Step-by-step explanation:
Vlookup is a technique in excel which enables users to search for criterion values. It is vertical lookup function in excel which return a value from a different column. The formula for Vlookup function is:
=Vlookup'select cell you want to look up in' select cell you want to lookup from' select column index number' true/false.
where true is approximate match and false is exact match.

Answer:
(1/10)∛100 ≈ 0.4642
Step-by-step explanation:
For a cube of volume V, the edge length is ...
s = ∛V
and the area is ...
A = 6s² = 6V^(2/3)
Then the ratio of area to volume is ...
r1 = A/V = 6V^(2/3)/V = 6V^(-1/3)
If the value of V is increased by a factor of 10, the ratio of area to volume is now ...
r2 = 6(10V)^(-1/3)
The factor by which the ratio changed is ...
r2/r1 = (6(10V)^(-1/3))/(6V^(-1/3)) = 10^(-1/3) = (1/10)∛100
The surface area per unit volume changes by a factor of (∛100)/10.
___
<em>Example</em>
For a cube of side length 2, the volume is 2³ = 8 and the surface area is 6·2² = 24. The ratio of surface area to volume is 24/8 = 3.
Multiplying the edge length by ∛10, we now have a volume of (2∛10)³ = 80, and a surface area of 6(2∛10)² = 24(10^(2/3)). The ratio of surface area to volume is ... 24(10^(2/3))/80 = 0.3∛100.
The ratio of area to volume changed by a factor of (0.3∛100)/3 = (∛100)/10, as above.
Answer:
Median = 36
Step-by-step explanation:
To calculate the median number of miles Jenna cycled, we must first rearrange the numbers. The rearranged numbers are:
28, 31, 36, 36, 42, 48, 52
The middle number is 36
The median it therefore = 36
Answer:
The Three way mixed ANOVA
Step-by-step explanation:
The Three factor repeated measures ANOVA analysis otherwise referred to as the Three way mixed ANOVA should be used for the analysis.
This is because we are comparing three independent variables in the context.
• People type (statistic lectures and students)
• Imagery type (positive, neutral and negative imagery)
• Repeated measure: Before and After images shown
• Measuring the dependent variable positive arousal as shown in the table attached to the answer.
After going through the table attached you will see that there should be performed a three factor repeated measures ANOVA analysis.
