195=67+(200-67)e^(-10k)
195=67+133e^(-10k)
128=133e^(-10k)
128/133=e^(-10k)
ln(128/133)=-10k
k=-ln(128/133)/10
T(t)=67+133e^(tln(128/133)/10), if T(t)=180
180=67+133e^(tln(128/133)/10)
113=133e^(tln(128/133)/10)
113/133=e^(tln(128/133)/10)
ln(113/133)=tln(128/133)/10
10ln(113/133)=tln(128/133)
t=10ln(113/133)/ln(128/133)
t≈42.5 minutes...
t≈40 minutes (to nearest 5 minutes? :P)
Because you can’t simplify anymore within the parentheses you add the like terms a, b, and c
Answer:

Step-by-step explanation:
We know that 1π rad=180°
Hence we can use a proper relation

Solving for x results

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.
Answer:
Scatter plots resembles line graphs in that they are plotted on the x and y axis. The are used because they show how much one variable is affected by another.
Scatter diagrams are important since in statistics they can show the extent of correlation, if any, between the values of observed quantities or a behavior.
