First, you add up the total number of students because we would base our percentage one this.
Total number of students = 1+4+5+10+20+10+5
Total number of students = 55
Now, let's count how many of them got a score of more than 70. For this, you would only count the students belonging to 70-under 80, 80-under 90 and 90-under 100.
Students who got more than 70 = 20+ 10 + 5 = 35
Therefore the percentage is equal to:
Percentage = 35/55 * 100 = 63.64%
Answer:
$ 1,131.56
Step-by-step explanation:
1,250x85%=1,062.50
1,062.50x6.5=69.06
1062.50+69.06=1,131.56
<em>P = a + b + c = 49 cm</em>
<em>a = b + 7 => b = a - 7</em>
<em>a = c - 5 => c = a + 5</em>
<em>_____________________</em>
<em>a + (a - 7) + (a + 5) = 49</em>
<em>3a = 49 + 7 - 5</em>
<em>3a = 51 </em>
<em>a = 17 cm</em>
<em>b = 17 - 7 = 10 cm</em>
<em>c = 17 + 5 = 22 cm</em>
<u>ANSWER</u>
B. 39,366
<u>EXPLANATION</u>
The y-values of the exponential function has the following pattern
:
:
Or
To find the average rate of change from x=9 to x=10, we simply find the slope of the secant line joining (9,f(9)) and (10,f(10))
This implies that,
Therefore the average rate of change from x=9 to x=10 is 39366.
The correct answer is B.
