<span>(4.4*10^6) = 4400000
and
</span><span>(3.9*10^4) = 39000
</span>
The exponents on top of the 10 tells you how many decimals you're supposed to move it to. If it's a negative number, you'll need to move the same amount of decimals, but to the left side instead.
for example: 4.3*10^-3 =0.0043

in this case, however, you should refer to the Laws of Exponents.
<span>(4.4*10^6)*(3.9*10^4)
= 4.4 * 3.9 * 10^6 * 10^4
= 17.16 * 10^(6+4) <-- Law of Exponents say that when you multiply exponents with the same base, you add the exponents together.
= 17.16 * 10^10</span>

Resolve this equation

mel-nik [20]

The expression above can be resolved to become; (5a + b)³

According to the question:

We are required to determine resolve the expression as given in the question.

To resolve the expression given;

We are required to multiply the polynomials as follows;

(5a + b) (25a² + 10ab² + b²)

= 125a³ + 50a²b² + 5ab² + 25a²b + 10ab³ + b³

However; the expression above can be factorised to become;

<em>(5a + b)³</em>

Upon expansion; (5a + b)³ yields the expression gotten earlier;

<em>125a³ + 50a²b² + 5ab² + 25a²b + 10ab³ + b³</em>

Use Random number generator and simulate 1000 long columns, for each of the three cases. Example: for the Car type 1, use Number

sertanlavr [38]

Answer:

Step-by-step explanation:

The question is incomplete since they do not give information about the Car type 3.

We will do it in a generic way, we will say that the Car type 3 has a mean of M and a standard deviation SD.

We would be:

P (CT3 <550) = P [z <(550 - X) / SD]

Now if we give it values, for example that X = 600 and SD = 120

It would remain:

P (CT3 <550) = P [z <(550 - 600) / 120]

P (CT3 <550) = P [z <-0.42]

We look for this value in the normal distribution table (attached) and it shows us that the probability is approximately 0.3372, that is, 33.72%

What you need to do is replace the X and SD values of theCar type 3 in the equation above how I just did and you will get the result.

Part of the population of 7,500 elk at a wildlife preserve is infected with a parasite. A random sample of 50 elk shows that 3 o

vagabundo [1.1K]

When the sample is given, the number of elk are likely to be infected is to be considered as the 450.

<h3>Calculation of the number of elk:</h3>

Since the population is 7,500.

The random sample is 50.

So here be like

$7500$ ÷ $50$ × $3$

= 450

hence, When the sample is given, the number of elk are likely to be infected is to be considered as the 450.
