Using the test statistic formula, the test statistic is 7.3408.

In the given question,

We have to testing a claim about a population proportion of 0.2.

We have to find the test statistic given the following sample results:

Success (x) : 89

Sample Size (n) : 225

So estimation point,

p = x/n

p = 89/225

p = 0.396

We have to check the test hypothesis for:

H(0): P = 0.2

H(a): P > 0.2

Test Statistic Z = (p - P)/√P(1-p)/n)

Z = (0.396 - 0.2)/√(0.2(1-0.2)/225)

Z =0.196/√(0.2*0.8/225)

Z =0.196/√(0.16/225)

Z =0.196/√0.000711

Z =0.196/0.0267

Z = 7.3408

Hence, the test statistic is 7.3408.

The area of the shaded circular region is 197.82 unit².

The space a circle takes up on a two-dimensional plane is known as the area of the circle. The region contained within the circle's circumference or perimeter is another way to define the circle's area.  A = πr², where r is the circle's radius, is the formula for calculating a circle's surface area.

The radius of the inner circle = 9 units

So, the area of the inner circle is given by

a = πr²

= 3.14 × 9²

= 3.14 × 81

= 254.34 unit²

The radius of the outer circle = 12 units

So, the outer circle area is given by

A = πR²

= 3.14 × 12²

= 3.14 × 144

= 452.16 unit²

So, the area of the circular shaded region is given by

Area = area of the outer circle - an area of the inner circle

= 452.16 - 254.34

= 197.82 unit²

By using the rectangle, we proved that area of triangle is half the area of rectangle that is 1/2 (base×height).

To Prove:- Area of a triangle= 1/2 (base×height)

Diagonals of a rectangle divide it into two parts of equal areas.

Let  ABCD  be a rectangle.

In ΔABC and ΔADC,

                                         AC=AC

By Alternate Interior Angles:

                                    ∠BAC=∠CAD

                                    ∠BCA=∠CDA

Hence, ΔABC≅ΔACD

                               ∴ar(ΔABC) =ar(ΔACD)

Let ΔABC,

We draw a line AD perpendicular to BC, line EF parallel to BC passing through A and lines BE and CF , perpendicular to BC passing through B and C respectively.

In rectangle ADBE,

we get,

                     ar(ΔABE)=ar(ΔADB)

Similarly, in rectangle ADCF,

                     ar(ΔADC)=ar(ΔACF)

Now, area of rectangle BCFE, from axiom,

                               =(length)⋅(breadth)

                               =AB⋅BC

                              =AD⋅BC

Also,

ar(BCFE)

                                   =ar(ADBE)+ar(ADCF)

                                   =2⋅ar(ΔADC)+2⋅ar(ΔADB)

                                   =2(ar(ΔADC)+ar(ΔADC)

                                   =2(ar(ΔABC))

From (1) and (2),

                                   2(ar(ΔABC))=AD⋅BC

                                    ar(ΔABC)=1/2AD⋅BC

                                   ar(ΔABC)=1/2(base)⋅(height)

The answer is, 720 minutes ahead of clock b will clock a be 48 hours later.

How to read time?

The three hands on the clock's face display the time in hours, minutes, and seconds. The hour hand, minute hand, and second hand all display the hours, minutes, and seconds respectively.

A clock has 12 large divisions that are marked. Each of the large divisions has five smaller divisions. For a minute, the little separation remains in place. Five minutes have elapsed once the minute hand transitions from one large division to the next.

we will get after 360 hrs, clocks A and B will both have the same time.

Clock A will show the correct time, whereas clock B will be running faster by 12 hrs and therefore show the same time. A clock that moves forward by 12 hours will appear to display the same time once more. 12hours*60minutes/hour= 720 minutes.

Hence the answer will be 720 minutes.

Divide:

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.

Graph:

Graph means a pictorial representation or a diagram that represents data or values in an organized manner.

Given,

Question 6

Six customers are buying gasoline at Miguel's Gasoline Station. The number of gallons bought and the total cost of their purchases are plotted on the graph.

Here we need to find the price per gallon at Miguel's Gasoline Station.

In order to find the price, we have to take the points from the given graph.

Then we the points as, (4,10) and (9, 22)

By looking in the graph, the plotted points will form the straight line on the graph.

So, we have to use the formula for straight line to find the cost on one liter,

For, that we have to find the following,

m = (22 - 10) / (9 - 4)

m = 12/5

And the value of y intercept is,

10 = 12/5 (4) + c

50 = 48 + c

c = 2

The equation for the graph is y = 12/5x + 2

Therefore, the cost of 1 liter of the material is,

y = 12/5 (1) + 2

y = 12/5 + 2

y = 12+10/5

y = 22/5

Therefore, the cost is 4.4.

Answer:

  2.76×10^-3 m/s²

Step-by-step explanation:

You want to know the acceleration of the moon toward the Earth, given its distance is 3.8×10^8 meters, Earth's mass is 5.98×10^24 kg, and the gravitational constant is 6.673×10^-11 N·m²/kg².

The acceleration of one body by another is ...

  a = GM/r²

where G is the gravitational constant, M is the body creating the gravitational field, and r is the distance between the masses.

  a = (6.673×10^-11)(5.98×10^24)/(3.8×10^8)² N/kg

  a = (6.673·5.98/3.8²)×10^(-11+24-16) m/s² ≈ 2.76×10^-3 m/s²
