= -2(1/3x)
=-2/3x
you multiply the bracket first and then times -2.
The rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. I'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
Answer:
By knowing the standard deviation, one gets the idea of how the value is scattered or dispersed about the mean.
Step-by-step explanation:
Let us first define standard deviation.
As it is known that the standard deviation is a measure of dispersion which express the spread of observation in terms of the average of deviations of observations from some central values.
Measure of dispersion gives us an idea about homogeneity or heterogeneity of the distribution.
Standard deviation is supposed almost an ideal measure of dispersion except the general nature of extracting the square root.
Thus for the given question, if we want to compare the two different groups of students whose mean score is 85. Here the standard deviation for both the groups interprets an idea about how the individual score for each group scattered or varied about the mean score i.e. 85.
Answer:
112 minutes
Step-by-step explanation:
Suzanne can put up 20 feet of fencing in 64 minutes.
We need to find minutes it will take to put up 35 feet of fencing.
20 feet = 64 minutes
1 feet = (64/20) minutes
For 35 feet,
So, it will take 112 minutes to put up 35 feet of fencing.
2/56 divid it by 2 because 2 can go into both of them and you get 1/28
