An airline reports that 85% of its flights arrive on time. To find the probability that its next four flights into LaGuardia Air

port all arrive on time, can we multiply (0.85)(0.85)(0.85)(0.85)? Why or why not?

Answer:

The answer is "no".

Step-by-step explanation:

No, because the probability besides simultaneous flights to arrive on time are not self-sufficient for every flight (when the first flight was late, therefore the probabilities during the next flight were significantly greater), because then the standard multiplication principle would be used for explanatory variables.

A kite, flying 50 feet high in the air is attached by a string to a stake in the sand. How long is the string to the nearest ten
Vlad [161]
Height of the kite from the ground = 50 feet
Angle at which the kite is flying = 45 degrees
Let us assume the length of the string = x feet
Then
x = 50 * (square root 2)
   = 50 * 1.414
   = 70.7 feet
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "b".

kakasveta [241]

Answer:the side length of a square with the area 0.09 square meter is 0.3 meter.

Step-by-step explanation:

The side length of a square S can be determined by the formula S equals the square root of a where a represents the area of the square. It means that

S = √a

Therefore, the side length of a square with the area 0.09 square meter would be

S = √0.09 = 0.3 meter

How do you solve this??? I need it fast please help with steps.<br> (x+3)(x+1)^2(x−4)&gt;0
scZoUnD [109]

Answer:

  x < -3 or x > 4

Step-by-step explanation:

The product of the factors is 4th-degree, and the leading coefficient is 1 (positive).

The factors tell you the following about the zeros:

  x = -3 . . . sign change from + to -

  x = -1 . . . graph touches, but no sign change. - on either side of x=-1

  x = 4 . . . sign change from - to +

__

The function will be positive for x < -3 and for x > +4.

_____

<em>Additional comments</em>

The value of the function is zero when any of its factors is zero. The value of a factor changes sign when the value of x changes from one side of the 0 to the other. For example, here, we have x+1 as a factor, so x=-1 is a zero. When x = -0.9, the factor is positive (-0.9 +1 = 0.1). When x = -1.1, the factor is negative (-1.1 +1 = -0.1). If this factor were to the first power, it would cause the value of the function to change sign at x=-1.

However, the factor (x+1) has an even power: (x+1)^2. That means when the factor is negative, its square is positive, and when the factor is positive, its square is positive. In short, the factor (x+1)^2 causes the function to be zero at x=-1, but does not make the function change sign there.

The product of all of these factors will result in a polynomial with x^4 as the highest-degree term. That means the function is of even degree. The leading coefficient is 1, so is positive, and the function will generally have a U-shape. The left-most (odd-degree) zero will be where the function changes sign from positive to negative. The right-most (odd-degree) zero will be where the function changes sign from negative to positive. Those zeros are x=-3 and x=+4, respectively. There are no places between these where the function changes sign, so these zeros are the ends of the regions where the function is positive (>0).

The set of ordered pairs shown below defines a relation. (MAFS.912.F-IF.2.4){(0, 0), (1, 5), (2, 8), (3, 9), (4, 8), (5, 5), (6,
Ratling [72]

Using the range concept, it is found that the greatest element in the range of this relation is 9.

  • The range of a data-set is the set that contains all possible outputs.
  • The data-set has the format (x,y), in which the values of y are the outputs.

Hence, the range is: {0, 5, 8, 9}.

  • From the given range, the greatest element is 9.
