A school principal wants to determine which type of speaker the students prefer to invite to an assembly for the entire student population. Which survey method would produce the best representative sample----A) survey every fifth person who shops at a mall B) survey all of the students on the student council C) Survey every tenth student entering the school one morning D) survey all the students who went to the last basketball game. PLS HELP

Answers

Answer 1
Answer:

Answer:

Option C is correct.

Step-by-step explanation:

C- Survey every tenth student entering the school one morning.

This is because the survey is related to the entire student population of a school as they want to know which type of speaker the students prefer to invite to an assembly.

Reasons for incorrect options:

Option A is not true as it will relate to a mall survey. Option B is also incorrect as it will only survey few students of a student council that cannot represent a whole population. Option D is related to basketball survey, it has nothing to do with any speaker chosen for an assembly.

Answer 2
Answer: Since the question asks for the best representative sample of the entire student population, the answer is
C) survey every tenth student entering the school one morning.

Paolo pays $244 for 5 identical calculators. About how much does Paolo pay for one calculator?

Answers

About $50 because if you round 244 to 250 (because 250 is easier to dived into 5 and is close to 244). Then you dived 250 into 5 which equals 50.
so you are going to add and it will be 30 for your answer

What is the answer to the equation 5+2(x-1)=12

Answers

5+2(x-1)=12 \n \n 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \n \n 2(x - 1) = 7 \ / \ simplify \n \n x - 1 =  (7)/(2) \ / \ divide \ each \ side \ by \ 2 \n \n x =  (7)/(2)  + 1 \ / \ add \ 1 \ to \ each \ side \n \n x =  (9)/(2) \ / \ simplify \n \n

So, the answer to this problem is x = 9/2 or x = 4.5.
5+2(x-1)= 12
So you need to get rid of parentheses, which is that you have to distribute.
5+2x-2= 12
-5             -5    (Inverse)
2x-2= 7
    +2  +2         (Another inverse)
2x= 9
2      2       (Divide)

x= 4.5
----------------------
Check
5+2(4.5-1)=12
5+2(3.5)=12
5+7=12
12=12

A landscaper is designing a flower garden in the shape of a trapezoid. She wants the length of the shorter base to be 3 yards greater than the height, and the length of the longer base to be 5 yards greater than the height. For what height will the garden have an area of 360 square yards? Round to the nearest tenth of a yard.17.1 yards
34.2 yards
39.2 yards
152.6 yards

Answers

Correct Answer:
Option A. 17.1 Yards

Solution:
Let the height of trapezium is x yards. According to the given data, we can express the lengths of bases in terms of height.

The short base is 3 yards greater than the height, so measure of short base will be (x+3) yards.

The longer base is 5 yards greater than the height, so measure of longer base will be (x+5) yards.

Area of trapezium is given to be 360 square yards.

Area of trapezium = 0.5 x (Height) x (Sum of Bases)

Using the values, we get:

360=0.5(x)(x+3+x+5) \n \n 720=x(2x+8) \n \n 2 x^(2) +8x-720=0 \n \n 2( x^(2) +4x-360)=0 \n \n x^(2) +4x-360=0 \n \n x= (-4+- √(16-4(1)(-360)) )/(2) \n \n x= (-4+- √(1456) )/(2) \n \n x = 17.1 , -21.1

Since the height cannot have a negative value, we conclude that the height of trapezium rounded to nearest tenth of a yard will be 17.1 yards.
