This Bar Chart shows how many days it took for 12 corn seedlings to emerge.
What is the range of this set of data?
The Range of the given set is 5.
We have been given Bar Chart that shows how many days it took for 12 corn seedlings to emerge.
We know that the Range of data set is the difference between the smallest and largest values
It is a measure of the spread or variability of the data set.
The highest point is 10
The lowest point is 5
The Range = 10 - 5
Range = 5
Therefore, the correct answer is 5.

What is the mean absolute deviation of the data 10, 17, 20, 12, and 16? Round to the nearest whole number
Answer:
3.5
Step-by-step explanation:
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.
Answer:
The answer is 4
[tex]s = \sqrt{\frac{\Sigma^n_i_=_1(x_i-x)^2}{n-1} }[/tex]
Turn the equation into a simpler form
[tex]s = \sqrt{\frac{SS}{n-1} }[/tex]
[tex]s = \sqrt{\frac{64}{5-1} }[/tex]
[tex]s = \sqrt{\frac{64}{4} }[/tex]
[tex]s = \sqrt{16}[/tex]
That said, we know the square root of 16 is 4, so 4 would be your answer.

Find the area of the parallelogram.
Solve for the missing variables. (Geometry)
Step-by-step explanation:
we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.
in other words
h² = p×q
h = height
p, q are the 2 segments of the Hypotenuse.
so, in our case we have
100 = x(x + 21) = x² + 21x
that gives us the following quadratic equation
x² + 21x - 100 = 0
the general solution to a quadratic equating is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 21
c = -100
so,
x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =
= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =
= (-21 ± 29)/2
x1 = (-21 + 29)/2 = 8/2 = 4
x2 = (-21 - 29)/2 = -50/2 = -25
x2 would give us negative lengths for the triangle, which does not make sense.
so, x = 4 is our solution.
that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).

Jared invited his friends over for lunch. He bought a pizza and ate 3/4 of it himself before calling his friends. He called Bob, Matombe, Steve, Owen, and Bill. Now, Jared must divide the 1/4 of the pizza into 5 parts for his friends to eat.
Answer:
Step-by-step explanation:
If 1/4 is divided by 5 we can think about it as 1/4 is a quarter of a whole and we need to divide that quarter in 5 equal parts.
Story Problem:
Alexa has 5 more days to finish reading the ELA book assigned by her teacher. She still has to read 1/4 of the book. What fraction of the book she should read on each of the 5 days to ensure she will be done in time?
(1/4 ) / 5 = (1/4) *(1/5) = 1 / 20
If Alexa reads 1/20 of the book each day she will finish the book in 5 days.
13. An elephant takes 8 steps in 10 seconds. At this rate, how many steps does it take in 4 minutes?
Answer:
192
Step-by-step explanation:
8 steps per 10 seconds
How many steps per 4 minutes?
First, find out how many 10-second intervals there are in 4 minutes.
4 minutes = 240 seconds
240 divided by 10 is 24
24 ten second periods times 8 steps per 10 seconds

Find the area of the composite figure shown to the nearest half unit.
Answer:
Area = 13
Step-by-step explanation:
see image. There's a brick of 8 whole squares on the bottom. Then a layer of 3 whole squares on top of that. There's a 1/2 a square besides the 3. Then on top, there is half of a layer of 3 squares. Half of 3 is 1 1/2.
8 + 3 + 1/2 + 1 1/2
= 8 + 3 + 2

Answer:

Step-by-step explanation:
Area of a triangle
The area of a triangle can be calculated using the formula
A = bh/2 where b = base length and h = height
Finding the area by plugging in the values of the height and base length
Looking at the triangle we can tell that the base length is 8 and the height is 10. ( so b = 8 and h = 10 )
So we have A = bh/2
==> plug in b = 8 and h = 10
A = (8)(10)/2
==> multiply 8 and 10
A = 80/2
==> divide 80 by 2
A = 40
