Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

<em>See attachment for complete question</em>

Given

Malcom's Family:

d = 65t

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

t = 1; d = 50

t = 2; d = 100

First, we determine the slope, m:

m = \frac{d_2 - d_1}{t_2 - t_1}

m = \frac{100 - 50}{2- 1}

m = \frac{50}{1}

m = 50

Next, we determine equation for Theo's family using:

d - d_1 = m(t - t_1)

d - 50 =50(t - 1)

d - 50 =50t - 50

Add 50 to both sides

d - 50 +50=50t - 50 + 50

d =50t

So, we have the following:

d = 65t --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

d =50t --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

Rate = 65t - 50t

Rate = 15t

<em>Which implies that Malcom's family travel 15 miles per hour faster than Theo's</em>

Two faces of a six-sided die are painted red, two are painted blue, and two are painted yellow. The die is rolled three times, a
Keith_Richards [23]

Answer:

(a) 4/9

(b) 19/27

Step-by-step explanation:

The probability of each die turning up red or not turning red are:

P(R) =\frac{2}{6}= \frac{1}{3}\\P(O) =\frac{4}{6}= \frac{2}{3}

(a). Exactly one face up is red.

The odds of only the first die being red are:

P(A=R) =\frac{1}{3} *\frac{2}{3}* \frac{2}{3} \\P(1=R) =\frac{4}{27}

The same odds are valid for only the second or only the third die being red. Therefore, the probability that exactly one die turns up red is:

P(R=1) = 3*\frac{4}{27}\\P(R=1) = \frac{4}{9}

(b). At least one face up is red.

The probability that at least one die turns up red is the sum of the probabilities of exactly one (found in the previous item), two or all dice turning up red.

Following the same logic as in the previous item, the probability that exactly two dice turn up red is:

P(R=2) = 3*(\frac{1}{3}*\frac{1}{3}*\frac{2}{3})\\P(R=2) = \frac{2}{9}

The probability that all die turn up red is:

P(R=3) = \frac{1}{3}*\frac{1}{3}*\frac{1}{3}\\P(R=3)=\frac{1}{27}

Thus, the probability that at least one die turns up red is:

P= P(R=1)+P(R=2)+P(R=3) = \frac{4}{9}+\frac{2}{9}+\frac{1}{27}\\P=\frac{19}{27}
