Answer:
12. C
13. D
Step-by-step explanation:
12. For interest r on principal P compounded n times per year for t years, the account balance is ...
A = P(1 +r/n)^(nt)
For P=800, r=0.05, n=365, t=6, this becomes ...
A = 800(1 +0.05/365)^2190 . . . . matches choice C
Note: if you're familiar with the formula, you will notice choice C is the only one with 'n' in the right place.
__
13. The form of an exponential function is ...
y = a·b^x . . . . . . . . where 'a' is the initial value, and 'b' is the growth factor
The form of the equation eliminates choices A and B.
Here, the initial value is 1.87, eliminating choice C.
Matching the problem statement to the form of the exponential function we see that the equation of choice D is appropriate.
Consider the polynomial
Answer:
C
Step-by-step explanation:
1. The third term has an exponent of 1.
2. A constant is the number with no variable.

Find the indicated side of the
right triangle.

45°
х
y = [?]
Answer:
y = 9√2
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
y² = 9² + x²
By the property of isosceles triangle,
Two angles of the right triangle are equal in measure, opposite sides of these equal angles will be equal in measure.
Therefore, x = 9
y² = 9² + 9²
y² = 81 + 81
y² = 162
y = √162
y = 9√2

y = (2/3)x + 19/3
Let me know if there are any parts of the process you do not understand.
Step-by-step explanation:
First you need to know what slope is, if you do not let me know and I can explain it in depth.
Now, you can determine if a line is parallel or perpendicular by its slope. parallel has the same slope and perpendicular has the negative reciporical, which basically means negative 1 divided by the slope.
So if you slope was 3 perpendicular would be -1/3. if the slope is a fraction you can just flip the fraction and make it negative. so if the slope is -2/3 a perpendicular slope would be 3/2, making a negative number negative makes it positive.
Now you start with 2x - 3y = 12. To find the slope I like putting it in slope intercept form. basically somethign that looks liek y = mx + b. to do that just use algebra on what you have to get y by itself. here is how I would do that.
2x - 3y = 12 first subtract 2x from both sides
-3y = 12 - 2x Now divide both sides by -3
y = 12/-3 - (2x)/3 Now simplify
y = -4 + 2/3 x Now rarrange to make it look like I said, basically you want the x first.
y = 2/3 x - 4
There, so the slope is 2/3. A parallel line will have the same slope.
To make the equation of a line you want one point and the slope. Well we have that, the point is (-2,5) and the slope is 2/3.
To find a line you set up the point slope form. that is y - y1 = m(x - x1) where m is the slope and x1 and y1 are the coordinates of the point you need. I will plug all that in.
y - y1 = m(x - x1)
y - 5 = (2/3)(x - (-2)) Now solve
y - 5 = (2/3)x + 4/3
y = (2/3)x + 19/3
So that is the equation of a line parallel to 2x - 3y = 12 that passes through (-2, 5)
A ship’s captain sights the top of a 200 foot cliff at a 17° angle of elevation. How far is the ship from the base of the cliff? Round to the nearest foot.
Answer:
654 ft
Step-by-step explanation:
in this case you have a SOH-CAH-TOA problem.
we need Adjacent and opposite so we use tan
tan (17) = O/A
tan (17) = 200ft / x
x = 654.17 ft
to the nearest foot = 654 ft

The distance that represent the ship from the base of the cliff should be considered as the 654 ft.
Calculation of the distance:Since
A ship’s captain sights the top of a 200 foot cliff at a 17° angle of elevation.
So the following formula should be applied
[tex]tan (17) = O/A\\\\tan (17) = 200ft / x[/tex]
x = 654.17 ft
= 654 ft
hence, The distance that represent the ship from the base of the cliff should be considered as the 654 ft.

Find the probability of drawing a 10 from a standard deck
of 52 cards,
Answer:
4/52 or 1/13 (simplified)
Step-by-step explanation:
There are 4 "10's" in a pack.
This means you have the chance to pick 4 10's.
So out of 52 cards, you can get 4.
4/52 -> Which can be simplified to 1/13.
This is the probability of getting a 10 (once) in a standard deck of cards.
The probability of drawing a 10 from a standard deck of 52 cards is 1/13.
Number of 10's in a standard deck of 52 cards =4
Total cards =52
What is probability?Probability is the measurement of the possibilities of events.
P(event) =Favorable outcomes/ Total possible outcomes
Here, Favorable outcomes =4
Total possible outcomes =52
P(10) =4/52
P(10) =1/13
So, the probability of drawing a 10 from a standard deck of 52 cards =1/13
Thus, the probability of drawing a 10 from a standard deck of 52 cards is 1/13

Answer:
A. 6
Step-by-step explanation:
The wording "set A and set B" means you're interested in elements that belong only to both. In your diagram, that is Region II. There are 6 elements that belong to A and B.
AB = 6
_____
Additional comment
"A and B" is also called the "intersection" of the two sets: A ∩ B.
The number you have chosen is the number in Regions I, II, and III. That is the set of elements that belong to A or B. You have identified the "union" of the two sets: A ∪ B. (It might also be represented as A+B.)

Determine whether the random, variable is discrete or continuous.
In each case, state the possible values of the random variable.
(a) The number of people in a restaurant that has a capacity of 100
(b) The square footage of a house.
(a) Is the number of people in a restaurant that has a capacity of 100 discrete or continuous?
A. The random variable is discrete. The possible values are 0≤x≤ 100.
B. The random variable is continuous. The possible values are 0≤x≤ 100.
C. The random variable is discrete. The possible values are x= 0, 1, 2... 100
D. The random variable is continuous. The possible values are x= 0, 1, 2... 100
b) Is the square footage of a house discrete or continuous?
A. The random variable is discrete. the possible values are a > 0
B. The random variable is discrete. The possible values are a = 1, 2, 3...
C. The random variable is continuous. The possible values are a > 0.
D. The random variable is continuous. The possible values are a = 1,2, 3,
A discrete variable is a variable that can be counted. It has a finite amount of values. The number of people in the restaurant is finite. It cannot exceed 100. At any point in time when you count the number of people in the restaurant and it would be between 0 - 100
A continuous variable has an infinite amount of values it can take on. The square footage of a house can be of any size. there is no limit to the size of a house. it can be as small or big as the architect's imagination allows.

One hundred sixty people who suffer from painful diabetic neuropathy have volunteered to participate in a study. Eighty are selected at random and are given the drug gabapentin, which, although originally intended to prevent epileptic seizures, has properties that may make it useful to alleviate neuropathy. The remaining participants are given a placebo. A neurologist evaluates the symptoms of all volunteers after two months to determine if there has been substantial improvement in the severity of the symptoms.
Does the use of volunteers make this study invalid?
a. yes, because of volunteer bias no, because blocking was used.
b. yes, because there is no way to determine the effect of gabapentin on people that do not have symptoms of neuropathy.
c. no, because the subjects are randomly assigned to treatment groups.
Answer:
C. No, because the subjects are randomly assigned to treatment groups
Step-by-step explanation:
We are told that 80 people are selected at random and are given the drug gabapentin.
Also that the remaining people are given the placebo.
This means that they are randomly assigned treatment groups and so it is a completely randomized block design and as such the use of volunteers doesn't make it invalid.

Answer:
-1 is the correct answer
Step-by-step explanation:
Move that many points on the number line
The position of B on number line is at - 1.
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Point A is shown on the the number line below.
And, Another point, B , is to be placed on the number line and will be 2 1/2 unit from point A.
Now,
Since, The position of Point A = 1 1/2
And, Another point, B , is to be placed on the number line and will be 2 1/2 unit from point A.
So, The point B = 1 1/2 + (-2 1/2)
= 3/2 - 5/2
= - 2/2
= - 1
Thus, The position of point B = - 1
