Answer:
19/3x+3 or 6 1/3x+3
Step-by-step explanation:
lets simplify:
1/3(4x+9)+5x.
distribute 1/3 :
4/3x+3+5x
add x together:
4/3x+5x=19/3=6 1/3.
final answer:
19/3+3

Step-by-step explanation:
So, lets just go by segment to segment, using the process of elimination to see which graph is correct.
So the first segment of all the graphs is 18-19.9.
Lets look at the numbers given to us, and see how many times values between these two numbers occur. I see 19.9 and 18.6. This is two values.
This eliminates answer C, which has three values(a frequency of 3).
All the others have 2 values however, so lets keep going.
Next we have 20-21.9. I see 9 values that are in between 20-21.9:
20.7, 21.2, 20.5, 20.4, 21.6, 21.4, 21.5, 21.5, 21.9
Both B and D have graphs with 9 values that are between 2-21.9, however A only has 8 values.
Now lets look at 22-23.9. I see 8 values between 22-23.9:
22.2, 22.7, 22.1, 23.1, 23.8, 22.6, 23.9, 23.4
This eliminates D, which only has 7 values, but B does have 8 values.
So this means that B is the answer!

A large tank is filled to capacity with 700 gallons of pure water. Brine containing 4 pounds of salt per gallon is pumped into the tank at a rate of 7 gal/min. The well-mixed solution is pumped out at a rate of 14 gallons/min. Find the number A(t) of pounds of salt in the tank at time t.
Answer:
[tex]A(t) = 1400(1 - e^{\frac{-t}{50}})[/tex]
Step-by-step explanation:
The net mass flow rate dA/dt = mass flow rate in - mass flow rate out
mass flow rate in = concentration of brine in × brine flow rate in = 4 lb/gal × 7 gal/min = 28 lb/min
Let A(t) be the amount of salt at time t. The concentration of salt in the tank at time, thus C = amount of salt/volume of tank = A(t)/700 lb/gal.
Since the well mixed solution is pumped out at a rate of 14 gal/min, the mass flow rate out = concentration of salt in tank × volume flow rate out = A(t)/700 lb/gal × 14 gal/min = m(t)/50 lb/min
So, dA/dt = mass flow rate in - mass flow rate out
dA/dt = 28 lb/min - A(t)/50 lb/min
dA/dt = 28 - A(t)/50
dA/dt = [1400 - A(t)]/50
separating the variables, we have
dA/[1400 - A(t)] = dt/50
integrating both sides, we have
∫dA/[1400 - A(t)] = ∫dt/50
-1/-1 × ∫dA/[1400 - A(t)] = ∫dt/50
1/-1 × ∫-dA/[1400 - A(t)] = ∫dt/50
-1 × ㏑[1400 - A(t)] = t/50 + C
-㏑[1400 - A(t)] = t/50 + C
㏑[1400 - A(t)] = -t/50 - C
taking exponents of both sides, we have
[tex]1400 - A(t) = e^{\frac{-t}{50} - C} \\1400 - A(t) = e^{\frac{-t}{50}}e^{-C}\\1400 - A(t) = Be^{\frac{-t}{50}} ( B = e^{-C}) \\A(t) = 1400 - Be^{\frac{-t}{50}}[/tex]
when t = 0, A(0) = 0. So,
[tex]A(t) = 1400 - Be^{\frac{-t}{50}}\\A(0) = 1400 - Be^{\frac{-0}{50}}\\0 = 1400 - Be^{0}\\0 = 1400 - B\\B = 1400[/tex]
So,
[tex]A(t) = 1400 - 1400e^{\frac{-t}{50}}\\A(t) = 1400(1 - e^{\frac{-t}{50}})[/tex]
Three friends went to a fundraiser at a local restaurant. Each plate cost $7.95, which included a drink. A tip of 20% was left for the waitress. How much was the total cost of the meals including tip?
A.$23.85
B. $24.05
C. $28.62
D. $29.65
Answer:
C. $28.62
Step-by-step explanation:
3 · $7.95 = $23.85
[tex]\frac{y}{23.85} :\frac{20}{100}[/tex]
y · 100 = 20 · 23.85
100y = 477
100y ÷ 100 = 477 ÷ 100
y = $4.77
$23.85 + $4.77
$28.62

A study of color in tiger beetles is conducted to gain evidence to support the contention that the proportion of yellow beetles may vary from locality to locality. A sample of 500 beetles caught in one season near East Setuket, NY, yielded 92 yellow ones. A catch of 251 from Queens, NY, contained 14 yellow individuals. What distribution can be used to derive the exact sampling distribution for proportion of yellow tiger beetles
Answer:
Binomial distribution
Step-by-step explanation:
Each tiger:
For each tiger, there are only two possible possible outcomes. Either it is yellow, or it is not. The probability of a tiger being yellow is independent of any other tiger. This means that the binomial probability distribution is used to solve this question.

One plumber charges a flat fee of $50 to come to the house and then
$20 per hour. If h represents the number of hours that the plumber spent
fixing the problem and C represents the total charge, which of the following
equations shows how to determine the total fee charged?
C=50+20h
C=(50+20)h
C=h+50+20
C=20+50h
Answer:
C=50+20h
Step-by-step explanation:
Since 20 is going to be added every hour, that is the h value. Since 50 is the the initial payment, that is the other value
The equation for total fees charged, if One plumber charges a flat fee of $50, The per hour fees = $20, is C = 50 + 20h, so option A is correct.
What is equation?A formula known as an equation uses the equals sign to denote the equality of two expressions. Equation: A declaration that two expressions with variables or integers are equal.
Given:
One plumber charges a flat fee of $50,
The per hour fees = $20,
Write the equation for the total charged fees as shown below,
Total charge = One-time fees + per-hour fees × number of hours
Assume C represents the total charge, h represents the number of hours, then,
C = 50 + 20 × h
C = 50 + 20h
