You subtract 13 from both sides of the = sign so ×=12
A Point-Slope equation of a straight line has this form: y - y1 = m(x-x1)
We can recognize any points of the graph.
(0,80000) ; (10,50000)
Given:
<span>y -50,000 =______(x -10)
We need to find the slope.
Slope = Change in y / Change in x = 80,000 - 50,000 / 0 - 10 = 30,000 / -10 = -3,000
The slope is equal to -3000. Choice A.
</span><span>y -50,000 = -3,000(x -10)</span>
So the fisrt thing we need to calculate is that 9 times out of 10 is 90% which will be the confidence interval.
<span>Margin of error is 6% = .06 </span>
<span>Confidence interval is 80 +/- .06 = .74 to .86. or 74% to 86$ </span>
<span>In 9 times out of 10 the confidence interval for similar samples of seniors will contain the </span><span>true mean of the population of senior scores. </span>
Its easy all you do is add the time given or subtract it
Answer:
5 1/10 meters
Step-by-step explanation:
18 4/5 can be changed to 18 8/10 so
18 8/10 - 13 7/10 = 5 1/10 meters
