<span>Probability that a person is math phobic = 19% = 19/100
a) the probability that both are nervous around strangers</span>
<span>P (A)
= 19/100 * 19/100
= 361/10000
= 0.0361</span>
<span>
b) The probability that both are not nervous around strangers</span>
<span>P (B) = 81/100 * 81/100
= 0.6561</span>
<span>
The probability that at least one person is nervous around strangers i.e. P'(B)
= 1 - P(B)
= 1 - 0.651
= 0.3439</span>
now one denominator is x^2 + 8x + 15
if we factorise then (x +3)(x +5)
now in expressions which have like x+3 as denominator ...you multiply and divide them by x+5 and once u get denominator equal you can add numerator easily
Answer:

Y = sec(x) has a range that doesn’t include 0.
30.63 for 3 sets of pencils......that means each set cost (30.63 / 3) =
10.21....so the change in his account for 1 set of pencils is -$ 10.21 <=
