Answer:
The sample mean would most likely be 50 centimeters.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
The mean of the population is 50 centimers.
So, by the Central Limit Theorem, the sample mean would most likely be also 50 centimeters.
The given statement is a false statement because -12 is not equal to -15 and also -15 is less than -12 which are correct answers would be Options (A) and (D).
<h3>What is inequality?</h3>
Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The given statement as:
⇒ -12 ≤ -15
Since -12 and -15 are not equal and -15 is smaller than -12, the preceding statement is incorrect.
So the following statements are correct:
It is a false statement because -12 is not equal to -15.
It is a false statement because -15 is less than -12.
Hence, the given statement is a false statement because -12 is not equal to -15 and also -15 is less than -12 which are correct answers would be Options (A) and (D).

Answer: one with change mane I’m pretty sure? Really sorry if that’s not right
Step-by-step explanation:
Answer:
the coefficient of x is 1
Step-by-step explanation:
In the expression ax²+bx+c=0
a is the coefficient of x²
b is the coefficient of x
2+x²+x = x²+x +2 = 1x²+1x +2 =
So in this expression right above the coefficient of x is 1
Answer: 4d + 3
Step-by-step explanation:
Megan's daughter's age = d
Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:
= (4 × d) + 3
= 4d + 3
Therefore, Megan's age is 4d + 3.
For example, if the daughters age is 7 years, Megan's age will be:
= 4d + 3
= 4(7) + 3
= 28 + 3
= 31 years
