Answer:
see below
Step-by-step explanation:
The y-coordinates of the points are the same, so the distance between those points will be the difference of the x-coordinates. The first number line shows those x-coordinates plotted properly. It can be used to find the difference between them.
3 because 21/3 is 7. 24/3 is 8. And 27/3 is 9.
70 is a composite number because it can be divided by numbers other than one and itself.
Answer:
a) The expected number of goals team A will score is 5.1
b) The probability that team A will score a total of 5 goals is 0.1147
Step-by-step explanation:
Let X be the amount of goals scored by team A in both matches. Let X1 and X2 be the total amount of goals team A scores in match 1 and 2 respectively, then X = X1+X2, and also
a)
E(X) = E(X1+X2) = E(X1)+E(X2) = 0.6*2+0.4*3 + 0.3*2+0.7*3 = 5.1
b) In order for X to be equal to 5 we have 5 possibilities
- X1 is 0 and X2 is 5
- X1 is 1 and X2 is 4
- X1 is 2 and X2 is 3
- X1 is 3 and X2 is 2
- X1 is 4 and X2 is 1
- X1 is 5 and X2 is 0
Let T1 be a poisson distribution with mean λ = 2, then






Lets do the same with a Poisson distribution T2 with mean λ = 3


Now, we are ready to compute the probability that X is equal to 5.


We can conclude that
P(X = 5) = 0.00823+0.03214+0.05317+0.0471+0.0225+0.0047 = 0.1147
The probability that team A will score a total of 5 goals is 0.1147
Answer:
$48
Step-by-step explanation:
Ashton is saving money for a new bike. He needs 120$ But only has saved 60% so far. How much more money does he need to buy the scooter
Ashton needs money for new bike=120$
savings of ashton is 60 % of his bike cost
hence 60% of 120 dollar will be
His saving=(60/100)*120=7200/100=72$
remaining cost will be obtained by subtracting saved money from total cost
total cost=120 dollar
saved money=72dollar
hence
Remaining more money he needed is =120-72=48$
