I believe it’s D because the notation should be outside the parenthesis
<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>

Answer:
x = 4
Therefore, for the triangles to be congruent by HL, the value of x must be 4.
Step-by-step explanation:
Given: ΔABC and ΔHGL are congruent. ∠ABC = ∠HGL = 90°.
Length of hypotenuse AC = 15
Length of hypotenuse HL = 3x + 3
Length of AB = 9, Length of BC = 12 and Length of GL = 2x + 1.
Sol: ∵ ΔABC ≅ ΔHGL
Length of HL = Length of AC (corresponding parts of congruent triangles)
3x + 3 = 15
3x = 15 - 3
3x = 12
x = 12/3 = 4
Therefore, for the triangles to be congruent by HL, the value of x must be 4.
