Answer:
0.484
Step-by-step explanation:
Given that:
Alice defeats Carol 50% of the time.
This implies that, the probability of defeating Carol = 0.5
Also the probability of losing to Carol = 1 - 0.5 = 0.5
Similarly, Alice defeats Betty 40% of the time.
The probability of Alice defeating Betty = 0.4 and the probability of losing to Betty = 1 - 0.4 = 0.6
However, in as much as Alice needs to win two consecutive games, the sequence which satisfies this condition are as follows:
Let W represent Win and L represent L.
Then the conditions are WWW, WWL and LWW
Since the outcome of each game is independent of the other games.
Then, the probability that Alice wins two games against Carol CBC is:
Pr(2W - CBC) = (0.5 × 0.4 × 0.5) + ( 0.5 × 0.4 × 0.5) + ( 0.5 × 0.4 × 0.5)
Pr(2W - CBC) = 0.1 + 0.1 + 0.1
Pr(2W - CBC) = 0.3
The probability that Alice wins two games against Betty (BCB) is:
Pr(2W - BCB) = (0.4 × 0.5 × 0.4) + (0.6 × 0.5 × 0.4) + ( 0.4 × 0.5 × 0.6)
Pr(2W - BCB) = 0.08 + 0.12 + 0.12
Pr(2W - BCB) = 0.32
However, the Probability of winning two consecutive games is the result of the addition of the probability of winning two consecutive games in the sequence CBC together with the probability of winning two consecutive games in the sequence of BCB.
i.e.
Pr(2W) = Pr(2W- CBC) + Pr(2W - BCB)
Pr(2W) = 0.3+0.32
Pr(2W) = 0.62
Finally, to calculate the probability that Alice will get $100 if she chooses the sequence CBC is:
[tex]\dfrac{Pr(2W -CBC)}{Pr(2W)}= \dfrac{0.3}{0.62}[/tex]
[tex]\mathbf{\dfrac{Pr(2W -CBC)}{Pr(2W)}= 0.484}[/tex]
If m∠1 equals (4x + 2) and m∠3 equals (5x − 25), what is the value of x?
Step-by-step explanation: the answer is x = 1/2
The value of x is 27 units.
It is required to find the value of x.
What is angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.
Given:
If m∠1 equals (4x + 2) and m∠3 equals (5x − 25),
According to given question we have,
m∠1 =m∠3
(4x + 2)=(5x − 25)
compare the like terms and simplify we get,
2+25=5x-4x
27=x
Therefore, the value of x is 27 units.

The stem-and-leaf plot shows the test scores of a science class. Use the plot to answer the question.
How many students scored 78?
Answer:
4 students
Step-by-step explanation:
Understanding stem-and-leaf plots
A stem and leaf plot is designed in a way to group the numbers by their values before the ones place;
i.e. 92, 100, 101, 103, 113
Charted as
9 | 2
10 | 0 1 3
11 | 3
So, with that in mind we know 78 is grouped under the 7 | # # #
stem and has the leaf of 8 which is displayed by # | # # # 8
SO,
TO SOLVE:
Count the 8's under the 7 | # # # # group
We can see that there are 4 8's under that section, and assuming that each number is representative of one students score, we can conclude that 4 students scored 78

Titus took 30 minutes to walk 2 miles at a constant rate. Let d represent the distance Titus walks in miles after t minutes. What are two different constants of proportionality for the relationship between distance, in miles, and time, in minutes?
Answer:
15 and 1/15
Step-by-step explanation:
Given
Time (t) = 30 minutes
distance (d) = 2 miles
To determine the first constant of proportionality
Let time be directly proportional to distance.
t = kd
Where k is the constant of proportionality
Make k the subject
k = t/d
Substitute values for t and d
k = 30/2
k = 15
To determine the second,
Let distance be directly proportional to time.
d = kt
Make k the subject
k = d/t
Substitute values for d and t
k = 2/30
k = 1/15
Hence, the constant of proportionality are
15 and 1/15

A backpack will hold 2,808 grams. If a T-shirt weighs 156,000 milligrams, how many T-shirts will the backpack hold?
Answer:
18 T-shirts
Step-by-step explanation:
1gram = 1000milligrams
1gram × 156000milligrams ÷ 1000milligrams
The milligrams unit cancel out each other thus grams remains as the main unit.
=156grams
1 T-shirt = 156grams
1 T-shirt × 2808grams ÷156grams
The grams unit cancel out each other thus T-shirt remains as the main unit.
=18 T-shirts

19. The velocity of an object fired directly upward is given by V = 35 – 9.8t, where t is time in seconds. Which inequality describes the velocity when t is between 0.5 and 1.5 seconds? (HINT: Remember that when you multiply an inequality by a negative number, you must switch the direction of the inequality.)
A. 20.3 > 35 - 9.8t > 30.1
B. 4.9 > t > 14.7
C. 0.5 35 - 9.8t > 4.9
D. V < 30.1
E. 20.3 < 35 - 9.8t < 30.1
F. 14.7 > 35 - 9.8t > 4.9
Answer:
20.3 < 35 - 9.8t < 30.1
Step-by-step explanation:
Given the Velocity model:
V = 35 – 9.8t ; t = time in seconds
V when t is between 0.5 and 1.5
V when t = 0.5
V = 35 - 9.8(0.5)
V = 35 - 4.9 = 30.1
Vt=0.5 = 30.1
V when t = 1.5 ;
V = 35 - 9.8(1.5)
V = 35 - 14.7 = 20.3
Vt= 1.5 = 20.3
Hence V, between, t = 0.5 and t = 1.5
Vt=1.5 < V < Vt=1.5
20.3 < V < 30.1
V = 35 - 9.8t
20.3 < 35 - 9.8t < 30.1

An 80 metre long train crosses a 120 metre long platform in 20 seconds, what is the speed of the train per hour?
ans:
Total distance= length of train + length of platform
I.e 80+120= 200 m but need in kmph so 0.2 km
Time = 20 second but need in hours so 20/(3600)= 1/(180)
Speed = distance / time = 0.2*180= 36 kmph

(285+15y≥510)-285

y≥15
9514 1404 393
Answer:
4. 2.5x +15y > 510
5. y > 10
Step-by-step explanation:
4. The revenue from each of x cupcakes is 2.50, so the total revenue from cupcake sales is 2.50x.
The revenue from each of y cakes is 15.00, so the total revenue from cake sales is 15.00y.
The total revenue from sales of cupcakes and cakes is more than 510, so we can write the inequality ...
2.5x +15y > 510 . . . . possible combinations of cakes and cupcakes
__
5. For x=144 the constraint on y is ...
2.5(144) +15y > 510
360 +15y > 510
15y > 150
y > 10 . . . . possible number of cakes sold
If f(x) = -x + 4 and g(x) = x^2 - 5, then g(f(-1)) = ?
Answer:
g(f(-1)) = 20
Step-by-step explanation:
first we need to compute f(-1)
f(-1) = -( -1 ) + 4 = 1 + 4 = 5
then we take g(5):
g(5) = ( 5 )^2 - 5 = 25 - 5 = 20
