<h3>Answer:  53%</h3>

===========================================================

Explanation:

The question asks "What percent of females participate in extracurricular activities?" This means we only focus on the second column. There are 36 women, and of this total, 19 are in extracurricular activities.

Dividing the two values leads to approximately 19/36 = 0.52777 which rounds to 0.53

Then we move the decimal to the right two spots to get 53%

Roughly 53% of the female students participate in extracurricular activities.

Help pls ! This is trigonometric function
storchak [24]

Answer:

Amplitude: 4

Period: π

midline: y = 1

Step-by-step explanation:

r(x) = -4 sin(2x) + 1

r(x) = a sin(bx + c) + d where |a| is the amplitude and |b| for the period

a = -4         |a| = 4 :   Amplitude = <u>4</u>

b = 2          |b| = 2     period of sin(x) = 2π

                                period of sin(bx + c) = 2π/|b| = 2π/2 = <u>π</u>

range of sin(2x) ... -1 ≤ sin(2x) ≤ 1

range of -4 sin(2x) + 1: -4+1 ≤ -4 sin(2x) + 1 ≤ 4+1    

-3 ≤ -4 sin(2x) + 1 ≤ 5

midline: y = (-3 + 5) / 2 = 1        y = 1

If m2 = 7x + 7, m3 = 4y, and m4 = 112, find the values of x and y
maks197457 [2]
M2 x 2 = m4
soo m2 now becomes m4 = 14x + 14
112 = 14x + 14
subtract 14 from both sides
98 = 14x
divide by 14 on both sides 
7 = x

to find Y, 12 is the lowest number you can make 3 & 4
so multiply m3 by 4 and m4 by 3
so instead of m3 = 4y and m4 = 112 it now becomes
m12 =16y and m12 = 336
16Y = 336
divide both sides by 16 
Y = 21
