Answer:
657 pounds
Step-by-step explanation:
Given
Represent the amount of fertilizer with x and the yield with y.
So, we have:
Required:
Determine the yield (y) when fertilizer (x) is 73ft^3
Using linear interpolation, we have:
Substitute the x and y values using
and
;
We have:
Open bracket
To solve for y when x = 73.
We simply substitute 73 for x
<em>Hence, the yield for 73 cubic feet is 657 pounds</em>
Answer:
± 3
Step-by-step explanation:
let n be the number then the number squared is n² , so
6n² = 54 ( divide both sides by 6 )
n² = 9 ( take the square root of both sides )
n = ± = ± 3
That is the number is 3 or - 3
(b) 40 * = 40 *
= 8
(c) 360 - (72 + 144 + 81) = 360 - 297 = 63
(d) =
Answer:
Raul did better in biology test relative to the rest of the class.
Step-by-step explanation:
We are given two situations;
Now, we have to find on which test did he do better relative to the rest of the class. For this we will calculate z score for both the situations;
The z score value is given by, Z = ; where,
= mean
= standard deviation
For 1st situation; z score = = 0.625
For 2nd situation; z score = = 2
So, it is clear that 2nd situation is better as it has higher z score.
Therefore, Raul did better in biology test relative to the rest of the class.
