4.5 is the raidius
pls mark me the brainliest
Cho hai tập hợp A = {0,1,4,7,8,9}, B = {1,2,3,4,6,7,8}.Tập hợp B\A bằng:
SVEN [57.7K]
Đáp án
A. {2,3,6}
Lời giải:
B\A là tập hợp các phần tử B có mà A không có. => B\A = {2,3,6}
The ratio is 2 : 9
Step-by-step explanation:
Given:
The number of sports store = 4
The number of clothing store = 9
The number of jewellery stores = 5
To Find :
The ratio of number of sports stores to the total number of stores
Solution:
The ratio of number of sports stores to the total number of stores
= 
The total number of stores = number of sports store + number of clothing store + number of jewellery store
The total number of stores = 4 + 9 + 5
The total number of stores = 18
Now the ratio is
=
or 4 : 8
The ratio after reduction is
=
or 2 : 9 or 2 to 9
Option B: 5 is the value of f(3)
Explanation:
The equation of the piecewise function is given by

We need to find the value of 
The value of the function f can be determined when
by identifying in which interval does the value of
lie in the piecewise function.
Thus,
lies in the interval
, the function f is given by

Substituting
in the function
, we get,


Thus, the value of
is 5.
Therefore, Option B is the correct answer.
Answer:
The answer is 120
Step-by-step explanation:
