At a sleep over, six friends were talking about the number of hours of sleep they usually get each night. Five of them said: 12,9,4,8, & 7 hours. The sixth friend said, “ the average of our sleep hours is 9, so how many hours do I sleep ?
Answer:
So average of a set of values is the sum of given values divided by the number of values
So, in this case the given values are 12, 9 , 4 , 8 ,7 and x (letting the 6th friend's time be x)
so the average will be:
(12 + 9 + 4 + 8 + 7 + x)/6 = 9
40 + x = 54
x = 54 - 40
x = 14 hours

Why is the interest rate of a loan one of the most important things to consider when shopping around for loans?
a.
The interest rate should be ignored, because there’s nothing a consumer can do to change it.
b.
The interest rate is essentially how long you have to pay off your loan, and the shorter the better.
c.
The interest rate can drastically change the total amount paid to the lender, in the case of mortgages, up to thousands of dollars.
d.
The interest rate does not change, even between banks, so choosing the right time to borrow is essential.

C

Answer:
please look at detailed answers below
Step-by-step explanation:

Emily has some $5 bills and $10 bills she has 15 bills she has $120 how many $5 bills does she have
Step-by-step explanation:
Let F = The number of $5 bills and T = the number of $10 bills. She has 15 bills total, so:
F+T = 15
T = 15-F
She has $120 total:
$120 = ($5)*F + ($10)*T
$120 = $5*F + ($10)*(15-F) [Substitute 15-F in place of T]
120 = 5F + 150 - 10F
-30 = -5F
6 = F
Check:
T= 15-F = 15=6 = 9
$120 = ($5)*6 + ($10)*9
$120 = $30 + $90
$120 = $120

Step-by-step explanation:
The distance between two points on a square grid is the root of the sum of two squares, or it is an integer. That is, the non-integer values must be the root of a 2-element subset of the set of squares: {1, 4, 9, ...}, possibly with repeated values.
The possible sums less than 9 are {2, 5, 8}.
The distances √2, √4=2, and √5 can be drawn on a grid. The others listed in these problems (√3, √6, √7) cannot.

Additional comment
In general, the length of any square root can be constructed with compass and ruler. That isn't the question here. For this, we're confined to distances between grid points.
Determine the measures of the marked angles in the figure shown.
The measures of the marked angles in the figure are:
x = 0.8°
6x + 8° = 12.8°
x + 12° = 12.8°
How do we calculate?We have that:
x + 12° and 6x + 8°.
We equate the expression: 6x + 8° = x + 12°
We then solve for x:
6x - x = 12° - 8°
5x = 4°
We then divide both sides by 5:
x = 4° / 5
x = 0.8°
We get the measure of the marked angle for
6x + 8°:
6(0.8°) + 8° = 4.8° + 8° = 12.8°
We also get the measure of the marked angle as:
x + 12°:
0.8° + 12° = 12.8°
In conclusion, an angle is formed when two straight lines or rays meet at a common endpoint.

Exercise 12.1.1: Coin flips and events. About A coin is flipped four times. For each of the events described below, express the event as a set in roster notation. Each outcome is written as a string of length 4 from {H, T}, such as HHTH. Assuming the coin is a fair coin, give the probability of each event. (a) The first and last flips come up heads. (b) There are at least two consecutive flips that come up heads. (c) The first flip comes up tails and there are at least two consecutive flips that come up heads.
Answer:
a \(Pr = 0.25\)
b \(Pr = 0.50\)
c \(Pr = 0.1875\)
Step-by-step explanation:
Given
\(n = 4\) --- number of times
\(r = 2\) --- faces of a coin
First, is to determine the sample size.
This is calculated as:
\(Size =r^n\)
\(Size =2^4\)
\(Size =16\)
Solving (a): First and last slip is head
This event is represented as:
\(E=\{HHHH, HHTH, HTHH, HTTH\}\)
The probability is calculated as:
\(Pr = \frac{n(E)}{Size}\)
\(Pr = \frac{4}{16}\)
\(Pr = 0.25\)
b) At least 2 consecutive flips that is heads.
This event is represented as:
\(E=\{HHHH,HHHT,HHTH,HHTT,THHH,THHT,HTHH,TTHH\}\)
The probability is calculated as:
\(Pr = \frac{n(E)}{Size}\)
\(Pr = \frac{8}{16}\)
\(Pr = 0.50\)
c) First is tail and at least 2 consecutive flips is head.
This event is represented as:
\(E=\{THHH,THHT,TTHH\}\)
The probability is calculated as:
\(Pr = \frac{n(E)}{Size}\)
\(Pr = \frac{3}{16}\)
\(Pr = 0.1875\)

Given information: $\sf\:\csc(x) = 8$, $90° < x < 180° \\$
To find $\sf\:\sin(\frac{x}{2}) \\$, $\sf\:\cos(\frac{x}{2}) \\$, and $\sf\:\tan(\frac{x}{2}) \\$:
Step 1: Rewrite the given information:
$\sf\:\csc(x) = \frac{1}{\sin(x)} = 8 \\$
Step 2: Solve for $\sf\:\sin(x) \\$:
$\sf\:\sin(x) = \frac{1}{8} \\$
Step 3: Use the half-angle identity for $\sf\:\sin(\frac{x}{2}) \\$:
$\sf\:\sin(\frac{x}{2}) = \pm \sqrt{\frac{1 - \cos(x)}{2}} \\$
Since $\sf\:90° < x < 180°$, $\sf\:\cos(x)$ will be negative, so we take the positive square root:
$\sf\:\sin(\frac{x}{2}) = \sqrt{\frac{1 - \cos(x)}{2}} \\$
Step 4: Find $\sf\:\cos(x)$ using the Pythagorean identity:
$\sf\:\sin^2(x) + \cos^2(x) = 1 \\$
Substituting $\sf\:\sin(x) = \frac{1}{8} \\$:
$\sf\:(\frac{1}{8})^2 + \cos^2(x) = 1 \\$
$\sf\:\frac{1}{64} + \cos^2(x) = 1 \\$
$\sf\:\cos^2(x) = 1 - \frac{1}{64} \\$
$\sf\:\cos^2(x) = \frac{63}{64} \\$
Taking the square root of both sides:
$\sf\:\cos(x) = \pm \sqrt{\frac{63}{64}} \\$
Since $\sf\:90° < x < 180°$, $\sf\:\cos(x)$ will be negative, so we take the negative square root:
$\sf\:\cos(x) = -\sqrt{\frac{63}{64}} \\$
Step 5: Use the half-angle identity for $\sf\:\cos(\frac{x}{2})$:
$\sf\:\cos(\frac{x}{2}) = \pm \sqrt{\frac{1 + \cos(x)}{2}} \\$
Since $\sf\:90° < x < 180°$, $\sf\:\cos(x)$ will be negative, so we take the negative square root:
$\sf\:\cos(\frac{x}{2}) = -\sqrt{\frac{1 + \cos(x)}{2}} \\$
Step 6: Find $\sf\:\tan(\frac{x}{2}) \\$ using the identity $\sf\:\tan(\frac{x}{2}) = \frac{\sin(\frac{x}{2})}{\cos(\frac{x}{2})} \\$:
$\sf\:\tan(\frac{x}{2}) = \frac{\sqrt{\frac{1 - \cos(x)}{2}}}{-\sqrt{\frac{1 + \cos(x)}{2}}} \\$
Simplifying:
$\sf\:\tan(\frac{x}{2}) = -\sqrt{\frac{1 - \cos(x)}{1 + \cos(x)}} \\$
Therefore, the values are:
$\sf\:\sin(\frac{x}{2}) = \sqrt{\frac{1 - \cos(x)}{2}} \\$
$\sf\:\cos(\frac{x}{2}) = -\sqrt{\frac{1 + \cos(x)}{2}} \\$
$\sf\:\tan(\frac{x}{2}) = -\sqrt{\frac{1 - \cos(x)}{1 + \cos(x)}} \\$
Please note that the sign of the values may change depending on the actual value of $\sf\:\cos(x)$, which is negative in this case.

write a definite integral that represents the area of the region. (do not evaluate the integral.) y1
The definite integral represents the area of the region ∫(x²-3x)dx.
The definite integral is the region beneath the curve of y1 = x2 - 3x between its first intersection with y2 = 0 and its subsequent intersection with y2 = 0. The curve looks like this:
In order to find their intersection, we equalize them:
x2 - 3x = 0
x(x - 3) = 0
x = 0 and x = 3.
Thus, the integral is:
∫(x²-3x)dx
The area lies below the x-axis, hence the result will be negative (see graph). I would argue that we should take this integral's absolute value in order to arrive at the correct answer for the region's area as we are asked to calculate it. Just place absolute value indications all around the integral.

Answer:
Dustin Earns $14,000 in a year but in the question, we are given the salary of a month
Monthly salary of dustin:
14000 / 12 = $1,166 (approx)
Hence,
The actual monthly salary of Dustin is $1166, excluding the commissions
For a specific month, the salary of Dustin including the commissions is $2,400
Money earned in commissions:
Salary earned - Actual monthly salary
2400 - 1166 = $1,234
We are given the sales of Dustin for that specific month = $ 18,000
Hence, Dustin Earned a commission of $1,234 for sales of $18,000
Commission rate of Dustin:
Commission Earned * 100 / Sales made
1234 * 100 / 18000
6.856 %
Therefore, the commission rate of Dustin is 6.856%
6 minutes 20 seconds into seconds.
Answer:
380 seconds

Convert 6 minutes to seconds by multiplying 6 times 60, because there are 60 seconds per minute.
6 x 60 = 360
Now add the 20 seconds.
360 + 20 = 380

a) sin A = 0.6018
b) cos B = 0.9205
c) tan C = 0.0349
Answer:
Sure, I can help with that! Here are the steps to solve each problem:
a) Since sin A = 0.6018, we can use the inverse sine function (sin^-1) to find the measure of angle A. Taking the inverse sine of 0.6018 gives us 37.19 degrees rounded to the nearest degree.
b) Since cos B = 0.9205, we can use the inverse cosine function (cos^-1) to find the measure of angle B. Taking the inverse cosine of 0.9205 gives us 23.06 degrees rounded to the nearest degree.
c) Since tan C = 0.0349, we can use the inverse tangent function (tan^-1) to find the measure of angle C. Taking the inverse tangent of 0.0349 gives us 2.00 degrees rounded to the nearest degree.
