Answer:
H0 : the treatment has no effect
Step-by-step explanation:
The test is formulated as hypothesis . Here the test ist that whether the treatment has affected or not . So the null hypothesis can be formulated as
H0 : the treatment has no effect
against the claim
Ha: the treatment has an effect.
The null hypothesis is the test performed and the alternate hypothesis is the claim against the test. Therefore they are opposite of each other.

The operation is defined on the set R of real numbers by ab=ab+a.
Determine whether or not the operation is associative.
Please I need help.
Answer:
ab=ab+a
We need to check the following:
(ab)c=a(bc) or not
LHS
(ab)c=(ab+a)c
=(ab+a)c+(ab+a)
=abc+ac+ab+a
RHS
a(bc)=a(bc+b)
=a(bc+b)+a
=abc+ab+a
as LHS ≠ RHS, the operation is not associative
Step-by-step explanation:
You are looking to save money to start a business. You currently have $500 saved up. We JustWantUrMoney Bank offers a savings account with 12%
interest, compounded annually. How much money would you have after 10 years? Round to the nearest cent, if necessary.
Answer:
You would have $1552.9 after 10 years.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
You currently have $500 saved up.
This means that [tex]P = 500[/tex]
12% interest, compounded annually.
This means that [tex]r = 0.12, n = 1[/tex].
How much money would you have after 10 years?
This is A(10). So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(10) = 500(1 + \frac{0.12}{1})^{10}[/tex]
[tex]A(10) = 1552.9[/tex]
You would have $1552.9 after 10 years.

ΔAED ~ ΔACB
[∠DAE = ∠BAC ( common angle ), [tex]\frac{AE}{AC} = \frac{AD}{AB}[/tex] ( gives a ratio 1:2 ) ]
[tex]\frac{AE}{AC} = \frac{DE}{BC}[/tex]
Since AC = 2AE [ AC = AE + EC, But AE = EC, ∴ AC = AE + AE ]
[tex]\frac{AE}{2AE} = \frac{x + 1}{4x - 6}\\\\\frac{1}{2} = \frac{x + 1}{4x - 6}\\\\\\Cross - multiplying,\\\\4x - 6 = 2 *(x + 1)\\4x - 6 = 2x + 2\\4x - 2x = 2 + 6\\2x = 8\\x = 4[/tex]

factorise 4a-6ab-18ac
Answer:
Step-by-step explanation:
4a-6ab-18ac
=2a(2-3b-9c)
The required factorisation of the given equation is 4a-6ab-18ac = 2a(2 - 3b - 9c).
What is factorisation?In mathematics, factorisation or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.
The given equation is,
4a-6ab-18ac
So factorising each term we have,
4a = 2*2*a
6ab = 2*3*a*b
18ac = 2*3*3*a*c
Thus the equation becomes,
4a-6ab-18ac = 2*2*a - 2*3*a*b - 2*3*3*a*c
taking 2*a common we get,
4a-6ab-18ac = 2a(2 - 3b - 3*3*c)
or, 4a-6ab-18ac = 2a(2 - 3b - 9c)
which is the the required factorisation of the equation.
Thus, the required factorisation of the given equation is 4a-6ab-18ac = 2a(2 - 3b - 9c).

Write an equation for a translation of the parent function y = |x| to translate it 7 units left.
A. y = |x| + 7
B. y = |x + 7|
C. y = |x − 7|
D. y = |x| − 7

Answer:
B. y = |x +7|
Step-by-step explanation:
The translations represented by the answer choices are ...
A. up 7 units
B. left 7 units . . . . the choice we want
C. right 7 units
D. down 7 units
___
In general, the effects of adding things to x and y are summarized by ...
y = f(x -a) +b . . . . . . . . translation right 'a' units, up 'b' units
Translations left or down are accomplished by using negative values for 'a' and/or 'b.

We want translation 7 units left, so a=-7 and b=0
y = |x| ⇒ y = |x -(-7))| or y = |x+7|

amount of sugar solution to be added if the ratio has to be 2:1?
Answer:
15
Step-by-step explanation:
The amountt of sugar and salt would be x and 2x
x+2x=45x
so sugar solution =15 and salt solution =30
ratio =2:1 then sugar =30 salt =15
The amount of sugar solution to be added =30-15=15
