Answer:

0.32

Step-by-step explanation:

P(B|A) = P(A∩B) / P(A)

0.25 = 0.08 / P(A)

P(A) = 0.32

Answer:

The likelihood that the randomly chosen student is a student athlete equals 0.32.

Step-by-step explanation:

Provided: A lone student will be selected randomly from a high school. Designate A as the event where the selected individual is a student athlete, and B as the event where the selected student drives to school.

Given values are P(A∩B)=0.08 and P(B|A)=0.25.

Need to determine: The probability of the selected student being a student athlete?

Solution:

A random selection will be made from high school students, and we inquire whether this student will qualify as a student athlete i.e. P(A)

Utilizing conditional probability,

P(B|A) =\frac{P(A\cap B)}{P(A)}

0.25= \frac{0.08}{P(A)}

P(A)= \frac{0.08}{0.25}

P(A)=0.32

Consequently, the likelihood that the selected student is an athlete equals 0.32.

Answers:

The vertical asymptote is located at x = 0

The horizontal asymptote is identified as y = 0

The domain encompasses all real nonzero values

The range includes all nonzero real values

EXPLANATIONS

Given the function f(x) = c/x

c represents a non-zero real number

To find the vertical asymptote, we equate the denominator to 0

f(x)=c/x

The denominator is x

Setting x = 0

To establish the horizontal asymptote, we must compare the polynomial degrees in the numerator and denominator.

The numerator contains a polynomial of degree zero

While the denominator has a polynomial of degree one.

<span> Since the numerator's polynomial degree is less than that of the denominator, the horizontal asymptote is at y=0.</span>

Because the vertical asymptote is x = 0, the domain consists of all real numbers except x = 0

With the horizontal asymptote being y = 0, the range is all real numbers excluding y = 0

A 2.2 GB game is being downloaded onto your laptop. When you have downloaded half a gigabyte, you notice that your computer has
zzz [12365]

Answer:

0.01m +\frac{1}{2} \geq 2.2

Step-by-step explanation:

Let m denote the number of minutes required to download the entire game.

The computer downloads at a speed of 0.01 GB per minute, and since half a gigabyte has already been downloaded, we can express this as 0.01*m + 0.5 equaling 2.2, as the game's total size is 2.2 GB.

We will determine the minimum number of minutes necessary to completely download the game.

0.01m +\frac{1}{2} \geq 2.2

0.01m +0.5\geq 2.2

0.01m \geq 2.2-0.5

0.01m \geq 1.7

m\geq \frac{1.5}{0.01}

Thus, 0.01m +\frac{1}{2} \geq 2.2 represents our sought inequality.

MATHEMATICS: A boy leaves home at 09:15 hours and arrives at 10:05 hours. If he travels nonstop at an average speed of 6kmh ,wha
PIT_PIT [12445]
5 km. To determine the distance, we apply the speed formula that correlates distance with time: v = d / t. Thus, when rearranging for distance, we get: d = v * t. The speed is noted as 6 km/h, but we need to find the time taken - given he departs at 9:15 and returns at 10:05, the total time is 50 minutes. Converting this duration into hours gives us 50 min * 1 h / 60 min = 0.833 h. Hence, the duration for the journey to school is established as 0.833 hours. Substituting into our equation provides: d = 6 * 0.8333, yielding a distance of 5 km between the school and home.

Line RS intersects triangle BCD at two points and is parallel to segment DC. Triangle B C D is cut by line R S. Line R S goes th
Zina [12379]

Answer:

The correct statements are;

1) ΔBCD is similar to ΔBSR

2) BR/RD = BS/SC

3) (BR)(SC) = (RD)(BS)

Step-by-step explanation:

1) Since RS is parallel to DC, we conclude that;

∠BDC = ∠BRS (Angles formed on the same side of the transversal)

Furthermore;

∠BCD = ∠BSR (Angles formed on the same side of the transversal)

∠CBD = ∠CBD (Reflexive property)

Thus;

ΔBCD ~ ΔBSR by the Angle-Angle-Angle (AAA) similarity criterion.

2) Given that  ΔBCD ~ ΔBSR, we obtain;

BC/BS = BD/BR → (BS + SC)/BS = (BR + RD)/BR = 1 + SC/BS = RD/BR + 1

1 + SC/BS = 1 + RD/BR thus, SC/BS = 1 + BR/RD - 1

SC/BS = RD/BR

By inverting both sides we find;

BR/RD = BS/SC

3) From BR/RD = BS/SC, we apply cross multiplication;

BR/RD = BS/SC leads to;

BR × SC = RD × BS → (BR)(SC) = (RD)(BS).
