Complete question :
It is estimated 28% of all adults in United States invest in stocks and that 85% of U.S. adults have investments in fixed income instruments (savings accounts, bonds, etc.). It is also estimated that 26% of U.S. adults have investments in both stocks and fixed income instruments. (a) What is the probability that a randomly chosen stock investor also invests in fixed income instruments? Round your answer to decimal places. (b) What is the probability that a randomly chosen U.S. adult invests in stocks, given that s/he invests in fixed income instruments?
Answer:
0.929 ; 0.306
Step-by-step explanation:
Using the information:
P(stock) = P(s) = 28% = 0.28
P(fixed income) = P(f) = 0.85
P(stock and fixed income) = p(SnF) = 26%
a) What is the probability that a randomly chosen stock investor also invests in fixed income instruments? Round your answer to decimal places.
P(F|S) = p(FnS) / p(s)
= 0.26 / 0.28
= 0.9285
= 0.929
(b) What is the probability that a randomly chosen U.S. adult invests in stocks, given that s/he invests in fixed income instruments?
P(s|f) = p(SnF) / p(f)
P(S|F) = 0.26 / 0.85 = 0.3058823
P(S¦F) = 0.306 (to 3 decimal places)

What does the motif of light represent in the excerpt and in the rest of the story?
A. death and dying
B. different versions of reality
C. punishment for one’s mistakes
D. life during wartime
Answers
The right answer is B, different versions of reality.
What does motif of light represents?
In the excerpt, the motif of light represents hope and the possibility of escape from death. The protagonist has just fallen into the water after the rope broke, and he is struggling to stay alive.
He sees a distant light and realizes that he is rising to the surface, which gives him hope. Throughout the story, the motif of light represents the protagonist's desire for freedom and escape from death.
As he imagines various scenarios in which he could escape, such as swimming to safety or running away, he often associates them with a "gleam of light."
In "An Occurrence at Owl Creek Bridge," the motif of light serves as a recurring symbol for the protagonist's desire for freedom and escape from death.
The protagonist, Peyton Farquhar, is a Confederate sympathizer who has been condemned to hang by Union soldiers during the Civil War. As he awaits his execution, he imagines various scenarios in which he could escape or evade capture, such as swimming to safety or running away.

Answer:
Give brainliest please! The answer is 53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is hours.
Use formula:
where
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours

the maximum value is achieved when A, D and C are collinear and the quadrilateral ABCD becomes an isosceles triangle ABC
base AB = 52 and vertical angle 2x + 34°
For the sine law
(sin 2x)/22 = (sin ADB)/AB
(sin 34°)/30 = (sin BDC)/BC
is given that AB = BC, and sin ADC = sin BDC because they are supplementary, so from
(sin ADC)/AB = (sin BDC)/BC
it follows
(sin 2x)/22 = (sin 34°)/30
sin 2x = 22 (sin 34°)/30
2x = asin(22 (sin 34°)/30) ≈ 24.2°
x = 0.5 asin(22 (sin 34°)/30) ≈ 12.1°
0 < x < 12.1°
