Answer: 74
Step-by-step explanation:
Substitute x=6 into the expression
(x+4) . 2^3 -6
Add the numbers
(6+4) . 2^3- 6
10 x 2^3 -6
Evaluate the power
10 x 2^3 -6
10 x 8-6
Multiply the numbers
10 x 8-6
80-6
Subtract the numbers
80-6
74
Answer:
A. H0: μ = 6 vs. Ha: μ > 6
H0 : µ = 6 vs. Ha : µ > 6
Step-by-step explanation:
Null hypotheses state that there is no difference between a parameter and a specific value.
Alternative hypotheses states a specific difference between a parameter and a specific value.
Null hypotheses is represented as H0
Alternative hypotheses is represented as Ha.
From the question,
The claim is this "Is the mean height for all adult American males between the ages of 18 and 21 now over 6 feet?" The claimed statement represent the Alternative hypotheses.
So, the alternative hypotheses is:
Ha: μ > 6
While the null hypotheses is:
H0: μ = 6
Answer:
3
Step-by-step explanation:
A ( 2, 2 )
( x1, y1 ) = ( 2, 2 )
Here,
x1 = y1 = 2
B ( - 2, - 2 )
( x2, y2 ) = ( - 2, - 2 )
Here,
x2 = y2 = - 2
Distance formula : -
d = √ ( x2 - x1 )² + ( y2 - y1 )²
AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²
= √ ( - 2 )² + ( - 2 )²
= √ 4 + 4
AB = √8
The value of √8 is 2.828.
Roundoff to nearest 10 is 3.
