Answer:
25%
Step-by-step explanation:
Let us first derive an equation for the productivity.
Given
No. of houses = 1 (Assumption)
Amount of Chemicals = 30 (10 x A, B, C)
Now the formula for productivity is as follow
Productivity % (P) = (Output/Input) * 100
Assuming the current productivity is 100%. We get the value for required output but using the value of 30 (Amount of Chemicals) as Input
Since we now know the value for desired output. We replace the value of input by 40, since 10 lbs of Chemicals have been increased per house.
The new Productivity is 75%
There is a reduction of 25% in productivity
In 565656 years Daniel will be 555 times as old as he's right now how old is he right now
Let x be his current age.
"In 565656 years" can be represented by the expression x+565656.
"Will be 555 times as old as he's right now" can be represented bas the expression 555x.
The whole question means that the age of Daniel in 565656 years will be 555 times his age now so x+565656 = 555x.
Solving this equation will find x, so his current age.
x+565656 = 555x
You subtract an x of each side, to have variables on a side, and numbers on an other:
565656 = 555x - x
565656 = 554x
You divide each side by 554
x = 1021.
So Daniel is currently 1021 years old.
Answer:
3.527 > 3.518 is the answer
Answer:
The random variables which has a distribution that can be approximated by a binomial distribution is:
c. The number of students in the sample who scored above average on the SAT.
Step-by-step explanation:
The binomial distribution in this scenario will be between the number of students in the sample who scored below average on the SAT and the number of students who scored above average. Variables that have a binomial distribution must meet these four conditions:
1: The observed number of students who sat for the SAT 'n' is not variable.
2: Each student's score (observation) is purely independent of each other, either above or below average scores.
3: Each student's score (observation) shows one of the two outcomes ("success" or "failure"). Those below average are "failures." Those above average are "successes."
4: The outcome probability of "success" 'p' for each student is the same.
