U have to count the models and find answer?I think;)
Answer:
A. (3.14)( 3) - (3.14)
Step-by-step explanation:
volume of the cone that can be filled with flavored ice = volume of cone - volume of the bubble gum
volume of cone = h
where r is the radius of the cone and h is its height.
volume of cone = x 3.14 x x 3
= 12.56 cube inches
volume of a sphere =
where r is the radius of the sphere.
radius =
=
radius = 0.25 inches
So that;
volume of the bubble gum = x 3.14 x
= 0.06542 cube inches
Thus,
volume of the cone that can be filled with flavored ice = 12.56 - 0.06542
= 12.49458
The volume of the cone that can be filled with flavored ice is 12.5 cube inches.
Answer:
$43,920.
Step-by-step explanation:
We have been given that the salaries of elementary school teachers in a particular country are normally distributed with a mean of $38,000 and a standard deviation of $4,000.
We will use the normal distribution table to solve our given problem. From normal distribution table, we need to find the z-score corresponding to the top 7% or z-score corresponding to probability 93% (0.93).
From normal distribution table, we get our required z-score as 1.48.
Now, we will use z-score formula to solve for sample score as:
Therefore, the cutoff salary for teachers in the top 7% is $43,920.
