"seven" means ' 7 '
"two" means ' 2 '
"the quantity seven plus two" means ' (7 + 2) '
"one hundred times the quantity ..." means ' <em>100 (7 + 2)</em> '
That's the expression.
One of the rules for handling these things is that you should always
take care of anything inside parentheses first. So do that.
(7 + 2) = 9
Now you can can write the expression like this: ' 100 (9) ' .
That's just <em>900 .

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.
<h3>What is the margin of error?</h3>
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,

Hence, the Margin of error in this survey is 1%.

Answer:
A) 0.2g
Step-by-step explanation:

Answer: y = -1/3x + 10
Step-by-step explanation:
To make it perpendicular change the reciprocals
So instead of 3x it'll be -1/3x and so it passes through the given points
plug the points
8 = -1/3(6) + b
8 = -2 + b
add 2 to both sides
10 = b
so the equation of a line thats perpendicular to y=-3x-10 and passes through
points (6,8) is
y = -1/3x + 10
