Answer:
The value is a statistic because the 6,076 adults in public restrooms are a sample
Step-by-step explanation:
A measure that is calculated from a sample is known as sample statistic.
A study conducted and for the study 6076 adults are selected to inquire about the hand washing habit of adults. The selected 6076 adults are a sample and for this sample we computed the average 23% which demonstrates that 23% of adults did not wash their hands before exiting. So, a statistic is 23% and 6076 adults are a sample.
Answer:
165 combinations possible
Step-by-step explanation:
This is a combination problem as opposed to a permutation, because the order in which we fill these positions is not important. We are merely looking for how many ways each of these 11 people can be rearranged and matched up with different candidates, each in a different position each time. The formula can be filled in as follows:
₁₁C₃ = ![\frac{11!}{3!(11-3)!}](https://tex.z-dn.net/?f=%5Cfrac%7B11%21%7D%7B3%21%2811-3%29%21%7D)
which simplifies to
₁₁C₃ = ![\frac{11*10*9*8!}{3*2*1(8!)}](https://tex.z-dn.net/?f=%5Cfrac%7B11%2A10%2A9%2A8%21%7D%7B3%2A2%2A1%288%21%29%7D)
The factorial of 8 will cancel out in the numerator and the denominator, leaving you with
₁₁C₃ = ![\frac{990}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B990%7D%7B6%7D)
which is 165
Answer:
10
Step-by-step explanation:
(U can do mental calculation and guess it will be 10 ..) or else ....
Constant(k) = xy
k= 5 x 20
k= 100
Constant(k) = xy
100 = xy
100 = 10y
y= 100/10 = 10
= 10
I hope im right!!
Set 3x=210
We find that x=70
We then do 6•70 to find how many voted in total
Answer-420 total people voted
Answer:
Step-by-step explanation:
They have different y intercepts.
They have the same slope.
Here are 2 examples
y = 3x + 5
y = 3x + 19
The slopes are both three. The y intercepts are 5 for the top equation and 19 for the bottom equation.
They are both lines. That means their domain is -infinity <x < + infinity
Their range is - infinity <y < + infinity.
We are excluding examples like x = 3 and x = 5 and y = 1 and y = 3.
It is true that they both are parallel in both cases, but the discussion for each pair is a little different.
