Solve (16×^3-3×^2+43×-5)÷(×^2-2)

Oksana_A [137]

Answer:

3872/(x^2 - 2)

Step-by-step explanation:

Simplify the following:

(16^3 - 3^2 - 5×43)/(x^2 - 2)

3^2 = 9:

(16^3 - 9 - 5×43)/(x^2 - 2)

16^3 = 16×16^2:

(16×16^2 - 9 - 5×43)/(x^2 - 2)

| 1 | 6

× | 1 | 6

| 9 | 6

1 | 6 | 0

2 | 5 | 6:

(16×256 - 9 - 5×43)/(x^2 - 2)

16×256 = 4096:

(4096 - 9 - 5×43)/(x^2 - 2)

43 (-5) = -215:

(4096 - 9 + -215)/(x^2 - 2)

4096 - 9 - 215 = 3872:

Answer: 3872/(x^2 - 2)

Lelechka [254]

Answer:

52.1

Step-by-step explanation:

When dividing decimals, convert the divisor to an integer by moving the decimal point a suitable number of places. Move the decimal point in the dividend the same number of places in the same direction. Make sure the decimal point in the quotient is aligned with the new location of the decimal point in the dividend.

36.47 ÷ 0.7 = 364.7 ÷ 7 = 52.1

ANEK [815]

Answer:

mean =median, so the data is symmetrical

Step-by-step explanation:

Given

Data set= {10,5,8,10,12,6,8,10,15,6,12,18}

Mean= Sum of data points/number of data points

= (10+5+8+10+12+6+8+10+15+6+12+18)/12

=10

Median= mid value

={5,6,6,8,8,10,10,10,12,12,15,18}

Middle values are 10 and 10

Median = 10+10/2

= 20/2

= 10

Mean= median so there will be no skewness and the distribution is equal !
