Answer: The theoretical probability of the coin landing heads up is 0.7
Step-by-step explanation:
Hi, to answer this question we simply have to divide the number of times that the coin lands heads up (42 times) by the number of times that the coin was flipped:
Mathematically speaking:
42 /60 = 0.7 (decimal form)
The theoretical probability of the coin landing heads up is 0.7
For the or percentage form we simply multiply the result by 100:
0.7 (100) = 70%

Answer:
(2,-7)
Step-by-step explanation:
Plug in the numbers to test and see if it gives you -17 and -8.
Option 1. 2(-4)+3(2)
= -8+6 = -2. Not it.
Option 2. 2(2)+3(-7)
4 - 21 = -17 Works. Try the second equation to make sure.
3(2)+2(-7)
6-14 = -8. Works.
(2,-7) is the answer.
C= 26. you square 10 = 100. Square 24=576. Add them together= 676 Square root 676= 26
