Answer:
with which one
Step-by-step explanation:
Answer:
C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
Step-by-step explanation:
Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.
Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.
Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.
Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.
The area is 6 and 4, and the perimeter is 8 and 4
Given:
Height of access ramp = 6 foot
Ramp ends at a point 40 feet away along the ground.
To find:
The angle of depression in nearest tenth of a degree.
Solution:
Using the given information, draw a figure as shown below.
In a right angle triangle,
In triangle ABC,
Taking tan inverse on both sides.
Therefore, the angle of depression is 8.5 degrees.
<h2>Quick answer :</h2>
<h3>(A) = $4042.50 </h3><h3>(B) = $14520.50</h3>
<h2><em><u>Solution with steps</u></em> : </h2><h2><u>Solution (A)</u> : </h2>
Money invested by a man = $10,500
No.of years for which he invested his money = 7
Rate of interest = 5.5%
We know that :
Principal = 10500
Rate = 5.5%
Time = 7 years
Simple interest the man payed :
Therefore, the simple interest payed by the man = <u>$4042.50</u>
<h2><u>Solution (B)</u> :</h2>
Money invested by the man (principal) = $10,500
The simple interest he payed = $4042.50
We know that :
The amount the man collected after a period of 7 years :
Thus, amount = $14520.50
Therefore the amount he collected after a period of 7 years = <u>$14520.50</u>
