Answer:
Answer =b. Since the p-value > α, do not reject the null hypothesis.
Step-by-step explanation:
The null hypothesis is to be rejected if the p- value is less than the given significant level. In this case, the p-value is 0.418 and level of significance α=0.05; the p-value is greater than level of significance therefore we do not reject the null hypothesis.
Answer:28.071
Step-by-step explanation:
Given
vector component is (15,8)
i.e. its x component is 15 from origin and y component is 8 m
So angle made by vector with x axis is


Answer:
First Option 
Step-by-step explanation:
To graphically add two vectors a and b using the -tail and tip-method, you must draw the tail of b at the tip of the vector a. Then you must draw a line that goes from the tail of a to the tip of b. This line represents the sum of
.
In this problem, notice that the tail of the vector w is on the tip of the vector v. The line that joins the tail of v with the tip of w is u.
Therefore we can say that
.
The answer is the first option
Answer:
The error interval for x is:
![[15.375,15.384]](https://tex.z-dn.net/?f=%5B15.375%2C15.384%5D)
Step-by-step explanation:
In order to determine the error interval for x, We have to get the all the number which could be rounded off to
.
These number can be listed in order such as:
15.375 15.376 15.377 15.378 15.379 15.380 15.381 15.382 15.383 15.384
Therefore, the error interval for x is:
![[15.375,15.384]](https://tex.z-dn.net/?f=%5B15.375%2C15.384%5D)
Craig has every 13th night and Edie has every 5th night off.
You have to find LCM - the Least Common Multiple that is the smallest ("least") number that both 13 and 5 will divide into.
Since numbers 13 and 5 are both prime, then LCM(13,5)=13·5=65.
This means, they will have the same every 65th night off.
