If you're just trying to find 85% of 17, you would do 17 * .85 which gives us 14.45
Step-by-step explanation:
a) X is a discrete uniform distribution. As the number of outcomes is only 3.
b) sum is at least 4
X ≥ 4
i.e (1,3) or (2,3)
probability of X ≥ 4 is 2/3
2/3= 0.667
66.7 % is the probability of the outcome to have a sum at least 4.
c) The 3 likely outcome of X
<em>(1,2) where X ; </em> 1+2=3
<em>(1,3) where X ;</em> 1+3=4
<em>(2,3) where X ;</em> 2+3=5
Mean = 3+4+5/ 3
Mean = 4

P=x+38
add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10
set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x
then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46
sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11
Answer:
$18.15
Step-by-step explanation:
Given that price before tax = $220
State sales tax rate = 4.6%
Dollar amount of state sales tax,
= 4.6% x $220
= 0.046 x 220
= $10.12
County sales tax rate = 3.65%
Dollar amount of state sales tax,
= 3.65% x $220
= 0.0365 x 220
= $8.03
Total amount of sales tax = $10.12 + $8.03 = $18.15
