2 answers:

8 0

There are several information's already given in the question. Based on those information's, the answer can be easily deduced.
The equation given in the question is
x = 0.8x + 72
x - 0.8x = 72
0.2x = 72
x = 360
Now
Number of people that became
member of the site = (80/100) * 360
= 288 people
From the above deduction, it can concluded that the correct option among all the options that are given in the question is 288.

6(1) = 16<br> 6(n) = b(n − 1) + 1<br> Find the 2-term in the sequence.

Tresset [83]

Answer:

Step-by-step explanation:

Given

$b(1)=16\\ \\b(n)=b(n-1)+1$

Finding the second term of the sequence means to find $b(2).$ To find $b(2)$ substitute $n=2$ into the second expression:

$b(2)=b(2-1)+1\\ \\b(2)=b(1)+1\\ \\b(2)=16+1\\ \\b(2)=17$

What is the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81?

Marizza181 [45]

Answer: d. 1.3333

Step-by-step explanation:

We know that the standard error of a sampling distribution is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$

, where $\sigma$ = Population standard deviation.

n= Sample size.

AS per given , we have

$\sigma =12$

n=81

Then, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 will be :-

$S.E.=\dfrac{12}{\sqrt{81}}$

$=\dfrac{12}{\sqrt{9^2}}=\dfrac{12}{9}\\\\=\dfrac{4}{3}\\\\\approx1.3333$

Hence, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 is 1.3333.

Thus the correct answer is d. 1.3333 .

How to convert 750 in ^3 to yd^3

____ [38]

$\bf \stackrel{\textit{we know that }}{1yd=36in}\implies \stackrel{\textit{therefore}}{(1yd)^3=(36in)^3}\implies \stackrel{\textit{distributing the exponent}}{1^3yd^3=36^3in^3}\\\\\\1yd^3=46656in^3~\hspace{8em}therefore\\\\\\750 \underline{in^3} \cdot \cfrac{1yd^3}{46656 \underline{in^3}}\implies \cfrac{750 yd^3}{46656}\implies \cfrac{125 yd^3}{7776}~~~~\approx~~~~ 0.016075~yd^3$
