Answer:
5 N.
Step-by-step explanation:
Given that,
A force vector M points 3 N in the x-direction and 4 N in the y-direction.
We need to find the magnitude of vector M. The magnitude of the vector when they are perpendicular to each other is given by :
So, the required magnitude of M is 5 N.
Answer:
one solution
Step-by-step explanation:
1. 1=4x-2-3x
2. 1=x-2
3. 1+2=x
4. 3=x
First we need to write the null and alternate hypothesis for this case.
Let x be the average number of text message sent. Then
Null hypothesis: x = 100
Alternate hypothesis: x > 100
The p value is 0.0853
If p value > significance level, then the null hypothesis is not rejected. If p value < significance level, then the null hypothesis is rejected.
If significance level is 10%(0.10), the p value will be less than 0.10 and we reject the null hypothesis and CAN conclude that:
The mean number of text messages sent yesterday was greater than 100.
If significance level is 5%(0.05), the p value will be greater than 0.05 and we cannot reject the null hypothesis and CANNOT conclude that:
The mean number of text messages sent yesterday was greater than 100.
