1.0000 percent is the probability that all 12 flights will arrive on time.

So, the problem meets all requirements for a binomial experiment, written as:

[tex]P(X=x)\left(\begin{array}{l}n \\x\end{array}\right) p^x(1-p)^{n-x}[/tex]

Now, p=0.85 and n=14, the probability that precisely 14 people arrived on time are calculated as follows:

[tex]\begin{aligned}&P(X \geq 1)=1-P(X=0) \\&=1-\left(\begin{array}{c}12 \\0\end{array}\right) 0.85^0(1-0.85)^{12} \\&=1-1.297 \times 10^{-10} \\&=1.0000\end{aligned}[/tex]

Therefore, 1.0000 percent is the probability that all 12 flights will arrive on time.

Answer:

1100

Step-by-step explanation:

783 rounded to the nearest hundred is 800

329 rounded to the nearest hundred is 300

800+300=1100

The estimation of 783 + 329 = 1100.

Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. The supplied number is said to be rounded up when the rounded number is increased, and it is said to be rounded down when the rounded number is dropped.

Given:

783 + 329

Now rounding off nearest hundred

783 rounded off to 800

and, 329 rounded off to 300.

So, 800+ 300 = 1100

Hence, the estimation is 1100.

Answer:  8x + 3, where x is the number of hours

The unit rate is 10 minutes per meters.

What is rate of time?

Time is in units of seconds, minutes, hours, or years. Rate is distance per time, so its units could be mph, meters per second, or inches per year.

rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute.

Given,

she fills 4/5 meters in 8 minutes.

let x be the time she fills minutes per liter.

4/5 meters ⇔ 8 minutes

1 meter ⇔ x minutes

Cross multiplying

4/5*x = 1*8

x = 5*8/4

x = 10 minutes

The unit rate is 10 minutes.

The first skater has a 40 meter d and is traveling at a rate of 12 meters second, second skater is traveling rate of 14 meters per second. it will take 20 seconds for second skater to pass the first skater.

Time is continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in conscious experience. Time is often referred to as fourth dimension, along with three spatial dimensions.

Time has long been an important subject of study in religion, philosophy, and science, but defining it in manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and performing arts all incorporate some notion of time into their respective measuring systems.

The slope of the linear equation is 0, so this is a horizontal line.

A linear equation is of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

Particularly, if a a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Here we have the points  (7, -4) and (11,−4), then the slope is:

A round plane figure whose boundary ( circumference) consists of the points equidistant from a fixed point (the center). In the above question Pedro was wrong.

All the points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in plane draws to keep its distance from a specific point constant.

The tactic Pedro frequently used is ineffective since applying strict transformation to one figure and then onto another will only demonstrate whether the figures are congruent, not whether they are comparable.

Keep in mind that resemblance, as opposed to congruence, is about the proportionality between the dimensions of those figures. Therefore, when we overlay the figures, they won't match.

Pedro should divide each set of matching coordinates to demonstrate similarity; if all divisions provide the same outcome, the figures are said to be comparable.

Therefore, Pedro was not wrong.

Matching the trigonometry formula to its ratio, we get

4/3 → tan A

4/5 → sin A

3/5 → cos A

From the question, we are to match the given trigonometry formulas to their correct ratios.

From SOH CAH TOA, we have that

sin (angle) = opposite / hypotenuse

cos (angle) = adjacent / hypotenuse

tan (angle) = opposite / adjacent

Considering angle A,

Opposite = 16

Adjacent = 12

Hypotenuse = 20

Thus,

tan A = 16 / 12 = 4 / 3

sin A = 16 / 20 = 4 / 5

cos A = 12 /20 = 3 / 5

Answer:

y = [tex]\frac{1}{4}[/tex] x - 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given m = [tex]\frac{1}{4}[/tex] , then

y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

to find c substitute (- 8, - 8 ) into the partial equation

- 8 = - 2 + c ⇒ c = - 8 + 2 = - 6

Answer:

mperpendicular = −2/5

Step-by-step explanation:

The correct answer is 20%

We know,

1 m = 100 cm

thus 1.5 m will be 150 cm (1.5 x 100 = 150cm)

now, to find 30 cm as a percentage :

(30/150) x 100

=20 %

Thus, 30cm 1.5 can be expressed, as  20%.

What do you understand by percentage?

percentage- "a relative value indicating hundredth parts of any quantity." Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
