I can’t find the question what is it
Answer:
The probability of Sam is 2/5
Step-by-step explanation:
n(e)=2
n(s)=5
Pe=n(e)/n(s)
Pe=2=5
Answer:
B. 61
Step-by-step explanation:
The sum of arcs around a circle is 360°. This means ...
110° +128° +c° = 360°
c° = 122° . . . . . . . . . . . . . subtract 238°
__
An inscribed angle in a circle has half the measure of the arc it subtends.
a° = 1/2c° = 1/2(122°) = 61°
__
The other angles in the diagram are ...
b° = 1/2(110°) = 55°
d° = 1/2(128°) = 64°
Answer:
2 grams
Step-by-step explanation:
50 years is 5 half lives as 1 half life is 10 years.
64 divide 2 = 32-1 half life
32 divide 2 =16-2nd half life
16 divide 2 = 8-3rd half life
8 divide 2 = 4-4th half life
4 divide 2 = 2-5th half life
This means we will have 2 grams left of the radioactive substance after 50 years.
I'm not sure if that's x=4 or x= -4, but I'll solve both.
x=4:
11(4) - 4 = 44 - 4 = 40
x = -4:
11(-4) - 4 = -44 -4 = -48
Have an awesome day! :)
