Answer:
Concept: Algebraic Analysis
- Those two symbols indicate one solution
- Those symbols indicate a range of values
- Indicates two bounded answers
- In an inequality there is always a solution
65 divided by 7 is approximently 9, and 25 divided by 7 is approximently 3, so 9 plus 3 is 12, so Gracie must wash 12 cars to earn enough money to save 25 and spend 65!
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
Answer:
¾
Step-by-step explanation:
Length of Kerry string = 7(½) = 15/2
