Answer:
x=
−1
2
y+
25/2
Step-by-step explanation:
Let's solve for x.
2x+1y=25
Step 1: Add -y to both sides.
2x+y+−y=25+−y
2x=−y+25
Step 2: Divide both sides by 2.
2x
2
=
−y+25
2
x=
−1
2
y+
25
2
Sqrt(-2), can be written as i * sqrt(2). Thus, our answer is x - i sqrt(2).
The probability that exactly six out of ten carry a smartphone when travelling is; <u><em>P(6) = 0.146</em></u>
The missing part of the question is;
The probability distribution of x is the binomial distribution with n = 10 and p = 0.75.
Calculate P(6)
- This is a binomial <em>probability distribution</em> problem that has a general formula as; P(x) = ⁿCₓ × pˣ × q⁽ⁿ ⁻ ˣ⁾
Where;
p is probability of success
q is probability of failure
n is number of experiments
In this question;
n = 10
p = 75% = 0.75
q = 1 - p
q = 1 - 0.75
q = 0.25
Since six passengers are randomly selected, then applying the formula earlier quoted, we have;
P(6) = ¹⁰C₆ × 0.75⁶ × 0.25⁽¹⁰ ⁻ ⁶⁾
P(6) = 0.146
