The probability that I will go sailing today AND the fair six-sided die will come up even on the next roll is .3.
these events are independent, what is the probability that I will go sailing today?

Answers

Answer:

Step-by-step explanation:

Let us consider P(A) to be the probability for the fact that I will go for sailing today

Likewise, P(B) will be the probability of a die to come up on an even number in the next roll.

Now, according to the question,

P(A and B) = 0.3

It is known to us that the probability of a die to land with an even number on its side up =  

Moreover, we are given with the fact that both P(A) and P(B) are independent.

∴ P(A and B) = P(A) × P(B)

⇒ 0.3 = P(A) × 0.5

⇒ P(A) =  = 0.6

A coffee shop sells 5 different types of cake and 6 different kind of drinks. Ruby wants to order a cake and a drink. How many different combinations of cake and drink could she choose?

Answers

Answer:

She could choose 30 different combinations of cake and drink

Step-by-step explanation:

A coffee shop sells 5 different types of cake and 6 different kind of drinks.

This means that:

For each type of cake, there are 6 different kind of drink.

At all, there are 5 different types of cake.

So

6*5 = 30

She could choose 30 different combinations of cake and drink

When a card is selected from a deck, find the probability of getting a. A club b. A face card or a heart c. A 6 and a spade d. A king e. A red card

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Number of clubs = 13

Number of face cards = 12

Number of hearts = 13

Number of King's = 4

Number of reds = 26

Number of spade = 13

Number of 6's = 4

Total possible outcomes = total number of cards = 52

Probability = required outcome / Total possible outcomes

1.) P(A club) = 13 / 52

2.) P(face card or heart) =

p(face card) + p(heart)

12 / 52 + 13/52

= (12 + 13) / 52 = 25 /52

3.)

(A 6 and a spade)

4/52 * 13/52

= 52 / 2704

= 1/52

4.) A king

P(king) = 4 /52 = 1/13

5) A red

P(red) = 26 / 52 = 1/2

How to subtract -2 1/6-2/3

Answers

Answer:

Conversion a mixed number 2 1/6

to a improper fraction: 2 1/6 = 2 1/6

= 2 · 6 + 1/6

= 12 + 1/6

= 13/6

Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/6 = 12/6

To find new numerator: 13/6 - 2/3= 13/6 - 2 · 2/ 3 · 2 = 13/6- 4/6= 13 - 4/6= 9/6= 3 · 3/3 · 2= 3/2

Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13

Write a previous answer (new numerator 13) over the denominator 6.

Two and one sixth is thirteen sixths

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(6, 3) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 3 = 18. In the next intermediate step , cancel by a common factor of 3 gives 3/2

.

In words - thirteen sixths minus two thirds = three halfs.

In a manufacturing plant, a work center is a specific production facility that consists of one or more people and or machines and is treated as one unit for the purposes of capacity requirements planning and job scheduling. If the jobs arriveat a particular work center at a faster rate than they depart, the work center impedes the overall production process and is referred to as a bottleneck. This sample was collected by an operations manager for use in investigating a potential bottleneck work center. There are 315 hours in the work week when items can come into the work center. The manager selects every 15th hour and counts how many items come into the work center during that hour. What type of sample is this?

Answers

Answer:

Systematic sampling

Step-by-step explanation:

Systematic sampling is a sampling technique in which the first sample selection is a random selection but other subsequent selection of samples occurs within a fixed sampling interval. The determination of this interval is based on the division of the population size by sample size.

Let assume that, our first random selection is [tex]i^{th}[/tex] unit, then the other fixed selection occurs at a fixed sampling interval of k.

Therefore, using systematic sampling method, the sampling unit will be every [tex]k^{th}[/tex] unit after the [tex]i^{th}[/tex] unit.

From  the question given:

We notice that the manager selects a sampling unit every 15th  hour. This tells us that he is taking the sampling unit by the usage of a fixed time interval.

Hence, this appears to be a systematic sample.

Pentagon ABCDE is similar to pentagon RSTUV . The perimeter of pentagon ABCDE is 36.8 centimeters.


What is the length of ST ?

19.8 cm
18 cm
25.8 cm
15 cm

Answers

Answer:

ST = 15 cm

Step-by-step explanation:

find BC first by adding four other sides and subtracting from 36.8

sum of 4 sides is 30.8, so BC = 6

Now find ST by creating a proportion from corresponding sides:

BC / ST = DE / UV

6 / ST = 13.2 / 33

Cross-multiply:

13.2ST = 198

ST = 198/13.2

ST = 15

Read the passage from "Not by Math Alone by Sandra Day OConnor and Roy Romer.A healthy democracy depends on the participation of citizens, and that participation is learned behavior; it doesnt just happen. As the 2003 report "The Civic Mission of Schools" noted: "Individuals do not automatically become free and responsible citizens, but must be educated for citizenship." That means civic learningeducating students for democracyneeds to be on par with other academic subjects.This is not a new idea. Our first public schools saw education for citizenship as a core part of their mission. Eighty years ago, John Dewey said, "Democracy needs to be reborn in every generation and education is its midwife."What message do the writers want to convey in this passage? The responsibility of schools is to focus on teaching academic subjects, not civic learning. Public schools no longer see it as their mission to educate students for civic participation.Democracy is fragile and needs to be reborn in every generation through education.Civic education is essential for a functioning democracy, as citizenship is not automatic but learned. blake went on a bike tour he rode 780 miles in 12 days he rode the same number of miles each day write an expression that can be used to find how many miles blake rode each day
