A) (32x² + 24x +12) / 16. Notice that the GCD of 32, 24 and 12 is 4
then let's factorize:

4(8x² + 6x + 3) / 16. Now simplify numerator & denominator by 4

Hence a) = (8x² + 6x + 3) / 4

b) 35/(42x² - 49x +21); the GCD (of denominator) of 42, 49 and 21 is 7
then let's factorize:
35/[7(6x² -7x +3); Notice that 35 = 7.5 ; 7.5/ 7(6x²-7x+3)
Now simplify numerator & denominator by 7

Hence b)= 5/(6x²-7x+3)


Now do the same for the others.

According to the manufacturer, about 26% of sour candy in a package of Sandy's Sours are grape. What is the probability that the
Leto [7]

Answer:


Step-by-step explanation:

We assume that there are 100 sour candies, Thus-  

26 % of candy are grape implies that 26% of 100 candies are grape that is equal to 26

Now remaing candies that are not grape are 100-26 = 74

Based on the rule of multiplication:

P(A ∩ B) = P(A)/ P(B|A)  

 In the beginning, there are 26grape candies, probability of choosing first grape candy =  26C1 = 26

 After the first selection, we replace the selected grape candy so there are still 100 candies in the bag P(B|A) =  100C3 = 100 x 99 x 98 x 97!/3! X 97!

= 50 x 33 x 98

So probability =1/ 50 x 33 x 98 x 26

= 1/4204200

Joseph's lunch at a restaurant costs 13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax
Musya8 [376]

Answer:

The cost before tax with tip is $15.21.

Step-by-step explanation:

To calculate percentage, take the percent (17%) and take its decimal form. This means 17% is 0.17 (like 50% would be 0.5). multiply the number you want the percentage of by the decimal form. 13*0.17=2.21. Add this to the cost before tax and before tip. 13.00+2.21=15.21. The cost before tax with tip is $15.21.
