Answer: hello your question was poorly written but i was able to the get missing parts online which enabled me resolve your question
answer:
a) a = 0.1096
b) 1.89 watts
Step-by-step explanation:
Std of output voltage = 0.25 volt
H0 : μ = 5 volts
Ha : μ ≠ 5 volts
n = 16
a) Acceptance region = 4.9 ≤ X ≤ 5.1
Determine the value of a
value of a = 0.0548 + 0.0548
= 0.1096
<em>attached below is the reaming solution</em>
note : a is a type 1 error
b) power of test
True mean output voltage = 5.1 volts
P = - 1.89 watts
power cant be negative hence the power of the test = 1.89 watts
Answer:
See attachment
Step-by-step explanation:
The table that represent a direct variation is shown in the attachment.
To determine a direct variation from tables, you need to inspect the y-intercept of each table.
If there is a table with y-intercept of 0, then it represents a direct variation.
Or you could check the table with equation of the form: 
if you cannot see zero in the y-intercepts directly
In the data set below, what is the mode?<br>
15, 21, 26, 25, 21, 23, 28, 21, 25, 23
Brums [2.3K]
Answer:
21
Step-by-step explanation:
mode is the value that occurs frequently
data
15, 21, 26, 25, 21, 23, 28, 21, 25, 23
sort from the smallest
15, 21, 21, 21, 23, 23, 25, 25, 26, 28
15 = 1
21 = 3
26 = 1
25 = 2
23 = 2
28 = 1
the mode is 21 (appear 3 times)
Answer:
Step-by-step explanation :The input-output table is able to “depict the relationship between different sectors of the national economy, and the structural connection of production and final demand in a consistent manner” (KSH, 2005, p. 5). A basic requirement of the table is symmetry, which means that sectoral output and use have to be equal.
im not sure though hope this kinda helps
If P(x) = ax^4 + bx^3 + cx^2 + dx + e has roots at x = 1, 2, 3, 4, then
0 = a + b + c + d + e0 = 16 a + 8b + 4c + 2d + e0 = 81 a + 27b + 9c + 3d + e0 = 256 a + 64 b + 16c + 4d + e
P(0) = 48 e = 48
There are five equations, five unknowns, hence the linear equations can be solved. a is equal to 2, b is equal to -20, c is equal to 70, d is equal to -100 and e is equal to 48
