Which is the graph of y = _0.4x? A. B. C. D.

1 answer:

8 0

Y = -0.4x

1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °

With all that information you can identify the graph, given that you didn't include the options.

Answer:

q - p

Step-by-step explanation:

For complementary angles B and C, ...

cos(C) = sin(B) = p

sin(C) = cos(B) = q

Then the difference is ...

sin(C) -cos(C) = q - p

A random sample of 169 observations is to be drawn from a population with a mean of 80 and a standard deviation of 39. find the

Drupady [299]

Mu=80, sigma=39, X=85
Z=(X-mu)/sigma = 5/39=0.128=0.13
P(X<=85)= 0.5517 (from Z-table)
so, P(X>85)=1-0.5517=0.4483 approx. thats 44.8% probability.
