Answer:
hello your question is incomplete attached below is the complete question
answer :
H0 : u = 21.62 ( Null hypothesis )
H1 : u = 21.62 ( alternative hypothesis )
Step-by-step explanation:
Formulating hypothesis that can be used to determine whether the population mean rate at 5 CCF of residential water discharged by U.S public utilities differs from $21.62
H0 : u = 21.62 ( Null hypothesis )
H1 : u = 21.62 ( alternative hypothesis )

What is the solution to the system of equations?
y = -5x + 3
y = 1
9514 1404 393
Answer:
(x, y) = (2/5, 1)
Step-by-step explanation:
Substitute for y and solve for x.
1 = -5x +3
-2 = -5x . . . . . . subtract 3
2/5 = x . . . . . . divide by -5
The solution is (x, y) = (2/5, 1).

Answer:
The bottom left is linear, and its slope is -2.
The bottom left is linear, and its slope is 7.
Step-by-step explanation:
The rate of change is consistent for both, so they are linear. Every time you go up one, the y value increases a certain amount, and it's the same at every point.
On a test, Alice had 80% of the problems right. If she had
20 problems correct, how many questions were on the test?
Show work please
Answer: she would get 100%
Step-by-step explanation: every correct question u get 5 points so 20 * 5 = 100
Answer:
25
Step-by-step explanation:
80% = 0.80
0.80x = 20
0.80x/0.80 = 20/0.80
x = 25
So there was 25 questions on the test
How many solutions does the system of equations below have?
y= 3x + 4
2y -8 = 6x
Answer:
infinitely many solutions (infinite solutions)
Step-by-step explanation:
2y - 8 = 6x
+8 +8
-------------------------------
2y = 6x + 8
[tex]\frac{2y}{2}[/tex] = [tex]\frac{6x}{2}[/tex] + [tex]\frac{8}{2}[/tex]
-------------------------------
y = 3x + 4
Because 3x + 4 = 3x + 4, there are infinitely many solutions to this system of equations. This is because they're the exact same equations. Any substitution for x will give you a true statement to y when compared to the other equation.
What's the distance of (-2, 0), (3, -5) plz help thank you
Answer:

Step-by-step explanation:
Answer:
The Distance Formula itself is actually derived from the Pythagorean Theorem which is {a^2} + {b^2} = {c^2}a

+b
2
=c

where cc is the longest side of a right triangle (also known as the hypotenuse) and aa and bb are the other shorter sides (known as the legs of a right triangle).
The very essence of the Distance Formula is to calculate the length of the hypotenuse of the right triangle which is represented by the letter cc.
a green right triangle with hypotenuse c (distance between two red dots) and legs a and b.
That’s why we can claim that the idea of the Distance Formula is borrowed and derived from the Pythagorean Theorem. If you want to see how the Distance Formula is derived from the Pythagorean Theorem, please check out my lesson on How to Derive the Distance Formula.
Which two estimates is the quotient 345÷8 between
Need help I need to do this right now!
Answer: Okay, well first lets find the quotient 345 ÷ 8:
It is 43. 125, but we're going to simplify it to 43
Now this is the really easy part, so lets find a number greater than 43, which would be 44.
Now that we have that, we need to find a decimal that's lower than 43, which would be 42.
So our numbers would be 44 and 42.

Suppose that a random sample of size 100 is to be selected from a population with mean 50 and standard deviation 8. What is the probability that a sample mean will be greater than 50.8? Round your answer to three decimal places.
Answer:
0.159
Step-by-step explanation:
Given that:
Sample size (n) = 100
Population mean(pm) = 50
Standard deviation (s) = 8
Probability that Sample mean (m) will be greater Than 50.8
Using the relation :
(sample mean - population mean) / (standard deviation /sqrt(n))
P(m > 50.8)
Z = (50.8 - 50) / (8/ sqrt(100))
Z = 0.8 / (8/ 10)
Z = 0.8 / 0.8
Z = 1
P(Z > 1) = 0.15866 ( Z probability calculator)
Hence,
P(Z > 1) = 0.159 ( 3 decimal places)
The probability that a sample mean will be greater than 50.8 is P(Z > 1) = 0.159.
Given that,
Suppose that a random sample of size 100 is to be selected from a population with a mean of 50 and a standard deviation of 8.
We have to determine,
What is the probability that a sample mean will be greater than 50.8?
According to the question,
Sample size (n) = 100
Population mean(pm) = 50
Standard deviation (s) = 8
The probability that Sample mean (m) will be greater than 50.8.
Therefore,
[tex]\dfrac{(sample \ mean - population \ mean) \times \sqrt{n}}{standard \ deviation}[/tex]
Where P(m > 50.8)
[tex]Z = \dfrac{50.8 - 50 \times \sqrt{100}}{8}\\\\Z =\dfrac{ 0.8 \times 10 }{8}\\\\Z = \dfrac{0.8 }{0.8}\\\\Z = 1[/tex]
P(Z > 1) = 0.15866 ( Z probability calculator)
Hence, The probability that a sample mean will be greater than 50.8 is P(Z > 1) = 0.159.

Answer:
An adult cosigner reason been that he is under 18
Step-by-step explanation:
Based on the information give, since we were told that he is 16 years old in which he want to open a savings account which means that he will need to bring AN ADULT COSIGNER to the local bank branch in order to start an account reason been that he is under 18.
Hence, AN ADULT COSIGNER can either be his parent, his close family member or his friend who will stand for him because he is under 18.

Answer:
G. [tex]\frac{6}{3}[/tex] = [tex]\frac{h}{18}[/tex]
Step-by-step explanation:
Hey, I'm not very sure but I just want to give it a try, hopefully it helps. If not, I'm so sorry.
They said the line segment creates two similar triangles. This means that 18 is like the base of the triangle (just like how 3 is the base of the smaller triangle) and h is like the height of the triangle (just like how 6 is the height of the triangle). Thus, if you put it as a fractional proportion way, it would be:
[tex]\frac{6}{3}[/tex] = [tex]\frac{h}{18}[/tex]
(6 = h and 3 = 18 but in different sizes, proportion stays the same)
You can even try to solve h using [tex]\frac{6}{3}[/tex] = [tex]\frac{h}{18}[/tex] .
2 = [tex]\frac{h}{18}[/tex]
h = 2 × 18
h = 36

A square and regular hexagon have the sane perimeter.
The perimeter of the hexagon is 6(x-1) cm
The perimeter of the square is 4x cm.
Find the perimeter of each figure by writing and solving an equation for the variable, x
What is the value of x?
What is the perimeter of each figure?
Answer: (6 cm) or 36 cm.
Step-by-step explanation:The perimeter of a regular hexagon is just the sum of all 6 sides. Because it's a regular hexagon, the perimemter is just six times one side (6 cm) or 36 cm.
The value of x from the given situation is 3 units.
Given that, the perimeter of the hexagon is 6(x-1) cm.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
Here, the regular hexagon has 6 equal sides
The perimeter of regular hexagon = The perimeter of the square
So, 6(x-1)=4x
⇒ 6x-6=4x
⇒ 6x-2x=6
⇒ 2x=6
⇒ x=3 units
Therefore, the value of x from the given situation is 3 units.
