Answer:
$20,001
Step-by-step explanation:
Let $x be the amount of dollars Lincoln needs to make in sales to earn more than $1500.
His boss pays him $500 for the week, plus a 5% commission on each vehicle he sells.
5% of $x is $0.05x, the Lincoln earns
in total.
Hence,
Solve this inequality:
Lincoln needs to make in sales more than $20,000, so the minimum amount of dollars Lincoln needs to make in sales is $20,001

Answer:
Expected number of visits to the emergency room that would require a surgery is 336.
Step-by-step explanation:
Let <em>X</em> = number of surgery.
The odds of having a surgery in a randomly selected visit to a emergency room is 4 out of 10.
Then the probability of having a surgery in a randomly selected visit to a emergency room is:
In the past month a large urban hospital had 840 emergency visits.
An emergency room visit may lead to surgery or not is independent of the others.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 840 and <em>p</em> = 0.40.
The expected value of a binomial random variable is:
Compute the expected number of visits that would require a surgery as follows:
Thus, expected number of visits to the emergency room that would require a surgery is 336.
10/25 = 2/5 Because you divide both sides by 5

Answer:
∠XWY = 58°
∠YXZ = 32°
∠WVZ = 116°
∠XWZ = 90°
∠XZY = 58°
Step-by-step explanation:
Triangle VWX is isosceles. Its base angles are (180° -64°)/2 = 58°.
∠XWY = 58°
The other corner angles are the complement of this.
∠YXZ = 32°
The obtuse angles at V are the supplement of the one marked
∠WVZ = 116°
We assume the figure is a rectangle, so each full corner angle is a right angle.
∠XWZ = 90°
The remaining angle of interest is congruent to the first angle of interest.
∠XZY = 58°
