The solution to the equation is (b) there is no solution.
<h3>How to solve the rational equation?</h3>
The equation is given as:
Factorize the quadratic numerator
Multiply through by (x - 1)(x - 2)
2x(x - 2) - (2x -5) = -3(x - 1)
Expand
2x² - 4x - 2x + 5 = -3x + 3
Collect like terms
2x² - 4x - 2x + 3x + 5 - 3 = 0
Evaluate the like terms
2x² - 3x + 2 = 0
Using a graphical tool, the above equation has no real solution
Hence, the solution is (b) there is no solution.

An exponent tells you how many multiples there are of a number.
1a. (0.6)^2 = (0.6)*(0.6) = 3.6
1b. 4^2 = 4*4 = 16
An exponent of 1 is just one of the number, an exponent of zero is always equal to 1.
2a. (0.3)^1 = 0.3
if there's parenthesis, you must multiply all within it by itself.
3a. (1/10)^2 = 1^2/10^2 = 1/100
3b. (2/3)^2 = 2^2/3^2 = 4/9
hope this helps. let me know if you have any other questions.
False, it would equal zero.
Answer:
The true average weight of geese is less than or equal to 40 pounds
Step-by-step explanation:
The null hypothesis and the alternative hypothesis are two <u>mutually exclusive</u> statements or hypotheses that are made about a population. The purpose is to find out if, through a study of the data, sufficient evidence is obtained to reject one and accept another
The null hypothesis is denoted as and the alternative hypothesis as
As they are two mutually exclusive statements then if
: The true average weight of the geese is greater than 40 pounds
the alternative hypothesis must be the opposite of the null hypothesis
: The true average weight of geese is less than or equal to 40 pounds
