Sphinxa [80]

Answer:

10.29 u

Step-by-step explanation:

Given :-

Two points (7,4) and (-2,9) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

$:\implies$ D = √{(x2-x1)² + (y2-y1)²}

$:\implies$ D =√[ (7+2)² +(9-4)²]

$:\implies$ D =√[ 9² +5²]

$:\implies$ D =√[ 81 +25]

$:\implies$ D = 10.29

<h3>Hence the distance between the two points is 10.29 units .</h3>

Answer:

119.2

Step-by-step explanation:

Given the following :

Mean (m) = 100 years

Standard deviation (sd) = 15 years

closest to the age of a Galápagos Islands giant tortoise at the 90th percentile of the

distribution?

Obtain the Zscore for 90th percentile (0.90) on the z table = 1.28

Zscore = (X - mean) / standard deviation

1.28 = (X - 100) / 15

1.28 × 15 = X - 100

19.2 = X - 100

19.2 + 100 = X

X = 119.2
