How do you think statistics may at times not say something? How can a well-designed study be used to carefully say everything that is important about a population? Is it possible to do so?
Answers
Answer:
While statistics are extremely valuable, they are also notorious for being a means that people use to make false and misleading arguments. Also far too often statistics are obtained by taking a sample from a larger group and assuming the whole group has the same characteristics as the sample.
A sample provides a smaller set of the population for review, that delivers data that is useful to represent the whole population. Surveying a smaller sample, as opposed to the entire population, can save precious time for researchers and offer urgent data.

The rectangle below has an areas of x^2+8x+15 square metres and a width of x+3 meters what expression represents the length of the rectangle
Answers
Answer: x+5 or ((x^2+8x+15)/(x+3))
Step-by-step explanation: First let's assign our variables.
x^2+8x+15 = Area
X+3 = Width
? = Length
If the equation of a=lw, then we can substitute in our variables.
a=lw
x^2+8x+15= L (x+3)
Now we must isolate L.
Divide both sides of the equation by 'x+3'
x^2+8x+15= L (x+3)
x+3 x+3
x+5= L

Hello There!
Angle E and angle D are supplementary angles meaning that the sum of the two angles equals 180
So we setup an equation
180=2x+12+5x
step 1 combine like terms
5x+2x=7x
now we have
180=7x+12
step 2 subtract 12 from each side
12-12 cancels out
180-12=168
now we have
168=7x
step 3 divide each side by 7
7x/7=x
168/7=24
we're left with~ x=24
