Answer:
152 / 370
Step-by-step explanation:
Total number of people
152+218 = 370
P( own a dog) = people said yes / total
= 152 / 370
They are 64, 128, and 256 i do believe
The statement that is not true about the given trigonometric graph is; Option A: The vertical phase shift of y = 3 sin(-5x - π/2) - 6 is; π/5
<h3>How to Interpret Trigonometric Graphs?</h3>
Let us analyze the options;
A) For the give equation;
y = 3 sin(-5x - π/2) - 6
From the general equation given we can say that;
A = 3
B = 5
C = -π/2
D = -6
Thus, phase shift = C/B = -(π/2)/5
Phase Shift = -π/10.
Thus, option A is not correct.
B) Period = 2π/B
Thus; Period = 2π/5
Formula for frequency from period is;
Frequency = 1/period
Thus, it is correct that Period and frequency vary indirectly
C) As B gets bigger, the period gets smaller and the frequency gets greater. Thus, this option is correct
D) This statement is correct.

X + y = 51
x - y =15
2x = 66
x = 33
33 + y = 51
y = 18
To calculate f(x) + g(x)
=3/5x + (-3x/2)
=3/5x - 3x/2
=2(3)/2(5x)-(5x)(3x)/(5x)(2)
=(6/10x-15x^2)/10x
=(15x^2-6)/-10x
Thus the answer is D
hope it helps!
