You have found the following ages (in years) of all 5 porcupines at your local zoo:
16,10,5,7,13
What is the average age of the porcupines at your zoo? What is the standard deviation? Round your answers to the nearest tenth.
Answers
Answer:
Average is 10.2 standard deviation is 3.4
Step-by-step explanation:
To find the average age, add all the value together then divide by the amount added. (5 + 7 + 10 + 13 + 16) / 5
Standard deviation is average distance from average of each number. 10.2-5, etc…
The average age of the porcupines at the zoo is 10.2 and the standard deviation is 4
What is Standard Deviation?
The term "standard deviation" (or "") refers to a measurement of the data dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Standard Deviation is calculated by
Each number's deviation from the mean must be determined, and then squared.Next, add up all of these values.Divide the result by the quantity of numbers.Then calculate its square root.Given data ,
The set of ages of porcupines in zoo be S = { 16 , 10 , 5 , 7 , 13 }
The average of these numbers in set S is the sum of all the numbers divided by the number of elements in the set
So , Average age of the porcupines = ( 16 + 10 + 5 + 7 + 13 ) / 5
= 51 / 5
= 10.2
Therefore , the average age of the porcupines at the zoo is 10.2
The standard deviation is calculated by
Step 1 : Each number's deviation from the mean must be determined, and then squared.
( 16 - 10.2 )² + ( 10 - 10.2)² + ( 5 - 10.2 )² + ( 7 - 10.2 )² + ( 13-10.2 )²
= ( 5.8 )² + ( -0.2 )² + ( -5.2 )² + ( -3.2 )² + ( 2.8 )²
= 33.64 + 0.04 + 27.04 + 10.24 + 7.84
= 78.8
Step 2 : Divide the result by the quantity of numbers.
78.8 / 5
= 15.76
Step 3 : Then calculate its square root.
√15.76
= 3.96
≈ 4
Hence , the standard deviation is 4

Answer:
A. 2^11
Step-by-step explanation:
(They are basically asking what's 2^4 × 2^7, but with more words.)
I usually do each exponent individually:
2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)
2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128
Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.
BUT, you can also:
(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)
2^4 × 2^7
4 + 7 = 11
2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).
Hope this helps friend :)

Nik needs to estimate how many books will fit in a bin. Each book is 0.75 feet tall, 0.75 feet wide, and 0.25 feet thick. The bin is 4 feet wide, 4 feet tall, and 4 feet deep. Based on volume only, about how many books will fit in the bin?
Answers
Step-by-step explanation:
first you find the volume of a bin.
that is multiplication of 3 dimensions given.
4*4*4=64 cubic feet...
now volume of books..
0.75*0.75.0.25=0.14 cubic feet
now the number of books that will fit the bin=volume of bin/volume of books
64/0.14=455
455 books
We want to see how many books can fit in a bin, given that we know the dimensions of the books and the bin. We will see that 457 books can enter in the bin.
Remember that the volume of a rectangular prism of length L, width W, and height H is just given by:
V = L*W*H
Here we know that each book is:
0.75ft by 0.75ft by 0.25ft
Then the volume of a single book is:
V = 0.75ft*0.75ft*0.25ft = 0.14 ft^3)
While the bin is 4ft by 4ft by 4ft, thus its volume is:
V ' = 4ft*4ft*4ft = 64ft^3
The number of books that fit in the bin is given by the quotient between the bin's volume and the book's volume:
N = (64ft^3)/(0.14 ft^3) = 457 books.

Step-by-step explanation:

Answer:
y = 3x +5
Step-by-step explanation:
The given form of the equation for a line is "slope-intercept" form. In order to use it, you need to know the slope of the line, and its y-intercept.
The y-intercept is where the line meets the y-axis. Here, that is halfway between 4 and 6, so we estimate the value to be b = 5.
The slope is the rise divided by the run. For x=1, the line has a point at (1, 8). That is 3 units above and 1 unit right of the point on the y-axis. Then the slope is ...
m = rise/run = 3/1 = 3
For a slope of 3 and a y-intercept of 5, the equation of the line is ...
y = mx +b . . . . . . slope m, y-intercept b
y = 3x +5
