​

Answer 1

Answer:

If (-5z - 8z = 91 ), then find z

Step-by-step explanation:

If (-5z - 8z = 91 ), then find z

Answer 2

Answer:

PLEASE REFER TO THE ANSWER BELOW

Step-by-step explanation:

The probability of getting a head is 0.56 and getting a tail is 0.44.

In the experiment a coin is tossed 500 times.

Heads turns up 280 times.

The number of times tails turns up is 500 - 280 = 220

Now we have to calculate the probability of getting a head and getting a tail.

Probability of getting a head = 280/500 = 0.56.

Probability of getting a tail = 220/500 = 0.44.
