The answer is 3

Explanation: Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction. 3

Answer:

The expected completion time of the project is:

10 days.

Step-by-step explanation:

Duration of Task A = 5 days

Task B and C depend on Task A

This implies that Task A must be completed before Task B and C can be started.

To complete Task B will take 5 days

To complete Task C will take 5 days (7 * 0.5) + (3 * 0.5)

Since Task A takes 5 days and Tasks B and C depend on Task A and Task B takes 5 days and Task C takes expected time of 5 days, it means that the project can be completed in 10 days (5 + 5) if tasks B and C are simultaneously carried out.

The expected completion time of the project is

(i)10 days if B&C are mutually independent

(ii)15 days if B &C are mutually dependent

Expected completion time of a task= p1x1 + p2x2

Where

p1 & p2 are probabilities.

x1 and x2 are samples.

p1=p2=0.5

x1=7

x2=3

Expected completion time of task C= 0.5*7+0.5*3 = 5 days

Task B and C will be due till task A is not accomplished.

Total time to accomplish task A = 5 days

Total time  to accomplish task B= 5 days

Expected time to accomplish task C = 5 days

If tasks B and C are mutually independent

expected time to complete the project = 5+5=10days

If task C depends on task B

Expected time to complete the project = 5+5+5 = 15 days.

Therefore

The expected completion time of the project is

(i)10 days if B&C are mutually independent

(ii)15 days if B and C are mutually dependent

Answer:Y=2x-6

Step-by-step explanation:

The illustration below is a semi-regular tessellation is a false statement.

Tessellation is defined as the process of covering of a surface or a plane using the geometric shapes.

One geometric shape will not overlap with the other and there will not be any gaps in between.

There are regular tessellations as well as semi-regular tessellations.

Regular tessellations are the tessellations which are made using only a single type of the polygon to cover the entire surface.

Whereas in semi-regular tessellations, two or more regular polygons are used such that each vertex is the same to cover the surface.

Here, the illustration contains only one type of polygon which are tiled to each other with out any gaps.

It is actually regular tessellation.

Hence the statement that the illustration is semi-regular tessellation is incorrect.

Answer:

Step-by-step explanation:

-12 = 4(-6 + f)

-12 = (-6 * 4 + f * 4)

-12 = (-24 + 4f)

-12 = -24 + 4f

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-4f' to each side of the equation.

-12 + -4f = -24 + 4f + -4f

Combine like terms: 4f + -4f = 0

-12 + -4f = -24 + 0

-12 + -4f = -24

Add '12' to each side of the equation.

-12 + 12 + -4f = -24 + 12

Combine like terms: -12 + 12 = 0

0 + -4f = -24 + 12

-4f = -24 + 12

Combine like terms: -24 + 12 = -12

-4f = -12

Divide each side by '-4'.

f = 3

Simplifying

f = 3

Answer:

The population mean is 19.2 to 20.8.

Step-by-step explanation:

The formula of Confidence interval is

CI = mean ± z*[tex]\frac{s}{\sqrt{n} }[/tex]

where

n = sample size

s  = Population standard deviation.

mean = Sample mean

z(α/2) = Two tailed z-value for significance level of .

Given : Confidence level = 95.44% = 0.9544

Significance level =  α = 1-0.9544 = 0.0456

Now we Use standard z-value table  

z-value for Significance level of 0.0456 :

z(α/2) = z(0.0228) = 1.99 = 2(approximately)

And we are given

n=144

s = 4.8

mean = 20

so the required Confidence interval is

CI = 20± 2*[tex]\frac{4.8}{\sqrt{144} }[/tex]

     = 20 ± 2*[tex]\frac{4.8}{12}[/tex]

      = 20 ± (0.8)

      = (20-0.8, 20+0.8 )

       = (19.2 , 20.8)

Therefore the 95.44% CI value  for the population mean of 20 is 19.2 to 20.8.
