The correct answer is
0.4
Answer:
0.01 is the difference between the 2006 study and the sampe which is negligible hence why we can't say the proportion of Americans who are afraid to fly has increased.
Step-by-step explanation:
In 2006, the proportion of Americans afraid to fly is 0.10.
Then a random sample of 1300 Americans results in 143 indication that they are afraid to fly.
The proportion for this random sample is:
0.11 is the proportion of Americans afraid to fly based on the random sample.
This proportion is not necessarily evidence that the proportion of Americans who are afraid to fly has increased because the difference between the proportion of the sample and the 2006 study is negligible.
The difference is:
and 0.01 is negligible.
Identify the SLOPE (m) and the Y-INTERCEPT (b).
To find the y-intercept, find the point where the line crosses the y-axis.
To find the slope, pick two points on the line that are easy to read.
Then see how many units up or down and how many units right or left you need to go from the first point to the second point. Divide the up or down (the rise) by the right or left (the run). That is the slope.
The equation is
y = mx + b,
where m = slope and b = y-intercept.
Answer:
one is 2 inches bigger that the other.
Step-by-step explanation:
becuase if one of the pizza is 20in ans the other is 22 the 20 on is only 2in away frof the XXL pizza .
Let's use the variable 'n' to represent the cost of a notebook and 'p' the cost of a pen.
If Kennel wants an equal number of notebooks and pens, we can create a group of one notebook and one pen, and the resulting cost will be 'n + p'
Then, to find the number of these groups Kennel can buy, we just need to divide the amount of money ($40) by the cost of the group of one notebook and one pen:
If the result is not a whole number, we need to round it down, since we can't spend more money than the budget of $40.
