Answer:
x = 38 degrees.
The angle marked 2x-1 =75 degrees
Step-by-step explanation:
the opposite angles of a parallelogram are equal.
so:
2x -1 = 75
2x = 76
x = 38
Hope this helps
Answer:
X = 12/60%
60% = 0.6
X = 12/0.6
X = 20.
For the second one, multiply 350 by 0.02, which is just 2% in decimal form.
350*0.02 =7
That's 7 eggs.
Hope this helps!
Answer:
x=70
Step-by-step explanation:
angle FED and GEC are vertical angles so they both equal 50
angle DEB and CEA are also vertical angles so they both equal 20
50+20=70
Answer:
(a) Mean = 36.05; (b) median = 37; (c) mode = 37
Step-by-step explanation:
I am assuming your DFT is like this:
(a) Mean
The mean is the sum of all the data points divided by the number of points. I have done some of the calculations for you in the table below
(b) Median
The median is the middle value in your list of observations.
Your data set contains 19 terms, so the middle is (19/2)th term.
Count down the column of cumulative frequency (cf) until cf = 9½.
The 9½th term is 37.
Median = 37
(c) Mode
The mode is the value that appears most often in your list of observations.
It is obvious from your table that the number that occurs most frequently is 37.
Mode = 37
The diagram below shows that the score of 37 is predominant.
