Two baseball teams meet in a playoff series at the end of the regular season. Team A won 55 of 81 games played in its home stadium during the regular season, while Team B won 48 of 81 games played in its home stadium. The first two games of the series will be played in Team A's home stadium, the next two games in Team B's home stadium. In the absence of any other information, which expression is equal to the probability that Team A will win the first four games in a row?
Answers
Answer:
Assuming the statistics are independent of the visiting team, then probability of team A winning in home turf is P(A)=55/81, and winning as a visitor of team B is P(B)=(81-48)/81=33/81.
So winning all four games,
P = P(A)*P(A)*P(B)*P(B)

Matteo is working two jobs, making $15 per hour at the movie theater and $18 per hour washing cars. Last week Matteo worked a total of 30 hours and earned a total of $480. Determine the amount of hours Matteo worked at the movie theater and the cash wash.
Answers
Answer:
movie theatre = 20 hours
car wash = 10 hours
Step-by-step explanation:
this would be solved using simultaneous equation
let a = hours worked in theatre
b = hours spent wash cars
15a + 18b = 480 eqn 1
a + b = 30 eqn 2
multiply eqn 2 by 15
15a + 15b = 450 eqn 3
subtract 1 from 3
3b = 30
b = 10 hours
substitute for b in eqn 2
a + 10 = 30
a = 20 hours
Harvey has $390 in a savings account that earns 6% simple interest each year. How much interest will Harvey earn in 2 years, assuming she does not add or take out any money? How much total money is in the account at the end of two years?
Answers
Answer:
She will earn $46.8 of interest. $436.8 is in her account total after the two years
Step-by-step explanation:
You would find out how much 6% of $390 is which would be $23.4 and then you would find out how much it would be after two years so you would $23.4 times two which is $46.8 so the interest would be $46.8. Then you would add the interest to the $390 that was put into the savings so you would do $390 + $46.8 = $436.8

Answer:
92 is your answer
Step-by-step explanation:
we have
3x/4-1=x/2+7 side of square are equal
3x/4-x/2=7+1
(3x-2x)/4=8
x=8×4=32
length =3×32/4 -1=24-1=23
now
perimeter=4×length=4×23=92 units
Answer: The perimeter of the square is 92 units.
Step-by-step explanation:
All four sides of a square are equal. Set the given values 3/4x - 1 and 1/2x + 7 equal to one another. It should like this: 3/4x - 1 = 1/2x+7. The next step is solving for x. We get x = 32 as our answer. See the image of the work below if you are confused. :) Next, plug in this answer to the original equations: 3/4x-1 and 1/2x+7.
3/4(32) - 1 = 23
1/2(32) + 7 = 23
After basic substitution, we will conclude that each side of the square is 23 units long. To find perimeter use the equation 4s (let s represent sides). 4(23) = 92 units. Hope this was helpful!

Mike took an uber from his home to the airport. The driver charges an initial fee of $6 and $3 per mile. The total fare was $24 not including the tip. How many miles did Mike travel by uber on this ride? *
Answers
Answer:
About 5 miles
Step-by-step explanation:
At first, I thought it would be 6 miles because 6x3 is 18 plus the initial 6 dollars which is 24. However, it says that it does not include the tip, which means that Mike DID tip the driver. So there has to be some space for the tip. If it was 6 miles it would be 24 dollars, but there is no more space for the tip. So it has to be 5 miles, because that will be 21 dollars, and assuming the tip could be about 3 dollars, then that would total up to 24 dollars.

Answers
Answer:
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

The factored expression is 2(x² + 5)(x + 3).
Step-by-step explanation:
Hey there!
We can use a factoring technique referred to as "grouping" to solve this problem.
Grouping is used for polynomials with four terms as a quick and easy factoring method to remove the GCF and get down to the initial terms that create the expression/function.
Grouping works in the following matter:
Given equation: ax³ + bx² + cx + dGroup a & b, c & d: (ax³ + bx²) + (cx + d)Pull GCFs and factorsLet's apply these steps to the given equation.
Given equation: 2x³ + 6x² + 10x + 30Group a & b, c & d: (2x³ + 6x²) + (10x + 30)Pull GCFs and factors: 2x²(x + 3) + 10(x + 3)As you'll see, we have a common term with both sides of the expression. This term, (x + 3), is a valuable asset to the factoring process. This is one of the factors for our expression.
Now, we use our GCFs to create another factor.
List GCFs: 2x², 10Create a term: (2x² + 10)Finally, we'll need to simplify this one by taking another GCF, 2.
Pull GCF: 2(x² + 5)Now that we have this term, we need to understand that this could also be factored further using imaginary numbers, but it is also acceptable to leave it in this form.
Therefore, we have our final factors: 2(x² + 5) and (x + 3).
However, when we factor, we place all of our terms together. This leaves us with the final answer: 2(x² + 5)(x + 3).

Answers
Answer: 90km/hour
Step-by-step explanation:
The formula for speed is given as:
= Distance / Time
where,
Distance = 120km
Time = 80 minutes = 80/60 = 1 1/3 hours
Speed = Distance / Time
= 120 / 1 1/3
= 120 / 4/3
= 120 × 3/4
= 90km/hour
The speed is 90km/hour.
