Answer:
0.430
Step-by-step explanation:
Product has four parts :
For proper functioning, each part must function :
Let the 4 parts be:
A, B, C and D
Proper functioning probability :
A and B = 0.79
C and D = 0.83
For proper functioning :
P(A) * P(B) * P(C) * P(D)
0.79 * 0.79 * 0.83 * 0.83
= 0.42994249
= 0.430
If you round 13.245 seconds to the nearest tenth, the answer is 13.2 seconds.

Hey! </em></h3>
<u>let the numbers be n and m</u>
<u>n+m=65</u>
<u>n=4m</u>
<em>So when we put our work in:</em>
<u>4m+m=65</u>
<u>5m=65</u>
<u>m=13</u>
<u>n=52</u>
So therefore your two numbers are 52 and 13!
