Answer:
so bro imma help you
Step-by-step explanation:
the answer is 37/12
mixed number form is 3 1/12
decimal form is 3.083
34 and -14 as proven here:
Sum: 34 + -14 = 20
Difference: 34 - -14 = 48
just the opposite (when it says negative it gonna be positive)
Answer:
x=3

Hope this help and plz give me brainlist.
Answer:
(1, -1)
Step-by-step explanation:
Answer:
0.5 ; 0.475 ; 0.689 ; 0.4013
Step-by-step explanation:
Given that:
Rate of production of defective batteries p = 0.05
Number of batteries produced (n) = 10
The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries
Variance of defective batteries :
Var(X) = n * p * q ; q = 1 - p
Hence,
Var(X) = 10 * 0.05 * 0.95 = 0.475
Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689
Probability that atleast 1 battery is defective :
Using the binomial probability function
P(x ≥ 1) = 1 - p(x = 0)
= 1 - q^n
= 1 - 0.95^10
= 1 - 0.59873693923837890625
= 0.40126306076162109375
= 0.4013
