The standard deviation is 2.08.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
We have the data,
X : 0 1 2 5 10
P(X) : 0.4 0.2 0.2 0.1 0.1
CF : 0.4 0.6 0.8 0.9 1
Sum of fx = 2.5
Mean = 2.5
Deviation X = -2.1 -2.3 -2.1 -2 -1.5
X² = 4.41 5.29 4.41 4 2.25
fX² = 1.764 1.058 0.882 0.4 2.225
Now, standard deviation
= √4.329/1
= 2.08

number multiplied by a fraction is not always smaller than the original number. Explain this and give at least two examples to support your thinking.
Answer:
Sometimes, fractions can be written in 'improper' form, meaning that the top number (numerator) is bigger than the bottom number (denominator). So anything multiplied by a fraction like this will give a bigger number.
For example:
5 × 2/1 = 10
10 x 10/1 = 100
Step-by-step explanation:
Answer:
Step-by-step explanation:
There are two cases where this is true. When the fraction has the same numerator and denominator, or when the numerator is much larger than the denominator.
[tex]2*\frac{4}{4}=2[/tex]

A forest has 6500 trees.
The trees are beech or maple.
number of beech : number of maple = 1.6:1
(a) What fraction of the trees are beech?
Answer:4000
Step-by-step explanation:
Given
There are a total of 6500 trees
The ratio of beech and maple is [tex]1.6:1[/tex]
So, no of beech are [tex]\frac{1.6}{2.6}\times 6500=4000[/tex]
no of maple are [tex]\frac{1}{2.6}\times 6500=2500[/tex]

What are the zeros of f(x) = x2 + x - 12?
O A. x= -4 and x = 3
O B. x=-2 and x = 6
O C. =-3 and x = 4
O D. X=-6 and x = 2
Answer:
(x+4)(x-3) or A
Step-by-step explanation:
I'm going to assume that you meant to write x² and not x2
which means we have
x²+x-12
and we need to factor this
to do this we need two numbers that add up to 1 (b) but mulitply to -12 (a*c)
our two numbers are
4, -3
Which means the answer is
(x+4)(x-3)

If a/b=b/c,then what is b²?
Given:
The equation is
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
To find:
The value of [tex]b^2[/tex].
Solution:
We have,
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
On cross multiplication, we get
[tex]a\times c=b\times b[/tex]
[tex]ac=b^2[/tex]
[tex]b^2=ac[/tex]
Therefore, the value of [tex]b^2[/tex] is [tex]ac[/tex].

The number of peach trees in the orchard is directly proportional to
the number of apple trees. When Farmer Bob planted 40 peach
trees, he planted 120 apple trees. Everything was killed in the
drought and he's starting anew. How many apple trees will he
need to plant if he plants 500 peach trees?
Answer:
there was a difference between the 40 and 120 which was 80 so if there are 500 peach trees he would need to plant 580 because you add the difference to the total. The answer is 580 apple trees

Can someone help find X on the Triangle plssss
Answer:
x = 128°
Step-by-step explanation:
Its an isosceles triangle, so it has 2 two sides of equal length. and from here we can say that it has two angles that are the same, 26° and 26° we know that in a triangle there are 180° in total so we add up the two angles we know 26+26=52 and subtract it by 180 which equals 128°
