PLZ HELP QUICK!!!!!!..... Figure ABCD has vertices A(−4, 1), B(2, 1), C(2, −5), and D(−4, −3). What is the area of Figure ABCD?

n200080 [17]

Answer:

The area = 30 units²

Step-by-step explanation:

∵ A (-4 , 1) and (2 , 1)

∴ AB is a horizontal segment (same y-coordinates)

∴ AB = 2 - -4 = 6 units

∵ B (2 , 1) and C (2 , -5)

∴ BC is a vertical segment (same x-coordinates)

∴ AB ⊥ BC

∴ BC = 1 - -5 = 6 units

∵ A (-4 , 1) and D (-4 , -3)

∴ AD is a vertical segment

∴ AD ⊥ AB

∴ AD // BC

∴ AD = 1 - -3 = 4 units

∴ ABCD is trapezium with parallel bases AD , BC and height AB

∵ $A=\frac{b_{1}+b_{2}}{2}h$

∴ $A=\frac{4+6}{2}(6)=30$ units²

1.5.5 Practice: Modeling: Best Ticket Deal

posledela

The best ticket deal are illustrations of linear equations

The ticket system is a better deal to the max ticket

<h3>How to determine the best ticket deal</h3>

From the complete question, we have the following summary:

Ticket System

Charges = $22 per person

Surcharge = $10 per transaction

Max Tickets

Charges = $20 per person

Surcharge = $16 per transaction

Assume there would be only one transaction, the linear equations that represent the ticket deals are:

Ticket System: y = 22x + 10

Max Ticket: y = 20x + 16

The costs of ticket for two people in both deals are:

Ticket System: y = 22*2 + 10 = 54

Max Ticket: y = 20*2 + 16 = 56

By comparison;

54 is less than 56

This means that the ticket system is a better deal to the max ticket

An opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign. How many pe

77julia77 [94]

Answer:

The number of people would have participate in opinion poll

n = 15,267

Step-by-step explanation:

Step(i):-

Given data an opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign.

Given proportion = 36% =0.36

Given the margin of error = 1% =0.01

Level of significance = 99% 0 r 0.01

Z₀.₀₁ = 2.576

step(ii):-

The margin of error of Population proportion is determined by

$M.E = \frac{Z_{0.01} \sqrt{p(1-p)} }{\sqrt{n} }$

$0.01 = \frac{2.576 \sqrt{0.36(1-0.36)} }{\sqrt{n} }$

$\sqrt{n} = \frac{2.576 \sqrt{0.36(1-0.36)} }{0.01 }$

√n = 123.648

Squaring on both sides , we get

n = 15,267

final answer:-

The number of people would have participate in opinion poll

n = 15,267
