A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random.
DerKrebs [107]

corrected question:A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random. For each of the following, find the probability that: a) both marbles are blue b) both marbles are the same color  c)the marbles are different in color

Answer:

Step-by-step explanation:

<u><em>The probability was done with replacement.</em></u>

Probaility of an event happening=\frac{number of required outcomes}{number of possible outcomes}

number of blue marbles= 2

number of green marbles=5

total number of marbles=7

(a) probability that both marbles are blue = pr(first is blue)*pr(second is blue)

                                  =\frac{2}{7}*\frac{2}{7}

                                   =\frac{4}{49}

(b)probability that both marbles are the same color =pr(first is blue)*pr(second is blue) + Pr(first is green)*Pr(second is green)

   =\frac{4}{49} + \frac{5}{7}*\frac{5}{7}

   =\frac{4}{49} + \frac{25}{49}

 =\frac{29}{49}

(c)Probability that the marbles are different in colors=pr(first is blue)*pr(second is green) + Pr(first is green)*Pr(second is blue)

  =\frac{2}{7}*\frac{5}{7}+ \frac{5}{7}*\frac{2}{7}

           =\frac{10}{49}+\frac{10}{49}

      =\frac{20}{49}

Find the slope of the line that passes through the points (­-8, ­-3) and (2, 3)
kherson [118]

Answer:

The slope is 3/5.

Step-by-step explanation:

Slope formula:

\displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{rise}{run}

\displaystyle \frac{3-(-3)}{2-(-8)}=\frac{6}{10}=\frac{6\div2}{10\div2}=\frac{3}{5}

Therefore, the slope is 3/5, and the correct answer is 3/5.

Alexandra is creating a food budget. Each day, her goal is to spend no more than $2 for breakfast, $8 for lunch, and $8 for dinn
Paladinen [302]

Answer:

Alexander estimate is not a good estimate

Step-by-step explanation:

Breakfast = $2

Lunch = $8

Dinner = $8

Total amount spent on food each month = (cost of breakfast × number of days) + (cost of lunch × number of days) + (cost of dinner × number of days)

= ($2 × 30) + ($8 × 30) + ($8 × 30)

= $(60 + 240 + 240)

= $540

Total cost estimate of food in a month = $540

Alexander estimate is not a good estimate
