Answer:

4 19/27

Step-by-step explanation:

x = 2 1/3 - 2

= 1/3

x³ + 6x² + 12x =

= (1/3)³ + 6(1/3)² + 12(1/3)

= 1/27 + 6×1/9 + 12×1/3

= 1/27 + ⁹⁾2/3 + ²⁷⁾4

= (1 + 18 + 108)/27

= 127/27

= 4 19/27

Find aquadratic polynomialthe sum and product of whose zeroes are -3 and 2

Katen [24]

Answer:

$x^2+3x+2$

Step-by-step explanation:

Hello, if a and b are two zeroes of a polynomial P(x), we can write

$P(x)=(x-a)(x-b)=x^2-(a+b)x+ab$

We know that the sum is -3 and the product is 2, so

$x^2+3x+2$ follows this pattern.

A student repeatedly measures the mass of an object using a mechanical balance and gets the following values: 560 g, 562 g, 556

MrRissso [65]

Answer: 2.76 g

Step-by-step explanation:

The formula to find the standard deviation:-

$\sigma=\sqrt{\dfrac{\sum(x_i-\overline{x})^2}{n}}$

The given data values : 560 g, 562 g, 556 g, 558 g, 560 g, 556 g, 559 g, 561 g, 565 g, 563 g.

Then, $\overline{x}=\dfrac{\sum_{i=1}^{10} x_i}{n}\\\\\Rightarrow\ \overline{x}=\dfrac{560+562+556+558+560+556+559+561+565+563}{10}\\\\\Rightarrow\ \overline{x}=\dfrac{5600}{10}=560$

Now, $\sum_{i=1}^{10}(x_i-\overline{x})^2=0^2+2^2+(-4)^2+(-2)^2+0^2+(-4)^2+(-1)^2+1^2+5^2+3^2\\\\\Rightarrow\ \sum_{i=1}^{10}(x_i-\overline{x})^2=76$

Then, $\sigma=\sqrt{\dfrac{76}{10}}=\sqrt{7.6}=2.76$

Hence, the standard deviation of his measurements = 2.76 g
