it is a bracket used in maths
It seems that "d" or the common difference is a number that makes the sequence go into the larger positive realm of numbers. Therefore, 2*(7+30d)=7+80d. d=35/100. Now just do 7 + 40(35/100) = 21. 21 is your answer!
Answer:
y=-x-4
Step-by-step explanation:
You can write the equations in point-slope form first.
1) y+3=-(x+1)
2) Then you can convert it into slope intercept form
3) y=-x-1-3
4) y=-x-4
Answer:
A population in which the characteristic of interest is a discrete or continuous quantitative variable with an approximately symmetric and meso-curt distribution is appropriate to use the mean.
A population in which the characteristic of interest is a discrete or continuous quantitative variable with a slightly symmetric distribution or with extreme values is appropriate to use the median.
A population in which the characteristic of interest is a qualitative variable is appropriate to use fashion.
It is not appropriate to use the mean if extreme values are present.
It is not appropriate to use the median if there are several different values with high frequency.
It is not appropriate to wear fashion if the distribution is very skewed asymmetrically.
A frequent problem arises when it is desired to establish the sampling frame, that is, a list of the individuals in the population.
Example: Establish the characteristics of households with children under two years. It was solved by sampling in two phases, identifying in a first phase the sampling frame.
Step-by-step explanation:
Answer:
11 packs
Step-by-step explanation:
At least 60 and less than 90 will make it 60-89
<u><em>So, </em></u>
60-89 has 11 packs
