5 0

Let the event A=\{ Sophomore \}, B=\{ Boy \}

The the probability of the events

P(A \cap B)=\frac{5}{12+18} =\frac{1}{6}

P( B)=\frac{12}{12+18} =\frac{2}{5}

The conditional probability

P(Sophomore|Boy)=P(A|B)=\frac{P(A \cap B)}{P(B)} =\frac{1/6}{2/5} =\frac{5}{12}

Nour drove from the Dead Sea up to Amman and her altitude was 409 meters below sea level. When she arrived in Amman 2 hours late
kozerog [31]

Answer:

y=  704.5x - 409

Step-by-step explanation:

Complete question is : . Complete the equation for the relationship between the altitude and number of hours.

SOLUTION

By plotting altitude on y-axis and time or duration of travel on x-axis of the graph, we will have the the location of Nour at t = 0 will be represented by (0, -409)

when t = 2 hours location points will be  at (2, 1000).

As you know, at a constant rate her altitude is increasing , we will have a linear graph with equation y = mx + b --> eq(1)

Slope of the line is given by:

m= (y-y') / (x-x') => (1000+409)/(2-0)

m= 704.5

y-intercept 'b' is -409

Therefore, the eq(1) will become

(1)=> y=  704.5x - 409

Where, 'y' represents Nour's altitude(in meters) relative to sea level after 'x' hours

Determine whether or not the lines are parallel based on the
Vitek1552 [10]

Answer:

answer

Step-by-step explanation:

To see whether or not two lines are parallel, we must compare their slopes. Two lines are parallel if and only if their slopes are equal. The line 2x – 3y = 4 is in standard form. In general, a line in the form Ax + By = C has a slope of –A/B; therefore, the slope of line q must be –2/–3 = 2/3.
