Kindly note that the data supplied is not up to 20. Hence, the answer will be based on the number of data given.
Answer:
Step-by-step explanation:
Given the following data:
BMI of 20 females :
17.7. 33.5. 26.6 24.7
28.8. 23.8. 18.3. 22.1
19.2. 22.6. 22.7. 38.9
27.3. 44.9. 32.2. 23.9
Lower class limit (LCL) = 15.0
Class width = 6.0
Class_interval_____frequency
15.0 - 20.9 _________3
21.0 - 26.9 _________7
27.0 - 32.9 _________3
33.0 - 38.9 _________2
39.0 - 44.9 _________1
We are given function f(x) = 25x^2 -2.
g(x) is a vertical stretch of f(x) by a factor of 2.
We know, the transformation rule
y= k f(x), vertical stretch by a factor k. For k>0.
Because function f(x) is being vertical stretched by a factor of 2. So, we need to multiply f(x) function by 2.
Therefore, g(x) = 2 f(x) = 2*(25x^2-2).
Therefore, g(x) = 2*(25x^2-2) or g(x) = 50x^2-4.
Answer:
Option b (1/2,1/3)
Step-by-step explanation:
we have
2x-3y=0 ------> equation A
4x+6y=4 -----> equation B
Solve the system by elimination
Multiply equation A by 2 both sides
2(2x-3y)=2(0)
4x-6y=0 ------> equation C
Adds eqution B and equation C
4x+6y=4
4x-6y=0
-------------
4x+4x=4+0
8x=4
x=1/2
Find the value of y
2x-3y=0
2(1/2)-3y=0
1-3y=0
3y=1
y=1/3
the solution is the point (1/2,1/3)
Answer:
g(x) = 5 – x
