Answer:
A. = 3.053
B. = 1.85
C. =-1.85
D. since the z sore is less than -2, the highest weight is significantly low
Step-by-step explanation:
a) Difference between weights
= 5.31 - 2.527
= 3.053
b) Number of standard deviations = = 3.053÷1.655
= 1.85
c) the z score = \frac{\bar{X}-5.26}{s}
= (2.527 - 5.31 )÷1.655
= −3.053 ÷ 1.655
=-1.85
d) since the z sore is less than -2, the highest weight is significantly low
Answer:
Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
Step-by-step explanation:
Let X=set of all odd numbers
that is
Let Y=set of all even numbers
that is
Verify that 2(n+1) represents an even number where n is an odd number:
Put n=1 in 2(n+1) we get
2(1+1)=2(2)=4
Put n=3 in 2(n+1) we get
2(3+1)=2(4)=8
Put n=5 in 2(n+1) we get
2(5+1)=2(6)=12
and so on.
From above results we get 2(n+1) represents an even number and is belongs to the set Y when n is an odd number.
Therefore Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
Answer:
dy/dx = 18x – 6
Step-by-step explanation:
y = (3x – 1)²
Take derivative using power rule and chain rule:
dy/dx = 2 (3x – 1) × 3
dy/dx = 6 (3x – 1)
dy/dx = 18x – 6
You can check this answer by simplifying y before taking the derivative.
y = 9x² – 6x + 1
dy/dx = 18x – 6
