Answer:
x²-10x+25
Step-by-step explanation:
f(x) = x²
<h3>i) substitute the x-5 into x</h3>f(x-5) = (x-5)²
<h3>ii) using the formula (a-b)² = a²-2ab+b², expand the expression</h3>f(x-5) = (x-5)²
= x²-2(5x)+5²
<h3>iii) calculate the products</h3>f(x-5) = x²-2(5x)+5²
= x²-10x+25

Answer:
Step-by-step explanation:
Let's look at the first two, and hopefully you'll be able to figure the rest out:
1. Answer below
The problem asks us to solve for , so that means we need to get
on one side of the equation by itself. To do so, we will need to divide both sides of the equation by
:
2. Answer below
The problem asks us to solve for , so that means we need to get
on one side of the equation by itself. To do so, we will need to add
to both sides of equation:
Answer:
Type II error occurred
Step-by-step explanation:
It is given that a new shampoo is being tested to determine whether the hair grows faster by using this shampoo.
It is known that hair grow at 0.5 inches per month at average.
The hypothesis are,
Null hypothesis,
Alternate hypothesis,
But it is known that :
Type error occurs when rejecting the null hypothesis when the null hypothesis is true actually.
Type error occurs
when the null hypothesis is actually false.
Now here since the null hypothesis is not been rejected, type error had occurred.
