Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
32.3 , 28.8 , 29.1 , 29.5 , 30.8 , 31.0 , 17.5 , 34.5 , 23.5 , 33.0 , 31.7 , 28.6 , 27.4
Reordered data:
17.5, 23.5, 27.4, 28.6, 28.8, 29.1, 29.5, 30.8, 31.0, 31.7, 32.3, 33.0, 34.5
The mean ; m
Mean, m = Σx /n
Σx = 377.7
n = sample size = 13
m = Σx / n = 377.7 / 13 = 29.05
Median = 1/2(n+1)th term
= 1/2(14) = 7th term = 29.5
Range = maximum - minimum
Range = 34.5 - 17.5 = 17
Lower quartile (Q1) = 1/4(n+1)th term
1/4(14)th term = 3.5th term
(3rd + 4th) / 2
= (27.4 + 28.6) / 2
= 28
Upper quartile (Q3) = 3/4(n+1)th term
3/4(14)th term = 10.5th term
(10th + 11th) / 2
= (31.7 + 32.3) / 2
= 32
IQR = Q3 - Q1
IQR = 32 - 28 = 4
Variance : (V) = Σ(x - m)²/n-1
[(32.3-29.05)^2 +(28.8-29.05)^2 + (29.1 - 29.05)^2 + (29.5-29.05)^2 + (30.8-29.05)^2 + (31.0-29.05)^2 + (17.5 - 29.05)^2 + (34.5-29.05) ^2 + (23.5-29.05)^2 + (33.0-29.05)^2 + (31.7-29.05)^2 + (28.6-29.05)^2 + (27.4 - 29.05)^2] / 12
Variance = 19.76
Standard deviation = sqrt(variance)
Standard deviation = sqrt(19.76)
Standard deviation = 4.45

A radioactive material disintegrates at a rate proportional to the amount currently present. If Q(t) is the amount present at time t, then dQ/dt =−rQ where r>0 is the decay rate.
Required:
If 100 mg of a mystery substance decays to 81.14 mg in 4 weeks, find the time required for the substance to decay to one-half its original amount.
Answer:
For the substance to decay to one-half of its original amount, it will take:
10.6 weeks.
Step-by-step explanation:
The decay rate = dQ/dt= -rQ
Where r > 0.
100 mg of a mystery substance decays to 81.14 mg in 4 weeks
This implies that it has decayed by 18.86 mg (100 - 81.14) in 4 weeks
The rate of decay per week = 4.715 mg (18.86 mg/4)
For the substance to decay to one-half of its original amount, i.e. 50 mg (100 mg/2), it will take 10.6 (4/18.86 * 50) weeks.
We can also determine the time it will take the substance to decay by working with the decay rate and the volume of decay, thus:
Decay rate = 4.715 / week
Decay volume = 50 mg (100 mg/2)
Time for 50 mg to decay = Decay volume/Decay rate
= 50 mg/4.715
= 10.6 weeks

There are 13 students in one line and 21 students in the other line. If the 5 points
Salome is 2 feet 5 inches tall. How many inches tall is Salome?
Answer:
Salome is 29 inches tall.
Step-by-step explanation:
Each feet has 12 inches.
Salome:
Salome is 2 feet 5 inches tall.
Since each has 12 inches, 2 feet = 2*12 = 24 inches
24 + 5 = 29 inches.
So Salome is 29 inches tall.

Let X have the probability mass function P(X = −1) = 1 2 , P(X = 0) = 1 3 , P(X = 1) = 1 6 Calculate E(|X|) using the approaches in (a) and (b) below. (a) First find the probability mass function of the random variable Y = |X| and using that compute E(|X|). (b) Apply formula (3.24) with g(x) = |x|. For reference, formula 3.24 states
Answer:
Step-by-step explanation:
From the given information:
Note that the possible values of Y are 0 and 1 because;
y = 0 if X = 0 and y = 1 if X = ±1
∴
[tex]P(Y =0) = P(X = 0) =\dfrac{1}{3}[/tex]
[tex]P(Y = 1) = P(X = -1 \ or \ 1) \\ \\ = P(X = -1) + P(X = 1)[/tex]
[tex]= \dfrac{1}{2}+ \dfrac{1}{6}[/tex]
[tex]=\dfrac{3+1}{6}[/tex]
[tex]= \dfrac{2}{3}[/tex]
b)
[tex]E(|X|) = \sum |x| P(X=x) = ( 1 \times \dfrac{1}{2}) + ( 0\times \dfrac{1}{3}) + ( 1 \times \dfrac{1}{6})[/tex]
[tex]= \dfrac{2}{3}[/tex]
How much time will it take for a car to travel 250meters if it is traveling at 70 m/s?
Answer: approximately 3.57 seconds
========================================================
Work Shown:
x = number of seconds
distance = speed*time
250 meters = (70 m/s)*(x seconds)
250 = 70x
70x = 250
x = 250/70
x = 3.57142857142858
x = 3.57
It takes approximately 3.57 seconds for the car to travel 250 meters, when it travels a constant speed of 70 meters per second.

Ginger buys lunch at school every day. She always gets pizza when it is
available. The cafeteria has pizza about 80% of the time.
Ginger runs a simulation to model this using a random number generator. She
assigns these digits to the possible outcomes for each day of the week:
• Let 0 and 1 = no pizza available
• Let 2, 3, 4, 5, 6, 7, 8, and 9 = pizza available
The table shows the results of the simulation,
08458 47165 68194 88490 01841
43226 12924 52568 93039 39406
What is the estimated probability that Ginger will eat pizza for lunch every day
next week?
A. 0.0
B. 0.2
C. 0.4
D. 0.8
Answer:
0.2
Step-by-step explanation:
43226 and 52568
The Probability that Ginger will eat pizza for lunch every day for next week is 0.2.
What is Probability?Probability is "possibility that deals with the occurrences random event. It values varies from 0 to 1".
According to the question,
Ginger assigns digits 0 and 1 = no Pizza available and also assign digits
2,3,4,5,6,7,8 and 9 = Pizza available.
The table shows the results of the simulation,
08458 this simulation contains digit '0' so there is no pizza.
47165 this simulation contains digit '1' so there is no pizza.
68194 this simulation contains digit '1' so there is no pizza.
88490 this simulation contains digit '0' so there is no pizza.
01841 this simulation contains digits '0 and 1' so there is no pizza.
43226this simulation contains no digits '0 and 1' so there is pizza available.
12924 this simulation contains digit '1' so there is no pizza.
52568 this simulation contains no digits '0 and 1' so there is pizza available.
93039 this simulation contains digit '0' so there is no pizza.
39406this simulation contains digit '0' so there is no pizza.
Total number of simulation = 10.
Formula for Probability = [tex]\frac{Number of favorable events }{Total number of outcomes}[/tex]
Probability of availability of Pizza = [tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex] = 0.2.
Hence, the Probability that Ginger will eat pizza for lunch every day for next week is 0.2.

an investor has 200k to invest among 4 possible investments including apple Inc. Each investment must be in units of 10k. Out of 200k, at least 50k must be invested to apple inc. If the whole 200k is invested, how many different investment strategies are possible
Answer:
The four investments are possible.
Step-by-step explanation:
Investor has 200k to invest,
The 4 investment are:
1. Apple inc
2. B inc
3. C inc
4. D inc
Assuming the other three investments are B, C and D.
If 50k is invested in Apple inc, how much is left?
200k -50k = 150k
This remaining 150k can shared equally amongst the other three investments ;
150/ 3 = 50
Therefore each investment will get 50k each.
