Answer:
Option D is correct
Step-by-step explanation:
According to Geometry, A circle is a round plane figure whose boundary (that is the circumference) consists of points equidistant from a fixed point (that is the centre).
Thus, according to the definition of circle in geometry, option D is correct because it gives the correct description about circle while all other options are not correct because they are giving the incorrect description of circle.
Answer:
Step-by-step explanation:
By geometric mean theorem:
By Pythagoras Theorem:
Again by Pythagoras Theorem:
Answer:
$12.89
Step-by-step explanation:
value of tax:
6 : 100 = x : 10.40
x = (10.40 * 6)/100 = $0.624
new amount
10.40 + 0.624 = $11.02
value of tip
17 : 100 = x : 11.02
x = (11.02 * 17)/100 = $1.8734
Final amount
11.02 + 1.8734 = $12.89
Answer:
Slope- m=-3/2
Step-by-step explanation:
Answer:
153.586 close to 154 students
Step-by-step explanation:
mean=61
standard deviation =10
sample 450 students , x between 61 and 71
(x-mean)/deviation for score 61 and 71
61-61/10=0
71-61/10=1
the z-scores is between 0 and 1 ( use calculator)
the percentage is 0.3413 close to 34%
number of students that score between 61 and 71=
450*0.3413= 153.586 close to 154 students
