Answer:
a. There are 12 observations from the resulting data set.
b. This is an analytic study. It compares the flow rates through a solenoid valve based on three factors at four different levels.
Step-by-step explanation:
Observations of the dependence of flow rate
Factors Armature Spring Bobbin
Lengths Load Depth
Levels
Low 1 1 1
Moderate 1 1 1
High 1 1 1
Extreme 1 1 1
Total observations 4 4 4
Number of observations = 12
b) Whereas enumerative studies are statistical studies carried out to draw a conclusion on a process or a condition, analytic studies are statistical studies that compare two or more groups or sets of data to improve future performance. The focus of an analytic study is on the process rather than the condition. Enumerative studies tend to explain, evaluate, and describe the condition of the dataset.
Answer:
$23
Step-by-step explanation:
1. 80 divided by 4= 20
2. 20 times 15%
3. 20 times 0.15= 3
4. 20+3=23
5. $23 after the raise
1. The question is incomplete
2. Answer=D
3. Answer=B
LCM of 24 and 60=120
120seconds=2minutes
4. Answer=D
4.5 miles x miles
_________= _________
15 mins 75 minutes
cross multiply
15x=337.5
divide both sides by 15
x=22.5
5. Honestly, the number of weekdays per month varies...
Answer:
20.
m = -52
22.
x=13
24.
a=-90
26.
n=-2
28.
a=9
30.
m=-10
Step-by-step explanation:
20. m/4=-13
m = -13*4 = -52
22. -143=-11x
x=-143/-11 =13
24. -5=a/18
a=-5*18= -90
26. n-8=-10
n=--10+8
n=-2
28. a+11=20
a=20-11
a=9
30. 18+m=8
m=8-18
m=-10
Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
(not my answer btw)
