What is the answer to -12 = 4(f-6)
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

Right triangle PQR is shown on the graph below. If the point (x, 7) lies on the line that goes through side of the trianglethen what should be the value of x?
A. -2
B. 5
C. -3
D. 3
Answer:
C. -3
Step-by-step explanation:
First, find the slope of side QR. Calculate the slope by finding the ratio of the difference between the y-coordinates and the difference between the x-coordinates of points Q and R.
The slope of side QR can be found as shown below.
Now, using the slope of side QR, draw a triangle RST similar to the right triangle PQR with S(x, 7) as one vertex.
Next, find the value of x as shown below.
Therefore, the value of x in the point (x, 7) is -3.

The illustration below is an example of a semi-regular tessellation.
A. True
B. False
The illustration below is a semi-regular tessellation is a false statement.
What is Tessellation?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.

A random sample of 144 observations has a mean of 20. The population standard deviation is known to equal 4.8. The 95.44% confidence interval for the population mean is
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.

A project consists of three tasks: A, B, and C. Task A is known to take five days for sure. Tasks B and C are each dependent on A. B takes five days. C takes seven days with a probability of 0.5 and three days with a probability of 0.5. What is the expected completion time of the project
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
What is the expected completion time of a task?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
