Rini used a stick to draw a right triangle in the ground. The hypotenuse of her triangle is 24 inches and one of the legs is 12

Mademuasel [1]

Use the pythagorean theorem A² + B² = C²

A and B are legs and C is the hypotenuse

so- A² + 12² = 24² A² + 144 = 576
-144 -144

A² = 432 then you have to take the square root
of each side

so- A = √432 or aprox. 20.78

The mean is 163.4 cm and the standard deviation is 6.7 cm. Convert the mean and standard deviation to inches

disa [49]

Answer:

The mean is 64.33 inches and standard deviation is 2.64 inches.

Step-by-step explanation:

Given:

Mean = 163.4 cm

Standard deviation=6.7 cm

Solution:

As we know $1\ cm=\frac{1}{2.54}\ in$

So for mean, $163.4\ cm= \frac{163.4}{2.54} =64.33 \ in$

For standard deviation, $6.7 cm= \frac{6.7}{2.54} =2.637\approx 2.64 \ in$
