Answer:
D.420
Step-by-step explanation:
400 *0.05 = 20 so adding it to 400 will equal to 420
The table below shows the outcome of tossing 3 coins
The probability of getting two heads is 3/8
If the three coins tossed 10000 times, the probability of exactly two heads appear is = (3/8) × 10000 = 3750 times
Arc XZ is marked in red (see the image attachment)
Angle XYZ is marked in blue
It turns out that angle XYZ is exactly half the measure of arc XZ. This is due to the inscribed angle theorem. Angle XYZ is an inscribed angle that cuts off, or subtends, arc XZ.
measure of arc XZ = 28 degrees
measure of angle XYZ = (1/2)*(measure of arc XZ)
measure of angle XYZ = (1/2)*(28 degrees)
measure of angle XYZ = 14 degreesAnswer: D) 14 degrees
They have the same number of valence electrons which, in general, gives them similar oxidation numbers and other similar chemical and physical properties. The similarities are most pronounced in the groups at either side of the standard periodic table, and are least pronounced for the transition and rare earth elements.
