Answer:
1.5 feet
Step-by-step explanation:
1 feet = 12 inches
18 inches --> x feet
18/12 = 1.5 feet
Answer:
- (ax + by + cz)/(a + b + c)
Step-by-step explanation:
<u>In terms of the scores we calculate the sum as:</u>
<u>The number is the sum of the frequencies:</u>
<u>Mean average score is:</u>
- (ax + by + cz)/(a + b + c)
The equation governiong this relationship is y = kx. Since y = 25 when x = 60,
25 = 60k, and k=(5/12). Thus, the equation is y = (5/12)x.
If y = 30, then 30 = (5/12)x. Mult. both sides by 12/5 to obtain the value of x:
(12/5)(30) = 360/5 = 72
Ways to spot if an expression is not a polynomial:
1) If there is a negative exponent
2) If there is division by a variable
3) If the power is something other than a non-negative integer
If any of these conditions exist, the expression will not be a polynomial. Now consider the options. Option A has negative exponent, Option B involves division by a variable and Option D has a exponent which is not a number.
So, from the given options, option C is the only polynomial
