Answer:
7
Step-by-step explanation:
1. Let
and
be the areas of 2 similar figures.
Similar figures have a scale factor k, (let k be >1, so k is the ratio of a distance in the larger figure to the corresponding distance in the smaller one)
The ratio of the area of the larger figure to the area of the smaller is
The ratio of the volume of the larger figure to the volume of the smaller is
2.
so k is 5/4
3.
in cubed
Answer:
D is correct.
Step-by-step explanation:
Given:
To find:
As we know,
This is parametric equation. Differentiate both function separately and substitute into formula.
and
Substitute into derivative
For double derivative differentiate w.r.t x
Hence, The value of
Answer:
The result can be shown in multiple forms.
(1,0),3.92699081

Answer:
k = 4
Step-by-step explanation:
The formula for binomial probability distribution is;
P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)
Where C(n, k) is the number of possible ways that n number of people choose k.
While p is probability of success
In this question, 20 children want to choose from 4 toys namely tricycle, blocks, a train set, and puzzles.
This means that from binomial probability distribution formula, n = 20 and k = 4.
