An engineering firm is hired to determine if certain waterways in Virginia are safe for fishing. Samples

Natalija [7]

Answer:

(a) S = {FFF, FFN, FNN, FNF, NNN, NNF, NFF, NFN}

(b) S(E) = {FFF, FFN, FNF, NFF}

(c) Second river is safe for fishing

Step-by-step explanation:

F = safe to fish

N = not safe to fish

number of rivers sampled = 3

(a) All of the possible outcomes obtained from the samples are listed in the sample space bellow:

S = {FFF, FFN, FNN, FNF, NNN, NNF, NFF, NFN}

(b) If at least two rivers are safe, the sample space for E is all of the events with two or three safe rivers:

S(E) = {FFF, FFN, FNF, NFF}

(c) In the set {FFF, NFF, FFN, NFN}, the second lake sample is safe to fish in all of the elements. The event is: second river is safe for fishing.

Riley and Rhoda plan to buy 2 bags of dog of food and a dog collar (x). Each bag of dog food costs $7 and the dog collar costs $

Sergio [31]

Let:

T = Total money they have

Dc = Dog collar

x = Number of bags of food

$\begin{gathered} 2x+Dc\le T \\ 2x+4.5\le30 \end{gathered}$

Let's solve the inequality:

$\begin{gathered} 2x+4.5\le30 \\ \text{subtract 4.5 from both sides:} \\ 2x+4.5-4.5\le30-4.5 \\ 2x\le25.5 \\ x\le\frac{25.5}{2} \\ x=12.75\approx12 \end{gathered}$

This means that they can buy 12 bags of food at most.

Since they plan to buy 2 bags of food:

$\begin{gathered} 2(7)+4.5\le30 \\ 14+4.5\le30 \\ 18.5\le30 \end{gathered}$

This means they can do it and have $ 11.5 to spare

The coordinates of the endpoints of ST are (-2,3) and (3, y) respectively supposethe distance between s and t us 13 units.What v

igor_vitrenko [27]

Answer:

The values of y would be -9 and 15

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$d=13\ units$

S(-2,3) and T(3,y)

substitute the given values in the formula and solve for y

$13=\sqrt{(y-3)^{2}+(3+2)^{2}}$

$13=\sqrt{(y-3)^{2}+25}$

squared both sides

$169=(y-3)^{2}+25$

$(y-3)^{2}=169-25$

$(y-3)^{2}=144$

take square root both sides

$y-3=(+/-)12$

$y=3(+/-)12$

$y=3(+)12=15$

$y=3(-)12=-9$

therefore

The values of y would be -9 and 15
