Answer:
False
Step-by-step explanation:
In chemistry, the acidity of a solution is measured using the pH scale 0-14. A solution that's pH 3 is 10 times more acidic than a solution that's pH 4. The lower the pH the more acidic something is. The higher the pH the more basic something is. Water is generally around pH 7 (calculated using logarithms)
Also, in seismology. <span>Vibrations are picked up and plotted on a seismograph. The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10.
</span><span>
</span><span>So an earthquake thats a 5 on the Ricter scale is 10 times stronger/bigger than one that's a 3. (Logarithms)

Biologists that calculate population growth, whether animal, human or microorganism. When organisms create more organisms in a population they grow exponentially. (exponential functions)
Also, a lot of financial things like compound interest on a saving account or loan. (exponential function)

The Correct option is ~ B
Let's find the slope (m) using points (2 , 1) and (0 , -3)
hence, slope = 2
now, by Observing the given graph we can infer that the given line cuts the y - axis at point (0 , -3), so value of y - intercept (c) = - 3
[ y - coordinate of a point when x - coordinate is equal to 0 is the value of y - intercept of a line ]
And, we know the general equation of line in slope - intercept form is ~
now, let's plug the value of slope (m) and y - intercept (c) in the general equation to find the equation of line in slope intercept form ~
Answer:
Mean of a grouped data is
Sum of F x/ sum of frequency F
Sum of F = 5 + 15 + 13 + 10 + 7 = 50
to find x find the average of the two classes
That's
0 + 10/2 = 10/2 = 5
10+20/2 = 15
20 + 30 / 2 = 25
30+40 /2 = 35
40+ 50 / 2 = 45
Therefore sum of Fx = 5(5) + 15(15) + 13(25) + 10(35) + 7(45)
= 1240
Therefore
Mean = 1240/50
= 24.8cm
