Answer:
220km
Step-by-step explanation:
Time taken (t) = 2hrs 45 min
= 2.75 hrs
AV =80km/hrs
Displacement or Distance (d) =?
We have,
AV = d÷t
80 = d÷2.75
80 × 2.75 = d
d = 220km

There are 15 tiles in a bag. Of these, 7 are purple, 5 are black and the rest are white.
Event A = drawing a white tile on the first draw
Event B = drawing a purple tile on the second draw
If two tiles are drawn from the bag one after the other and not replaced, what is P(B|A) expressed in simplest form?
A. 1/5
B. 1/3
C. 7/15
D. 1/2
Answer: C.
Step-by-step explanation: If I am wong I am sorry !
Probability of drawing two tiles from the bag one after the other and not replaced that is P(B/A) is equals to [tex]\frac{1}{2}[/tex].
What is probability?" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Conditional probability ' P(B/A)' = P(A∩B) / P(A)
According to the question,
Total number of tiles = 15
Number of while tiles represented by 'A' = 3
Number of purple tiles represented by 'B' = 7
Number of black tiles= 5
Total number of outcomes = 15 × 14
= 210
Favourable outcome for A = 3 × 14
= 42
Favourable outcomes for A∩B = 3 × 7
= 21
Probability of A
'P(A)' = [tex]\frac{42}{210}[/tex]
Probability of A∩B
'P(A∩B)' = [tex]\frac{21}{210}[/tex]
Substitute the value in the conditional probability we get,
Probability for P(B/A) = [tex]\frac{\frac{21}{210}}{\frac{42}{210} }[/tex]
= [tex]\frac{1}{2}[/tex]
Hence, Option(D) is the correct answer.

There are 130 people in a sport centre.
61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?
The probability that this person does not make use of the facility is 7/130
How to solve for the probability61+68+60 - 25-28-19 + 6
= 123
The total number of person in the sport center is given as 130
We have 130 - 123 = 7
This means that there are a total of 7 persons that do not make use of this facility.
Hence the probability of a person not using the facility is 7/130

A triangle is shown
What is x?
What is y?
What is z?
Answer:
x = 44
y = 136
z = 136
Step-by-step explanation:
The angles of a triangle have to add up to 180°
54 + 82 + x = 180
136 + x = 180
x = 44
We know that y and z are vertical angles, so they have the same measurements.
Also, x and the other angle across from it are also vertical angles.
88 + 2n = 360
2n = 272
n = 136
Therefore,
x = 44
y = 136
z = 136

Deion is making sandwiches for a picnic. He uses 2 slices of cheese to make each sandwich,
and he has a package of cheese with 24 slices. How many sandwiches can Deion make before
he runs out of cheese?
answer quickly please!
Answer:
12 sandwiches
Step-by-step explanation:
We know that Deion has 24 cheese slices, and uses 2 slices per sandwich, so in order to find how many sandwiches he can make, we can divide the total number of cheese slices by the number used to make a sandwich:
24 / 2 = 12
Therefore, Deion can make 12 sandwiches before he runs out of cheese.
