What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.
Given that:
A value or values which, when substituted for a variable in an equation, make the equation true.
x-y/2z = 3
multiply 2z in both sides we get,
2z(x-y)/2z = 3 × 2z
simplify the equation,
x - y = 6z
Add y in both sides we get,
x-y+y = 6z + y
x = 6z
So, the solution of x is 6z.

A primatologist believes that rhesus monkeys possess curiosity. She reasons that, if this is true, then they should prefer novel stimulation to repetitive stimulation. An experiment is conducted in which 12 rhesus monkeys are randomly selected from the university colony and taught to press two bars. Pressing bar 1 always produces the same sound, whereas bar 2 produces a novel sound each time it is pressed. After learning to press the bars, the monkeys are tested for 15 minutes, during which they have free access to both bars. The number of presses on each bar during the 15 minutes is recorded. The resulting data are as follows:What is the alternative hypothesis? In this case, assume a nondirectional hypothesis is appropriate because there is insufficient empirical basis to warrant a directional hypothesis. What is the null hypothesis? Using ? = 0.052 tail, what is your conclusion? What error might you be making by your conclusion in part c?

Mean of difference =[tex]\frac{Sum}{10}=\frac{123}{10}=12.3[/tex]
Standard deviation s =[tex]\sqrt{\frac{(x_i-\bar{x})^2}{n}}=8.93[/tex]
Null Hypothesis : mean of difference scores is 0 : [tex]H_0:\mu=0[/tex]
Alternate Hypothesis : mean of difference scores is different from 0 : [tex]H_a:\mu \neq 0[/tex]
We will use t test for unpaired
[tex]t = \frac{x-\mu}{\sqrt{\frac{s^2}{n-1}}}\\t = \frac{12.3-0}{\sqrt{\frac{8.93^2}{10-1}}}\\t=4.13[/tex]
Level of significance (two tailed) =[tex]\alpha = 0.05[/tex]
Degree of freedom = n-1 = 10-1 =9
Using calculator
The p-value is .002559.
p value < α
So ,we reject null hypothesis
So, It is statistically significant that mean of difference scores is different from 0

Piano lessons with ms bennett cost $30 for 3/4 of an hour what is ms bennetts hourly rate?
Answer:
im not sure but I think its 40
Step-by-step explanation:
bc 3/4 is $30 so 4/4 is an hour then she each would be $10 so 1/4 is 10 then 2/4 is 20 then 3/4 is 30 then 4/4 is 40

How do you divide 34.2 / 7.6 and show your work
Answer:
9/2
Step-by-step explanation:
first you convert the decimal number into a fraction
34.2/7.6= 171/5 over 7.6
then it becomes 171/5 over 38/5
then you reduce the fraction with five(so you cross out the 5's)
now youre left with 171/38
then you reduce the fraction with 19
now you have 9/2
9/2 is your answer

How do you calculate the percentage of a number? ex. 70% of 70
Answer:
Find P percent of X
Find what percent of X is Y
Find X if P percent of it is Y
Step-by-step explanation:
Example: What is 10% of 150?
Convert the problem to an equation using the percentage formula: P% * X = Y
P is 10%, X is 150, so the equation is 10% * 150 = Y
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y
Do the math: 0.10 * 150 = 15
Y = 15
So 10% of 150 is 15
Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15
