Answer:
x=3+sqrt{6}
Step-by-step explanation:
1) x + 2xyz
2) 3x + y + z
3) 2x³y + y²x - 3x + 4
4) 9x³yz
Least to greatest: 2 , 1, 4, 3,
Let us assume that x = 3; y = 2; z = 1 and we disregard the coefficients
1) x + 2xyz ⇒ 3 + (3)(2)(1) = 9
2) 3x + y + z ⇒ 3 + 2 + 1 = 6
3) 2x³y + y²x - 3x + 4 ⇒ (3³)(2) + (2²)(3) - 3 = 63
<span>4) 9x³yz </span>⇒ (3³)(2)(1) = 54
Least to greatest ; 2) 6 ; 1) 9 ; 4) 54 ; 3) 63.
We disregarded the coefficients because the expressions are organized based mainly on their degree.
Answer: The proportion that will qualify is 0.0314 or 3.14%.
First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.
(128 - 141) / 7 = -1.86
Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.
