Answer:
24
Step-by-step explanation:
if A is a point between B and C, then'
BA + AC = BC
GIven
AB = 26 and BC = 50
BA = 26
Substitute
26 + AC = 50
AC = 50 - 26
AC = 24
Hence thelength of AC is 24
x + 10 < 50
x < 50 - 10
x < 40
*x<40 or (-∞, 40)
-- B.16 and D.39
24 3/4 divided by 1 3/8 equals 18
Answer:
(a) and
(b) The sample variance is and the sample standard deviation is
Step-by-step explanation:
(a)
The sum of these 17 sample observations is
and the sum of their squares is
(b)
The sample variance, denoted by , is given by
where
Applying the above formula we get that
The sample standard deviation, denoted by <em>s</em>, is the (positive) square root of the variance:
Applying the above formula we get that
