now.. if you notice, the exponent for the 1st term, is dropping on each term subsequently, start with highest, 9 in this case, and drops drops drops, till on the last term, will be 0
the exponent for the second term, starts off at 0, and goes up up and up on each term
that part is simple... now, the coefficient for them
the first one will have a coefficient of 1, so we can take a closer look at the 2nd instead
the coefficient for the second is 1* 9/ 1
(1) the coefficient of the current term, (9) the exponent of the 1st term, and (1) the exponent of the 2nd term on the next term
for example, how did we get 84 for the 4th term? (36 * 7) / 3 = 84
and so on for all subsequent terms
1-14, You're just dividing. Like #1, -14÷2=-7 (negative fourteen divided by two, equals negative seven). A positive and a positive make a positive, a negative and a positive make a negative, a negative and a negative, make a positive. The word problems your also dividing, for example, #15, -40÷4=-10. Use the numbers that are given to you.
Answer:
46
Step-by-step explanation:
We are given that a class's test scores are normally distributed with an average score of 60.
We know that the curve of a normal distribution is symmetric about its mean.
60-14=46
60+14=74
Hence, the point 46 lies to the left of the mean and 74 lies to the right of the mean, and the two points have the same function value.
