Answer:

Factors (12 - 7x) ( 12 +7x ) .

Step-by-step explanation:

Given : 144 − 49x².

To find : Which is a factor .

Solution : We have given 144 − 49x²

We can write 144 = (12)².

49 = (7)².

Then (12)² - (7x)².

By the formula (a)² - (b)² = (a-b) ( a+b) .

Here, a = 12 , b = 7x

(12)² - (7x)² = (12 - 7x) ( 12 +7x ) .

Therefore, Factors (12 - 7x) ( 12 +7x ) .

You spin the spinner and flip a coin. Find the probability of the compound event.

Mademuasel [1]

Answer:

The probability of spinning an even number and flipping heads is 1/4

Step-by-step explanation:

You spin the spinner and flip a coin.

A spinner that has 1 of each number, 1-6

Total events =12

(1,H),(2,H),(3,H),(4,H),(5,H),(6,H)

(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)

We are supposed to find probability of spinning an even number and flipping heads

Favorable events : (2,H),(4,H)(6,H) = 3

Total events = 12

The probability of spinning an even number and flipping heads = $\frac{3}{12}=\frac{1}{4}$

Hence The probability of spinning an even number and flipping heads is 1/4
