A box of chocolates contains 24 chocolates. Ten of the chocolates have cherry centers. All chocolates appear the same.
Two chocolates are selected. Find the probability of each of the following. (Round your answers to four decimal places.)
(a) both have cherry centers
(b) one has a cherry center and one does not
Answers
The probability of selecting chocolate such that:
(a) both have cherry centers: 0.1630
(b) one has a cherry center and one does not: 0.507
In this question, we have been given a box of chocolates contains 24 chocolates.
n(S) = 24
Ten of the chocolates with cherry centers.
n(A) = 10
So, the number of chocolates with no cherry centers are:
n(B) = 14
We need to find the probability of selecting chocolate such that
(a) both have cherry centers
P = (10/24)(9/23)
P = 90/552
P = 15/92
P = 0.1630
(b) one has a cherry center and one does not
P = 2*(10/24)(14/23)
P = 0.507
Therefore, the probability of selecting chocolate:
(a) both have cherry centers
P = 0.1630
(b) one has a cherry center and one does not
P = 0.507

South Pole Edition
Your Outdoor Adventures class is providing guidance to a group that is on an expedition to the South Pole. There are 5 people on the expedition.
Due to the extreme climate and conditions, each person in the group needs to consume 6000 calories per day. The table shows the three foods that will make up their total daily calories, along with the number of calories per unit and the daily needs by percentage.
(chart is in the photo i provided)
The map shows the current location of the group, as well as the location of the South Pole and the base camp. Each unit on the grid represents 5 miles. In the question that follow, you will determine whether the group has enough food to reach the South Pole and return to base camp.
Question:
The group thought there was enough food for all 5 group members to complete the trip, with each person getting the required 6000 calories per day. They discover that 2 of the crates they brought are missing.
Each crate contains
•80 biscuits
•50 packages of pemmican
•10 packages of butter and cocoa
Use the map, create a plan for the rest of the trip that includes taking as many group members as possible to the South Pole, while sending the rest of the group members directly back to base camp. Remember that each person must have 6000 calories of food per day until he or she gets back to base camp.
Answers
The group does not have enough food to complete the trip with all five members. By sacrificing one member's trip to the South Pole and carefully rationing the food, the group can ensure that each person has enough food to complete the trip safely.
How did we arrive at this assertion?According to the given chart, calculate that each crate contains a total of 48000 calories. Therefore, two missing crates result in a total loss of 96000 calories (48000 x 2).
Determining whether the group has enough food to reach the South Pole and return to base camp, calculate the total number of calories required for the entire trip. Supposing a round trip of 10 days to the South Pole and back, the total number of calories required would be:
Total Calories = (6000 calories/person x 5 people x 10 days) x 2 (round trip)
Total Calories = 600,000 calories
To cover for the lost calories, the group would need to sacrifice one member's trip to the South Pole and send them directly back to base camp. This would leave four members to continue to the South Pole, where they would have to ration their food carefully to make sure they have enough for the entire trip.
Below is a plan to ensure enough food:
Day 1-2:
All five members travel together to position (2,1) and set up camp.Each member would consume 6000 calories per day.Total calories consumed: 5 people x 6000 calories x 2 days = 60,000 caloriesDay 3-5:
Four members (let's call them A, B, C, and D) continue to the South Pole while one member (let's call them E) returns to base camp.E would need 6000 calories per day to return to base camp.Total calories consumed by E: 1 person x 6000 calories x 3 days = 18,000 caloriesA, B, C, and D would have to consume 15000 calories per day (60000 calories ÷ 4 people ÷ 2 days) to make up for the lost calories.Total calories consumed by A, B, C, and D: 4 people x 15000 calories x 3 days = 180,000 caloriesDay 6-7:
A, B, C, and D reach the South Pole and set up camp.They would need 6000 calories per day for 2 days.Total calories consumed: 4 people x 6000 calories x 2 days = 48,000 caloriesDay 8-10:
A, B, C, and D return to position (2,1) and pick up E on the way.They would need 6000 calories per day for 3 days.Total calories consumed: 5 people x 6000 calories x 3 days = 90,000 caloriesAdd up all the total calories consumed:
60,000 + 18,000 + 180,000 + 48,000 + 90,000 = 396,000 calories
This is less than the total calories required, which was 600,000 calories. Therefore, the group does not have enough food to complete the trip with all five members. By sacrificing one member's trip to the South Pole and carefully rationing the food, the group can ensure that each person has enough food to complete the trip safely.

Answers
Answer:
$638.42
Step-by-step explanation:
First, we need to calculate the sale price of the tablet computer after the 14% discount is applied. To do this, we can multiply the original price by 0.86 (1 - 0.14), which gives:
Sale price = $707 x 0.86 = $608.02
Next, we need to add the sales tax to the sale price. To do this, we can multiply the sale price by 0.05 (5%), which gives:
Sales tax = $608.02 x 0.05 = $30.40
Finally, we can find the total cost of the tablet computer by adding the sale price and the sales tax, which gives:
Total cost = $608.02 + $30.40 = $638.42
Therefore, the total cost of the tablet computer with the discount and sales tax included is $638.42.

What is defined as linear equation on two variables?A linear function does have a positive relationship, so increasing one variable (input variable) causes a rise in the second variable (output variable), implying that the variables have always been directly proportional. As a result, the graph of such a linear function is a straight line with a constant slope.Correspondingly, a linear equation is a first-order algebraic equation with two variables and terms with exponents of one.A linear equation in 2 variables [x and y] is any equation with the form:
ax + by = c and at least one of a or b being non-zero.
This is known as the equation's General Form.
For the given question;
The water hold by bucket = c litres.
The water hold by jar = d litres.
Thus, the water hold by both bucket and jar is is linear equation with two variable c and d.
Total water = c + d
By, varying any value the total amount of the water will also get change.
Thus, total water hold by jar and bucket is (c + d) litres.

Answers
Answer:
A
Step-by-step explanation:
The equation of line is y= -4x -23
What is slope- intercept form?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
The slope of the line is the ratio of the rise to the run, or the rise divided by the run, therefore the change in y coordinate with regard to the change in x coordinate may be expressed as follows. In the coordinate plane, it describes the slope of the line.
Given:
We can take the coordinates from the given graph as (0, 3) and (2, -5)
Now, the slope = (-5 - 3)/ (2 - 0)
slope= -8/ 2
slope= -4
Now, using the point- slope form
(y - \(y_1\)) = m(x - \(x_1\))
(y- (-3))= -4( x- (-5))
y+3 = -4(x+5)
y+ 3= -4x - 20
y= -4x -23
Hence, the equation of line is y= -4x -23.

An online furniture store sells chairs for $100 each and tables for $550 each. Every day, the store can ship at most 25 pieces of furniture and must sell no less than $7000 worth of chairs and tables. If 9 chairs were sold, determine all possible values for the number of tables that the store must sell in order to meet the requirements. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.
Answers
Answer:
(10, 11, 12, 13, 14, 15, 16)
Step-by-step explanation:
The minimum number of tables that the store has to sell in order to meet the requirements is given by:
\((25-t)*100+t*550=7,000\\(550-100)t=7,000-2,500\\t = 10\ tables\)
The company must sell at least 10 tables.
Since the company already sold 9 chairs, and they can ship at most 25 items, they can sell at most 16 tables. Every integer number between the minimum and maximum is also possible:

Store A sells a watch for $50 and offers a 5% discount Store B sells the same watch for $60 and offers a 20% discount. From which store should you buy your
watch and why? Help please!!
Answers
Answer:
You should buy the watch from Store A because it's cheaper
Step-by-step explanation:
Store A sells a watch for $50 with a 5% discount.
Let's calculate the sale price. The 5% discount is
5/100*$50 = $2.50
The sale price is $50 - $2.50 = $47.50
Now for Store B. The price of the watch was $60 with a 20% discount.
Calculate 20% of $60:
20/100*$60 = $12
The sale price is $60 - $12 = $48
Thus, you should buy the watch from Store A because it's cheaper
