Answer:

-5

Step-by-step explanation:

The number line is saying that the solution could be any number less than -2.

The value included in the solution set for the inequality graph on the number line is -5.

The number line represents an inequality graph.

Let's use the range of value on the graph as x.

Therefore, the inequality on the number line will read as follows:

x < -2

Hence,

x less than -2 includes -3, -4, -5, -6, -7, -8 ..

Therefore, the value included in the solution set for the inequality graph on the number line is -5.

Step-by-step explanation:

The relaxation of any Linear Programming problem, consists of eliminating the integer constraint condition, keeping the original constraint and the objective function, solving the problem as continuous variables. If in such new condition we find that optimal solution consist of integer solution we have found optimal solution already, if not we need to go ahead with the branching procedure of making variables integer above and down of the fractional values.

In this particular case ( see GeoGebra graphic solution attached changing x₁ and x₂ by x and y respectively ), and Objective Function in red we got integer solution :

z(max)  = 11

x₁  = x  = 2

x₂ = y  = 1

Step-by-step explanation:

Answer:

# of laps < 28, the number of laps will be less than 28.

1 lap = 4 minutes

28 laps = 112 minutes

Because we want less than 28 laps,

27 laps = 108 minutes

She can run any amount of laps less than 28.

Answer:

x = 14

NP = 3.66

NL = 8.01

Step-by-step explanation:

since △NPQ ∼ △NLM

<L = <P

3x + 18 = 60

3x = 60 - 18

3x = 42

x = 42/3

x = 14

Similarly;

PN/PL = QN/QM

y/8 = 3.2/7

Cross multiply

7y = 3.2* 8

7y = 25.6

y = 25.6/7

y = 3.66

Hence NP = 3.66

Also

NP/NQ = NL/NM

3.66/3.2 = NL/7

3.2NL = 7 * 3.66

3.2NL =  25.62

NL = 25.62/3.2

NL = 8.01

Two triangle are similar if they have the same ratio of the corresponding sides and equal pair of corresponding angle. The value of the x is 14 degrees, the length of the NP is 3.7 cm (round to the nearest hundred), and the length of the NL is 8 cm ( round to the nearest hundred).

The given tingle NPQ and triangle NLM are the similar triangle.

The length of the line PL is 8 cm.

Two triangle are similar if they have the same ratio of the corresponding sides and equal pair of corresponding angle.

Value of the x-

As the two triangle are similar triangle, thus the length of the angle P is equal to the angle L. Therefore,

[tex]\angle L =\angle P\\ [/tex]

Keep the value of the angle from the diagram,

[tex]\begin{algined}\\ 3x+18&=60\\ 3x&=60-18\\\\ 3x&=42\\ x&=\dfrac{42}{3} \\ x&=14\\ \end[/tex]

Thus the value of the x is 14.

The length of the NP.

In the similar triangle the following ratios are equal,

[tex]\dfrac{PN}{PL} =\dfrac{QN}{QM} [/tex]

Put the values from the diagram,

[tex]\begin{aligned} \dfrac{y}{8}&=\dfrac{3.2}{7} \\ y&=\dfrac{3.2}{7} \times 8\\ y&=3.66\\ \end[/tex]

Value of y is equal to the length NP. Hence the length of the NP is equal to the 3.66 cm.

The length of the NL-

In the similar triangle the following ratios are equal,

[tex]\dfrac{NP}{NQ} =\dfrac{NL}{NM} [/tex]

Put the values from the diagram,

[tex]\begin{aligned} \dfrac{3.66}{3.2}&=\dfrac{NL}{7} \\ NL&=\dfrac{3.66}{3.2} \times 7\\ y&=8.01\\ \end[/tex]

Thus the length of the NL is equal to the 8.01 cm.

Hence the value of the x is 14 degrees, the length of the NP is 3.7 cm (round to the nearest hundred), and the length of the NL is 8 cm ( round to the nearest hundred).

Step-by-step explanation:

Sally bank account had a beginning balance of 230

She made two deposits of 50 and 420

50+420

= 470

She made a withdrawal of 190

Therefore her balance at the end of the month can be calculated as follows

470+230

= 700

= 700-190

= 510

Hence the balance at the end of the month is 510

Answer: The data is a random sample from the population of interest. Individual observations can be considered independent.

Step-by-step explanation:

The condition for constructing this confidence interval :

A) The data is a random sample from the population of interest.

C) Individual observations can be considered independent.

The correct options are A and C.

A confidence interval is a range of values that are constrained by the statistic's mean and that are likely to include an unidentified population parameter. The proportion of likelihood, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn several times is referred to as the confidence level.

Answer:

[tex]Ship\ A = 40\ miles[/tex]

[tex]Ship\ B = 30\ miles[/tex]

Step-by-step explanation:

Given

[tex]d = 50[/tex] --- distance apart

[tex]Ship\ B = x[/tex]

[tex]Ship\ A = x + 10[/tex]

The question can be represented with the attached image.

Required

Solve for x

Using Pythagoras theorem, we have:

[tex]x^2 + (x + 10)^2 = 50^2[/tex]

Open bracket

[tex]x^2 + x^2 + 20x + 100 = 2500[/tex]

Collect like terms

[tex]x^2 + x^2 + 20x + 100 - 2500 = 0[/tex]

[tex]2x^2 + 20x -2400 = 0[/tex]

Divide through by 2

[tex]x^2 + 10x -1200 = 0[/tex]

Expand

[tex]x^2 + 40x - 30x -1200 = 0[/tex]

Factorize

[tex]x(x + 40) - 30(x +40) = 0[/tex]

Factor out x + 40

[tex](x - 30)(x +40) = 0[/tex]

Split and solve for x

[tex]x - 30 = 0\ or\ x + 40 = 0[/tex]

[tex]x = 30\ or\ x = -40[/tex]

Distance can not be negative

So:

[tex]x = 30[/tex]

Recall that:

[tex]Ship\ B = x[/tex]

[tex]Ship\ A = x + 10[/tex]

This implies that:

[tex]Ship\ B = 30\ miles[/tex]

[tex]Ship\ A = 30 + 10\ miles[/tex]

[tex]Ship\ A = 40\ miles[/tex]
