As a result of discharges from local dry cleaner, dinitrotoluene concentration in the groundwater is 8 mg/L. RfD for dinitrotolu
bixtya [17]

Answer:

114.3

Step-by-step explanation:

If a 70kg person ingests 2L of water per day containing 8 mg/L of  dinitrotoluene, the concentration of  dinitrotoluene on that person's body is:

C=2\frac{L}{day}*8\frac{mg}{L} *\frac{1}{70\ kg}\\C=0.22857\frac{mg}{kg-day}

The hazard ratio is defined by dividing the intake dosage (C) by the reference dose (RfD)

H=\frac{0.22857}{2*10^{-3}}\\H=114.3

The hazard ratio is most nearly 114.3.

Find the mean, median, mode, and range of the data set 19, 7, 16, 2, 10, 6, 7. If necessary, round
Maslowich

Answer:

Mean: 9.6

Median: 7

Mode: 7

Range: 17

Step-by-step Explanation:

<em>Mean: add all the numbers then divide the sum by how many numbers there are </em>

19 + 7 + 16 + 2 + 10 + 6 + 7 = 67

67 / 7 = 9.57 --> 9.6

<em>Median: arrange your numbers in numerical order, count how many numbers you have (if odd, divide by 2 and round up to the position of a median number, if even, divide by 2 and go to that number in position) </em>

2, 6, 7, 7, 10, 16, 19 (7 numbers = since its odd, divide by 2 which equals 3.5, round it up to 4 and go to the number in the 4th position, in this case 7)

<em>Mode: Put the number in order again and determine which number appears the most</em>

2, 6, 7, 7, 10, 16, 19  = 7 appears twice while the rest only appears once

<em>Range: subtract the lowest value from the highest value</em>

19 - 2 = 17

4(3x + 2) =16x + 7 -4x + 1
GrogVix [38]

Answer:

All real numbers are solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(3x+2)=16x+7−4x+1

(4)(3x)+(4)(2)=16x+7+−4x+1(Distribute)

12x+8=16x+7+−4x+1

12x+8=(16x+−4x)+(7+1)(Combine Like Terms)

12x+8=12x+8

12x+8=12x+8

Step 2: Subtract 12x from both sides.

12x+8−12x=12x+8−12x

8=8

Step 3: Subtract 8 from both sides.

8−8=8−8

0=0
