Answer:
The probability that he teleports at least once a day =
Step-by-step explanation:
Given -
Evan lives in Stormwind City and works as an engineer in the city of ironforge in the morning he has three Transportation options teleport ride a dragon or walk to work and in the evening he has the same three choices for his trip home.
Total no of outcomes = 3
P( He not choose teleport in the morning ) =
P( He not choose teleport in the evening ) =
P ( he choose teleports at least once a day ) = 1 - P ( he not choose teleports in a day )
= 1 - P( He not choose teleport in the morning ) P( He not choose teleport in the evening )
=
=
Answer:
3
Step-by-step explanation:
the initial statement is
y
∝
1
/x
to convert to an equation multiply by k the constant
of variation
y
=
k
×
1
/x
=
k
/x
to find k use the given condition
y
=
5 when x
=
6
y
=
k/
x
⇒
k
=
y
x
=

when
x
=
10
then
y
=

Answer:
296 and 22
Step-by-step explanation:
111/6 = 18.5 according to the chart given, so
x/16 = 18.5.
Multiply both sides by 16 to isolate x.
x = 296
check work:
296/16 = 18.5
do the same to 407:
407/x = 18.5
Mulitply both sides by x.
407 = 18.5x
divide both sides by 18.5 to isolate x.
22 = x
check work:
407/22 = 18.5
distribute
-3y -9 = 2y+3
add 3y to each side
-9 = 5y +3
subtract 3 from each side
-12 = 5y
divide by 5
-12/5 = y
y = -2 2/5
