It takes 3 pumps 16 hours to empty a tank
Meaning it takes 48 hours for one pump by its self
So if there are 4 pumps
48/4 it would take them 12 hours
They would need to work 12 hours to do it in 1 day

Find the slope of the line that passes through (100, 56) and (28,94)

Rus_ich [418]

Answer:

-19/36

Step-by-step explanation:

We can find the slope using

m = ( y2-y1)/(x2-x1)

m = ( 94-56)/( 28 -100)

= 38 / -72

= -19/36

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

$p(Z < 0.6) = 0.7257$

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