Clinical literature reports that the duration of a typical cold is roughly 18 days. Researchers wanted to know if people tend to underestimate the duration of a typical cold, on average. They surveyed a random sample of 352 healthy adults in Georgia and asked them how long they think that a typical cold lasts. The researchers reported a 95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.
Which of the following is the correct interpretation for this confidence interval?
a. We are 95% confident that the sample mean duration is between 6.9 and 8.2 days.
b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.
c.There is a 95% chance that the mean duration of another random sample from this population would be between 6.9 and 8.2 days.
d. There is a 95% chance that a randomly selected individual from this population would give a response between 6.9 and 8.2 days.
Answers
Answer:
b. We are 95% confident that the population mean duration is between 6.9 and 8.2 days.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95% confidence interval of 6.9 to 8.2 days for the mean expected duration of typical cold.
This means that we are 95% sure that the true duration of a typical cold(population mean) for all health adults in Georgia is between 6.9 and 8.2, which means that the correct answer is given by option b.

The variable z varies jointly with x and y. Also, z = -75 when x = 3 and y = -5.
What equation describes this variation?
x = kyz
y = kxz
z = kxy
k = xyz
Answers
What equation describes this variation?
z = kxy
What is the constant of variation?
k = 5
When x = 1 and y = –2, z =
-10
Step by Step Explanation:
With the equation z = kxy and the values for z, x, and y, we can find k.
z = kxy
-75 = (k) (3) (-5)
-75 = (k) (-15)
5 = k
k = 5 (final answer).
To check our work, we just enter all of the values and make sure it adds up.
z = kxy
-75 = (5)(3)(-5)
-75 = 15(-5)
-75 = -75
correct!
Do the same to find the answer for the next part to get -10.

I don’t know what to do
Answers
Answer:
okay so, everytime you see anything that says "a number", that will automatically mean that there is a number in the equation that u dont know, so instead of putting a random number in its place, you put an "exponent" aka a letter like "x" for example. so it says, 12 is the sum of a "number" and 3, that means 3 plus a number gives u 12, you would have to make an equation to find the "number" so the equation would be "3 + x = 12".

4. (5 x 3) x 2 = 5 x (3 x 2) is an example of which property?
A) Commutative Property for Addition
B) Associative Property for Multiplication
O C) Distributive Property for Multiplication
D) Commutative Property for Multiplication
Answers
Answer:
B, Associative property for multiplication
Step-by-step explanation:
Commutative property means the numbers can be multiplied in any order, so the (5 x 3) x 2 could be written as 3 x 5 x 2 and would be the same.
Associative property deals more with groupings of terms/numbers. Since the order of the numbers stayed the same, and the parentheses are moved, this is an example of the associative property.

A scale model of a rectangular building lot measures 7feet by 5 feet. If the actual house will be built using a scale factor of 12 what is the area of the actual building lot
Answers
Step-by-step explanation:
Length of the rectangular building = 7 feet
Width of the rectangular building = 5 feet
Now, The building is made with a scale factor of 12
So, Actual length of the rectangular building = 84 feet
Actual width of the rectangular building = 60 feet
Now, Actual area of the rectangular building = Length × Width
⇒ Actual area of the rectangular building = 84 × 60
⇒ Actual area of the rectangular building = 5040 feet²

2. The ratio of the angle measures in a
triangle is 1:12:17. What is the measure of
smallest angle?
Answers
Answer:
6 degrees
Step-by-step explanation:
x + 12x + 17x = 180
x = 6
The angles are 6 : 72 : 102 so the smallest is 6 degrees.
Answer:
sum of all angles = 180
given angle 1 X., 12 X, 17 X
SO 1 X + 12 X + 17 X= 180
13 X+17 X =180
30 X = 180
X=180\30
X =6
ANS =6
HOW; PUT X = 6 APPLY TO 1 X., 12 X, 17 X
1 X=1×6= 6
12X = 12×6 =72
17 X = 17 ×6 =102
