The probability that a club member owns neither a house nor a car is 0.08 or 8%.
As per the survey of a club's members-
percentage of members who own a home 40% = 0.4
percentage of members who own a car → 90% = 0.9
Further, 95% of the homeowners also own a car
⇒ percentage of members who own a car as well as a home = 95% of 40%
= 95/100 x 40/100
= 3800/10000
= 0.38
Let P(A) be the probability that a member owns a home and P(B) be the probability that a member owns a car
we have,
P(A) = 0.4
P(B) = 0.9
also P(A∩B) = 0.38
we need to find the probability that a club member owns neither a house nor a car, that is, P(A'∩B')
According to the rules of probability-
P(AUB) = P(A) + P(B) - P(ANB)
⇒ P(AUB) = 0.4 +0.9 -0.38
P(AUB) = 0.92
Thus, P(A'U B') = 1 - 0.92
= 0.08
Thus, the probability that a club member owns neither a house nor a car is 0.08 or 8%.

Answer:
the bottom left graph is a function
Step-by-step explanation:
for questions like this pertaining a graph, you can use the vertical line test. essentially for a function, an x value cannot have multiple y values. so, the function cannot have any two or more points that lie on the same vertical line.
the top left graph is literally a vertical line, so that doesn't work
the top right is a circle. draw a vertical line and you see it always intersects two points
the bottom right graph draw a vertical line. two points again, right?
only the bottom left works with the vertical line test.

Answer:
83.5
Step-by-step explanation:
Median means middle. So in order to get that you need to write the numbers in order and then get the middle number. If the amount of numbers are even then take the 2 middle ones and add the together then divide by two.
89, 52, 78, 92, 98, 64 --> 52, 64, 78, 89, 92, 98
Since you have 2 middle numbers, you must take the middle 2 (78 and 89) and add them.
78 + 89 = 167
Now divide 167 by 2
167 / 2 = 83.5
Answer = 83.5

A car is driving at 45 kilometers per hour. How far, in meters, does it travel in 5 seconds?
The car travels 62.5 meters in 5 seconds
How to calculate the distance the car travelled ?
The car is driving at 45 kilometres per hour
The first step is to convert kilometres to meters
1 km= 1000 meters
= 45×1000
= 45,000
The next step is to convert hours to seconds
1 hour= 3600 seconds
= 45000/3600
= 12.5
The distance travelled in 5 seconds can be calculated as follows
= 12.5 × 5
= 62.5
Hence the distance travelled in 5 seconds is 62.5 meters

Find the GCF of the two numbers, and rewrite the sum of the two numbers using the distributive property.
12 + 18
Answer:
GCF = 6
The original sum rewrites to 6(2+3)
=================================================
Explanation:
Notice we have these factorizations
12 = 6*2
18 = 6*3
Which shows that 6 is the greatest common factor (GCF)
So,
12+18 = 6*2+6*3 = 6*(2+3)
We use the distributive property which is a(b+c) = ab + ac
I'll leave the 2+3 part un-simplified so that you can see the two original pieces, and how the 6 can multiply with them both to get back to 12+18 again.

A prize is divided into the ratio 5:3 if the difference between the shares is £42 what is the total price?
Ty for helping :)
Answer:
£168
Step-by-step explanation:
Let the total prize be 8x, then the two prizes will be 5x and 3x.
Then, difference between the prizes = 2x
=> 5x - 3x = £42
=> 2x = £42
=> x = £42/2
=> x = £21
As mentioned above, the total prize is 8x.
So, total prize = 8 × x = 8 × £21 = £168

1. How much of the original cake has not been shared
after the first division of the cake? How much of the
original cake has not been distributed after the fourth
division?
2.write a series that represents the amount of the original cake each person has after the fourth division.
3.how much of the original cake will each person have after the fourth division
4. Suppose you continue this process indefinitely. How much of the original cake will each of you receive?
The cake sharing process of the process using geometric progression gives the following values;
1. The amount of the cake left after the first division is one quarter of the cake
The amount of cake remaining after the fourth division is 1/256 of the original cake
2. The series is; (1/4 + 1/16 + 1/64+ 1/256 + 1/1024) of the original cake
3. 341/1024 of the original cake
4. If the process continues indefinitely each person gets (1/3) of the original cake
What is a geometric progression?A geometric progression is a sequence of numbers such that a term is found from the previous term by multiplying the previous term by a constant number.
1. Taking the dimensions of the cake as a square, let x represent the side length of the cake, we have;
Amount of cake left after the first division = x/4
The amount of the cake left after the first division is one quarter of the cakeAmount left after the second sharing = x/(4×4) = x/16
Amount left after the third division = x/(4×4) = x/(16×4) = x/64
Amount left after the fourth division = x/(64×4) = x/256
The amount of cake remaining after the fourth division is 1/256 of the original cake2. After the fourth division, each person receives x/(256×4) = x/1024
The series that represents the amount each person receives after the fourth division is therefore;
(1/4 + 1/16 + 1/64+ 1/256 + 1/1024) of the original cake3. The amount of the original cake each person gets after the fourth division is therefore;
1/4 + 1/16 + 1/64+ 1/256 + 1/1024 = 341/1024 of the original cake4. The amount each person receives is given by the sum of a geometric series up to infinity, where;
The first term, a = 1/4
The common ratio, r = 1/4
S = (1/4)/(1 - (1/4)) = (1/4)/(3/4) = (1/4)×(4/3) = 1/3
The amount of the original cake each gets if the process continues indefinitely is (1/3) of the original cake.

what line is perpendicular to the line passing through the points (-4, 2) and (4, -1)
The line that is perpendicular to the line passing through the points (-4, 2) and (4, -1) is y = (8/3)x + 1/2
Equation of a lineFrom the question, we are to determine the equation of the line that is perpendicular to the line passing through the given points
First, we will determine the equation of the line passing through the given points
The given points are (-4, 2) and (4, -1)
Using the formula,
(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)
x₁ = -4
y₁ = 2
x₂ = 4
y₂ = -1
Thus,
(y - 2)/(x - -4) = (-1 - 2)/(4 - -4)
(y - 2)/(x + 4) = (-3)/(4 + 4)
(y - 2)/(x + 4) = (-3)/(8)
8(y -2) = -3(x + 4)
8y - 16 = -3x -12
8y = -3x -12 + 16
8y = -3x + 4
y = -(3/8)x + 1/2
Now,
NOTE: A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line
In the above equation,
The slope of the line is -3/8
∴ The slope of the line that is perpendicular to the line will be 8/3
Thus,
The equation of the line will be y = (8/3)x + 1/2
Hence, the line that is perpendicular to the line passing through the points (-4, 2) and (4, -1) is y = (8/3)x + 1/2

The displacement (in meters) of a particle moving in a straight line is given by s=6t^3+1t+4 where t is measured in seconds.
Find the velocity of the particle at the times given.
Velocity at time t=1, t=2, t=3, and t=a
Answer:
Velocities
t = 1 : 11 m/s
t = 2 : 27m/s
t = 3: 56.33 m/s
t = a: 6a + 1 + 4/a m/s
Step-by-step explanation:
s(t) = 6t³ + 1t + 4 where s = displacement in meters and t is time in seconds
s(t) = v(t). t where v is the velocity in m/s and t is time in seconds
So v = s/t
At time t = 1
s(1) = 6 x 1³ + 1 x 1 + 4 = 6 + 1 + 4 = 11 meters
v(1) = 11/1 = 11 m/s
At time t = 2
s(2) = 6 x 2³ + 1 x 2 + 4 = 6 x 8 + 2 + 4 = 48+ 2 + 4 = 54 m
v(2) = 54 /2 = 27m/s
At time t = 3
s(3) = 6 x 3³ + 1 x 3 + 5 = 6 x 27 + 3 + 4 = 169 m
v(3) = 169/3 = 56.33 m/s
At time t = a
s(a) = 6a³ + 1a + 4 = 6a³ + a + 4
v(a) = s(a)/a = (6a³ + a + 4)/a = 6a + 1 + 4/a m/s
