Answer:

two sample z-test for population proportions

Step-by-step explanation:

The hypothesis test that would best fit this scenario would be a two sample z-test for population proportions. This is because you have a single population which is divided into two categories, those who do exercise and those who don't. Since you have two options and the outcome of the test needs to be either true or false then this hypothesis test would provide the best results for this scenario by comparing the data and then providing a simple true or false output for the question provided.

Determine the quadrant when the terminal side of the angle lies according to the following conditions: cos (t) < 0, csc (t) &
Bess [88]

Answer:

The angle is in the second quadrant.

Step-by-step explanation:

The cosecant of an angle is the same as the reciprocal of the sine of that angle. In other words, as long as \sin (t) \ne 0,

\displaystyle \csc t = \frac{1}{\sin t}.

Therefore, \csc(t) > 0 is equivalent to \sin (t) > 0.

Consider a unit circle centered at the origin. If the terminal side of angle t intersects the unit circle at point (x,\, y), then

  • \cos (t) = x, and
  • \sin(t) = y.

For angle t,

  • x = \cos(t) < 0, meaning that the intersection is to the left of the y-axis.
  • y = \sin(t) > 0, meaning that the intersection is above the x-axis.

In other words, this intersection is above and to the left of the origin. That corresponds to second quadrant of the cartesian plane.

NARA [144]
X/3 +10=15
         -10   -10
x/3       =5

so the x will be 15 because if you multiply 3x5 = 15

Is a tray with a circumference of 32 inches is big enough to
yKpoI14uk [10]

Answer:

Yes

Step-by-step explanation:

Circumference formula is C=2 pi r, if you divide the pizza by 2 to get the radius,5, then input it into the formula to get 31.41592654, and since this number is smaller than 32 it will fit. If 10 is the radius it will not fit.

Round 2769.44 to the nearest tenths place
vlada-n [284]
It would be 2769.44 still since it would technically be 2769.440 if you were rounding to the TENTHS place. The Zero(0) doesn't change anything so the answer is

2769.44
