Answer:
Sabrina necesito 8 horas para llegar a su casa mientras que Diana necesito solo 3.4 horas.
Step-by-step explanation:
debemos resolver la siguientes equaciones:
A + B = 11.4
65A + 50B = 690
donde:
A = tiempo que le toma a Sabrina llegar a su casa
B = tiempo que le toma a Diana llegar a su casa
A = 11.4 - B
65 (11.4 - B) + 50B = 690
741 - 65B + 50B = 690
741 - 690 = 65B - 50B
51 = 15B
B = 51 / 15 = 3.4 horas
A = 11.4 - 3.4 = 8 horas
The combination of c, d and p are cdp, cpd, dcp, dpc, pcd, pdc.
a. The probability for each one of the combination is 1/6
b. Combination that has c ranked first is 2
Probability of c is ranked first will be 2/6.
c. Sequence that c is ranked first and d is ranked last is only one that is cpd.So the probability is 1/6
A fraction is bigger or smaller depending on the numerator and denominator.
For example, 1/2 is larger than 1/4 because a half is larger than a quarter. This means that the larger the number underneath, the smaller the number.
But, this can change if the numerator (the number on top) is different than one.
For example, 3/4 is greater than 1/2 because three quarters is more than a half. (two quarters is equal to a half)
Answer:
<em>The point lies barely outside of the circle</em>
Step-by-step explanation:
<u>Equation of a Circle</u>
Given its center (h,k) and radius r, the equation of a circle is given by
The circle given in the question is centered at (7,8) and has a radius of 6, thus its equation is
To find out if a point (a,b) is outside or inside the circle area, the following conditions apply.
if 
then the point lies outside of the circle area
if 
then the point lies inside of the circle area
Let's use the point as given (6,2)
Thus the point lies barely outside of the circle
The 3 values would be 9 , 10 and 11.
because:
48<6(9)
48<54
48<6(10)
48<60
48<6(11)
48<66
