If the scale is
R.F.= 1/2000000
=1/2x 10000x100
1cm=20000m
The scale of a map is given as= 1/2000000
Two town are 4 cm apart on the map.
the actual distance between two towns
=4x 20000
=80000 m
=80000/1000 Km
=80Km
I hope this help you
The area of the circle is 18
It’s the third answer
(2x + 5) x ( 3x -4)
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.
