Check the picture below.
now, based on the provided information, we know the hexagon and triangle are regular polygons, <u>equal sides and equal angles</u>, we also know the angle in pink there of E and G are twins inside that irregular trapezoid, and you can see the exterior angles labeled there of 220° and 136°.
now, the trapezoid has twin angles at E and G, that means that the sides of DE and JG are equal and that also means that the other two angles inside that trapezoid are also twins, namely D and J.
if you notice the hexagon on the left-hand-side, a hexagon has interior angles of 120° and if we take a peek at the vertex at D, it has two angles then, one interior or 120° and an exterior of 136°, a <u>full revolution</u> will be 360°, so the remaining angle in green there must be 360° - 120° - 136° = 104°, and her twin at vertex J is also 104°.
Numbers that are not decimals are whole numbers
-5z + 4n + 18z -10n
Combine like-terms
13z -6n
Your answer is A.) 13z - 6n.
Answer:
The required hypothesis to test is and .
Step-by-step explanation:
Consider the provided information.
It is given that the nightclub has recently surveyed a random sample of n = 250 customers of the club.
She would now like to determine whether or not the mean age of her customers is over 30.
Null hypotheses is represents as . Thus the null hypotheses is shown as:
The alternative hypotheses is represents as . Thus the alternative hypotheses is shown as:
Hence, the required hypothesis to test is and .
The pelican is 16 feet ABOVE the water, then dives 20 feet to get to the fish. Basically, just do 20 minus 16, which would be 4 feet. So the pelican is 4 feet below sea level.
