The probability that the flight would leave on time when it is not raining is: 0.522

Probability is the likelihood of an event happening or not.

Analysis:

pr( it will rain) = 0.18

Pr( it will not rain) = 1 - 0.18 = 0.82

Pr ( flight will be delayed) = 0.14

Pr( it will not be delayed) = 1 - 0.14 = 0.86

Pr( it will not rain and flight would leave early) = 0.74

Pr( flight leave early when not raining) = pr( it willnot rain) x Pr( it will not be delayed) x Pr( it will not rain and flight leave on time) 0.82 x 0.86 x 0.74 = 0.522

In conclusion, the probability that flight would leave on time when it is not raining is 0.522

Answer:   The answer to your question is Cost of a serving = $0.62

Step-by-step explanation:

Data

diameter = 3.5 in

height = 5 in

each serving = 15 in³

Cost of the can = $1.99

Process

1.- Calculate the volume of the can

Volume = πr²h

-Substitution

Volume = (3.14)(3.5/2)²(5)

-Simplification

Volume = (3.14)(3.062)(5)

-Result

Volume = 48.08 in³

2.- Use proportions and cross multiplication to find the cost of a serving.

                  48.08 in³ ---------------- $1.99

                        15  in³ ----------------  x

                         x = (15 x 1.99)/48.08

                         x = 29.85/48.08

                         x = $0.62

Answer:

Step-by-step explanation:

An equation is solved for one of the variables by undoing the operations done on that variable. Here, we can solve for 'a' and solve for 'b' to find the desired values.

__

Solve for 'a', then substitute the value of 'b'.

  [tex]\sqrt{9a}=\dfrac{b^2-3}{2}\\\\9a=\left(\dfrac{b^2-3}{2}\right)^2=\dfrac{(b^2-3)^2}{4}\\\\a=\dfrac{(b^2-3)^2}{36}=\dfrac{((-3)^2-3)^2}{36}=\dfrac{6^2}{36}\\\\\boxed{a=1}[/tex]

Answer: The 4th option= -1, -3

Step-by-step explanation: Here, if y = -1 and x = -3. The equation would be: (-1) + (-3)= -1 -3 = -4

Now we know that -4 is greater than -5.

Some may think that -4 is smaller than -5 nut remember that the numbers are in minus form, so if u put them in a number line, then -4 is greater than -5.

Answer:

just look at the algebra formula and simplify to get your answer. Remember to use your powers well

Answer:

Perimeter = 56 m

Area = __ m^2

Step-by-step explanation:

Perimeter = ___ m

Area = __ m^2

To find Perimeter, you have to add up all the sides of the shape,

5 + 5 + 5 + 11 + 7 + 7 + 16

= 56 m

Perimeter = 56 m

To find area, you have to multiply length times width,

5 × 5 = 25

7 × 16 = 112

112 + 25 = 137

Area = 137 m^2

Therefore the perimeter of this shape is 56 m and the area of this shape is 137m^2.

Answer: A

Step-by-step explanation:

On a reflection through the x-axis, the x-coordinate of the point will not change, but the y-coordinate will be changed with a negative sign.

So, the reflection of the point is: (8, -7)

Therefore, Option(a)(8, -7) is true.

Answer:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (3, 5) and r = , hence

(x - 3)² + (y - 5)² = (  )², that is

(x - 3)² + (y - 5)² =  ← equation of circle

Using the triangle proportionality theorem, the length of segment MF in triangle LMN is: 48 cm.

The triangle proportionality theorem states that when a segment intercepts two sides of a triangle and it is parallel to a third side, then it divides the side proportionally.

The diagram of triangle LMN is shown below. Using the triangle proportionality theorem, we have:

MF/MN = ME/ML

Plug in the values

MF/124 = (31 - 19)/31

MF/124 = 12/31

MF = (12 × 124)/31

MF = 48 cm

Answer:

  about 1.3885 miles ≈ 7331 ft

Step-by-step explanation:

The height of the helicopter can be found using the tangent relation, which we know relates the sides and angles of a right triangle by ...

  Tan = Opposite/Adjacent

__

With reference to the attached diagram, the above relation can be used to find the lengths of AC and BC, which we know total 4 miles.

  tan(28°) = h/AC   ⇒   AC = h/tan(28°) = h·tan(90° -28°) = h·tan(62°)

  tan(45°) = h/BC   ⇒   BC = h/tan(45°) = h·tan(90° -45°) = h·tan(45°)

The total distance between A and B is then ...

  AB = AC +BC

  4 = h·tan(62°) +h·tan(45°) = h(tan(62°) +tan(45°))

Dividing by the coefficient of h, we have the value of h:

  h = 4/(tan(62°) +tan(45°)) = 4/(1.88073 +1) ≈ 1.38854 . . . . miles

In feet, that is ...

  (1.38854 mi)(5280 ft/mi) = 7331 ft

The height of the helicopter is 1.38854 miles, or 7331 feet.

Step-by-step explanation:

mean value : the sum of the measurements of all 10 plants divided by 10 (the number of measurements).

A)

since the 2 measurement errors are compensating each other in the sum of measurements (-5 cm vs. +5 cm), the sum stays the same, the number of measurements stays the same (10), so the mean value stays the same (72 cm).

B)

the mean absolute deviation was the mean value of the absolute values of the differences of each measurement to the plant measurements.

since the mean value stayed the same, so did the difference of the 8 originally correct measurements to that mean value.

the only change is with the 2 corrected measurements.

the original (but wrong) measurement of 65 had a difference of 7 (to 72).

and now it is only 2 (70 to 72).

and the other one had a difference of 6 (72 to 78).

and now it is only 1 (73 to 72).

so, the sum of all the differences decreased by (7-2) + (6-1) = 5 + 5 = 10.

we had originally a mean absolute deviation of 8.5. the sum of all 10 original differences was therefore 8.5×10 = 85.

now this sum went down to 85-10 = 75.

and the new mean absolute deviation is 75/10 = 7.5.
