Yes you can use the discriminant of a quadratic/polynomial. For instance, if

there is one real root. If

there are two real roots and i

there are no real roots
The discriminant comes from the quadratic equation, which is the following.
Answer:
The mean is 0.32 and the standard deviation is 0.0122.
Step-by-step explanation:
Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.
Of the respondents, 48% said they put their shirt on first.
32% of all adults actually put their shirt on first
i.e. sample proportion is 48% while population proportion is 32%
Hence sampling distribution follows a distribution with mean = population proportion p
Hence here mean = 0.32
Std deviation of sampling distribution = 
Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.
is right
Answer: I think it’s 225
Explanation: 1,500 • .15= 225
One ton = 2000 lbs
Therefore, 1.5 tons = 3000 lbs
3000-300=2700lbs
