Hi There!
Area Formula: length x width = area
Solution: 12 x 4 = 48
Answer: A. 48 ft^2
Hope This Helps :)
Answer:
1. polynomial is a kind of mathematical expression
2. degree of a polynomial is the highest of the degrees of its monomials (individual terms) with non-zero coefficients
3. a coefficient is a number used to multiply a variable.
4. A exponent refers to the number of times a number is multiplied by itself
5. a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number
The value of x would be 45 because it is an equivalent triangle so the opposite side would be the same as the other side. ^-^ hope this helps.
Answer: 1.25
Step-by-step explanation:
Given: A college-entrance exam is designed so that scores are normally distributed with a mean
= 500 and a standard deviation
= 100.
A z-score measures how many standard deviations a given measurement deviates from the mean.
Let Y be a random variable that denotes the scores in the exam.
Formula for z-score = 
Z-score = 
⇒ Z-score = 
⇒Z-score =1.25
Therefore , the required z-score = 1.25
