To determine To solve: The equation 2 x + 3 = x . Explanation The given equation is 2 x + 3 = x . Square both sides as follows. ( 2 x + 3 ) 2 = ( x ) 2 2 x + 3 = x 2 x 2 − 2 x − 3 = 0 ( x + 1 ) ( x − 3 ) = 0 On further simplification, x + 1 = 0 or x − 3 = 0 x = − 1 or x = 3 Therefore, the solution of equation is x = − 1 or x = 4 . Check the solution by substituting x = − 1 in 2 x + 3 = x

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Find binomial probability if: x = 8, n = 10, p = 0.7 x= 3, n=5, p = 0.3 x = 4, n=7, p = 0.6 Quality Control: A factory produces light bulbs with a 2% defect rate. If a random sample of 20 bulbs is tested, what is the probability that exactly 2 bulbs are defective? (hint: p=2% or 0.02; x =2, n=20; use the same logic for the following problems) Marketing Campaign: A marketing company sends out 1,000 promotional emails. The probability of any email being opened is 0.15. What is the probability that exactly 150 emails will be opened? (hint: total emails or n=1000, x =150) Customer Satisfaction: A survey shows that 70% of customers are satisfied with a new product. Out of 10 randomly selected customers, what is the probability that at least 8 are satisfied? (hint: One of the keyword in this question is “at least 8”, it is not “exactly 8”, the correct formula for this should be = 1- (binom.dist(7, 10, 0.7, TRUE)).
