We have that for the Question ,it can be said that the next 3 sequence is

Respectively

Generally

We notice that the difference between numbers in the sequence rises by 4

therefore

For the first differ

9-2=7

7+4=11

Hence

11+9=20

Generally

for the sixth value

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.

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.

Answer:

13 tens

Step-by-step explanation:

Given data

We are given that the traveled 1,355 miles of distance

Hence the number of tens of hundred is

=1,355/100

=13.55

Hence in all, there are 13 tens of hundreds

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.

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.

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]

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.

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

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
