Answer:
Step-by-step explanation:
y = C(x - 1/3)(x - 1/3)(x + 1/4)
y = C(x² - 2/3x + 1/9)(x + 1/4)
y = C(x³ - 2/3x² + 1/4x² + 1/9x - 1/6x + 1/36)
y = C(x³ - 5/12x² - 1/18x + 1/36)
now to account for the y intercept (x = 0)
-3 = C((0)³ - 5/12(0)² - 1/18(0) + 1/36)
-3 = C(1/36)
C = -108
distribute the C term across all variables.
y = -108x³ + 45x² + 6x - 3
we can verify our solution using a plotting calculator.
Answer:
1. 75
2. Cornbits
Step-by-step explanation:
1. 12/100 = 9/x
x = 75
2. Tasty Oats || 100/12 = 8.33g protein/gram cereal
Cornbits || 45/5 = 9g protein/gram cereal
x=3, you can find this by using finding common bases for equation b because 243=3^5. Because of that you can get rid of three on both sides to get the equation 2x-1=5 and then just solve for x to get x=3. For the first equation 5^3=625 so that also proves x=3.

Answer:
a)
Mean = sum of all numbers in dataset / total number in dataset
Mean = 8130/15 = 542
Median:
The median is also the number that is halfway into the set.
For median, we need to sort the data and then find the middle number which in our case is 546. Below is the sorted data
486 516 523 523 529 534 538 546 548 551 552 558 566 574 586
Standard Deviation (SD). Here X represents dataset and N= count of numbers in data
As per the SD formula, which is Sqrt ( sum (X_i - Meanx(X))/(N-1))
SD= 25.082
2) Formula for coefficient of skewness using Pearson's method (using median) is,
SK = 3* ( Mean (X) - Median(X))/(Standard Deviation) = 3*(542-546)/25.082 = -0.325
3) coefficient of skewness using the software method is also same which is -0.325
Answer:
3 is ans
Step-by-step explanation:
1st remove 1st braket.then we know that + and - = -.....
so 5(-2)=5-2=3
