2 answers:

8 0

X3 - 10x2 + 24x
= x(x2 - 10x + 24) 
= x(x2 - 4x - 6x + 24) 
= x[ x(x - 4) - 6(x - 4) ] 
= x(x - 6)(x - 4)

How do I get the answer

Ronch [10]

Answer:

Step-by-step explanation:

$- |3a + \sqrt{b} |$

By putting the values of a = -4 , b = 9,

$= - |3 \times ( -4) + \sqrt{9} |$

$= - | - 12 + 3|$

$= - | - 9|$

= -(9)

= -9 (Ans)

The Director of Admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall sem

VMariaS [17]

Answer:

Variance = 24900

Standard Deviation = 157.7973

Step-by-step explanation:

We are given the following in the question:

Number of admissions: 1000 1200 1500

Admissions Probability: 0.6 0.3 0.1

Formula:

$E(x) = \displaystyle\sum x_iP(x_i)\\E(x) = 1000(0.6) + 1200(0.3) + 1500(0.1)\\E(x) = 1110\\E(x^2) = \displaystyle\sum x_i^2P(x_i)\\E(x^2) = (1000)^2(0.6) + (1200)^2(0.3) + (1500)^2(0.1)\\E(x^2) = 1257000$

Variance =

$\sigma^2 = E(x^2) - (E(x))^2\\\sigma^2 = 1257000 -(1110)^2\\\sigma^2 =24900$

Thus, the variance is 24900.

Standard Deviation =

$\sigma = \sqrt{\sigma^2} = \sqrt{24900} = 157.7973$

Thus, the standard deviation is 157.7973

Step problems please

notka56 [123]

Answer:

Step-by-step explanation:

7. Let the price of book be x

:- 8x + 17 = 129

8x = 129 - 17

8x = 112

x = 112/8

x = $14

Each book cost $14

8. Let the number of hours be x

9x + 15 = 87

9x = 87 - 15

9x = 72

x = 72/9

x = 8hrs

He paid for 8hours

9. Let the numbers be x, x +2, x +4,

So. x + x + 2 + x + 4 = 168

3x + 6 = 168

3x = 168 - 6

3x = 162

x = 162/3

x = 54

The smallest number is 54

10. Let the number of books be x

So, x/2 + 6 = 18

x/2 = 18 - 6

x/2 = 12

x = 12 ×2

x = 24

So she has 24 book's before
