The following data set is A population ⇒ answer A

Step-by-step explanation:

Lets revise the definition of each choice

1. A population, is a discrete group of people, animals or things that

can be identified by at least one common characteristic for the

purposes of data collection

2. A sample is just a part of a population

3. The parameter is a fixed measure which describes the target population

Parameter is a fixed and unknown numerical value

4. A statistic is a characteristic of a small part of the population

The statistic is a variable and known number which depend on the

sample of the population

∵ All of the teachers in Gwinnett County Public Schools fill out the

  survey

∴ The data set is population

The following data set is A population

g100num [7]

Answer:42.98

Step-by-step explanation:

Hf=√(11^2-8^2)

Hf=√(121-64)

Hf=√(57)

Hf=7.5

11/sin90 =7.5/sinG

Sin90=1

11/1=7.5/sinG

Cross multiply

11 x sinG=7.5 x 1

11sinG=7.5

Divide both sides by 11

11sinG/11=7.5/11

sinG=0.6818

G=sin(inverse)(0.6818)

G=42.98

Answer:

Height is 21cm

Step-by-step explanation:

Volume of the cylinder = 1029pi

Base area = 7x7xpi = 49pi

Therefor the height = 1029pi/49pi=1029/49 = 21cm

LMNP is a parallelogram.
Amanda [17]

A rectangle is a parallelogram with four right angles.

That's why in order to prove that LMNP is rectangle you have to show that LP is perpendicular to PN.

Solution:

The coordinates of vertices are L(-4,1), P(-3,-1) and N(3,2), then

\overrightarrow{PL}=(-4-(-3),1-(-1))=(-1,2),\\ \overrightarrow{PN}=(3-(-3),2-(-1))=(6,3).

Find the dot product:

\overrightarrow{PL}\cdot \overrightarrow{PN}=-1\cdot 6+2\cdot 3=-6+6=0.

Since the dot product of two vectors is equal to zero, these vectors are perpendicular.

LMNP is a parallelogarm, then

m\angle P=m\angle M=90^{\circ},\\ m\angle L=m\angle N=180^{\circ}-90^{\circ}=90^{\circ}.

You show that all angles are right, this means that parallelogram LMNP is a rectangle.

Answer: correct choice is D.
