The event that represents a "success" is (a) US adults who feel the American dream is out of reach
<h3>How to determine the success event?</h3>
From the question, we have:
p = 11%
The variable represents the proportion of US adults that feel the American dream is out of reach.
This represents the probability of success.
Hence, the event that represents a "success" is (a) US adults who feel the American dream is out of reach
<h3>Why is x a binomial random variable?</h3>
A binomial random variable can only take any two values
This means that x is a binomial random variable because (b) there are only two possible outcomes.
<h3>The value of p for the binomial event</h3>
In (a), we have:
p = 11%
Hence, the value of p for the binomial event is 11%

Chi would have two thousand nickels because if 100 nickels is 5% and 100 divided 5 is 20 so a 100 times 20 is 2000
Y = 6x
4x + y = 7
(substitute y = 6x in the ‘y’ spot in 4x + y = 7)
4x + 6x = 7
10x = 7
/10 on both sides
x = 7/10
(substitute x = 7/10 in the ‘x’ spot in either of the two equations)
y = 6x
y = 6(7/10)
y = 4.2 = 21/5
Answer:
x = 7/10
y = 21/5
Step-by-step explanation:
1.√2×(-2√9)×(-√2)
= -2×(-2×3)
=12 option a
2. √5×√15×√75
= √5×(√3√5)×(5√3)
= 5×3×5
=75 option b
Answer:
Between 1 and 3 seconds
Step-by-step explanation:
There is no change in distance ( change in y ) between 1 and 3, so she wasn't walking during that time
