Answer: Great more than happy to help!
Exponents come 2nd in line for PEMDAS (order of operations).
Once you finish the parenthesis, you move on to the exponents.
Step-by-step explanation:
55/20 = 2.75
It costs $2.75 per person
Answer: -9/-11
You use the equation y2-y1/x2-x1
9-18/-3–8
-9/-11
Answer: 1/257300
Step-by-step explanation:
Let S= total number of sample space
Let D= defective parts
Let ND= Non- defective parts
Let Pr(D) = probability of defective parts in the box
Let Pr(ND) = PROBABILITY OF non-defective parts
S= 250
D = 5
ND= 250 – 5
= 245
Pr(D) =5/250
= 1/50
Pr(ND) = 245/250
= 49/50
The probability of picking 3 parts that will be defective without replacement is
Pr(D₁) n Pr(D₂) n Pr(D₃)
Pr(D₁) = 5/250
Pr(D₂) = 4/249
Pr(D₃) = 3/248
= 5/250 × 4/249 × 3/248
= 60/15438000
= 1/257300
