1.25 is the probability that the aircraft Will last 100 hours.

The area of mathematics described as probability concerns with numerical representations of the likelihood that an event will occur or that an assertion is correct. An event's probability is a number between 0 and 1, where, roughly speaking, 0 indicates the event's impossibility and 1 represents certainty. 

Given Data

Mean = 80

Standard deviation = 16

P( x < 100)

P( x < 100) = P( Z< [tex]\frac{x- mean}{standard deviation}[/tex])

P(x<100 ) = P( Z < [tex]\frac{100-80}{16}[/tex])

P(x< 100) = P(Z< [tex]\frac{20}{16}[/tex])

P(x < 100) = 1.25

1.25 is the probability that the aircraft Will last 100 hours.

Step-by-step explanation:

The unit rate he can drive in mile per gallon is 22 miles per gallon.

Unit rate can be defined as the ratio between two measurements with the second term as 1.

In other words, a unit rate describes the ratio of two different units for the quantity of one.

Therefore, the  unit rate in miles per gallon can be calculated as follows:

Hence,

unit rate = number of miles / number of gallons

number of miles = 330 miles

number of gallons = 15 gallons

unit rate = 330 / 15

Therefore,

unit rate =  22 miles per gallon

The number of large cups that would contain the same amount as 10 1/2 small cups is 6.

From the information, it was stated that we should find the number of large cups that would contain the same amount as 10 1/2 small cups if a large cup holds 1 3/4 times the quantity of liquid that's in a small cup.

This simply means that we have to divide the values that are given. This will be illustrated as:

The probability of an event is the chance or the likelihood that the event would occur.

Note that the chance or the likelihood is represented as a numerical value

The complete question is added as an attachment

From the attached question, we have the following parameters

P(White Vehicle) = 0.25

P(Car) = 0.36

P(White Car) = 0.08

Using the complement rule of probability, we have the following equation

P(White Car) + P(Not White Car)  = 1

Substitute the known values in the above equation

So, we have the following equation

0.08 + P(Not White Car)  = 1

Subtract 0.08 from both sides of the equation

So, we have

P(Not White Car)  = 1 - 0.08

Evaluate the difference

P(Not White Car)  = 0.92

Hence, the probability that the next car will not be a white car is 0.92

The first five terms of the given sequence are 4, 1, 6, 13, 22

We can solve this problem by following a few steps.

The formula to find the next four terms is, a =  (n)²- 3, (n ≥2) as per the question.

Where n is the sequence of the number ( n = 2, 3, 4, 5, 6, etc. )

So, for the 2nd term A₂ = 2² - 3 = 4 - 3 = 1  [As n = 2 for the second term ]

Similarly, for the 3rd term A₃ = 3² - 3 = 9 - 3 = 6  [ As n = 3 for the third term ] ,

for the 4th term A₄ = 4² - 3 = 16 - 3 = 13  [ As n = 4 for the second term ] ,

for the 5th term A₂ = 5² - 3 = 25 - 3 = 22  [As n = 5 for the second term ]

The equation as a function of x is y = 9280 -20x

Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right are shown to be equal in reference to one another. LHS = RHS (left hand side = right hand side) appears in all mathematical equations. You can solve equations to determine an unknown variable's value, which corresponds to an unknown quantity. It is not an equation if there is no "equal to" sign in the statement. It shall be taken into account as an expression.

The equation is =[tex]\frac{1}{16}x + \frac{1}{320}y - 29= 0[/tex]

Now rearranging the function we write

[tex]\frac{y}{320}= 29 -\frac{x}{16}[/tex]

An equation of the line containing the given point and parallel to the given line is y = 2x - 19.

In Mathematics, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts. This ultimately implies that, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m is the slope.

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

Given the following equation:

2x - 56 = 3     ⇒ m₁ = 2

Therefore, m₁ = m₂ = 2.

At point (8, -3), we have:

y - y₁ = m(x - x₁)

y - (-3) = 2(x - 8)

y + 3 = 2(x - 8)

y + 3 = 2x - 16

y = 2x - 16 - 3

Jack's percentage decrease on his measurement of painting by 18%.

What is meant by percentage change?

Measures of percent change include percent increase and percent decease, which indicate how much an element of a variable changes in terms of intensity, size, extent, or value.

Given that,

Jack's measurement for his room =  5 ft (taking this as old value)

Actual measurement for Jack's room = 4.1 ft (taking this as new value)

Using formula for Percent change =  [tex]\frac{new - old}{old}[/tex]  × 100% =  [tex]\frac{4.1 - 5}{5}[/tex] × 100%

                                                       =  [tex]\frac{-0.9}{5}[/tex] × 100% = -0.18 × 100%

                                                       = -18%

Here, minus sign represents the decrease in percentage.

The price per ticket, excluding the convenience charge, is  $65.

the rush delivery is given as $15.

The total cost of the tickets is said to be put at $352.50

Then the value that we would have for the the 5 tickets wpould be 352.50 - 15 = $337.50.

There is the convenience charge of $2.50 per ticket. This charge is excluded from the convenience charge that is to be paid.

Hence you would have to make the payment of

337.50 - 5*2.50
