The equation d=rt is used to calculate distance, rate, or time, where dd is the distance (in meters), r is the rate (in meters p

er minute), and tt is the time (in minutes). Consider the statements below that describe the walking rates for three people. Graph the equation that represents the rate of the fastest person. Tomas walks 1200 meters in 8 minutes. Becky walks for 10 minutes and goes 1400 meters. Derrick walks at a rate of 145 meters per minute.

We know derrick walks 145 m/min to get the other we simply divide how far they went in how much time
Tomas: 1200/8= 150 m/min
Becky: 1400/10= 140m/min
therefore Tomas is the fastest walker so we will write the equation based on his speed
y = 150x
you should start at the origin (0,0) and got up 150 meters for and over 1 for every minute they run!

According to the National Telecommunication and Information Administration, 56.5% of U.S. households owned a computer in 2001. W
Liono4ka [1.6K]

Answer:

Step-by-step explanation:

Assuming a binomial distribution for the number of U.S. households that owned a computer in 2001. The formula for binomial distribution is expressed as

P(X = r) = nCr × q^(n - r) × p^r

Where

p = probability of success

q = probability of failure

n = number of sample

From the information given,

p = 56.5% = 56.5/190 = 0.565

q = 1 - p = 1 - 0.565 = 0.435

n = 3

We want to determine P(x greater than or equal to 1). This is also expressed as

1 - P(x lesser than or equal to 1)

P(x lesser than or equal to 1) = P(x = 0) + P(x =1)

P(x = 0) = 3C0 × 0.435^(3 - 0) × 0.565^0 = 0.082

P(x = 1) = 3C1 × 0.435^(3 - 1) × 0.565^1 = 0.32

P(x greater than or equal to 1) = 0.082 + 0.32 = 0.402

GREYUIT [131]
<h2>Answer:</h2>

29%

<h2>Explanations:</h2>

Probability is the likelihood or chance that ab event will occur. Mathematically;

Probability = Expected/Total

From the given table, the total number of male student is the total outcome as shown:

Total outcome = 4 +6+ 2 + 2

Total outcome = 14

If a male freshmen is selected at random, the expected outcome will be 4.

Determine the probability

\begin{gathered} Pr(Freshman\text{ \mid Male})=\frac{Male\text{ freshmen}}{Total\text{ male studnt}} \\ Pr(Freshman\text{ \mid Male})=\frac{4}{14} \\ Pr(Freshman\text{ \mid Male})=0.2857\times100 \\ Pr(Freshman\text{ \mid Male})\approx29\% \\  \end{gathered}

Hence the probability that the male student is freshman is approximately 29%
