triangle measure 8 cm and 15 cm. Which could be the length of the third side?
Answer:
I believe the thirds length could be 17 cm
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
8² + 15² = y²
64 + 225 = y²
y² = 289
√y² = √289
y = 17
In the diagram, Find the value of w
Answer:
-13
Step-by-step explanation:
the angle of ACD is 180-72 = 108 degrees.
simply because every side of a line represents 180 degrees of turning potential (to flip something around on a flat ground is a 180 degree turn). and we know 72 degrees are already "taken" at the other side of the angle.
BC bisects the angle. that means it divided the angle into 2 equal parts.
so the angle between BC and k is 108/2 = 54 degrees.
because j is parallel to k, this angle is the same as the angle between BC and j.
so,
54 = 2w + 80
-26 = 2w
w = -13
Consider the formula for the slope between two coordinate points, m, shown below.
m
92 – 91
I 2
51
Which of the following equations is equivalent to the slope formula?
Answer:
y2 = m(x2 - x1) + y1
Step-by-step explanation:
Given the slope formula :
m = (y2 - y1) / (x2 - x1)
To obtain an equivalent expression :
We cross multiply :
m(x2 - x1) = y2 - y1
Making y2 the subject ;
Add y1 to both sides
m(x2 - x1) + y1 = y2 - y1 + y1
m(x2 - x1) + y1 = y2
y2 = m(x2 - x1) + y1

Keisha's teacher gives her the following information:
• m,n,p,and q are all integers and p= 0 and q=0
•A= m/q and B= n/p
What conclusion can Keisha make?
A: A +B = mp+nq/PQ,so the sum of a rational number and an irrational number is an irrational number.
B: A•B= mp+nq/PQ,so the product of two irrational numbers is an irrational number.
C: A+B= mp + nq/PQ,so the sum of two rational numbers is a rational number.
D: A•B= mp + nq/PQ,so the product of two rational numbers is a rational number.
Answer:
C.
Step-by-step explanation:
Integers are rational numbers.
A + B = m/q + n/p = (mp + nq)/pq
