c. √2
d. √-1

Answers

Answer 1
Answer: If you would like to know which value is equivalent to |f(i)|, you can calculate this using the following steps:

f(x) = 1 - x
|f(i)| = |1 - i| = sqrt((1-i) * (1-i)^conjugate) = sqrt(2) = √2

The correct result would be c. √2.

Two urns each contain green balls and blue balls. Urn I contains 4 green balls and 6 blue balls, and Urn II contains 6 green balls and 2 blue balls. A ball is drawn at random from each urn. What is the probability that both balls are blue?A. 2/51
B. 3/20
C.1/10
D.4/153

Answers

b- 3/20. first, add up the number of balls in each urn. 
urn 1- 10
urn 2- 8
then, make a fraction where the numerator is the number of blue balls in the urn and the denominator is the total number of balls
urn 1- 6/10 (simplified to 3/5)
urn 2- 2/8 (simplified to 1/4)
finally, multiply your two probabilities and simplify
1/4*3/5=3/20

Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. What was the price of Zoe’s dinner before sales tax and tip?

Answers

Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

  • Sales tax = 11% * original price = 0.11 * x= 0.11x
  • Tips for dinner = 20% * original price = 0.20 * x = 0.2x
  • 0.11x + 0.2x = 18.60
  • 0.31x = 18.60
  • x = 60
  • $60 was the price of Zoe's dinner, before sales tax and tip.

Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

1. Sales tax = 11% times original price = 0.11 times x= 0.11x

2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x

3. 0.11x + 0.2x = 18.60

4. 0.31x = 18.60

5. x = 60

6. $60 was the price of Zoe's dinner, before everything else
