Once again, consider the data for Fred's caloric intake. 2000 2200 2100 2400 2500 1900 2200 2200 2700 2600 Find the : (enter your answers as numbers) Sample standard deviation (rounded to the nearest hundredth)
Answer:
The sample standard deviation is of 248.19.
Step-by-step explanation:
First we find the sample mean, which is needed to find the sample standard deviation.
Sample mean:
Sum of all values in the sample, divided by the number of values. So
[tex]M = \frac{2000+2200+2100+2400+2500+1900+2200+2200+2700+2600}{10} = 2280[/tex]
Sample standard deviation:
Square root of the sum of the difference squared between each value and the mean, divided by the number of values. So:
[tex]S = \sqrt{\frac{(2000-2280)^2+(2200-2280)^2+(2100-2280)^2+(2400-2280)^2+(2500-2280)^2+(1900-2280)^2+...}{10}} = 248.19[/tex]
The sample standard deviation is of 248.19.

A recent survey showed that 23.3 million adults have cut the cord on cable TV services, a 30% increase fron the previous year. If this trend continues, how many millions if adults can be expected to cut the cord next year?
Answer:
30,290,000 people
Step-by-step explanation:
The question is asking if the trend continues from the PREVIOUS year, so we would find the 30% of 23,300,000
23,300,000/100 = 233,000 = 1%
233,000 x 30 = 6,990,000
23,300,000 = 6,990,000 = 30,290,000
A particle moves along the x-axis with the given acceleration function a(t) = 8t - 6, initial position s(0) = 2, and initial velocity v(0). Find the position function.
Answer:
[tex]s(t) = \frac{4t^3}{3} - 3t^2 + v(0)t + 2[/tex]
Step-by-step explanation:
Relation between acceleration, velocity and position:
The velocity function is the integral of the acceleration function.
The position function is the integral of the velocity function.
Acceleration:
As given by the problem, the acceleration function is:
[tex]a(t) = 8t - 6[/tex]
Velocity:
[tex]v(t) = \int a(t) dt = \int (8t - 6) dt = \frac{8t^2}{2} - 6t + K = 4t^2 - 6t + K[/tex]
In which the constant of integration K is the initial velocity, which is v(0). So
[tex]v(t) = 4t^2 - 6t + v(0)[/tex]
Position:
[tex]s(t) = \int v(t) dt = \int (4t^2 - 6t + v(0)) dt = \frac{4t^3}{3} - \frac{6t^2}{2} + v(0)t + K = \frac{4t^3}{3} - 3t^2 + v(0)t + K[/tex]
The initial position is s(0) = 2. So
[tex]s(t) = \frac{4t^3}{3} - 3t^2 + v(0)t + 2[/tex]
It is known that ARST - AWXY. If RS =18, ST = 25, and TR=11 then which of the following is closest
to the ratio of XY to WX?
(1) 0.44
(3) 2.27
(2) 1.39
(4) 0.72
Answer:
[tex]XY : WX = 1.39[/tex]
Step-by-step explanation:
Given
[tex]RS = 18; ST = 25; TR = 11[/tex]
Required
Which is closest to [tex]XY : WX[/tex]
From the question, we understand that: [tex]\triangle RST[/tex] and [tex]\triangle WXY[/tex] are similar.
This means that, the following sides are similar:
[tex]RS \to WX[/tex]
[tex]ST \to XY[/tex]
[tex]TR \to YW[/tex]
So:
[tex]XY : WX = ST : RS[/tex]
This gives:
[tex]XY : WX = 25 : 18[/tex]
Express as fraction
[tex]XY : WX = \frac{25 }{ 18}[/tex]
[tex]XY : WX = 1.39[/tex] --- approximated

A chord consists of notes that sound good together. the C major chord, starting at middle C, has the following frequencies:
C - 262 Hz
E - 330 Hz
G - 392 Hz
Determine the ratio of the frequency of G to C. Express the answer in a simple integer ratio. (Due to rounding the ratio will be approximate. )
a. 5 to 4
b. 3 to 2
c. 6 to 5
d. 9 to 8
Please select the best answer from choices provided
Answer:
B. 3 to 2
Step-by-step explanation:
I calculated it logically
The ratio of the frequency of G to C is 1.5. So, option b is correct.
What is meant by frequency ?Frequency of a wave is defined as the number of oscillations completed by the wave in one second.
Here,
The frequency of note G, f(G) = 392 Hz
The frequency of note C, f(C) = 262 Hz
The ratio of the frequency of G to C, r = frequency of G/frequency of C
r = f(G)/f(C)
r = 392/262
r = 1.496 approximately r = 1.5
Hence,
The ratio of the frequency of G to C is 1.5

3^3 x 3.14
9 x 3.14 = 28.26
28.26 x 2 = 56.52
2 x 3.14 x 3 = 18.84
18.84 x 10 = 188.4

line f has a slope of -3. what is the slope of the line that is parallel to line f
Answer:
A line parallel has the same slope, so -3
The slope of the line that is parallel to line f is -3.
The given line f has a slope of -3.
We need to find the slope of the line that is parallel to line f.
What are parallel lines slope?The slope of parallel lines. The slope of parallel lines is equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as [tex]m_{1}[/tex], [tex]m_{2}[/tex] then we have [tex]m_{1}=m_{2}[/tex].
So, the slope of the parallel line=-3
Therefore, the slope of the line that is parallel to line f is -3.

Answer:
517.2
Step-by-step explanation:
It has sides you're not seeing so don't forget those.
You need to find the area of the front, back, two sides, and bottom
Front & back:
6*5.2* 1/2
31.2/2 = 15.6 for each
Sides:
27*6 = 162 each
Bottom:
6*27 = 162
162+162+162+15.6+15.6= final answer
Answer: B
Step-by-step explanation:
First, you do 5.2 times 6 divided by two which is 15.6. Now you do 15.6 times two since there are two triangles and get 31.2. Now you do 27 times 6 times two and get 324 + 31.2 = 355.2. Lastly, you do 27 times 6 to get 162. 162+355.2 = 517.2

Answer:
6
Step-by-step explanation:
The interquartile range is calculated by subtracting the first quartile from the third quartile. Box and whisker plots make it pretty easy to find the quartiles. The first quartile is the point where the box starts, and the third is where the box ends. The second is the median/line in the middle of the box.
So for that first box plot on the top, the first quartile is 7, because that's where the box begins. The third quartile is 22 because it's where the box ends.
For the second one, the first quartile is 8 and the third is 17.
To find the interquartile range of each, subtract the first quartile from the third. 22-7 = 15 and 17-8 = 9.
Now to find the difference in the interquartile ranges, subtract 9 from 15. You get 6, so that is the answer :)
- Solve the equation 3 + n = 12
Answer:
n = 9
