Patricia was having fun playing poker. She needed the next two cards dealt to be spades so she could make a flush (five cards of the same suit). There are 12 cards left in the deck, and three are spades. What is the probability that the two cards dealt to Patricia (without replacement) will both be spades? Answer choices are in percentage format, rounded to the nearest whole number.

Answers

Answer 1

Answer:

4.5% ≈ 5%

Step-by-step explanation:

Given Data :

number of cards left in the deck = 12

number of spades left = 3

Patricia needs 2 spades

Calculate the probability that the two cards dealt ( without replacement ) will both be spades

1st case: ( first card is a spade )

number of cards left in the deck = 12

number of spades left = 3

P( first card dealt is spade ) = 3 / 12 = 1/4

2nd case ( second card is a spade )

number of cards left = 11

number of spades left = 2

p( second card dealt is spade ) = 2/11

Hence the probability that the two cards dealt ( without replacement ) will both be spades

= 1st case * 2nd case

= 1/4 * 2/11

= 2 / 44 =  1 / 22 =  0.045  = 4.5% ≈ 5%

Answer 2

Answer:

5%

Got it right on the test.

Two high schools, Jefferson Hills East and Jefferson Hills West are taking field trips to the state capital. A total of 408
students from Jefferson Hills East will be going in 3 vans and 6 buses. A total of 516 students from Jefferson Hills West
will be going in 6 vans and 7 buses. Each van has the same number of passengers and each bus has the same number of
passengers.

Answers

Answer:

see explanation!

Step-by-step explanation:

If Jefferson Hills East takes 3 vans and each van has xx students, then 3x3x students will ride in vans. If the school takes 6 buses and each bus has yy students, then 6y6y students will ride in buses. The total number of students is then 3x+6y3x+6y. It is given that the school has 408 students so 3x+6y=4083x+6y=408.

If Jefferson Hills West takes 6 vans and each van has xx students, then 6x6x students will ride in vans. If the school takes 7 buses and each bus has yy students, then 7y7y students will ride in buses. The total number of students is then 6x+7y6x+7y. It is given that the school has 516 students so 6x+7y=5166x+7y=516.

The system of equations is then { 3x+6y=408 6x+7y=516  

{

3x+6y=408

6x+7y=516

Point C is the image of A after a translation two units to the right, then a reflection using the x-axis.

The coordinates of point C are (
,
).

Answers

Using translation concepts, the coordinates of point C, considering A(x,y), are given as follows:

C(x + 2, - y).

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, we have that:

The translation two units right is represented by x -> x + 2.The reflection over the x-axis is represented by y -> -y.

Hence the coordinates of point C, considering A(x,y), are given as follows:

C(x + 2, - y).

What are the 'x' and 'y' intercepts of the equation 2y + 17 = 6x - 19?

Answers

Answer:

x=6,0

y=0,-18

Step-by-step explanation:

Answer:

x-intercept: (6,0)

y-intercept: (0,-18)

Step-by-step explanation:

To find the x-intercept, set y=0 and solve for x.

2y=+17=6x-19

0+17=6x-19

6x=36

x=6

(6,0)

To find the y-intercept, set x=0 and solve for y.

2+17=6x-19

2y+17=0-19

2y=-36

y=-18

What is the coefficient of the term with a degree of two in the product of (2m-9) and (m^2+3m-4)

Answers

Answer:

-3

Step-by-step explanation:

First, identify the different possible ways to multiply 2 monomials and get an m^2 term: we can multiply a constant by an m^2 term, or we can multiply an m term by an m term.

Now, we can identify all the combinations of the products that will give a m^2 term:

m^2*-9=-9m^2

3m*2m=6m^2

Now, we just combine the 2 m^2 terms:

-9m^2+6m^2=-3m^2

Therefore, the coefficient of the term with a degree of 2 is -3.

Two professors teach two sections A and B of the same class. Thecourse scores in section A follow a Gaussian random variable of mean 76 and variance64. The course scores in section B follow a Gaussian random variable of mean 67 andvariance 36. What is the probability that the scores of two students, one in sectionA and one in section B, differ by no more than 1 point in absolute value

Answers

Answer:

Step-by-step explanation:

Let A denote the score for students of section A.

Let B denote the score for students of section B.

It is provided that:

[tex]A\sim N(76,64)\\B\sim N(67,36)[/tex]

The scores of the students of the two section are independent.

Compute the mean and variance of A - B as follows:

[tex]E(A-B)=E(A)-E(B)=76-67=9\\\\V(A-B)=V(A)+V(B)-2Cov(A,B)=64+36-0=100[/tex]

Compute the probability that the scores of two students, one in section A and one in section B, differ by no more than 1 point in absolute value as follows:

[tex]P(|A-B|\leq 1)=P(-1\leq X-Y\leq 1)[/tex]

                        [tex]=P(\frac{-1}{10}\leq \frac{(X-Y)-E(X-Y)}{\sqrt{V(X-Y)}}\leq \frac{1}{10})\\\\=P(-0.10<Z<0.10)\\\\=P(Z<0.10)-P(Z<-0.10)\\\\=0.53983-0.46017\\\\=0.07966\\\\\approx 0.08[/tex]

Thus, the probability that the scores of two students, one in section A and one in section B, differ by no more than 1 point in absolute value is 0.08.

332/10 as an mixed number

Answers

Answer:

27 2/3

Step-by-step explanation:

Hope this helps :)

Answer: 33 & 1/5

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 332 by 10 and keep only what is to the left of the decimal point:

332 / 10 = 33.2000 = 33

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

332 - (10 x 33) = 2

Step 3 - Put Together

Keep the original denominator and use the answers from Step 1 and Step 2

Step 4 - Minimize

Minimize the fraction part from Step 3 by dividing the numerator and denominator by 2, which is the greatest common factor, to get the final answer. 332/10 as a Mixed Number.

Answers

Answer:

[tex]\mathbf{P(X =11 ) \simeq 0.1429}[/tex]

Step-by-step explanation:

The objective of this question is to find the probability that:

Exactly 11 of them major in STEM

So, Let assume X to be the random variable that follows a binomial distribution:

Then [tex]X \simeq Bin ( 36, 0.31)[/tex]

The probability that exactly 11 of them major in STEM can be computed as:

[tex]P(X =11 ) = ^{36} C_{11} (0.31)^{11} (1-0.31) ^{36-11}[/tex]

[tex]P(X =11 ) = \dfrac{36!}{11!(36-11)!} \times (0.31)^{11} \times (0.69) ^{25}[/tex]

[tex]P(X =11 ) = \dfrac{36!}{11!(36-11)!} \times (0.31)^{11} \times (0.69) ^{25}[/tex]

[tex]P(X =11 ) =600805296 \times (0.31)^{11} \times (0.69) ^{25}[/tex]

[tex]\mathbf{P(X =11 ) \simeq 0.1429}[/tex]

Thus; the probability that exactly 11 of them major in STEM is 0.1429
