Step-by-step explanation:
A company wants to test a new brand of dog food that has added omega-3 oils for healthy, shiny coats.
The company selects two groups of volunteers who have dogs as pets. They give each person in both groups a month's supply of dog food. Each bag of dog food is unlabeled. One group is given the dog food with the added omega-3 oils, and the other group is given a brand of dog food without the added omega-3 oils. Both groups are asked to feed their dogs the food the company gave them and report whether they noticed an improvement in their dogs' coats.
Which statement is correct?
A.
The experiment is blinded because the volunteers in both groups and the company are all unaware of which group received the dog food with omega-3 oils.
B.
The experiment is not blinded because the volunteers in both groups and the company are all unaware of which group received the dog food with omega-3 oils.
C.
The experiment is blinded because the volunteers in both groups are unaware of which dog food they received.
D.
The experiment is not blinded because the volunteers in both groups are aware of which type of dog food they received.
Answer: The experiment is blinded because the volunteers in both groups are unaware of which dog food they received.
The statement which is correct about the experiment given to both volunteers is "The experiment is blinded because the volunteers in both groups are unaware of which dog food they received".
What is an experiment?An experiment refers to a test under controlled conditions made to either demonstrate a known truth, examine the validity of a hypothesis or determine the efficacy of something previously untried.
The experiment is blinded to the two volunteer groups because the supply of dog food given to both groups is unlabeled and they are both unaware of the food supply which contains the omega-3 oils.

Amber and Jimmy both drove their cars to a theme park. They both drove a steady pace for most of the trip. It took Amber exactly 2 hours to travel the 153 miles to the park. Jimmy's trip is modeled by the graph below.
Amber and Jimmy's speed for driving their cars to the theme park is 76.5 miles per hour.
What is speed?Speed refers to the rate of movement of a vehicle or person.
The speed can be computed by dividing the total distance by the time consumed.
Data and Calculations:Total distance = 153 miles
Time is taken to cover distance = 2 hours
Speed per hour = 76.5 miles (153/2)
Question Completion:What is Amber and Jimmy's speed?
Thus, Amber and Jimmy's speed for driving their cars to the theme park is 76.5 miles per hour.

Step-by-step explanation:
Will a truck that is 10 feet wide carrying a load that reaches 12 feet above the ground clear the semielliptical arch on the one-way road that passes under the bridge shown in the figure on the right? 13 ft --- 52 ft It will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately (Round to two decimal places as needed.) feet.
Figure is missing, so i have attached it.
Answer:
it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft
Step-by-step explanation:
The standard form of equation of an ellipse is;
x²/a² + y²/b² = 1
From the figure in the image attached, we can see that the radius is; a = 52/2 = 26 ft
While the value of b = 13 ft
Thus;
x²/26² + y²/13² = 1
x²/676 + y²/169 = 1
We want to find the height of the archway of the bridge 5 feet from the center.
Thus, we will plug in 5 for x to get;
5²/676 + y²/169 = 1
(25/676) + (y²/169) = 1
Multiply through by 676 to get;
25 + 4y² = 676
4y² = 676 - 25
y² = 651/4
y² = 162.75
y = 12.76 ft
Thus height of the truck is 12 ft and so it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft
Height of the archway 5 feet from the center is required.
The height of the archway 5 feet away from the center is 12.757 feet.
Semi-major axis = [tex]a=\dfrac{52}{2}=26\ \text{feet}[/tex]
Semi-minor axis = [tex]b=13\ \text{feet}[/tex]
The formula for ellipse is
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1\\\Rightarrow \dfrac{x^2}{26^2}+\dfrac{y^2}{13^2}=1[/tex]
At 10 feet is the width of the truck.
The truck is passing through the center so the [tex]x=\dfrac{10}{2}=5[/tex]
[tex]\dfrac{5^2}{26^2}+\dfrac{y^2}{13^2}=1\\\Rightarrow y=\sqrt{(1-\dfrac{5^2}{26^2})\times 13^2}\\\Rightarrow y=12.757\ \text{feet}[/tex]
Now [tex]y=12.757\ \text{feet}>12\ \text{feet}[/tex]
So, the height of the archway 5 feet away from the center is 12.757 feet.

Miguel's town voted on a new speed limit. Of the votes received, 16 were in favor of the new
speed limit and 16 were opposed. What percentage of the votes were in favor of the new
speed limit?
Write your answer using a percent sign (%).
Answer:
Exactly 50% of the votes were in favor of a new speed limit.
Step-by-step explanation:
We are given that 16 votes were in favor of a new speed limit and 16 votes were not. From this, we can determine the total amount of votes.
[tex]16 + 16 = 32 \ \text{total votes}[/tex]
Then, using this information we can find the percentage of how many were in favor of the vote.
If 16 of the votes were in favor, we can divide these votes by the total votes to get a percentage.
[tex]\displaystyle \frac{16}{32}=\frac{8}{16}=\frac{4}{8}=\frac{2}{4}=\frac{1}{2}=0.5[/tex]
Then, we multiply this decimal by 100 in order to convert our answer to a percentage form.
[tex]\displaystyle 0.5 \times 100 = 50\%[/tex]
Therefore, 50%, or half of the voters, were in favor of a new speed limit.
