Step-by-step explanation:
Medical researchers studying a medication in male and female patients 20 to 29 years old noticed that, up to a certain amount, a larger concentration of an active ingredient lead to greater levels of symptom relief.
What is the explanatory variable?
A) age of patient
B) gender of patient
C) amount of symptom relief
D) concentration of active ingredient
Answer:
D
Step-by-step explanation:
The required explanatory variable is concentration of active ingredients. Option D is correct.
Given that,
From the paragraph, "Medical researchers studying a medication in male and female patients 20 to 29 years old noticed that, up to a certain amount, a larger concentration of an active ingredient lead to greater levels of symptom relief." it is to be determined which is an explanatory variable.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
A) age of patient = Not explanatory
B) gender of the patient = Not explanatory
C) amount of symptom relief = Not explanatory
D) concentration of active ingredient = Explanatory
Thus, the required explanatory variable is the concentration of active ingredients. Option D is correct.

The gallons of gasoline used on a car trip varies directly as the number of miles driven. If 25 gallons of gasoline has been used after driving 700 miles,how many gallons of gasoline would be used after driving 1000 miles? Round your answer to the nearest tenth
Answer:
35.7 gallons
Step-by-step explanation:
Given that:
Distance traveled = 700 miles
Gasoline used = 25 gallons
The gallons of gasoline used are directly proportional to the number of miles traveled.
To find the gallons of gasoline to be used after driving 1000 miles, we can use the unitary method in which we first of all find, how much gallons of gasoline would be used for 1 mile and then multiply the value with 1000 to find the answer.
700 miles are traveled by gallons of gasoline = 25
1 mile is traveled by gallons of gasoline = [tex]\frac{25}{700}[/tex]
1000 miles are traveled by gallons of gasoline = [tex]\frac{25}{700}\times 1000 = \bold{35.7\ gallons}[/tex]

Complete Question
Bonnie is making a dipping sauce. She mixes 150 milliliters of soy sauce with 100 milliliters of vinegar. How much soy sauce does Bonnie mix with every 1 milliliter of vinegar?
Answer:
1.5 mm soy sauce
Step-by-step explanation:
Bonnie is making a dipping sauce. She mixes 150 milliliters of soy sauce with 100 milliliters of vinegar. How much soy sauce does Bonnie mix with every 1 milliliter of vinegar?
Hence:
100 mm vinegar = 150mm soy sauce
1 mm vinegar = x
Cross Multiply
100 × x = 150 × 1
x = 150 × 1/100
x = 1.5 mm soy sauce
Hence, Bonnie mixes with every 1 milliliter of vinegarwoth 1.5 mm soy sauce

The freezing point of of gasoline is about -50 degrees Celsius, and the freezing point of water is 0 degrees Celsius. What is the difference between the freezing point of water and gasoline? Explain your answer.
Answer:
the difference is that -50 is -50 celsius from 0 hope this helps at all!?
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
0 is larger then -50 and you want the difference so minus them
0-(-50) now when 2 negative signs meet like this they turn to addition
0+50 which is 50
their difference is 50

If the measure of angle 1 is (3 x minus 4) degrees and the measure of angle 2 is (4 x + 10) degrees, what is the measure of angle 2 in degrees?
A horizontal line. A line extends from the line to form a 90 degree angle. Another line cuts through the 2 lines to form angles 1 and 2, which total 90 degrees.
32 degrees
38 degrees
58 degrees
66 degrees
Answer:
58 degrees
Step-by-step explanation:
3x-4+4x+10=90
7x+6=90
7x=84
x=12
4(12)+10=angle 2
58 degrees = angle 2

In Triangle JKL, ∠J is congruent to ∠L. Triangle J K L is shown. Ray L K extends beyond point K to form an exterior angle that is labeled sixty-seven and eight tenths degrees. What is the measure of ∠L? Enter the correct answer in the box.
Answer:
m<L = [tex]33.9^{o}[/tex]
Step-by-step explanation:
Triangle JKL is an isosceles triangle, given that <J ≅ <L. An isosceles triangle has two of its angles and sides to be equal.
The exterior angle formed = [tex]67.8^{0}[/tex]
But,
<J + <L = [tex]67.8^{0}[/tex] (the sum of two opposite interior angles is equal to the exterior angle)
Let <J ≅ <L be represented by a, so that;
a + a = [tex]67.8^{0}[/tex]
2a = [tex]67.8^{0}[/tex]
a = [tex]\frac{67.8^{o} }{2}[/tex]
= [tex]33.9^{o}[/tex]
The measure of <L is m<L = [tex]33.9^{o}[/tex] (m<L =
Thus,
m<J ≅ m<L = [tex]33.9^{o}[/tex]

If the measurement of Angle 1 = 160 degrees, what is the measurement of Angle 2?
A. 40
B. 35
C. 20
Answer:
C
Step-by-step explanation:
im pretty sure it this because it would make 180 degrees ;-;
Answer:
20 degrees
Step-by-step explanation:
angles on a straight line/ straight line angles/ supplementary angles = 180 degrees
angle 1 + angle 2 = 180 degrees
160 + angle 2 = 180
angle 2 = 180 = 160
angle 2 = 20 degrees

Calculate the force output by the larger piston of a hydraulic lift when a force of 800 N is exerted on the smaller piston. The areas of the two pistons are 20 cm2 and 500 cm2.
answer:
F2= 5kNstep by step explanation
Note the second diameter was used as 50cm and not 500cm
given
F1=800N
D1=20cm
A1=πD1^2/4
=3.142*20^2/4
=314.2cm^2
D2= 50cm
A2=πD2^2/4
=3.142*50^2/4
=1963.75cm^2
The pressure applied on the smaller relative to the bigger end is expressed as
F1/A1=F2/A2
substitute we have
800/314.2=F2/1963.75
cross multiply we have
F2=800*1963.75/314.2
F2=1571000/314.2
F2=5000N
F2=5kN
The larger Force is 5kN

t÷5/12= -3/10
Thank you if you help :)
Answer:
t = -1/8.
Step-by-step explanation:
t / 5/12 = -3/10 Invert the 5/12 and multiply:
12t / 5 = -3/10
Cross multiply:
12t * 10 = 5 * -3
120t = -15
t = -15/120 = -1/8.
