Answer:

Step-by-step explanation:
Total number of tiles: 11 (obtained from counting the letters in probability)
Probability of picking the letter "i" the first time:
There are 2 letter "i's", and 11 total options, so the probability of picking an "i" is:

Probability of picking the letter "i" the second time:
We now have one less letter in the bag, as the first letter "i" was not replaced.
This means we now only have 1 letter "i", and 10 total options, so the probability of picking the last "i" is:

When you have two probabilities that are dependant on each other, you multiply them to get the probability of one, given that the other has happened.
Total probability:
Simplify by dividing by 2:

Answer:
The discriminant of the quadratic equation is 0
Step-by-step explanation:
Here, we want to calculate the discriminant of the given quadratic equation
Mathematically, we have the discriminant calculated by the following formula;
D = b^2 - 4ac
where;
b represents the coefficient of x which is -2
a is the coefficient of x^2 which is 1/7
c is the last number which is 7
Substituting these values;
D = (-2)^2 -4(1/7)(7)
D = 4 - 4
D = 0
Answer:
x > 1
Step-by-step explanation:
2x+5>7
move constant to right
2x>5-7
subtract 7 and 5
2x>2
divide both sides
x > 1
