Answer:

Let x represents the number.

Given the statement: "Three less than the product of a number and two, increased by five".

"Product" means multiply

"Product of a number and two" translated to $2x$

"Three less than the product of a number and two" translated to 2x - 3

Increased by 5 means +5

then;

the given statement becomes;

$(2x-3)+5$

Therefore, the expression that represents "three less than the product of a number and two, increased by five" is $(2x-3)+5$

What is the radius of convergence of the maclaurin series (2x)/(1+x^2)?

kramer

To solve this problem you must apply the proccedure shown below:
1. You have to find the radius <span>of convergence of the following Maclaurin series:
</span> $(2x)/(1+ x^{2} )
$
2. Let's take the denominator and find the roots:
$1+ x^{2} =0$
$x^{2} =-1 \\ x= \sqrt{-1} \\ x1=i \\ x2=-i$
3. The roots are $x1=i \\ x2=-i$ and the distance from the origin is $1$ .
Therefore, the answer is: $1$

As an introduction to probability, a student asked to roll a fair, six sided number cube seven times the results of those seven

Using it's concept, the standard deviation of the data is of 3.742.

<h3>What are the mean and the standard deviation of a data-set?</h3>

The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.

The standard deviation of a data-set is given by the square root of the <u>sum of the differences squared between each observation and the mean, divided by the number of values</u>.

For this data-set, the mean is:

M = (1 + 4 + 4 + 4 + 4 + 6 + 5)/7 = 4.

Hence the standard deviation is:

$S = \sqrt{\frac{(1 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (4 - 4)^2 + (6 - 4)^2 + (5 - 4)^2}{7}} = 3.742$

kifflom [539]

Answer:

multicellular organisms = 14

Step-by-step explanation:

given data

multicellular organism = 625 sq feet

total = 8750 sq feet

solution

we will gethere

as we know that 1 multicellular organism = 625 sq feet

we get here multicellular organisms that is

multicellular organisms = ( 8750 ×1 ) ÷ 625

multicellular organisms = 14
