A new centrifugal pump is being considered for an application involving the pumping of ammonia. The specification is that the flow rate be more than 5 gallons per minute (gpm). In an initial study, eight runs were made. The average flow rate was 6.5 gpm and the standard deviation was 1.9 gpm. If the mean flow rate is found to meet the specification, the pump will be put into service. What is the P-value
Answer:
from the t-distribution table, at df = 7 and t = 2.23
Lies p-values [ 0.05 and 0.025 ]
Hence;
0.025 < p-value < 0.05
Step-by-step explanation:
Given that;
[tex]x^{bar}[/tex] = 6.5 gpm
μ = 5 gpm
n = eight runs = 8
standard deviation σ = 1.9 gpm
Test statistics;
t = ([tex]x^{bar}[/tex] - μ) / [tex]\frac{s}{\sqrt{n} }[/tex]
we substitute
t = (6.5 - 5) / [tex]\frac{1.9}{\sqrt{8} }[/tex]
t = 1.5 / 0.67175
t = 2.23
the degree of freedom df = n-1 = 8 - 1
df = 7
Now, from the t-distribution table, at df = 7 and t = 2.23
Lies p-values [ 0.05 and 0.025 ]
Hence;
0.025 < p-value < 0.05

what is m CDJ?
please help me I'm super confused.
Answer:
34 degrees.
Step-by-step explanation:
Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.
Drop the parentheses and get 7x - 8 = 90.
Add 8 to both sides 7x = 98.
Divide both sides by 7, x = 14.
Plug that x value into (3x-8), [3(14)-8] = 34 degrees.
Answer:
34 degrees
Step-by-step explanation:
So, because mJDK and mJDA lie on a line, they must be supplementary, and since mJDK is 90 degrees, mJDA must be too. So, you know that the combination of mADC and mCDJ must be 90 degrees. 4x+3x-8=90 simplified is 7x=98, which says that x is equal to 14. So you plug in the values for 3x-8, and voila! mCDJ is 34!

Answer: 22% *nevermind :(*
Step-by-step explanation:
Answer:
78% decrease
Step-by-step explanation:
Calculate percentage change
from V1 = 50 to V2 = 11
(V2−V1)|V1|×100
=(11−50)|50|×100
=−3950×100
=−0.78×100
=−78%change
=78%decrease

What is the equation of the line containing the points (5,2), (10,4), and
(15, 6)?
O A. y= x
O B. y = -x+1
C. y = x-3
Answer:
y=2/5x
Step-by-step explanation:
The equation of the line containing the points (5,2), (10,4), and
(15, 6) are,
⇒ y = 2/5x
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (5, 2) and (10, 4).
Now,
Since, The equation of line passes through the points (5, 2) and (10, 4).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (4 - 2) / (10 - 5)
m = 2 / 5
Thus, The equation of line with slope 2/5 is,
⇒ y - 2 = 2/5 (x - 5)
⇒ y - 2 = 2/5x - 2
⇒ y = 2/5x
Therefore, the equation of the line containing the points (5,2), (10,4), and
(15, 6) are,
⇒ y = 2/5x
