Answer:
[tex]P=4.41205084*10^2^1[/tex]
Step-by-step explanation:
From the ques ton we are told that
Total amount N=15
Choices within 10 pop, 25 reggae, 10 blues
Generally for equal amount in her play list she's mathematically Going to have 5 of each kind Pop,Reggae,Blues
Therefore
Let the amount of differnt playlist be given as P
[tex]P=^1^0C_5*^2^5C_5*^1^0C_5*15![/tex]
[tex]P=252*53130*252*1307674368000[/tex]
[tex]P=4.41205084*10^2^1[/tex]
Therefore [tex]P=4.41205084*10^2^1[/tex] different playlists are possible
Consider the following work breakdown structure: Time Estimates (days) Activity Precedes Optimistic Most Likely Pessimistic Start A,B - - - A C,D 44 50 56 B D 45 60 75 C E 42 45 48 D F 31 40 49 E F 27 36 39 F End 58 70 82 What is the probability that the critical path for this project will be completed within 210 days
Answer: the probability that the critical path for this project will be completed within 210 days is 0.99725
Step-by-step explanation:
Given that;
Work break down is;
Time Estimates (days)
Activity Precedes Optimistic Most Likely Pessimistic
Start A,B - - -
A C,D 44 50 56
B D 45 60 75
C E 42 45 48
D F 31 40 49
E F 27 36 39
F End 58 70 82
we know that;
Expected Time = ( Optimistic Time + ( 4 × most likely time) + pessimistic time) / 6
and
Variance = [( pessimistic time - Optimistic time) / 6 ]²
so
ACTIVITY EXPECTED TIME VARIANCE
A (44 + (4 × 50) + 56) / 6 = 50 ((56 - 44) / 6)² = 4
B (45 + (4 × 60) + 75) / 6 = 60 ((75 - 45) / 6)² = 25
C (42 + (4 × 45) + 48) / 6 = 45 ((48 - 42) / 6)² = 1
D (31 + (4 * 40) + 49) / 6 = 40 ((49 - 31) / 6)² = 9
E (27 + (4 * 36) + 39) / 6 = 35 ((39 - 27) / 6)² = 4
F (58 + (4 * 70) + 82) / 6 = 70 ((82 - 58) / 6)² = 16
ACTIVITY DURATION ES EF LS LF SLACK
A 50 0 50 0 50 0
B 60 0 60 30 90 30
C 45 50 95 50 95 0
D 40 60 100 90 130 30
E 35 95 130 95 130 0
F 70 130 200 130 200 0
FORWARD PASS:
ES = MAXIMUM EF OF ALL PREDECESSOR ACTIVITIES; 0 IF NO PREDECESSORS ARE PRESENT.
EF = ES + DURATION OF THE ACTIVITY.
CRITICAL PATH = PATH WITH THE LONGEST COMBINED DURATION VALUE AND 0 SLACK.
CRITICAL PATH = ACEF
DURATION OF PROJECT = 200
Now the probability
VARIANCE OF CRITICAL PATH = SIGMA(VARIANCE OF THE CRITICAL PATH) = 25
STANDARD DEVIATION OF CRITICAL PATH = SQRT(VARIANCE OF CRITICAL PATH) = 5
EXPECTED TIME = DURATION OF THE PROJECT = CRITICAL PATH = 200
DUE TIME = 210
Z = (DUE TIME - EXPECTED TIME) / STANDARD DEVIATION OF CRITICAL PATH)
Z = (210 - 200) / 5 = 2
Now form the Normal Distribution Table;
Z = 0.99725
Therefore, the probability that the critical path for this project will be completed within 210 days is 0.99725

Answer:
1. -39
2. 49
3. 32
Step-by-step explanation:
absolute values are always positive!!!
|-39| = 39 but since there is a minus sign outside the lines it is -39
|-44| = 44+5= 49
And 50 - 18 = 32 (|-18| = 18)
Solve:
6 divided by 1/5
Answer:
30
Step-by-step explanation:
6/1 divided by 1/5...(turn the second fraction into 5/1)
therefore...6/1 multiplied by 5/1
=6 multiplied by 5= 30
6 divided by 1/5 is equal to 30.
To solve 6 divided by 1/5, we can multiply the dividend (6) by the reciprocal of the divisor (1/5). The reciprocal of a fraction is obtained by flipping it, so the reciprocal of 1/5 is 5/1.
6 ÷ 1/5 = 6 × 5/1
Multiplying:
6 × 5 = 30
Therefore, 6 divided by 1/5 is equal to 30.

What is the constant of proportionality for the relationship shown in the table? x 2 4 6 8 y 1 2 3 4
1/2
2
or not proportional
Answer:
1/2
Step-by-step explanation:
Given
x 2 4 6 8
y 1 2 3 4
Required
Determine the constant of proportionality (k)
The relationship between x and y is:
[tex]y = kx[/tex]
When y = 2, x = 4;
So, we have:
[tex]2 = k * 4[/tex]
[tex]2 = 4k[/tex]
[tex]4k = 2[/tex]
Make k the subject
[tex]k = \frac{2}{4}[/tex]
[tex]k = \frac{1}{2}[/tex]
Hence, the constant of proportionality is 1/2

solve using elimination x+2y=4 -x-y=2
Answer:
x=-8 y=6
Step-by-step explanation:
Add the two equations together. This cancels the x and gets us y=6
Then substitute y in more the first equation which gets us -8
Answer: y = 6 x = -8
Step-by-step explanation:
X+2Y=4
-X-Y=2
(Combine like terms)
Y= 6
(Plug in 6 for y)
X+2(6)=4
X+12=4
X= -8

How can you tell from a graph whether two functions are inverses of each
other?
o the graphs of the functions are reflections across the line y=x.
o the graphs of the functions are reflections across the x-axis.
o the graphs of the functions are reflections across the y-axis.
o it is not possible to tell from a graph if functions are inverses of each other.
Answer:
if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
The pie chart shows information about voters in an election. 3360
more women voted than men. Work out the total number of voters.
Answer:
4838 total number of voters
Step-by-step explanation:
In a whole circle there 360°, in a straight line theres 180°.
180-110=70 first to break it down to find the degrees of women.
180+70=250° for women.
250°=3360
we need to find 110° of men
25°=336
times 4
100°=1344
divide by 10
10°=134.4 round down 134
1344+134=1478
3360+1478=4838
The agriculture club is planting vegetable gardens of land that measures 1 3/4 of an acre. Each garden will measure 1/8 of an acre. What is the greatest number of gardens that can be planted?
Answer: 14 gardens
Explanation:
1. You can either turn the fractions into decimals (1.75 and 0.125) or make the denominators the same (1 6/8 and 1/8)
2. multiplying 3/4 by the 2 to get the least common multiple, which in this case is 8. (3/4x2=6/8)
3. Divide the number of acres available (1 6/8) by the number of acres needed for each garden (1/8) to get the answer. (1 6/8÷1/8=14)
