The volume of a cube is 64 cubic meters. What is the surface area of the cube, in square meters?​
sergeinik [125]

Answer:

96 square meters

Step-by-step explanation:

Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.

We then find the area of one face which is 4 * 4 = 16 square meters.

We must then multiply this by the amount of sides on our cube which is 6.

16 * 6 = 96 square meters.

alukav5142 [94]

Answer:

Type II error occurred

Step-by-step explanation:

It is given that a new shampoo is being tested to determine whether the hair grows faster by using this shampoo.

It is known that hair grow at 0.5 inches per month at average.

The hypothesis are,

Null hypothesis, $H_0: \mu=0.5$

Alternate hypothesis, $H_1: \mu>0.5$

But it is known that :

Type $I$ error occurs when rejecting the null hypothesis when the null hypothesis is true actually.

Type $II$ error occurs \text{when we fail reject the null hypothesis} when the null hypothesis is actually false.

Now here since the null hypothesis is not been rejected, type  $II$ error had occurred.
