The fourth one I think hope it helps
Given that an experiment results in one of the sample points E1, E2, E3, E4,
or E5.
Then P(e1) + P(e2) + P(e3) + P(e4) + P(e5) = 1
If P(E1)=0.1, P(E2)=0.1, P(e4)=0.2, and
P(E5)=0.3., then P(E1) = 1 - 0.1 - 0.1 - 0.2 - 0.3 = 0.3
Therefore, P(e3) = 0.3
Answer:
Option 400p/500-p
Step-by-step explanation:
Let the number of newspaper A sold be 'x'
and the number of newspaper A sold be 'y'
Therefore,
Total revenue = $1x + $1.25y
Total newspapers sold = x + y
Therefore,
according to the question
r = 
..........(1)
and,
p = 
or
(x + y)p = 100x
or
y = 
or
y = 
substituting y in 1
r = 
or
r = 
or
r = 
multiply and divide the RHS with 4
we get
r = (400p)÷(500-p)
hence,
Option 400p/500-p
Answer:
<em>The National football league has </em><em>464 more players</em><em> than the Major League baseball.</em>
Step-by-step explanation:
Since there are 30 teams in the Major league baseball and there are 40 players in each team, this means that the total number of players in the Major league baseball is:
30 × 40 = 1200 players
Since there are 32 teams in the National football league and there are 52 players in each team, this means that the total number of players in the National football league is:
32 × 52 = 1664 players
Therefore, the difference in the number of players in both leagues is:
<em>1664 - 1200 = 464 players</em>
<em></em>
Therefore, the National football league has <em>464 more players</em> than the Major League baseball.
Ice cream = 4 1/2 gallons
milk = 6 3/10 gallons
ice cream: 4 1/2 = (4*2 + 1)/2 = 9/2
milk: 6 3/10 = (6*10 +3)/10 = 63/10
milk:ice cream proportion: a:b = c:d where a*d = b*c
a = 63/10 ; b = 9/2 ; c = x ; d = 1
63/10:9/2 = x:1
63/10 * 1 = 9/2 * x
63/10 = 9x/2
63/10 * 2 = 9x/2 * 2
126/10 = 9x
126/10 * 10 = 9x * 10
126 = 90x
126/90 = 90x/90
1 36/90 = x
x = 1 36/90 simplified to 1 13/30
1 13/30 gallons of milk will make 1 gallon of ice cream.
