The CDC is investigating if the average blood pressure of the US population is
different from 123. A hypothesis test is conducted which returns a sample mean of
128 and a p-value of 0.0037. What is the appropriate conclusion at the 5%
significance level?
Option B. The appropriate conclusion at the 5% significance level is to Reject the null hypothesis, the population mean is significantly different from 123
How to test the hypothesisH0: mean = 123
H1 : mean ≠ 123
We have the p value of the statistics stated already in the question as p value = 0.0037.
The level is significance that we have been given in the question is 5% = 0.05
We are to test here if the true mean is different from 123.
Hence we would be testing the p value against the significance level.
We can see that P value is < level of significance.
0.0037 < 0.05
Hence we would reject the null hypothesis.

What is linear equation ?A straight line equation and equations with a maximum order of one are referred to as "linear equations." The formula for the linear equation can be written as Y = mx + b, where m is the slope of the line, b is the y-intercept, and x and y are the variables. Slopes tell us the direction and steepness of a line. The value of y when x is 0 is referred to as the y-intercept because (0,y) is the point where the line crosses the y-axis.
CalculationLet's say the number of calls on the second night was x.
The first evening was then x+7.
The third evening she received 4x calls.
Add them up to make 109 calls....
x + x+7 + 4x = 109
6x + 7 = 109
6x = 102
x = 17 calls
x+7 = 24 calls
4x = 68 calls

What is quotient?A quotient is the number which is generated when we perform division operations on two numbers. Basically, it is the result of the division method. There are four main terminologies used in the arithmetic division such as divisor, dividend, quotient and remainder. For example, 15/3= 5 .The number that is being divided ( 15) is called the dividend, and the number that it is being divided by (3) is called the divisor. The result of the division(5) is the quotient.

AM median CM=5x-2 MB = 3x +12 Find CB
The length of the segment CB in triangle ABC where [tex]\overline{AM}[/tex] is a median line and CM = 5·x - 2, MB = 3·x + 12, CM = MB, is 66 units
What is a median line of a triangle?A median line is a line that is drawn from a vertex of a triangle to the middle of the opposite side such that the it bisects the opposite side.
The parameters are; [tex]\overline{AM}[/tex] = A median line
Length of segment CM = 5·x - 2
Length of segment MB = 3·x + 12
Required; The length of segment CB
The median line [tex]\overline{AM}[/tex] bisects the segment CB
Therefore; CM = MB
CB = CM + MB (Angle addition postulate)
Which gives; 5·x - 2 = 3·x + 12 (substitution property of equality)
5·x - 3·x = 2 + 12 = 142·x = 14
x = 14 ÷ 2 = 7
x = 7CB = CM + MB
CB = (5·x - 2) + (3·x + 12)
Which gives; CB = 8·x + 10
x = 7
CB = 8×7 + 10 = 66
The length of segment CB = 66

Answer:
68°
Step-by-step explanation:
The angles are equal to each other. Set them equal and solve for x
5x + 18 = 8x - 12 Subtract 5x from both sides of the equation
18 = 3x - 12 Add 12 to both sides of the equation
30 = 3x Divide both sides by 3
10 = x
Now that you have found x plug is back into 5x + 18
5(10) + 18
50 + 18 = 68
Answer:
∠ FLJ = 68°
Step-by-step explanation:
∠ EKG and ∠ FLJ are alternate exterior angles and are congruent , then
8x - 12 = 5x + 18 ( subtract 5x from both sides )
3x - 12 = 18 ( add 12 to both sides )
3x = 30 ( divide both sides by 3 )
x = 10
Then
∠ FLJ = 5x + 18 = 5(10) + 18 = 50 + 18 = 68°

What is volume?The amount of space occupied by a three-dimensional object or region of space.
Given that, Anna is going to clean the fish tank, which measures 48 inches long by 11 inches wide by 35 inches high
The fish tank is cuboidal,
Volume of cuboid = length*width*height
Therefore, volume of fish tank = 48*11*35 = 18,480 in³
1 gallon = 231 in³
So, 18,480 in³ = 18,480/231 gallons = 80 gallons

There are multiple ways to solve this system, but here's what I did:
Solve the both equations for s:
s/2 + 5t = 3 + 5t ⇒ s = 6
3t - 6s = 9 + 3t ⇒ s = -3/2

The equivalent rational expression with the same denominator as given will be 8(c - 8)/[(c - 3)(5c - 9)(c - 8)] and 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)].
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
As per the given expression,
8/(5c² - 6c - 27) , 2c/(5c² - 31c - 72)
Now, take the first denominator,
5c² - 6c - 27 = 5c² - 15c + 9c - 27
⇒ 5c(c - 3) - 9(c - 3)
⇒ (c - 3)(5c - 9)
Take the second denominator
5c² - 31c - 72 = 5c² - 40c + 9c - 72
⇒ 5c(c - 8) + 9(c - 8)
⇒ (c - 8)(5c + 9)
Therefore, the expression converts as,
8/[(c - 3)(5c - 9)] , 2c/[(c - 8)(5c + 9)]
8/[(c - 3)(5c - 9)] = 8(c - 8)/[(c - 3)(5c - 9)(c - 8)]
2c/[(c - 8)(5c + 9)] = 2c(c - 3)/[(c - 3)(5c - 9)(c - 8)]

We know that the sum of all angles of triangle is 180°
∠R + ∠S + ∠T = 180°
9x + 4 + 3x - 2 + 3x - 2 = 180°
15x + 4 - 4 = 180°
