Answer:
B. x ≈ 13/8
Step-by-step explanation:
We assume that one iteration consists of determining the midpoint of the interval known to contain the root.
The graph shows the functions intersect between x=1 and x=2, hence our first guess is x = 3/2.
Evaluation of the difference between the left side expression and the right side expression for x = 3/2 shows that difference to be negative, so we can narrow the interval to (3/2, 2). Our 2nd guess is the midpoint of this interval, so is x = 7/4.
Evaluation of the difference between the left side expression and the right side expression for x = 3/4 shows that difference to be positive, so we can narrow the interval to (3/2, 7/4). Our 3rd guess is the midpoint of this interval, so is x = 13/8.
_____
The sign of the difference at this value of x is still negative, so the next guess would be 27/16. It is a little hard to tell what the question means by "3 iterations." Evaluating the function for x=13/8 will be the third evaluation, so the determination that x=27/16 will be the next guess might be considered to be the result of the 3rd iteration.
Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.
μ =2000, σ =100
We have to find z score for income $2100 i.e x=2100
Z = 
= 
Z = 100/100
Z = 1
The z score for income $2100 is 1

Answer:
terms, 2x, 3y , x and 7,
like terms, 2x, 3y, x and 7
Coefficient. 2 is the coefficient of 2x and 3 is the coefficient of 2y 1 is the coefficient of x
Constant. 7
Step-by-step explanation:
Given:
Terms are the number of parts in the expression.
there are four terms 2x, 3y , x and 7,
Like terms are the part of the polynomials. 2x, 3y and x are like terms because they both have an x attached. 7 is like terms because they have nothing attached.
The number that are attached to variable is called Coefficient.
So In the term 2x the number 2 is a coefficient because it is attached to x similarly 3y the number 3 is a coefficient because it is attached to y
and in the term x the number 1 is a coefficient.
Constant are the numbers that are not attached to any variable and it is not change. Such as 7 is the constant term.
