Im sorry free answer haha...thx!
Answer:
Step-by-step explanation:
multiply first equation by 4 and second by 3 respectively:
combine the equations:
divide both sides by -48:
substitute the value of y to the second equation
simplify multiplication:
cancel 12 from both sides:
divide both sides by 4
therefore our solution is
Answer:
≈13degrees
Step-by-step explanation:
It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,
Using the formula, where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get
⇒
Therefore,
⇒
⇒
Thus, the latitude of B is=12.53 degrees≈13degrees
Answer:

Step-by-step explanation:
Answer:
The hypothesis should be retained
Step-by-step explanation:
We are given:
N= 16
n = 4
Level of significance, a = 0.05
From the given data, our ANOVA table will be:
Note: proper ANOVA table is attached
The statistic will be written as:
T = 8/4 = 2
Therefore
The hypothesis should be retained, because we no know that the statistic is in the acceptance area.
