To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)

Answer:
Step-by-step explanation:
line perpendicular to ax+by=c is
bx-ay=k, where k is a constant.
if it passes through (-1,2) then
b(-1)-a(2)=k
or k=b-2a
so reqd. eq . is bx-ay=b-2a
Answer:
27 minutes to complete the painting of 4 walls
Step-by-step explanation:
since 16m with 9p --> 8 walls
x minutes with 4p --> 6 walls?
let x= minutes
6 walls painted=(8/144 walls painted per minute)x
simplify
x= 6 divided by (8/144)
x=108 minutes (to complete 6 walls)
108/4=
27 minutes to complete the painting of 4 walls
Answer:
3
Step-by-step explanation:
(2 x 0.38) + (5 x 0.24) + (2 x 0.83) = £3.62
£9.00 - £3.62 = £5.38
£5.38 - (2 x 1.50) = £2.38
£5.38 - (3 x 1.50) = 88p!
