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:

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.

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.

After 125% ,markup and a 10% discount, the price of a watch is $30.78 before tax, what was the whole price?

Answers

The 125% markup is $38.465 which I rounded it to $38.47 since it's money

To find the markup, you have to multiply 1.25 by 30.78 which you get $38.47 and then add it by $30.78 which you get $69.24

Then you multiply 10% or .10 by 69.24 which you get $6.92.

Finally, you just subtract $6.92 from $69.24 and you get the price of the watch which is $62.32

A 1350 kg car travels at 12 m/s. What is it's kinetic energy

Answers

energy is always transformed from one form to another

energy is not created nor destroyed

so when a car starts moving the chemical potential energy of the car is converted to kinetic energy

kinetic energy is the energy that moving objects possess

kinetic energy formula is as follows

Kinetic energy = 1/2 mv²

where m - mass

v - velocity

substituting these values


K.E = 1/2 x 1350 kg x (12 m/s)²

= 1/2 x 1350 x 144 = 97200 J

the kinetic energy of the car is 97.2 kJ

Hello!

A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?

We have the following data:  

m (mass) = 1350 kg  

v (velocity) = 12 m/s  

KE (kinetic Energy) = ? (in Joule)  

Formula to calculate kinetic energy:

\boxed{KE = (1)/(2) *m*v^2}

Solving:

KE = (1)/(2) *m*v^2

KE = (1)/(2) *1350*12^2

KE = (1)/(2) *1350*144

KE = (194400)/(2)

\boxed{\boxed{KE = 97200\:Joule}}\:or\:\boxed{\boxed{KE = 97.2\:kJ}}\Longleftarrow(kinetic\:energy)\:\:\:\:\:\:\bf\blue{\checkmark}
