Step-by-step explanation:
Answer:2.5 kg per meter
Step-by-step explanation:since the rod is uniform i simply divided the weight of the rod(20kg), by the length of the rod(8m). 20kg/8m = 2.5kg/m
Answer:
College students' annual earnings is betweeen $2,514.33 and $3,907.67
Step-by-step explanation:
Hi, first, let´s introduce the formula that we need to use in order to find out the lower and higher limit of the interval.
Now, the only problem here is to find Z(alpha/2), so, let´s define that. Alpha is the remeining area of the normal distribution curve that is out of the limit, in other words, in this case, we need the 98% confidence interval, that means that 2% of the probs are going to be out of the range, therefore, this 2% is alpha. Since we need that the same area is removed from the left and right side of the uniform distribution curve, we need to find the value of Z in the uniform curve distribution table for 1% (that is 2%/2) and due to symmetry, we can now find the values of the interval (this means that we need the value of Z for 0.99, that is 2.33). Now, let´s find out the lower and higher limit of this interval.
So, the college students´annual earnings are between $2,514.33 and $3,907.67 with 98% of confidence.
As it is an equilateral traingle,
Each interior angle will be 180/3 = 60 degree
angle X, Y and Z are 60 degree
Angle W = 180 - 60 = 120 degree ( Linear Pair )
Now, the answers are :
A. w > y
B.w> x
C. y + z = w
E .x+ y = w
The rest Option D and F are incorrect because:
Option D
x + y =z
60 + 60 = 60
but 60 + 60 = 120
Option F
z> x
60>60
But 60 can not be greater than 60
The sign must be of equal ( = )
Answer:
Step-by-step explanation:
1035-15% of 1035= cost price
=1035-15/100x1035
=1035-155.25
=879.75
