Police plan to enforce speed limits by using radar traps at four different locations within the city limits. The radar traps at
dalvyx [7]

Answer:

The probability that the person gets a speeding ticket is 0.27

Step-by-step explanation:

The probability that the person receives a speeding ticket is the probability that the person passes through any of the speed limits and the radar is operating at that time.

Let P(L_1) is the probability that the person passes through radar L_{1} and it is operating at that time is

P(L_{1})=P(1)\times P(2)

Where

P(1) is the probability of person passes through L_{1}

P(2) is probability that the radar is operating

P(L_1)=0.2\times 0.4=0.08

Similarly the probabilities are calculated for other radars in the similar manner as

P(L_2)=0.1\times 0.3=0.03

P(L_3)=0.5\times 0.2=0.1

P(L_4)=0.2\times 0.3=0.06

Thus the reuired probability of the reuired event is

P(E)=P(L_1)+P(L_2)+P(L_3)+P(L_4)\\\\P(E)=0.08+0.03+0.1+0.06=0.27

Write the quadratic equation whose roots are 3 and 1, and whose leading coefficient is 1
Serhud [2]

Answer:

x² - 4x + 3 = 0

Step-by-step explanation:

given roots x = a and x = b then the corresponding factors are

(x - a) and (x - b)

the equation is then the product of these factors , that is

(x - a)(x - b) = 0

given

roots x = 3 and x = 1 , then factors are (x - 3) and (x - 1) , then

(x - 3)(x - 1) = 0 ← expand factors using FOIL

x² - 4x + 3 = 0

The length of a rectangle is the sum of the width and 2. The area of the rectangle is 48 units. What is the length, in units, of
suter [353]

Length of the rectangle is 8 units

Step-by-step explanation:

  • Step 1: Find the length, let width be x.

Area of the rectangle = 48 units

Length = x + 2

⇒ Area = Length × Breadth

48 = x (x + 2)

48 = x² + 2x

x² + 2x - 48 = 0

x² + 8x - 6x + 48 = 0 (Product Sum rule to factorise)

x(x + 8) - 6(x + 8) = 0

(x - 6)(x + 8) = 0

⇒ x = 6, -8 (negative value is neglected)

∴ x = 6

x + 2 = 8
