Try this solution:
1. for probability of both televisions work:
2. for probability of at least on is defective (it means, the sum = one is defective and two are defective):
- for P(1defective);
- for P(2defective);
totaly for at least one is defective:
Answer:
x=-10
Step-by-step explanation:
the picture is showing
1+1= -1 + -1 + -1 + -1 + -1 + -1 + -1 + -1 + -x
simplified its:
2= -8 + -x
I think that the answer is x=-10 cuz if u did -8 - -10 then the two negatives make a positive and it makes 2 but idk if the minus sign before the x means minus or negative so this might be the answer but dont blame me if im wrong. I warned you. If its right plz write that.
350 - 213 - 155 + 78 = 60 students not in either
Given a variable, x, the compound ineaquality representing the range from a to b inclusive of the variable is given by
where a is the least value and b is the greatest value.
Thus, given a variable f, representing the frequencies for the three octaves of a <span>typical acoustic guitar.

Where the range of the frequencies is between 82.4 Hertz and 659.2 Hertz inclusive.
The complex inequality, representing <span>the range of frequencies for a guitar tuned to "concert pitch"</span> is given by
