Which statements are true? Check all that apply

please help me and before you try to answer the height is not 8 in but the volume is 25.12 in if that helps thank you <3

DochEvi [55]

Answer:

25.12 in^3.

Step-by-step explanation:

Volume of the cylinder = 3.14 * r^2 * h

= 3.14 * 2^2 * 8

The volume of the preserve

= 1/4 * 3.14 * 4 * 8

= 25.12 in^3.

mina [271]

Answer:

centre = ( $\frac{3}{2}$ , 1 )

Step-by-step explanation:

using the midpoint formula

midpoint = [ $\frac{1}{2}$ (- 1 + 4), $\frac{1}{2}$ (5 - 3) ] = ( $\frac{3}{2}$ , 1 )

Which additional information could be used to prove that the triangles are congruent using AAS or ASA? Check all that apply.

Ad libitum [116K]

Consider the given triangles.

Given: $\angle C \cong \angle Q$

ASA congruence criterion states that if two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

AAS congruence criterion states that if two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

Consider the first part:

1. In triangles ABC and QPT

If we take $\angle B \cong \angle P , BC \cong PQ$ along with the given condition.

Then the triangles are congruent by ASA congruence criterion.

2. If we take $\angle A \cong \angle T$ and $AC= TQ=3.2$ along with the given condition.

Then the triangles are congruent by ASA congruence criterion.

3. As, $\angle C \cong \angle Q$ , $\angle A \cong \angle T$ and $\angle B \cong \angle P$ , so the triangles can not be congruent.

4. If we take $\angle A \cong \angle T$ and $BC \cong PQ$ along with the given condition.

Then the triangles are congruent by AAS congruence criterion.

5. If we take AC=TQ=3.2 and CB=QP=3.2 along with the given condition, then the triangles are congruent but by SAS congruence criteria neither by ASA nor AAS congruence criterion.

A city has designed a survey to collect information about residents’ opinions about city services. Which of the following descri

Maslowich

Bias refers to scenarios which might affect the ability of a statistical experiment to generalize, hence affecting the validity of research. Non-response bias occurs when majority of subjects fail to respond during a survey. Hence, a likely scenario is ; surveys were mailed to 500 people, and 200 of the surveys were completed and returned.

Non - response bias has to do with a situation whereby a large percentage of the selected samples from a population do not respond or fail to participate in the experiment or survey.

If 200 surveys were returned, then 300 of the sample participants did not respond. Which means 60% of the sample are non-responsive.

Therefore, a scenario where surveys were mailed to 500 people, and 200 of the surveys were completed and returned exemplifies a non - response bias.
