The 2000 CDC growth charts were developed using a reference population of infants. A pediatrician looks up one of the charts and

finds that the 10th percentile for weights of baby boys at 3-1/2 months is 10.9 pounds. This means that _______ of the 3-1/2-month-old baby boys in the reference population weigh 10.9 pounds or less, and ________ of these baby boys weigh 10.9 pounds or more.

Answer:

The 2000 CDC growth charts were developed using a reference population of infants. A pediatrician looks up one of the charts and finds that the 10th percentile for weights of baby boys at 3-1/2 months is 10.9 pounds. This means that *** about 10%*** of the 3-1/2-month-old baby boys in the reference population weigh 10.9 pounds or less, and ***about 90%*** of these baby boys weigh 10.9 pounds or more.

Step-by-step explanation:

Percentiles indicate the position or standing of a value as compared to the general set of values in the same sample space. They indicate the values below which a certain percentage of the data in a data set is found.

The nth percentile of a set of data is the value at which n percent of the data is below it.

Like in this example, the 10th percentile is the value (or score) below which 10% of the observations may be found. Similarly, 90% of the observations are found above the 20th percentile.

The trapezoid and kite have been broken for you.
faltersainse [42]

Answer:

  • 20 m²
  • 21 m²
  • less than

Step-by-step explanation:

<u>Trapezoid</u>

The trapezoid has been broken into two triangles and a rectangle. The two triangles both have the same dimensions, so both have the area ...

  A = (1/2)bh = (1/2)(2 m)(5 m) = 5 m²

The rectangle has area ...

  A = bh = (2 m)(5 m) = 10 m²

So, the total area of the trapezoid is ...

  trapezoid area = 5 m² +10 m² +5 m²

  trapezoid area = 20 m²

__

<u>Kite</u>

The kite has been broken into two triangles, so the area of each of them is ...

  A = (1/2)bh

  A = (1/2)(7 m)(3 m) = (21/2) m²

Then the area of the two halves of the kite will be ...

  kite area = 2 × (21/2 m²)

  kite area = 21 m²

__

The area of the trapezoid is <u>1 m² less than</u> the area of the kite.

Find an ordered pair to represent a in the equation<br> a=2b+c if b=(6,3) and c=(-4,8)
zaharov [31]

Answer:

The ordered pair to represent a in the equation a=2b+c if b=(6,3) and c=(-4,8) is: a=(8,14)

Step-by-step explanation:

b=(6,3)

c=(-4,8)

a=2b+c

Replacing b and c in the equation above:

a=2(6,3)+(-4,8)

Multiplying:

a=(2*6,2*3)+(-4,8)

a=(12,6)+(-4,8)

Adding:

a=(12+(-4),6+8)

a=(12-4,14)

a=(8,14)
