The distribution of the amount of money spent by students for textbooks in a semester is approximately normal in shape with a me

vladimir2022 [97]

Answer:

b. between 195 and 275 dollars.

Step-by-step explanation:

The standard deviation rule, or the 68-95-99.7 rule, states that, for a normally distributed random variable X:

68% of the measures are within 1 standard deviation of the mean

95% of the measures are within 2 standard deviations of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean 235, standard deviation 20.

According to the Standard Deviation Rule, in a semester, most (95%) of the students spent on textbooks:

Between 235 - 2*20 = 195 dollars and 235 + 2*20 = 275 dollars.

So the correct answer is:

b. between 195 and 275 dollars.

Write a short description of the pattern in this sequence of six numbers and then follow that pattern to write the next three nu

denpristay [2]

Answer: The next three terms are $\dfrac{7}{23},\dfrac{8}{26},\dfrac{9}{29}$

Step-by-step explanation:

Since we have given that

$\dfrac{1}{5},\dfrac{2}{8},\dfrac{3}{11},\dfrac{4}{14},\dfrac{5}{17},\dfrac{6}{20}$

After analyzing the above pattern, we get that

In numerator , numbers are run in consecutive manner.

In denominator, number is added to 3 to get the next term.

So, the general form would be $\dfrac{n}{3n+2}$

So, the next three terms would be

$\dfrac{7}{3\times 7+2}=\dfrac{7}{23}\\\\\dfrac{8}{3\times 8+2}=\dfrac{8}{26}\\\\\dfrac{9}{3\times 9+2}=\dfrac{9}{29}$

Hence, the next three terms are

$\dfrac{7}{23},\dfrac{8}{26},\dfrac{9}{29}$
