multiplicative inverse of -26/7 is -7/26
39/8. Multiply the denominator (bottom number) and the whole number; then add the numerator (top number) to the product. The denominator will remain the same as in the mixed fraction.
They are dependent events, because the probability of the second event depends on the result of the first event
If you replace the marble before picking up the second marble, then the first event didn't affect the second result ant the events were independent.
Given that you did not replace the marble, the second pick up has different probailities depending on the first result.
Answer:
b=4√10
Step-by-step explanation:
AB²=AC²+BC²
14²=b²+6²
b²=14²-6²=160
b=√160=4√10
5(2a-6) = 10a-30 you would just multiply 2a and -6 by 5
