Answer:
The variable that may change in response to the increase of the drug is the GAD symptoms by a 37,5%.
Step-by-step explanation:
According to the results of the first experiment with a mass of 200 mg of Drug R, they obtain a reduced of the GAD symptoms by a 25 percent evidenced by the Hamilton Anxiety Scale.
If they decided to increase the mass of Drug R to 300 mg the results expected are a increase of the porcentange of the reduced symptoms of generalized anxiety disorder, according to the tendence of the first hypothesis and the Hamilton Anxiety Scale.
We can express this increase by using the three simple rule. Where if 200 mg of Drug R reduced the 25% of the GAD symptoms, if we increase to 300 mg of Drug R how much porcentage this amount will be reduced.
Doing the maths 300mg × 25%=7500mg%,
⇒ 7500mg% ÷ 200mg = 37,5%.
<u>In conclusion</u> if they increased the mas of Drug R to 300 mg they will be reduced the generalized anxiety disorder (GAD) to a 37,5%.
Answer:
uv - 10u
Step-by-step explanation:
To distribute a problem, you have to multiply what is on the outside of the parenthesis with what is on the inside.
u · v = uv
u · -10 = -10u
Combined, u(v - 10) = uv - 10u.
Answer:
The Large Box Weighs 18 kg, and the small box weighs 6.5 kg
Step-by-step explanation:
Let a= the weight in kg of a large box
Let b= the weight in kg of a small box
Multiply both sides of (1) by 4 and subtract (2) from (1)
1. 20a+8b=412
2. -3a-8b= -106
17a=306
a=18
and
5*8+2b=103
90+2b=103
2b=13
b=6.5
