Answer 1

Answer:

137.67

Step-by-step explanation:

hello !

first, we find the midpoint of each interval in the score column (you can look for it by adding the two numbers and then dividing it by 2). then, we multiply the midpoint to the frequency:

1 - 7 is 4 = 4 * 17 = 68

8 - 10 is 9 = 9 * 15 = 135

11 - 15 is 13 = 13 * 13 = 169

16 - 20 is 18 = 18 * 6 = 108

23 - 35 is 29 = 29 * 6 = 174

36 - 50 is 43 = 43 * 4 = 172

now, we look for the mean, which we get by adding the sums and dividing the total with 6.

[tex]\frac{68+135+169+108+174+172}{6} = 137.6666667[/tex] or, when rounded to two decimal places, is equal to 137.67.

y = x^5 sin (2x) cos (4x)
find the derivative

Answers

y = x⁵ sin(2x ) cos(4x)

y' = d/dx (x⁵ sin (2x) × cos (4x) + x⁵ sin(2x) ). ×
d/dx (cos(4x) )

y' = 5x⁴ sin(2x) cos(4x)+2x⁵ cos(2x) cos(4x) -4x⁵ sin(2x) sin(4x)

The derivative of the equation will be y' = 5y/x + 2y cot (2x) - 4y tan (4x).

What is differential equation?

An equation containing derivatives of a variable with respect to some other variable quantity is called differential equations.

The derivatives might be of any order, some terms might contain product of derivatives and the variable itself, or with derivatives themselves.

They can also be for multiple variables.

y = x⁵ sin(2x ) cos(4x)

The differentiation;

y' = d/dx (x⁵ sin (2x) × cos (4x) + x⁵ sin(2x) ). × d/dx (cos(4x) )

y' = 5x⁴ sin(2x) cos(4x)+2x⁵ cos(2x) cos(4x) -4x⁵ sin(2x) sin(4x)

From the given equation;

y' = 5y/x + 2x⁵ cos(2x) cos(4x) - 4x⁵ sin(2x) sin(4x)

y' = 5y/x + 2y cot (2x) - 4y tan (4x)
