Step-by-step explanation:
Yes, treatment was randomly assigned to the dogs.
What is randomized design?"A randomized design is considered as a type of experiment which is assigned to different types of treatment by conducting different experiment to different groups."
According to the question,
A veterinarian conducts an experiment to check which one is more beneficial glucosamine alone or glucosamine with chondroitin.
A veterinarian conducts experiment on 32 dogs by dividing them into two groups of 16 each randomly and done his experiment. 16 dogs are given the glucosamine treatment and other 16 are glucosamine with chondroitin.
After six months , health of each dog is measured and compared.
Hence, we conclude that yes, treatment was randomly assigned to the dogs is the correct option.

Which expression is best for finding the area of the polygon?
Using a starting position p, a speed s, and a time t, write two expressions for an ending position. One expression should show the result of moving right, and one expression should show the result of moving left.
going right:
going left:
Answer:
Step-by-step explanation:
We can use signed numbers to represent the position of an object along a line. We pick a point to be the reference point, and call it zero. Positions to the right of zero are positive. Positions to the left of zero are negative.
When we combine speed with direction indicated by the sign of the number, it is called velocity. For example, if you are moving 5 meters per second to the right, then your velocity is +5 meters per second. If you are moving 5 meters per second to the left, then your velocity is -5 meters per second.
If you start at zero and move 5 meters per second for 10 seconds, you will be 5⋅10=50 meters to the right of zero. In other words, 5⋅10=50 .
If you start at zero and move -5 meters per second for 10 seconds, you will be 5⋅10=50 meters to the left of zero. In other words,
−5⋅10=−50
In general, a negative number times a positive number is a negative number.

An economy package of cups has 960 green cups. If the green cups are 40% of the total package, how many cups are in the package?
Answer: 2400 cups
Step-by-step explanation:
total # of cups = x
# of green cups = 960
% of green cups of total = 40%
# green cups/# of total cups = % of green cups/% of total cups
960/x = 4/10
9600 = 4x
2400 = x
What is the measure of each angle in a regular nonagon?
state whether the following statement is true or false: y= -x2 + 6x - 10 does not intersect the x-axis.
Answer:
True
Step-by-step explanation:
Here, we want to check if the given equation does not intersect the x-axis
if it does not, then it has no real root
If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis
The formula for the discriminant is;
D = b^2-4ac
In the question;
a = -1 , b = 6 , c = 10
so;
D = 6^2-4(-1)(10)
D = 36-40
D = -4
Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis

B. Ronit has 32 bananas. She started with 12 bananas. She bought 4 bunches of the same number (x) . How many bananas were in each bunch?
Step-by-step explanation:
This one is right because if you were to actually solve this problem the equation would be the exact same
She has 32 bananas (=32)
She started with 12 (12+)
and she bought 4 more bunches, but we don't know how many are in each bunch, which would be X
12+4x =32

Given: 5x + 3 > 4x + 7.
Choose the graph of the solution set.
[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ A \ is \ correct . }}}[/tex]
Step-by-step explanation:For the number line refer to the attachment :
A linear inequality is given to us . And we need to find the correct number line. So the given linear inequality is :-
[tex]\bf \implies 5x + 3 > 4x + 7 \\\\\bf\implies 5x - 4x > 7 - 3 \\\\\bf\implies \boxed{\red{\bf x > 4 }}[/tex]
This implies that the value of x is Greater than 4 . That is the inequality can have all the values more than 4. So when we see the given number lines we see that the first number line represents all values greater than 4 .
Hence the first graph of the solution set represents the given linear inequality.Answer: B is correct
Step-by-step explanation: Tried a on the test, got it wrong, then tried b and got it right.

may 3rd -> july 15th = 73 days
500*0.06 = 30
30 = how much he makes in one day (so he has 530 after 1 day)
30*73 = 2190
500 + 2190 = 2690
9.
210/7 = 30
1% for 3 years = 30
1% for 1 year = 10
100% for 1 year = 1000
2000*0.06 = 120
11.
54,000*0.08 = 4320
54,000/4320 = 12.5
