Answer:

The answer is stratified sampling.

Step-by-step explanation:

Miranda divides up her day into three​ parts: morning,​ afternoon, and evening.

She then measures her heart rate at 2 randomly selected times during each part of the day.

This sampling method is Stratified sampling.

This is because Miranda created separate groups and took samples from each group.

Stratified sampling is defined as dividing the population into separate groups or strata and then drawing a sample from each group.

Is 4/6 greater than 4/7?
dexar [7]
Yes, to make it simpler and easier to tell, you could put both these fractions into decimals or percentages.

4/6 as a decimal would be .66 or 66%
4/7 as a decimal would be .57 or 57%

Hope this helps! :}

MAXImum [283]

Answer:An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ... ℤ is a subset of the set of all rational numbers ℚ, which in turn is a subset of the real numbers ℝ.

Which is the graph of f(x) = -(x + 3)(x + 1)?
ch4aika [34]

Answer:

Step-by-step explanation:

x intercepts are -3,-1

f(x)=-(x²+x+3x+3)=-(x²+4x)-3=-(x²+4x+4-4)-3=-(x+2)²+4-3

or f(x)=-(x+2)²+1

vertex is (-2,1)

so it is an inverted  parabola with vertex (-2,1) and x-intercepts (-3,0) and (-1,0)
