Answer:
4/663
Step-by-step explanation:
1/13 = probability of ace (as 1st card)
4/51 = probability of jack (as 2nd card) -->
4/663
The probability that the first card is an Ace and the second card is a Jack without replacement will be 0.00603318 or 4/663.
What is probability?The probability of an event occurring is defined by probability.
Probability is also known as chance because, if you flip a coin, the likelihood that it will land on its head or tail is nothing more than the chance that either the head or the tail will occur.
In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
Without replacement will be dependent events.
Probability of dependent events
P(A and B) = P(A) × P(B/A).
Probability of the first card as Ace = 4/52 ( 4 are Aces out of 52 cards)
Probability of the second card as jack = 4/51 ( since 1 ace has been removed)
P( Ace and Jack ) = 4/52 × 4/51 = 4/663 = 0.00603318
Hence the probability that the first card is an Ace and the second card is a Jack will be 0.00603318.

6
Answer:
ig D)))))))...
Step-by-step explanation:
......
6*4x = 24x
6*(-10) = -60
24x - 60 = 84
Add 60 to both sides
24x = 144
Divide both sides by 24
x = 6
A large purple bowl contains 5 blue marbles and 3 pink marbles. What is the probability a blue marble is drawn, replaced, and a second blue marble is drawn?
Answer:
[tex]\frac{25}{64}[/tex]
Step-by-step explanation:
Blue Marbles =5
Pink Marbles =3
Total =3+5=8
Probability of drawing two marbles with replacement
=P(First Blue Marble AND Second Blue Marble)
=P(First Blue Marble) X P(Second Blue Marble)
[tex]=\frac{5}{8}X \frac{5}{8}\\\\=\frac{25}{64}[/tex]

The entertainment committee at Maplecrest Junior High School has narrowed down the theme of the Spring Dance to three choices. The ten committee members want to conduct a survey to determine which theme Maplecrest's 2000 students prefer. There will be three choices (Disco Fever, The Crazy Eighties, or Hip Hop Til You Drop) and the committee will go with the theme that gets the most votes.
Which of the following survey methods will allow the committee to make a valid conclusion about which theme Maplecrest's student body prefers?
Choose 1 answer:
Choose 1 answer:
(Choice A)
A
Each of the 10 committee members can ask 10 friends to obtain a sample of 100 students.
(Choice B)
B
Assign a number to each student, and use a computer program to generate 100 random numbers between 1 and 2000. Ask those students whose numbers are selected.
Answer:
B
Step-by-step explanation:
To make the survey fair, every student in the school has to have an equal chance to be selected to take the survey. The first scenario would only allow friends of the committee members to be selected, but the second one would give a chance to all students.

What is the positive solution to the equation 0 = –x2 + 2x + 1? Quadratic formula: x = StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction
Answer:
x = 2 + √2
x = 2 - √2
Step-by-step explanation:
- x² + 2x + 1 = 0
x² - 2x - 1 = 0
Here,
a = 1
b = - 2
c = - 1
Now,
Discriminant
D = b² - 4ac
= (-2)² - 4(1)(-1)
= 4 + 4
= 8
=2√2 > 0
Real and Distinct roots
x = - b +- √b² - 4ac/2a
= - (-2) +- √ = (-2)² - 4(1)(-1)/2(1)
= 2 +- √4 + 4/2
= 2 +- √8/2
= 2 +- 2√2/2
= 2 +- √2
x = 2 + √2 or x = 2 - √2
Answer:
x = 2 + √2 or x = 2 - √2

Jack bought a motorbike. The original price was $1,300, but he got a discount of 20%.
What was the discounted price of the bike?
Answer:
The discounted price is $260
Step-by-step explanation:
Jack bought a motorbike. The original price was $1,300, but he got a discount of 20%.
What was the discounted price of the bike?
To find the discounted price of the bike, if Jack bought a motorbike that originally costs $1300 and got a discount of 20%, we will follow the steps below;
find 20% of $1300
20% of $1300 = 20% × $1300 =[tex]\frac{20}{100}[/tex] × $ 1300 = 20×$13 = $ 260
Therefore, the discounted price is $260
Write 21 9/1000 in decimal form
Answer:
the answer in decimal form is 21.009
Answer:
= 21.009
Step-by-step explanation:
First change it to an improper fraction
= 1000 x 21 + 9
= 21009/ 1000
You then divide it by 1000 without leaving a remainder.
= 21.009

Answer: 14.4
Step-by-step explanation: To find the third side of the triangle, we have to use the pythagorean theorem...

Point N′(7, –8) is the image of point N(7, 8) under a reflection. What is the image of (–4, –10) under the same reflection?
Answer:
Image of the point (-4, -10) after reflection will be (-4, 10).
Step-by-step explanation:
Point N(7, 8) when reflected across x-axis, coordinates of the image point become N'(7, -8).
Rule for the reflection over the x-axis is
(x, y) → (x, -y)
Under the same reflection or following the same rule rule,
(-4, -10) → (-4, +10)
Therefore, image of the point (-4, -10) after reflection will be (-4, 10)
Write the ratio of the first measurement to the second measurement. Compare in millimeters. Diameter of ball A: 44 mm diameter of ball B: 7.2 cm The ratio of the diameter of ball A to the diameter of ball B is
Answer:
11:18
Step-by-step explanation:
Here, we are interested in calculating the ratio of diameter of ball A to that of ball B
what to do here is to ensure that both diameters have measurements that are same units.
Thus, mathematically;
44 mm to 7.2cm
But, mathematically;
10 mm = 1 cm
Thus 7.2cm = 7.2 * 10 = 72mm
Thus, our ratio becomes;
44:72
divide through be 4, we have
44/4 : 72/4
= 11 : 18
Answer:
11:19

solve 6n + 12 - 8n = 22
Answer:
n = -5
Explanation:
6n + 12 − 8n = 22
[ Simplify both sides of the equation ]
6n + 12 − 8n =22
6n + 12 + −8n = 22
(6n + −8n) + (12) = 22 [Combine Like Terms]
−2n + 12 = 22
−2n + 12 =22
[ Subtract 12 from both sides ]
−2n + 12 − 12 = 22 − 12
−2n = 10
[ Divide both sides by -2 ]
-2n / -2 = 10 / -2
n = -5
Answer:
n = -5
Step-by-step explanation:
6n + 12 - 8n = 22
Combine like terms
-2n +12 = 22
Subtract 12 from each side
-2n +12-12 = 22-12
-2n =10
Divide each side by -2
-2n/-2 = 10/-2
n = -5
