Answer:
c. has 12 hours of day and 12 hours of night for all locations
Step-by-step explanation:
The equinox is the time of the year marked by a nearly equal length of day and night. This word has a Latin root meaning which stands for equality, hence the word 'equinox'. It usually falls on March 21, and September 23 of every year. On these days the sun is above the equator.
The equinox which occurs around September happens in the Northern Hemisphere and is also known as the Fall or Autumnal equinox. Whereas, the equinox which occurs at the Southern Hemisphere is also known as the Spring or Vernal equinox. During an equinox, the tilt of the earth is perpendicular to the sun.
2x-2yd=y+xd
2x-y=xd+2yd
2x-y=d(x+2y)
(2x-y)/(x+2y)=d
So the answer is <span><span>d=<span><span>2x−y</span><span>x+2y</span></span></span></span>
Answer:
2(8+7)
Step-by-step explanation:
Answer:
1 1/4
Step-by-step explanation:
Rewriting our equation with parts separated
=1+24−14
Solving the fraction parts
24−14=14
Combining the whole and fraction parts
1+14=114
Answer:
8) B
9) D
*ASSUMING THE ALPHA-LEVELS FOR THESE PROBLEMS IS .05.*
Step-by-step explanation:
8) Left-tailed test means that the alternate hypothesis is x is less than a certain value. The p-value, on the calculator, is normalcdf(-999, -1.83) if it's left-tailed, which is .0336. In that case, we would reject the null hypothesis, because the alpha-level is above our p-value.
9) Two-tailed test means that the alternate hypothesis is x does not equal a certain value. The p-value for this, on the calculator, is normalcdf(1.95,999) times two, because we need both tails. In this case, we would fail to reject the null hypothesis, assuming our alpha-level is .05.
- normalcdf(1.95,999) = .0256*2 = .0512.
