Answer:
1/4
Step-by-step explanation:
numbers > 3 are 4,5,6
number of numbers >3=3(4,5,6)
probability=3/6=1/2
probability of drawing a head=1/2
reqd. probabilty=1/2*1/2=1/4
Using a system of equations, it is found that the equation that could be used to find the value of b is given by:
3×4−8=b
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
Fatima has 3 packs of batteries. Each pack contains 4 batteries, hence:
b = 3 x 4
She gives her brother 8 batteries to put in his toy robot, hence:
b = 3 x 4 - 8
Which means that the first expression is correct.

Answer:
r = 8 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
50.24 = 2 * (3.14) *r
50.24 = 6.28r
Divide each side by 6.28
50.24/6.28 = r
8 =r
The values of K is 10
