1. The answer would be about 20.72, or 20.7142 if you don’t want the rounded version
2. The answer is -12.8
The parabola's vertex would not be on the x-axis or y-axis and there would be no x-intercepts.
Answer:
Tn=a+(n-1)d
a=a1
Tn=a1+(n+1)d
I would appreciate if my answer is chosen as a brainliest answer
Answer:
The mean = 17.54
Step-by-step explanation:
Form a table as below;
<u>Interval Frequency{f} Midpoint of frequency{x} fx </u>
1-7 19 4 76
8-10 14 9 126
11-15 15 13 195
16-20 20 18 360
21-35 10 28 280
36-50 13 43 559
Sum 91 1596
The mean of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency
The mean= 1596 / 91
The mean = 17.54
Answer: 52
Step-by-step explanation:
a^2+b^2=c^2
x is the hypotenuse (c). You can find the hypotenuse by finding the opposite of the right angle
48^2+20^2=2304+400=2704
√2704=52
x=52
