Answer:

D.

Step-by-step explanation:

7 5/6 - 9 3/4 = −1 11/12

(-7 5/6) + (-9 3/4) = −17 7/12

(-7 5/6) * 9 3/4 = -76 3/8

(-7 5/6) / (-9 3/4) = 94/117

This is easy to figure out at a glance, but I thought whole answers would be easier to understand.

So basically, the equations two negatives are better off being crossed off if negatives are being added together, multiplied together, or multiplied by a positive number. Negative divided by a negative will be the greatest answer, because it will lead to a positive most of the time.

If students’ scores were normally distributed and the mean was 200 with a standard deviation of 40, then what is the probability
Sonja [21]

Answer:

  84%

Step-by-step explanation:

The empirical rule tells you that 68% of the standard normal distribution is within 1 standard deviation of the mean. The distribution is symmetrical, so the amount in the lower tail is (1 -68%)/2 = 16%.

Since the number you're interested in, 240, is one standard deviation above the mean (200 +40), the percentage of interest is the sum of the area of the central part of the distribution along with the lower tail:

  68% + 16% = 84%.

Find the thirteenth term of an arithmetic sequence if the first term is 3 and the common difference is 3
lesya692 [45]

Answer:

39

Step-by-step explanation:

Formula for the nth term (an) = a1 + d(n - 1)  where a1 = the first term and d = common difference.

So here the 13th term = 3 + 3(13 - 1)

= 3 + 3*12

= 39  (answer).
