a)
Add the score and then square the sum.
By using the summation notation we can write the above statement is (Σx)²
b)
Square each score and then add the squared values.
By using the summation notation we can write the above statement is Σx²
Subtract 2 point from each score and then add the resulting values.
By using the summation notation we can write the above statement is Σ(x-2)
Subtract 1 point from each score and square the resulting values. Then add the squared values.
By using the summation notation we can write the above statement is Σ(x-1)²
Answer:
Shape a has 1 order of rotational symmetry and 1 line of symmetry
Shape b has 2 orders of rotational symmetry and 0 line of symmetry
Rotational symmetry is how many times a shape can be rotated and look the same.
Lines of symmetry are how lines can be put through the shape to make it symmetrical or the same on both sides
Answer:P(x<10) =0
Step-by-step explanation:
M =1/μ
M= 1/15 =0.066667
X- Exp (0.066667)
Where: X is the random variable for number of days
P (X<x) = 1 - e^-mx
P(X - x) = 1 - e^-0.06666 x10
P(x<10) = 0
Answer:
(-2,3)
Step-by-step explanation:
I used Desmos to input these 2 equations and then locate the point(s) at which they intersect. Since these are both linear, there will be either 1 solution or none at all, but in this case, there is one solution, and it is at the point (-2,3) which is where the 2 graphs intersect.
Roosters to chickens is 2 to 8
That means where there are 2 roosters, there are 8 chickens.
Simplify the ratio 2:8
The ratio can be simplified to 1:4
So, for 1 rooster, there are 4 chickens.
Now, the question says that if there are 5 roosters, how many chickens will there be?
1 rooster to 4 chickens
5 roosters to ? chickens
We went from 1 rooster to 5 rooster. We multiplied by 5.
To find out how many chickens there are for 5 roosters, multiply 4 chickens by 5.
4 * 5 = 20
Where there are 5 roosters, there will be
20 chickens.
Another way to solve is as follows:

Your final answer is
20 chickens.<span />
