Answer:
Step-by-step explanation:
Given
Shapes: Cube and Cone
Required
Determine the volume
First we calculate the volume of the cube
Where
l = side length = 5.1
Next, calculate the volume of the cone using:
Where
h = 5.1
So, we have:
The volume of the figure is:
Answer:
a) For this case we can see the distribution in the figure attached is a bell shaped graph and symmetrical around 71
b)
We can see the value of 76 labeled in the second picture attached
c)
And using the z score we have this using the normal standard table or excel:
d)
We can say that about 154 and 155 students scored higher than Angelica
Step-by-step explanation:
We know that X represent the random variable scores of knowledge test and is given by:
Part a
For this case we can see the distribution in the figure attached is a bell shaped graph and symmetrical around 71
Part b
For this case the z score is given by:
And replacing we got:
We can see the value of 76 labeled in the second picture attached
Part c
We want this probability:
And using the z score we have this using the normal standard table or excel:
Part d
For this case we can find the number desired like this:
We can say that about 154 and 155 students scored higher than Angelica
