The county health inspector will select a random sample of 4 community swimming pools in the county to investigate the pH levels. (b) Describe the sampling distribution of the sample mean for samples of size 4.
Using the Central Limit Theorem, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution is normal, with mean [tex]\mu[/tex] and standard deviation [tex]0.5\sigma[/tex].
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
Hence, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], and with the sample size of n = 4, the mean remains the same while the standard deviation is given by:
[tex]s = \frac{\sigma}{\sqrt{4}} = 0.5\sigma[/tex]

A lawn sprinkler sprays water 4 feet in all direction as it rotates.
Find the area of the lawn the sprinkler covers. Use 3.14 for pi.
Answer:
50.24 ft^2
Step-by-step explanation:
The radius of the circle in which the lawn sprinkler sprays water is 4 feet.
The formula to find the area of a circle is [tex]\pi r^2[/tex], where r = radius and π, in this case, is 3.14.
3.14 × 4^23.14 × 1650.24 ft^2Therefore, the answer is 50.24 ft².

(01.05 MC)Which fraction is equivalent to 2/-6
• -2/6
• 2/6
• -2/-6
• 6/2
Answer:
-2/6
Step-by-step explanation:
the negative is applied to the entire fraction so it doesnt matter if its at top or bottom
-2/6
Step-by-step explanation:
the fraction which is equivalent to is -2/6
cuz where are the minus sign is on the numerator or the denominator is still gives the same output
SO 2/-6
=> - 0.333
Even
-2/6
=> - 0.333Marie has bought a plant which she needs to transfer from its cylindrical pot to the ground. The pot has diameter 10 cm and is 21 cm high. Marie needs to dig a hole 4cm wider and 5cm deeper than the pot. She then inserts the plant and fills in the rest of the hole with extra soil. (i) Calculate the volume of the hole Marie needs to dig. (ii) Before inserting the plant, Marie fills the hole with water. How much water will she need, assuming none of it soaks away? (iii) Marie is planning to paint the outside of the cylindrical pot excluding the top and bottom. Calculate the area to be painted
Using known formulas for cylinders, we will get:
i) 4,000.36 cm^3ii) 4,000.36 cm^3iii) 1,142.96 cm^2.Working with cylinders:
We know that the pot has a diameter of 10cm and a height of 21 cm, and the hole must be 4 cm wider (so the diameter is 14cm) and 5 cm deeper (so the height is 26cm).
i) The volume of a cylinder of radius r and height H is given by:
V = pi*r^2*H
Where pi = 3.14, and the radius is half the diameter, so we have:
r = 14cm/2 = 7cm.
Then the volume is:
V = 3.14*(7cm)^2*26cm = 4,000.36 cm^3
ii) To fill a volume of 4,000.36 cm^3, you need 4,000.36 cm^3 of water.
iii) The curve surface of a cylinder is given by:
S = 2*pi*r*H
Remember that:
r = 7cm
H = 26cm.
Replacing that we get:
S = 2*3.14*7cm*26cm = 1,142.96 cm^2
So se must paint an area of 1,142.96 cm^2.

Use the drawing tool(s) to form the correct answers on the provided graph.
Consider the given function.
h(x) = (x + 1)^2 - 4 plot the intercept
Answer:
The answers are in the images below.
Step-by-step explanation:
The graph of the function h(x) = (x + 1)² - 4 is given in attachment and it is a parabola.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given function is h(x) = (x + 1)² - 4
h of x equal to x plus one whole square minus four.
We have to draw the graph of function h(x) = (x + 1)² - 4
Let us find some points of the graph by considering the function.
When x=0,
y=-3
When x=1
y=0
when x=2
y=5
when x=3
y=12
Now let us plot these points on the graph, we get a parabola as in attachment.
Hence, the graph of the function h(x) = (x + 1)² - 4 is given in attachment and it is a parabola.

C. there is no solution
Step-by-step explanation:
Add 6 to both sides:
2x- 6 + 6=2x +5 + 6
Simplify equation above:
2x=2x+11
Subtract 2x from both sides:
2x - 2x=2x+11 -2x
Simplify equation above:
0 = 11
The sides are not equal, Therefore there is no solution :(
Solve the system of linear equations.
6x+2y=16
2x - y = 2
Do I put into point slope form??
Answer:
The simple answer, "Yes"
Answer:
Point slope form of the equations:
y = -3x + 8
y = 2x - 2
Solution to the system of equations:
(x, y) ==> (2, 4)
Step-by-step explanation:
6x + 2y = 16
2x - y = 2
6x + 2y = 16
2(2x - y = 2) ==> 4x - 2y = 4
6x + 2y = 16
4x - 2y = 4
10x = 20
/10 /10
x = 2
Now, we solve for y:
6x + 2y = 16
6(2) + 2y = 16
12 + 2y = 16
-12 -12
2y = 4
/2 /2
y = 2
(x, y) ==> (2, 2)
Point-slope forms:
6x + 2y = 16
-6x -6x
2y = -6x + 16
/2 /2
y = -3x + 8
2x - y = 2
-2x -2x
-1y = -2x + 2
/-1 -1
y = 2x - 2
