For the given data value, find the standard score and the percentile. A data value 0.6 standard deviations above the mean.

TiliK225 [7]

Answer:

The z-score is $z = 0.6$

The percentile is $p(Z < 0.6) = 72.57\%$

Step-by-step explanation:

From the question we are told that

The data value is 0.6 standard deviations above the mean i.e $x = \mu + 0.6 \sigma$

Where $\mu$ is the population mean and $\sigma$ is the standard deviation

Generally the z-score is mathematically represented as

$z = \frac{x - \mu }{\sigma }$

=> $z = \frac{(\mu + 0.6\sigma ) - \mu }{\sigma }$

=> $z = 0.6$

The percentile is obtained from the z-table and the value is

$p(Z < 0.6) = 0.7257$

=> $p(Z < 0.6) = 72.57\%$

5x - 2y = 3

svlad2 [7]

Answer: Your answer is c

Step-by-step explanation: The first thing you can do is add the two equations together to cancel out x

5x-2y=3

-5x+4y=9

added them together will get us 2y=12, from here divide 2 and get y=6

Plug 6 into the first equation and solve for x.

5x-2(6)=3

5x-12=3, add 13 to the other side

5x=15, divide 5 and get the answer

x=3
