A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 28 boys into
two equal sized groups, where Group 1 was given the energy drink and Group 2 was
not. The 100 meter race times were recorded during practice and shown in the table
below.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

they used 313 gallons of paint

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
