Answer:
25 gallons
Step-by-step explanation:
Let x be the number of gallons of orange juice worth $1.70 per gallon, then x gallons are worth $1.70x.
If 100 gallons of orange juice worth $2.20 per gallon, then 100 gallons are worth ![\$2.20\cdot 100=\$220](https://tex.z-dn.net/?f=%5C%242.20%5Ccdot%20100%3D%5C%24220)
Total cost is
![\$1.70x+\$220](https://tex.z-dn.net/?f=%5C%241.70x%2B%5C%24220)
Together we will get x + 100 gallons of a mixture. This mixture we will sell for $2.10 per gallon, so, x + 100 gallons of mixture is worth $2.10(x + 100).
Thus,
![1.70x+220=2.10(x+100)\\ \\17x+2,200=21(x+100)\ [\text{Multiplied by 10}]\\ \\17x+2,200=21x+2,100\\ \\17x-21x=2,100-2,200\\ \\-4x=-100\\ \\4x=100\\ \\x=25](https://tex.z-dn.net/?f=1.70x%2B220%3D2.10%28x%2B100%29%5C%5C%20%5C%5C17x%2B2%2C200%3D21%28x%2B100%29%5C%20%5B%5Ctext%7BMultiplied%20by%2010%7D%5D%5C%5C%20%5C%5C17x%2B2%2C200%3D21x%2B2%2C100%5C%5C%20%5C%5C17x-21x%3D2%2C100-2%2C200%5C%5C%20%5C%5C-4x%3D-100%5C%5C%20%5C%5C4x%3D100%5C%5C%20%5C%5Cx%3D25)

Answer:
0.0003
Step-by-step explanation:
for the indicated probability
we need to find : Probability (P) ( X > or = 30) = 1 - P( X < 30 )
z-score(30) = (30 - 14.6)/3.8 = 4.053
looking in z-tables for the corresponding probability
P(x<30) = 0.99997
indicated probability
P ( X > or = 30) = 1 - 0.99997 = 0.0003 (answer)
