Answer:
(54, 27)
Step-by-step explanation:
2y will represent the larger number.
2y + y = 81
3y = 81
y = 27
x = 2y
x = 2(27)
x = 54
x = 54
y = 27
(54, 27)
Find the value of x.

a) 480 cm3
b) 192 cm3
c) 240 cm
d) 384 cm3
Answer:
B
Step-by-step explanation:
The volume of a prism is the area of the cross section x length
The area of the cross section:
Area of a triangle = [tex]\frac{base * height}{2}[/tex] so [tex]\frac{6*4}{2} = 12[/tex]
12 x 16 = 192 so B

In the LEFT column: Solve for y: 5 = –7y + 8
9514 1404 393
Answer:
y = 3/7
Step-by-step explanation:
add 7y to both sides of the equation
7y +5 = 8
Subtract 5 from both sides of the equation
7y = 3
Divide both sides of the equation by 7
y = 3/7

Step-by-step explanation:
s = a+b+c / 2
= 14+6+9 / 2
= 14.5 feet
Area = √s(s-a)(s-b)(s-c)
= √14.5×(14.5 - 14)×(14.5 - 6)×(14.5 - 9)

Saj wants to go to all 19 home games at a football club.
For each game, a ticket costs £28
A season ticket
costs £379
and
gives entry to all 19 home games.
In total, how much does Saj save by buying a season ticket?
Answer:
£153
Step-by-step explanation:
If Saji bought a normal ticket for all 19 games, they would have to make 19 payments of £28. So, 28*19 would let us know that he would spend £532 in total. Then it's simply 532-379 to find the answer.

Step-by-step explanation:
An eyewitness observes a hit-and-run accident in New York City, where 95% of the cabs are yellow and 5% are blue. A police expert believes the witness is 80% reliable. That is, the witness will correctly identify the color of a cab 80% of the time. If the cab is actually yellow, there is an 80% chance the witness will assert it is yellow, and if the cab is actually blue, there is an 80% chance the witness will assert it is blue. If a witness asserts the cab was blue, what is the probability that the cab actually was blue
Answer:
0.1739 = 17.39% probability that the cab actually was blue
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Witness asserts the cab is blue.
Event B: The cab is blue.
Probability of a witness assessing that a cab is blue.
20% of 95%(yellow cab, witness assesses it is blue).
80% of 5%(blue cab, witness assesses it is blue). So
[tex]P(A) = 0.2*0.95 + 0.8*0.05 = 0.23[/tex]
Probability of being blue and the witness assessing that it is blue.
80% of 5%. So
[tex]P(A \cap B) = 0.8*0.05 = 0.04[/tex]
What is the probability that the cab actually was blue?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.04}{0.23} = 0.1739[/tex]
0.1739 = 17.39% probability that the cab actually was blue
