The mean of 8 math quiz scores is 88. If the first seven scores are 85,70,92,85,91,100, and 88, what is the eighth quiz score? U

Answer:

Step-by-step explanation:

The mean of a list of numbers is the sum of the numbers divided by the count of the numbers in the list.

In this case, representing the eighth score with x, the mean is (611+x)/8

Solving for the mean:

88=(611+x)/8

Multiply both sides by 8

8*88=611+x

704=611+x

704-611=x

x=93

1. In how many ways can a committee of eight people to be formed from a group of 6 male, 5 female and 4 students if there are no

NeX [460]

Answer:

The number of ways is 6435

Step-by-step explanation:

Given

$Male = 6$

$Female = 5$

$Students = 4$

Required

Number of ways a group of 8 can be formed

Here, I'll assume each category of people are distinct:

Hence;

$Total = Male + Female + Students$

$Total = 6 + 5 + 4$

$Total = 15$

Number of ways is then calculated as follows:

$^nC_r = \frac{n!}{(n - r)!r!}$

Where

$n = 15\ and\ r = 8$

So, we have:

$^{15}C_8 = \frac{15!}{(15 - 8)!8!}$

$^{15}C_8 = \frac{15!}{7! * 8!}$

$^{15}C_8 = \frac{15 * 14 * 13 * 12 * 11 * 10 * 9 * 8!}{7!8!}$

$^{15}C_8 = \frac{15 * 14 * 13 * 12 * 11 * 10 * 9}{7!}$

$^{15}C_8 = \frac{15 * 14 * 13 * 12 * 11 * 10 * 9}{7 * 6 *5 * 4 * 3 * 2 * 1}$

$^{15}C_8 = \frac{32432400}{5040}$

$^{15}C_8 = 6435$

Hence, the number of ways is 6435

The lengths of two sides of a triangle are shown below:

oksano4ka [1.4K]

Part A

$3x^2 -2x-1+9x+2x^2 -3=\boxed{5x^2 + 7x-4}$

Part B

$(5x^3 +4x^2 - x-3)-(5x^2 + 7x-4)=\boxed{5x^3 - x^2 - 8x+1}$

Part C

No, because although they provide examples for specific polynomials being closed under addition and subtraction, there is a loss of generality.
