We have been given an equation 
. We are asked to solve the equation for t.
First of all, we will divide both sides of equation by a.
Now we will take natural log on both sides.
Using natural log property 
, we will get:
We know that 
, so we will get:
Now we will divide both sides by c as:
Therefore, our solution would be .
<h2>Answer</h2>
0.43
<h2>Explanation</h2>
Remember that 
Since the problem is telling us "Among tenth graders", we must focus on the 10th graders row only. From the row, we can infer that the frequency is the number of 10th graders who prefer going to sporting events, so 
. Now, the sum of all frequencies will be the sum of all the 10th graders, so 
. Let's replace the values:
And rounded to the nearest hundredth:
Y = 3x - 7...slope here is 3 and y int is -7
3x + 9y = 9
9y = -3x + 9
y = -1/3x + 1....slope here is -1/3 and y int is 1
the slopes 3 and -1/3 are negative reciprocals of each other...therefore, ur lines are perpendicular
Answer:
0.1/4-3/20=1/40-6/40=-1/8 200% of this is -1/4
Step-by-step explanation:
5c+3b=29.99
3c+7b=32.71
15c+9b=89.97
15c+35b=163.55
26b=73.58
b=2.83
c=4.30
