Answer:
<h2>4.4cm</h2>
Step-by-step explanation:
in this problem we are expected to solve for the diameter of each circle pendant and add them to get the height of the complete pendant.
we know that the circumference is given as
C=πd
for the small circle
C=6cm
6=3.142d
d=6/3.142
d=1.9cm
for the big circle
C=8cm
8=3.142d
d=8/3.142
d=2.5cm
the height then is 1.9+2.5=4.4cm
Answer:
(9,4)
Step-by-step explanation
You can use substitution:
plug in y=2x-14 into 3x-2y=19
3x-2(2x-14)=19
then simplify it
3x-4x+28=19
-x+28=19
-x=-9
divide everything by -1
x=9
Then plug in x=9 into the equation to find y
y=2x-14
y=2(9)-14
y=18-14
y=4
To check your answer plug x and y back into the equation
3(9)-2(4)=19 check
4=2(9)-14 check

Answer:
Population is all students from grades 3-12.
Sample is the students who participated in the survey.
Step-by-step explanation:
Given : A survey of third- to twelfth-grade students with a sample size of 2026 found that they devoted an average of 1 hour and 46 minutes per day to using entertainment media.
To find : Identify the population and the sample.
Solution :
The population is defined as it contain all individuals which we want to collect the information.
So, the population consists of all third- to twelfth grade students.
Therefore, Population is all students from grades 3-12.
The sample is defined as a part of population of which information was actually collected.
So, the sample is only the respondents in the survey conducted in 2026.
Therefore, Sample is the students who participated in the survey.
