A data scientist tried to many cups of coffee she drink every day at work over the course of the year. She used the data to build a probability distribution where the random variable C represents the number of cups of coffee she drank on a given day. Find the missing probability for someone who has two or more cups of coffee.

A Data Scientist Tried To Many Cups Of Coffee She Drink Every Day At Work Over The Course Of The Year.

Answers

Answer 1
Final answer:

To find the missing probability for consuming two or more cups of coffee in the data scientist's distribution, subtract the sum of the probabilities of all other events from 1, ensuring that all probabilities in the distribution meet the criteria of summing to 1 and each being between 0 and 1.

Explanation:

The question pertains to constructing a probability distribution for a data scientist's daily coffee consumption at work. The random variable C stands for the number of cups of coffee she drinks on a given day. To calculate the missing probability for someone who has two or more cups of coffee, one must know the individual probabilities of all other events (0, 1, 2, etc., cups of coffee). The sum of all these probabilities must equal 1, since that represents the certain event that some outcome in the distribution will occur. To find the missing probability, one would subtract the sum of the probabilities for 0 and 1 cups (if those are the only other events) from 1.

For example, if the probability of drinking 0 cups is 0.1 and the probability of 1 cup is 0.3, then the probability of drinking two or more cups would be 1 - (0.1 + 0.3) = 0.6. Important characteristics of a discrete probability distribution include that the sum of probabilities is 1 and that each individual probability is between 0 and 1, inclusive.

Step-by-step explanation:

The temperature in a greenhouse should be 65 degrees or higher. One​ morning, the heater stopped working. The temperature dropped 6 degrees before someone fixed the heater. The temperature was still at least 65 degrees when the heater started working again. How can you best describe the temperature in the greenhouse before the heater stopped​ working?

Answers

Final answer:

The temperature in the greenhouse before the heater stopped working was at least 71 degrees Fahrenheit, based on the information that the temperature dropped 6 degrees but remained at least 65 degrees.

Explanation:

As the temperature dropped 6 degrees and was still at least 65 degrees when the heater was fixed, we can set up a simple inequality to represent this situation:

Let T represent the temperature before the heater stopped working. After the heater stopped working and the temperature dropped by 6 degrees, the new temperature would be T - 6. According to the provided information, this new temperature was still at least 65 degrees, which gives us the inequality:

T − 6 ≥ 65

Adding 6 to both sides of the inequality, we find:

T ≥ 71

This means that the temperature in the greenhouse before the heater stopped working was at least 71 degrees.  

Fernando bought a jacket for $185 and sold it for 1 1/2 times what he paid. Marisol spent 1/5 as much as Fernando on the same jacket but sold it for 1/2 as much as Fernando did. How much money did Marisol make? Explain your thinking using a diagram

Answers

We have been given that Fernando bought a jacket for $185 and sold it for 1 1/2 times what he paid.

Let us find selling price of jacket as:

[tex]\text{Selling price of Fernando's jacket}=\$185\times 1\frac{1}{2}[/tex]

[tex]\text{Selling price of Fernando's jacket}=\$185\times \frac{3}{2}[/tex]

[tex]\text{Selling price of Fernando's jacket}=\$277.5[/tex]

We have been given that Marisol spent 1/5 as much as Fernando on the same jacket.

[tex]\text{Cost of Marisol's jacket}=\$185\times \frac{1}{5}[/tex]

[tex]\text{Cost of Marisol's jacket}=\$37[/tex]

We are also told that Marisol sold the jacket for 1/2 as much as Fernando did.

[tex]\text{Selling price of Marisol's jacket}=\frac{\$277.5}{2}[/tex]

[tex]\text{Selling price of Marisol's jacket}=\$138.75[/tex]

The amount of money earned by Marisol would be selling price of jacket minus cost.

[tex]\text{Amount of money earned by Marisol}=\$138.75-\$37[/tex]

[tex]\text{Amount of money earned by Marisol}=\$101.75[/tex]

Therefore, Marisol made $101.75.

The measure of XYZ is 45. The length of radius YZ is 6 inches. What is the area of sector XYZ?


(Use 3.14 for I.)

Answers

Answer:

area of a sector = 14.13 yards²

Step-by-step explanation:

XYZ is a sector of a circle. The radius YZ is 6 inches .The angle of the sector is given as 45°. The area of the sector can be solved as follows.

area of a sector = ∅/360 × πr²

where

r = radius

∅ = center angle

r = 6 inches

∅ = 45°

area of a sector = 45/360 × 3.14 × 6²

area of a sector = 45/360 × 3.14 × 36

area of a sector = 45/360 × 113.04

area of sector = 1/8 × 113.04

area of a sector = 14.13 yards²

a triangular section of a farm is enclosed by fences that are 2 meters, 6 meters, and 7 meters long, estimate the area of the section

Answers

Final answer:

To estimate the area of a triangular section with sides 2 meters, 6 meters, and 7 meters, you can use Heron's formula. The semi-perimeter is 7.5 meters. The estimated area of the triangle is approximately 5.56 square meters.

Explanation:

To estimate the area of a triangular section of a farm enclosed by fences that are 2 meters, 6 meters, and 7 meters long, we can use Heron's formula. First, we calculate the semi-perimeter (s) of the triangle:

s = (a + b + c) / 2s = (2 + 6 + 7) / 2s = 15 / 2s = 7.5 meters

Now, we use Heron's formula to find the area (A):

A = √(s(s-a)(s-b)(s-c))A = √(7.5(7.5 - 2)(7.5 - 6)(7.5 - 7))A = √(7.5 * 5.5 * 1.5 * 0.5)A = √(30.9375)A ≈ 5.56 square meters

Therefore, the estimated area of the triangular section of the farm is approximately 5.56 square meters.

This problem is solved using concept of LCM.

LCM is the least number which is the common multiple of given set of different number.

To find the LCM  we method of prime factors, the steps are given below

get all the all the prime factor of the given set of numberselect all the prime factors   as many times they occur in given set of numbermultiply together the numbers selected together to get LCM

________________________________________________

Given

frequency of visiting swimming pool by Shwetha = once in 12 days

factors of 12 = 2 * 2 * 3

frequency of visiting swimming pool by Vinnie = once in 4 days

factors of 2 = 2 * 2

frequency of visiting swimming pool by Olga = once in 10 days

factors of 10 = 2 * 5

minimum no of days after which they will be visiting together will be least common multiple of number of days after which they visit swimming pool individually.

Selecting the prime numbers with their highest occurrence

we have 2, 2, 3 ,5

multiplying them together we have

2 * 2 * 3* 5 = 60

therefore 60 is the LCM of 12, 4, 10

it means that Shwetha, Vinnie and Olga will visit swimming pool together once in 60 days

It is given that they visited on Monday  and now they will visit after 60 days again.

since in one week there are seven days, every eighth day will be monday

so we divide 60 days by 7 to see how many cycles of monday has passed.

60/7 = 8  4/7

It suggest that 8 weeks has passed and they will meet on 4 days after Monday  which will be Friday.

Thus they will meet meet at the swimming pool again in 60 days.

It will be Friday.

In an assembly line, 56 out of 60 randomly selected parts have no faults. Predict the number of parts that will have no faults in a similar batch of 12,000 parts.

Answers

We have been given that in an assembly line, 56 out of 60 randomly selected parts have no faults. We are asked to predict the number of parts that will have no faults in a similar batch of 12,000 parts.

We will use proportions to solve our given problem.

[tex]\frac{\text{Not faulty parts}}{\text{Total parts}}=\frac{56}{60}[/tex]

[tex]\frac{\text{Not faulty parts}}{12,000}=\frac{56}{60}[/tex]

[tex]\frac{\text{Not faulty parts}}{12,000}\times 12,000=\frac{56}{60}\times 12,000[/tex]

[tex]\text{Not faulty parts}=56\times 200[/tex]

[tex]\text{Not faulty parts}=11,200[/tex]

Therefore, approximately [tex]11,200[/tex] parts will have no faults in a similar batch of 12,000 parts.

The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).

Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.

So the answer is (3,0) and (0,6).

Step 1: Simplify both sides of the equation.

4(2x−3)=4

(4)(2x)+(4)(−3)=4(Distribute)

8x+−12=4

8x−12=4

Step 2: Add 12 to both sides.

8x−12+12=4+12

8x=16

The Royal Fruit Company produces two types of fruit drinks. The first type is 60% pure fruit juice, and the second type is 85% pure fruit juice. The company is

attempting to produce a fruit drink that contains 70% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 160

pints of a mixture that is 70% pure fruit juice?

Answers

Answer: 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).

Step-by-step explanation:

This question is a system of equations. First, we will define our variables:

Let x= number of pints of the first fruit drink (60% pure fruit juice), and then y = the number of pints of the second fruit drink(85% pure fruit juice).

We know that there are 160 total pints of the mixture. Therefore,

x + y = 160 .......... equation i

We are also aware that 70% of those 160 pints will be pure fruit juice, and they will come from either x or y.

For x pints of the first juice, there is

0.6x of pure fruit juice and for y pints of first juice, there is 0.85y of pure fruit juice. Therefore, we will have:

0.6x + 0.85y = 160 × 0.7

0.6x + 0.85y = 112

Multiply through by 100 to remove decimal. This will be:

60x + 85y = 11200 ........... equation ii

Combine both equations

x + y = 160 .......... i

60x + 85y = 11200 ........ ii

Multiply equation i by 60

Multiply equation ii by 1

60x + 60y = 9600 ........ iii

60x + 85y = 11200 ......... iv

Subtract iv from iii

-25y = -1600

y = 1600/25

y = 64

Since x + y = 160

x = 160 - 64

x = 96

Therefore , we will need 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).
