Total number of tables in the cafeteria = 20
65% of the tables = 
= 13
Each table has 6 chairs.
So, total number of chairs that 65% of the tables have = 13 × 6 = 78.
35% of the tables = 
= 7
Each table has 4 chairs.
So, total number of chairs that the remaining 35% of the tables have = 7 × 4 = 28.
Hence, total number of chairs in the hospital cafeteria = 78 + 28 = 106.
Answer:
2401
Step-by-step explanation:
Given that we want to estimate average income in a population.
The standard deviation of income in the population is $1,000
We want confidence interval around our estimate to be +/- $40
i.e Margin of error = 40
We know that margin of error = Std error * Z critical for 95%
i.e. 
Std error = 
Together we get
Answer=6
Given the information, the following equation can be made, where x is equal to the number of cases she needs to buy.
160=16+24x
subtract 16 from both sides
144=24x
divide both sides by 24
6=x
She will have to buy 6 cases to have a total of 160 water bottles.
Answer:
StartFraction 8 Over 25
Step-by-step explanation:
What is the product of StartFraction 4 Over 5 EndFraction times two-fifths?
Mathematically =
StartFraction 4 Over 5 EndFraction = 4/5
Two- fifths = 2/5
Hence,
The product of StartFraction 4 Over 5 EndFraction times two-fifths
= 4/5 × 2/5
= 8/25
The correct option =
StartFraction 8 Over 25 EndFraction
We are given that the elevator is descending, so the coefficient of t must be negative. The elevator's initial position is 500 feet above the ground, so this is a positive value of +500. Therefore the only choice that fits these is h(t) = -5t + 500.
