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:
The hazard ratio is defined by dividing the intake dosage (C) by the reference dose (RfD)
The hazard ratio is most nearly 114.3.

Answer:
A)Percentile for Lynette, the student who is 65 in. tall is 36th
B) Asher is 22 inches tall.
Step-by-step explanation:
Percentile : It is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls
A) Find the Percentile for Lynette, the student who is 65 in. tall.
No. of students below 65 inch =9
So, Percentage of data below 65 inch =
So, Percentile for Lynette, the student who is 65 in. tall is 36th
B)Ashers height is at the 88th percentile of the distribution. Interpret this value in context. How tall is Asher
22=x
So, No. of students below or st 88th percentile = 22
So, Asher is 22 inches tall.
Answer:
The slope is 2
Step-by-step explanation:
The slope is equal to
m = (y2-y1)/(x2-x1)
= (-2-2)/(-1-1)
= -4/-2
= 2
The units of the first number are "dollars." The second number has no apparent units, so we'll consider it a "pure number". This means the product will have the units of "dollars."
The two numbers together have 2+1=3 digits to the right of the decimal point(s). This means the final product will have 3 digits to the right of the decimal point. Since one of the factors is "dollars," it seems likely the result will need to be rounded to cents (2 decimal places). We'll provide the answer both ways (with 3 and with 2 decimal places.)
With these preliminaries out of the way, we have the problem of multiplying
... 79 × 37
There are numerous methods taught for finding this product. In the end, they all amount to multiplying every digit in one number by every digit in the other number and adding the results with appropriate place values. Several methods use 2-dimensional tables or arrays in their process. Here, we will use text on a line.
... 79 × 37 = (70 +9) × (30 +7)
... = 70×30 + 9×30 + 70×7 + 9×7
... = 2100 + 270 +490 + 63
... = 2100 +760 +63
... = 2860 +63
... = 2923
Putting the decimal point 3 places from the right, and adding the dollar sign gives our product:
... $0.79 × 3.7 = $2.923 ≈ $2.92
