Answer:
Step-by-step explanation: Six less than a number is the same as one and four-tenths. The answer is this because a number represents z. When less is used in a word problem it almost always means subtract. Same as means equal to.
Answer:
P = 16x + 8
Step-by-step explanation:
Perimeter of a rectangle
= 2(L + W)
Given
L = 5x + 4 and
W = 3x
Therefore
Perimeter = 2(5x + 4 + 3x)
Rearrange the expression
P = 2(5x + 3x + 4)
P = 2(8x + 4)
Now expand the bracket
P = 2 x 8x + 2 x 4
P = 16x + 8
Answer:
True
Step-by-step explanation:
First, we need to recognize that
Now, we can try to solve
Multiply each side by 
As we end up with an answer that cannot be true, we know that there is no solution.
Another method to solve this would be graphing the function 
When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.
Answer: Even is not unusual.
Step-by-step explanation:
Given:
P = 0.10
n = 1200
x = 132
1. Sample of proportion ( ˆp ) = x/n
= 132/1200
= 0.11
2. Z = ˆp - p / √p ( 1 - p )/ n
= 0.11 - 0.10 / √0.10 ( 1 - 0.10 ) / 132
= 0.01 / 0.02611
= 0.3829
3. Probability
P ( ≥ 132 ) = P( Z > 1.50 ) = 1 - P( Z > 1.50 )
= 1 - 0.9332
= 0.0668
The probability is higher than (0.05). Which makes the event unusual, therefore there is no enough evidence which suggest that the number of Americans who are afraid to fly has increased.
