Answer:
AD = 12 units
Step-by-step explanation:
AD = CD
so
4x = 10x-18
subtract 10x from both sides to get:
-6x = -18
divide each side by -6 to get:
x = 3
insert x into your problem and you get 4(3) which equals 12

Answer:
$3103.6
Step-by-step explanation:
Given data
Total sales= $26,480
Returns and Allowances=$1250
Commission = 7%
Let us find the amount in commission earned
=7/100*26,480
=0.07*26480
=$1853.6
Hence the gross earnings
=1853.6+1250
=$3103.6
Answer:6/7
Step-by-step explanation:
so basically given observation is u got a tail from a biased coin.
so our favorable case is getting a tail from biased coin.
we will use the probability for it:
p1= probability of getting choosing biased coin and getting tail =probability of choosing biased coin* probability of tail = 3/4*1
p2= probability of choosing a fair coin and getting tail= probability of choosing fair coin*probability of getting tail on it = 1/4*1/2 = 1/8
so p(E)= p1/(p1+p2)= 3/4/(3/4+1/8)=7/8
