Answer:

Answer would be 0.67 years, 13.3 years and 1.5 years.

Step-by-step explanation:

It is given Mean = 13.3, Median = 13.5, Mode = 14, MAD = 0.67

Now we complete each statement from the given data.

Here Mean absolute Deviation is 0.67 which shows how far or how near  the values to the mean value.

1.  On average, the age of a student is about  0.67 year(s) away from  13.3   year(s).

2. If the MAD for another club was 1.5 years, then that club's ages would be 1.5 than the ages for this club.

He center of a circle represented by the equation (x + 9)2 + (y − 6)2 = 102 is
maksim [4K]

centre = ( - 9, 6)

the equation of a circle in standard form is

(x - a)² + (y - b)² = r²

where (a , b) are the coordinates of the centre and r is the radius

(x + 9)² + (y - 6)² = 102 is in this form

with centre = ( - 9 , 6 )

Solve for x 36x-6=16x+18x+2
Elodia [21]

Answer: X=4

Step-by-step explanation:

Pulling out like terms :

1.1     Pull out like factors :

  2x - 8  =   2 • (x - 4)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-4 = 0

Add  4  to both sides of the equation :

                     x = 4

One solution was found :

                  x = 4

According to historical records, the Great Pyramid of Giza was originally about 147 meters tall. Assuming it was built with its
vivado [14]

Answer:

115m

Step-by-step explanation:

Note that one of the face of a pyramid is a right angled triangle.

Since the pyramid was about 147m tall, the height of triangle will be 147m. If one of the faces is built with one of its faces at 52° to the incline, we can find the original length of one of its sides using SOH CAH TOA

tan(theta) = opposite/adjacent

Given theta = 52°, opposite = 147m (the side directly opposite the angle)

Substituting we have;

Tan52° = 147/adjacent

Adjacent = 147/tan52°

Adjacent = 114.8m

= 115m

Therefore 115m is the original length of one of its side

Find the area of the shaded sector.
Vladimir [108]

Given that,

Radius of the circle, r = 8.91 cm

Angle, \theta=81^{\circ}

To find,

The area of minor sector.

Solution,

The formula for the area of minor sector is given by the formula as follows :

A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{81}{360}\times \pi \times (8.91)^2\\\\A=56.11\ \text{cm}^2

So, the area of the shaded sector is 56.11\ \text{cm}^2.
