Which ordered pair is in the solution set of the system of linear inequalities? y >3/2 x – 1 y <3/2 x – 1 (–5, 2) (2, 2) (
Vikentia [17]

Answer:

No solution

Option 4 is correct

Step-by-step explanation:

Given: The system of inequality

y>\dfrac{3}{2}x-1

y

We need to choose correct option.

Option 1: (-5,2)

Put x=-5 and y=2

Equation 1                               Equation 2

2>\dfrac{3}{2}(-5)-1                            2

2>-8.5                                    2

    TRUE                                     FALSE

Option 2: (2,2)

Put x=2 and y=2

Equation 1                              Equation 2

2>\dfrac{3}{2}(2)-1                    2

2>2                                           2

  FALSE                                      FALSE

Option 3: (5,2)

Put x=-5 and y=2

Equation 1                            Equation 2

2>\dfrac{3}{2}(5)-1                      2

2>6.5                                           2

 FALSE                                      TRUE

Option 1, 2 and 3 are incorrect because both equation must be true for solution.

Hence, Option 4 is correct no solution.

Vsevolod [243]

Answer:

D. 5 inches

Step-by-step explanation:

Given:

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter.

That means complete angle having 360° is divided into 3 section.

The central angle formed by the peach cobbler is 105 degrees.

The central angle formed by the pasta is 203 degrees.

<u>Question asked:</u>

What is the approximate length of the arc of the section containing the peas?

<u>Solution:</u>

The central angle formed by the peas = 360° - 105° - 203°

                                                                = 52°

Ridius,r=\frac{Dameter}{2} =\frac{12}{2} =6\ inches

As we know:

Length\ of\ arc=2\pi r\times\frac{\Theta }{360}

                        =2\times\frac{22}{7} \times6\times\frac{52}{360} \\ \\ =\frac{13728}{2520} \\ \\ =5.44\ inches

Therefore, the approximate length of the arc of the section containing the peas are 5 inches.

kenny6666 [7]

Answer:

The required probability is, \simeq 0.06729

Step-by-step explanation:

Of 24 employees at a local supermarket, 13 work as cashiers  and 11 stock shelves. If 4 employees are selected at random to work overtime, then

P( all 4 are cashiers) = \frac{^{13}{C}_{4}}{^{24}{C}_{4}}

                                 \simeq 0.06729
