Answer:
65 = 6x + 7
6x = 58
x = 9.6666666...
65 + y + 9 = 180
y = 106
Step-by-step explanation:
Local Calls = 36
Distance calls = 20
Ratio would be: = 36/20 = 18/10 = 9/5
In short, Your Answer would be Option A
Hope this helps!
Answer:
Step-by-step explanation:
Hello!
What you want to test is if there is a difference between the number of courses taken by students of different years, you can determine 4 populations of students:
Population 1: Freshmen
Population 2: Sophomores
Population 3: Juniors
Population 4: Seniors
To each population you measured the study variable, setting 4 different variables. To compare these variables the best way is to make one test where you compare the four populations at the same time, so the hypothesis is:
H₀: μ₁ = μ₂ = μ₃ = μ₄
H₁: At least one of the population means is different from the others.
The most appropriate test to use to compare the population mean of the 4 groups is an ANOVA.
I hope you have a SUPER day!
Answer:
Step-by-step explanation:
Acceleration is second derivative of distance and are related as:
Integrating both sides w.r.to t
Using initial value
We have to calculate the distance covered in time interval [0,5], so:
![\int\limits^5_0 \frac{ds}{dt}=\int\limits^5_0 {\frac{1}{t+2}} \, dt\\\\s(t)=[ln|t+2|]^5_0\\\\s(t)=ln|5+2|+ln|0+2|\\\\s(t)=(ln|7|+ln|2|)\,ft](https://tex.z-dn.net/?f=%5Cint%5Climits%5E5_0%20%5Cfrac%7Bds%7D%7Bdt%7D%3D%5Cint%5Climits%5E5_0%20%7B%5Cfrac%7B1%7D%7Bt%2B2%7D%7D%20%5C%2C%20dt%5C%5C%5C%5Cs%28t%29%3D%5Bln%7Ct%2B2%7C%5D%5E5_0%5C%5C%5C%5Cs%28t%29%3Dln%7C5%2B2%7C%2Bln%7C0%2B2%7C%5C%5C%5C%5Cs%28t%29%3D%28ln%7C7%7C%2Bln%7C2%7C%29%5C%2Cft)
