I hope this helps you

0,2x+0,2+0,5x= -0,3x+1,2

0,7x+0,3x=1,2-0,2

x=1

Answer:

The value of the x is 1 .

Step-by-step explanation:

As given the expression in the question.

0.2(x + 1) + 0.5x = –0.3(x – 4)

Now first open the bracket

0.2x + 0.2 + 0.5x = –0.3x – 4 × -0.3

0.2x + 0.2 + 0.5x = –0.3x + 1.2

0.2x + 0.5x + 0.3x = 1.2 - 0.2

1.0x = 1.0

$x = \frac{1.0}{1.0}$

x = 1

Therefore the value of the x is 1 .

Round your answer to the nearest hundredth

Anton [14]

Answer:

9.49

Step-by-step explanation:

Using the Pythagorean Theorem, we know a²+b²=c².

So 3²+9²=(BA)²

9+81=(BA)²

90=(BA)²

From this, we know BA=√90

BA=9.486

Rounding to the nearest hundredth, this is 9.49

How many different simple random sampmes of size 5 can be obtained from a pppulation whose size is 43?

Nesterboy [21]

Answer:

Number of random samples = 962598

Step-by-step explanation:

A random sample represents the responses for a certain survey of a part of the population.

A sample size is the part of the population being surveyed.

For a population $N$ the number of different random samples that can be chosen for a sample size $x$ can be calculated as = $NCx$

This can be calculated as :

$NCx=\frac{N!}{x!(N-x)!}$

Given:

Population size = 43

Sample size = 5

Number of random samples = $43C5$

⇒ $\frac{43!}{5!(43-5)!}$

⇒ $\frac{43!}{5!(38)!}$

⇒ $\frac{43\times42\times41\times40\times39}{5\times4\times3\times2\times1}$ [Canceling out the common terms]

⇒ $962598$ (Answer)
