Which answer shows a balanced nuclear equation for the beta decay of potassium-42?

Explanation:

In Beta decay unstable nuclei will convert into stable nuclei by converting its neutron into an electron and a proton.

this process is given as

so in this process mass number will remain same but atomic number will increased by 1

So the new nuclei is of higher atomic number

So we will have

so above is the nuclear reaction

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
