In studying different societies, an archeologist measures head circumferences of skulls Choose the correct answer below O A. The
Brums [2.3K]

Answer: The data are quantitative because they consist of counts or measurements.

Step-by-step explanation:

The definition of quantitative data says that if we can count or measure some thing in our data such as number of apples on each bag , length, width, etc then the data is said to be quantitative.

On the other hand  in qualitative data we can obverse characteristics and features but can't be counted or measured such as honesty , color, tastes etc.

Given : In studying different societies, an archaeologist measures head circumferences of skulls.

Since here we are measuring circumferences of skulls, therefor it comes under  quantitative data.

Hence, the correct answer is : The data are quantitative because they consist of counts or measurements.

Math problem help me out quick!
pentagon [3]

Answer:

h = 39

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the volume is 10000pi and the diameter is 32

The radius is 32/2 = 16

10 000 pi = pi (16)^2 h

Divide each side by pi

10 000 pi/pi = pi/pi (16)^2 h

10 000=  256 h

Divide each side by 256

10000/256 = 256h/256

39.0625 = h

To the nearest whole number

h = 39

Solve the equation for x 2/3x-1/9x + 5 = 20
Nady [450]

\bold{Answer}

\boxed{\bold{X \ = \ 27}}

\bold{Explanation}

  • \bold{Solve: \ \frac{2}{3}x-\frac{1}{9}x+5=20}

\bold{--------------------------}

  • \bold{Subtract \ 5 \ From \ Both \ Sides}

\bold{\frac{2}{3}x-\frac{1}{9}x+5-5=20-5}

  • \bold{Simplify}

\bold{\frac{2}{3}x-\frac{1}{9}x=15}

  • \bold{Multiply \ By \ LCM: \ LCM \ = \ 9}

\bold{\frac{2}{3}x\cdot \:9-\frac{1}{9}x\cdot \:9=15\cdot \:9}

  • \bold{Simplify}

\bold{6x-x=135}

\bold{5x=135}

  • \bold{Divide \ Both \ Sides \ By \ 5}

\bold{\frac{5x}{5}=\frac{135}{5}}

  • \bold{Simplify}

\bold{X \ = \ 27}

\boxed{\bold{Eclipsed}}
