Asalt solution having a concentration of cin = 2 pounds per gallon flows at a rate of ˙vin = 10 gallons per minute into a 125-gallon capacity tank, while the well-stirred solution is being pumped out at a rate of ˙vout = 5 gallons per minute. if the tank initially contained 500 pounds of salt dissolved in 50 gallons of water. when the amount of salt in the tank reach minimum?

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

answer: r there any options?

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

answer: b
