nikdorinn [45]

Answer:

0.0445937

Step-by-step explanation:

-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.

-Assuming normal distribution, the test statistic is calculated as:

z=\frac{Sample \ statistic-Null \ statistic}{\sigma/\sqrt{n}}\\\\=\frac{406-411}{\sqrt{225/26}}\\\\=-1.6997

-we then find the p-value of the test statistic from the z-tables:

P-value=0.0445937

Which is the directrix of a parabola with equation x^2=8y
stellarik [79]
According to the definition, is a parabola is in the standard form of (x-h)^2<span>=4p(y-k), then the directrix is y=k-p. In this case, the parabola function is x^2=8y, so h=0, p=8/4=2, k=0. Plug the values of h, p, k, into y=k-p, the directrix is y=-2.</span>

Three support beams for a bridge form a pair of complementary angles. Find the measure of each angle. (3x-20) and (7x+10)
stealth61 [152]

Answer:

3x-20=-6.6 degrees, 7x+10=1.4 degrees

Step-by-step explanation:

You solve each equate separately. So take the equation (3x-20) and solve for x first in that one. so you divide 3 by -20 to get -6.66 degrees for your first angle. Then you solve the other equation. (7x+10) divide 7 by 10 to get the angle measurement. Which would be 1.4 degrees.
