Researchers at a veterinary hospital wish to test a new drug developed for treating degenerative joint disease (DJD) in dogs. A group of 30 Great Danes, 50 Labradors, and 40 Mastiffs is to be used. The researchers randomly assign 15 of the Great Danes, 25 of the Labradors, and 20 of the Mastiffs to the traditional drug for treatment. The remaining dogs are assigned to the new drug. The major reason for separate assignment for each breed of dog is that
A) This is a large study with 120 dogs.
B) This design uses matched pairs to detect the new-drug effect.
C) The new drug may affect Great Danes, Labradors, and Mastiffs differently.
D) The new drug may affect dogs with DJD differently than dogs without DJD.
E) There must be an equal number of dogs in each of the two treatment groups.
Answer:
Testing a new drug developed for treating degenerative joint disease (DJD) in dogs
The major reason for separate assignment for each breed of dog is that:
E) There must be an equal number of dogs in each of the two treatment groups.
Step-by-step explanation:
One of the two groups is the experimental group (treatment group). It receives the new treatment whose effect the researchers are interested in finding out. The other half (group) is called the control group. It receives the traditional drug. This control group (also called the comparison group) ensures that the treatment the researchers are giving to the dogs causes the expected experimental results. This means that the results of the two groups are compared to determine the different effects.

Use elimination to solve the system of equations given by 3x - 2y = 10 and 5x + 2y = 6
Answer:
x = -2 y= -8 and 8
Step-by-step explanation:
Since there is an equal number of y's, they cancel out when subtracting. You can put either equation on top. You will get same answer.
To find x:
If you do (3x - 2y = 10) - (5x + 2y = 6), you will get -2x=4. Divide both sides by -2, and get x = -2.
If you do (5x + 2y = 6) - (3x - 2y = 10), you will get 2x=-4.Divide both sides by 2, and get x = -2.
To find y:
Substitute -2 for x in either equation. It doesn't matter.
For 3(-2) - 2y = 10:
3(-2) - 2y = 10 ––Multiply
-6 - 2y =10 ––Add 6 to both sides to get y alone
-2y = 16 ––Divide by -2
y = -8
For 5x + 2y = 6:
5(-2) + 2y = 6 ––Multiply
-10 + 2y = 6 ––Add 10 to both sides to get y alone
2y = 16 ––Divide by 2
y = 8

PLEASE HELP ILL GIVE FOLLOW AND BRAINLIEST
Answer:
Step-by-step explanation:
4x + 9y = -8
6x + 5y = 42
12x + 27y = -24
-12x - 10y = -84
17y = -108
y= -108/17
4x + 9(-108/17) = -8
4x - 972/17= -136/17
4x = 836/17
x = 209/17
y = -108/17

Bill purchases a bond for $1,200. It pays 7% simple annual interest and matures in 8 years. How much interest will Bill earn
after the bond reaches maturity?
Answer:
672
Step-by-step explanation:
I'm going to assume that this is a zero-coupon bond
simple interest is as follows
PV(1+it)
we have
1200(1+.07*8)
1200*1.56=1872
This is the accumulated value
to find the interest earned we use the following equation
AV-PV
we have
1872-1200=672

Answer:
y= 93/5x + 3
Step-by-step explanation:
Find the gradient-
m= [tex]\frac{96-3}{5-0}[/tex]= 93/5
Substitute into-
y-y1=m(x-x1)
y-3=93/5(x-0)
y= 93/5x + 3
