Answer:

Table A

Step-by-step explanation:

looking at the two tables, we have the observations as follows;

For table B, if we divide x by y; we have a ratio of 2/3

This happens throughout the table

What this means is that x = 2/3 * y

But for table A, we notice a pattern for the first two lines

The pattern here is that x = 2y

But as we move to the next two rows, we notice this fails and thus, we fail to establish a pattern that works for all the rows;

Hence table B has a pattern for all its rows

Solve for x <br> 4(3+x)+x=x+4<br> TYYY

iris [78.8K]

$\sf\longmapsto 5x + 12 = x + 4$

$\sf\longmapsto 5x + 12 - 12 = x + 4 - 12$

$\sf\longmapsto 5x = x + 4 - 12$

$\sf\longmapsto 5x = 4 - 12$

$\sf\longmapsto 5x = - 8$

$\sf\longmapsto( 5x - x)$

$\sf\longmapsto 4x = - 8$

$\sf\longmapsto \frac{ - 8}{4} = - 2$

Find the 96th term of the arithmetic sequence 1, -12, -25, ...

goldenfox [79]

Answer:

The 96th term of the arithmetic sequence is -1234.

Step-by-step explanation:

first term (a)=1

second term (t2)=-12

common difference (d)= t2-a

d=-12-1

d=-13

96th term (t96)=?

We know that,

t96=a+(n-1)d

t96=1+(96-1)(-13)

t96=1+95(-13)

t96=1-1235

t96=-1234

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below

Dominik [7]

Answer:

Norma performed best on the aptitude test and should be offered the job.

Step-by-step explanation:

We are given that three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 74.7; this version has a mean of 61.7 and a standard deviation of 13. Norma got a score of 351; this version has a mean of 291 and a standard deviation of 25. Vincent got a score of 7.38; this version has a mean of 6.9 and a standard deviation of 0.4.

Now, to find which of the applicants should be offered the job, we have to find the z-score of each of the applicants, and the one who gets the highest z-score will get the job.

The z-score probability distribution for the normal distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = mean and $\sigma$ = standard deviation

Firstly, we will find the z-score for Tobias;

The z-score of 74.7 = $\frac{X-\mu}{\sigma}$

= $\frac{74.7-61.7}{13}$ = 1

Now, we will find the z-score for Norma;

The z-score of 351 = $\frac{X-\mu}{\sigma}$

= $\frac{351-291}{25}$ = 2.4

Now, we will find the z-score for Vincent;

The z-score of 7.38 = $\frac{X-\mu}{\sigma}$

= $\frac{7.38-6.9}{0.4}$ = 1.2

As we can clearly see that the z-score is highest for Norma which means that Norma performed best on the aptitude test and should be offered the job.
