Answer:
The z-score corresponding to an observed value of x of 2 is 0.215.
Step-by-step explanation:
We are given that a variable x has the possible observations shown below;
Possible observations of X: -3, -1, 0, 1, 1, 2, 4, 4, 5.
Firstly, we will find the mean and the standard deviation of X, i.e;
Mean of X, (
) = 
= 
= 
= 1.44
Standard deviation of X, (
) = 
= 
= 2.603
Now, the z-score corresponding to an observed value of x of 2 is given by;
z-score = 
= 
= <u>0.215.</u>
You have to find the circumference of both circles.
B= 25.12
Y= 87.92
I think this is right.
Hey there!
Let's solve this equation.
5x+3x-4=10
add the x's
8x-4=10
add 4 to both sides
8x=10+4
8x=14
divide both sides by 8
x=14/8
Reduce the fraction;
x=7/4 (improper fraction)
x=1+3/4 (mixed number)
Hence, the equation has 1 solution.
Hope everything is clear.
Let me know if you have any questions!

shelly sews a blanket that has an area of 170 square feet. it has 30 square blocks each the same size
30 square blocks of same size. We need to find the area of each square block. so we divide 30 from the total are 170
The area of each square = 5.66667 square feet
We know area of square = side ^2
side ^2 = 5.66667
To find side , take square root on both sides
The side of the square of each block = 2 feet
<, > - open circle
≤, ≥ - closed circle
<, ≤ - draw to the left
>, ≥ - draw to the right

We have x ≥ 3
closed circle on number 3 and draw the line to the right
