156787 can go into 4 how many times???????

√(2x+1)<br> Evaluate the integral<br> 2<br> (2x + 1) In (2x + 1)<br> dx.

Crank

Substitute $y=\ln(2x+1)$ and $dy=\frac2{2x+1}\,dx$ , so that

$\displaystyle \int \frac2{(2x+1) \ln(2x+1)} \, dx = \int \frac{dy}y = \ln|y| + C = \boxed{\ln|\ln(2x+1)| + C}$

What number is 15% of 80?<br> use percent proportions

vova2212 [387]

!5% is equivalent to 15 parts over the whole 100 part. It is written in proportions as 15/100.

Similarly, you need to find how many parts in 80 are equivalent to 15%or 15/100. So, just equate both equation with x as an unknown.

x/80 = 15/100
x = (15/100)*80
x = 12

Thus, the 15% of 80 is 12.

In-s [12.5K]

The central tendency researcher use to describe these data is "mode".

The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data. The mean, or average of a set, and the median, or middle value in a set, are two more common measurements of central tendency.

Calculation of mode is done by-

The number that appears the most frequently in a piece of data is its mode.
Put the numbers in ascending order by least to greatest, then count the occurrences of each number to quickly determine the mode.
The most frequent number is the mode.
Simply counting how many times each number appears in the data set can help you identify the mode, which is the number that appears the most frequently in the data set.
The figure with the largest total is the mode.
Example: Since it happens most frequently, the mode for the data set [5, 7, 8, 2, 1, 5, 6, 7, 5] is 5.

Which of the following rules could represent the function shown in the table?

kvasek [131]

ANSWER

The rule is given by the relation,

$y = 2x + 1$

EXPLANATION

We need to check and see if there is a constant difference between the y-values.

$1 - - 1 = 2 = 3 - 1$

We can see that, there is a constant difference of 2.

This means that the table represents a linear relationship.

Let the rule be of the form,
$y = mx + c$

Then the points in the table should satisfy the above rule.

So let us plug in

$(0,1)$

This implies that,

$1 =m (0) + c$

$1 = 0 + c$

$c = 1$

Our rule now becomes,

$y = mx + 1 - - (1)$

We again plug in another point say, (-1,-1) in to equation (1) to get,

$- 1 = m( - 1) + 1$

we solve for m now to obtain,

$- m=-1-1$

$- m = - 2$

$m = 2$
We now substitute back in to equation (1) to get

$y = 2x + 1$
