Answer:
The probability of the frog landing on a complement of yellow lily is 0.57
Step-by-step explanation:
PLANTS Of the water lilies in the pond, 43% are yellow. The others are white.
It is given that 43% of plants are lilies it means the probability of a frog randomly jumping onto a lily is:
the probability of the frog landing on a complement of yellow lily is 0.57
Answer: b. helium nucleus
Helium nucleus is the particle that is being emitted in an alpha radiation. This helium nucleus then transforms and becomes decays that are also known as alpha decays. The alpha particle maybe similar to helium nucleus however, it does not have electrons surrounding it.
Answer:
0.670. M
Step-by-step explanation:
Molarity can be expressed like this:
molarity
= number of moles
/volume (L)
We know the volume, which is 2.37 L
, but we need to find the number of moles. We can do this by dividing 67.3 g by the molar mass of L
i
C
l
:
number of moles =
mass of sample
/molar mass
number of moles = 67.3 g
/(6.94 + 35.45) g/mol =
67.3 g
/42.39 g/mol
number of moles = 1.59 mol
molarity
=
1.59 mol
/2.37 L
= 0.670. M
Answer: zoe's question's data would vary because not everyone in her class could play video games for the exact same amount of time.
however this is not a statistical question because we do not know when the students are playing video game for example we wouldnt know if she wanted to know how much time a classmates spends playing video games each year, each month, each week, etc. so to make this a statistical question zoe would have to ask.... which student spends the most time a day on video games.
hope this helps ;D
