Yes, the samples are likely to be representative of all teachers and non-teachers in the state.
Statistical measure of central tendencyThe median, in similarity with the mean is a statistical measure of central tendency.
Since, the double box-and-whisker plot shows the distribution of sample medians, it follows that the samples are likely to be representative of all teachers and non-teachers.

Point L is on line segment KM. Given LM = 5 and KM=9, determine the length KL.
Answer:
KM=LM+KL. If KM is 9 and LM is 5, then KM-LM=KL. So 9-5=4. KL is 4.
Step-by-step explanation:
The value of KL will be equal to 4 in the line segment KM.
What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that point, L is on line segment KM. Given LM = 5 and KM=9. The value of the line segment KL will be calculated as below:-
KM = LM + KL.
If KM is 9 and LM is 5, then,
KM-LM=KL.
KL = 9-5=4.
KL = 4
Therefore, the value of KL will be equal to 4 in the line segment KM.

You're an automotive body repairer who is writing an estimate for a customer. You
figure the repair work will cost about $450.00 before tax. If the tax rate is 6%, how
much will the customer pay after tax?
$477.00
$720.00
$588.00
Answer:
$100.70
Step-by-step explanation:
The difference between the total price ($434.50) and the sales price ($415) is the tax ($19.50). To find the sales tax as a percentage of the sales price, divide the sales tax by the sales price and then multiply by 100:

Solution:
Note that:
Circumference = 50.24 ft = 2πr = πdDia. = 16 ft.Divide the diameter both sides.
50.24 ft = πd=> 50.24/d ft = πd/d=> 50.24/d ft = πSubstitute the diameter in the equation.

Answer:
13√2
Step-by-step explanation:
The longest segment that can be drawn is a "diagonal" connecting two opposite "corners" at the top and bottom.This is similar to finding the length of a diagonal of a rectangle using the Pytagoren Theorem. However, this distance is in 3-space and is given by:d =√(152 + 82 + 72) = √338 = √(169 * 2) = 13√2 cm.

The GCD and LCM of three numbers are 3 and 1008 respectively.If two of the numbers are 48 and 72.Find the least possible value of the third number
Answer:
21
Step-by-step explanation:
We decompose prime factors of 48, 72, and 1008
48=2*2*2*2*3
72=2*2*2*3*3
1008=2*2*2*2*3*3*7
Let's compare 48, 72 with GOD(3) and LCM(1008), we can find that there must be at least 2 prime factors in the third number that is 3 and 7.
And let's find out the LCM of 48 and 72. Quite obvious the answer is 144.
Since the LCM should be the consequence of 144 multiplied by another prime factor.
Then let's try 144*7. Amazingly 144*7=1008. DONE!
The population of Florida has increased, on average, at a rate of 8% per year since 1953. In 1993, the population of Florida was 13 million.
What was the population in 1953?
*show work & will give brainliest*
Answer:
598,402
Step-by-step explanation:
Let y = population at year x
x is the number of years since 1953, so for 1993, x = 40
a = population in 1953
y = a(1.08)^x
In 1993, the population is 13,000,000, so y = 13,000,0000 when x = 40.
13,000,000 = a(1.08)^40
13,000,000 = 21.7245a
a = 598,402

This is how i think you do this
Step-by-step explanation:
6439e^.04x8= 8867.32, or
e^.04= 1.0408 = 6439 x (1.0408^8) = 8,867.33.
the first one would be if she is receiving multiple payments ove the year, and the second one is just the "4% commended annually per year". its been a minute since ive actually had to do this, but that seems right to me. so she will have enough.
Which quadratic equation is equivalent to (x – 4)2 – (x – 4) – 6 = 0?
