Dimas [21]

Answer:

The answer to your question is  c = \sqrt{2593}

Step-by-step explanation:

Data

right triangle

short leg = 17 cm

long leg = 48 cm

hypotenuse = ?

Process

-Use the Pythagorean theorem to find the answer

              c² = a² + b²

c = hypotenuse

a = short leg = 17 cm

b = long leg = 48 cm

- Substitution

             c² = 17² + 48²

-Simplification

             c² = 289 + 2304

             c² = 2593

-Result

             c = \sqrt{2593}

is it always,sometimes, or never true that a scatter plot that shows a positive association suggest that the relationship is pro
quester [9]
When a scatter plot shows a positive association means that there is a linear correlation with a positive slope between the two variables. This correlation can be weaker or stronger (depending on the value of the correlation).
If there is a linear correlation between the two variables, the relation is then a direct proportionality (with slope positive or negative).

Hence, it is always true that <span>a scatter plot that shows a positive association suggests that the relationship is proportional.</span>
