Hence, the required inequality is x+y≤4, 7x+4y≤1150

inequality, In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Let x be the number of adults and y be the number of campers.

There are rooms for 450 people, so

x+y≤450.

Each adult costs $7, then x adults cost $7x.

Each camper costs $4, then y campers cost $4y.

There is a maximum budget of $1,150, so

7x+4y≤1,150

Hence, you get the system of two inequalities:

         x+y≤4

The distance from Platform B to Platform C is 26.926 units

The given parameters are;

The zip-line course distance from platform A to platform F is given;

On the given graph of the path of travel we have;

Coordinates of the point B = (-25, -20) and the coordinates of the point C = (-15, 5).

The distance between two points with coordinates (x₁, y₁) and (x₂, y₂) is given by the formula

[tex]l=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Therefore, the distance between B and C is found by substituting (-25, -20) = (x₁, y₁) and (-15, 5) = (x₂, y₂)

Which gives

[tex]l=\sqrt{(5-(-20))^2}+((-15)-(-25))^2\\l=26.926 units[/tex]

Using the normal distribution, it is found that there is a 0.4038 = 40.38% probability that the person has an IQ score between 92 and 108.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 100, \sigma = 15[/tex].

The probability that the person has an IQ score between 92 and 108 is the p-value of Z when X = 108 subtracted by the p-value of Z when X = 92, hence:

X = 108:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{108 - 100}{15}[/tex]

Z = 0.53

Z = 0.53 has a p-value of 0.7019.

X = 92:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{92 - 100}{15}[/tex]

Z = -0.53

Z = -0.53 has a p-value of 0.2981.

0.7019 - 0.2981 = 0.4038.

0.4038 = 40.38% probability that the person has an IQ score between 92 and 108.

In which:

Researching the problem on the internet, the data-set is given as follows:

104, 102, 103, 105, 125, 106, 107, 110, 110, 95, 108, 86, 112, 101, 101.

Answer:

Step-by-step explanation:

The formula for finding the perimeter is 2w+2L (2*width + 2*length)

So, since we know the width is "w" and the length is "3w-2", we can just substitute those into the equation.

2(w)+2(3w-2)

From there, if needed, you can simplify to:

2w + 6w-4

Add like terms:

Step-by-step explanation:

The sides opposite and adjacent to the given angle are shown in this right triangle. The relation between them is given by the tangent trig function:

  Tan = Opposite/Adjacent

  tan(63°) = 1/x

We can multiply this equation by x/tan(63°) to find the value of x:

  x = 1/tan(63°) ≈ 1/1.96261 ≈ 0.509525

The length x is about 0.5 units.

The graph of f(x) + 1 is the graph in the option C.

For a given function f(x), a vertical translation is written as:

g(x) = f(x) + N

Here we have g(x) = f(x) + 1, so we have a translation of 1 unit upwards, the graph of f(x) + 1 is the graph of f(x) but translated one unit upwards.

Step-by-step explanation:

a. y = 85x + 50

The rule of the points is y = 3.2x - 0.7

The points are given as:

(-2,-7) (0,-1) (7, 22)

The above points form an approximate linear equation.

So, we make use of a linear regression to determine the rule

When the above points are entered in a statistical calculator, we have the following summary:

The regression equation is then represented as:

y = bx + a

Where

b = SP/SSX = 144.67/44.67 = 3.23881

a = MY - bMX = 4.67 - (3.24*1.67) = -0.73134

This gives

y = 3.23881x - 0.73134

as x → ∞; f(x) → -∞

as x → -∞; f(x) → ∞
