The cost of one plum in pence is 9p. The cost of 1 lime in pence is 12p.
Comparing the cost plum is cheaper.
The cost of 1 plum can be found by dividing the total cost of 7 plums by 7:
63 p / 7 = 9 p
Therefore, the cost of 1 plum is 9 p.
The cost of 1 lime can be found by dividing the total cost of 5 limes by 5:
60 p / 5 = 12 p
Therefore, the cost of 1 lime is 12 p.
Comparing the costs of 1 plum and 1 lime, we see that 1 plum costs 9 p and 1 lime costs 12 p. Therefore, the plum is cheaper per item.

Dawn spent $22. 5 on 9 gallons of gas.
What is the un-simplified rate of dollars-gallons, and gallons to dollars.
And what is the Simplified Unit Rate "per language" of dollars per gallon. And gallons per dollar?
Un-simplified rate of dollars-gallons = 22.5/9 $ and and gallons to dollars 9/22.5 $ . and simplified rate of dollars-gallons = 22.5/9 $ = 2.5 and and gallons to dollars 9/22.5 = 0.4 .
Here first we have to calculate the rate of gallons of gas as per gallons so for that we will find the rate of 1 gallons for that we will divide the 22.4$ to 9 gallons so ans is 22.5$/9 is the rate for 1 gallons
and 2nd we have to calculate the amount of gas as per $ like we have to calculate the the amount if we spend 1 $ so for that we will divide 9 gallons / 22.5$ = 9/22.5

Ms. Rod rolls a 6-sided die . If she rolls the die 57 times, how many times should she expect to roll a composite number?
By understanding what composite numbers are and how they relate to rolling a die, we can determine the expected number of times Ms. Rod will roll a composite number in 57 rolls.
A composite number is a positive integer that has at least one positive divisor other than one or itself. In other words, a composite number is a number that can be factored into smaller positive integers.
To find the number of times Ms. Rod should expect to roll a composite number, we need to know how many numbers from 1 to 6 are composite. Only two numbers are prime in this range, namely 2 and 3. This means that the other four numbers (4, 5, and 6) are composite. Therefore, out of the 6 possible outcomes of rolling the die, 4 of them are composite numbers.
We can use this information to calculate the expected number of times Ms. Rod will roll a composite number. We know that she is rolling the die 57 times, and each roll has a probability of 4/6 (or 2/3) of resulting in a composite number. Therefore, we can use the formula for the expected value of a discrete random variable, which is:
Expected value = (number of trials) x (probability of success)
Plugging in the values, we get:
Expected value = 57 x 2/3
Expected value = 38
Therefore, we can expect Ms. Rod to roll a composite number about 38 times out of 57 rolls. However, it's important to note that this is just an expected value, and the actual number of times she rolls a composite number may vary.

at a cricket match there are 27500 people correct to the nearest 100
calculate the upper bound for the difference between the number of people at the football match and at the cricket match
The upper bound for the difference between the number of people at the football match and at the cricket match is 29750<=p<=29849 .
p = number of people
The true value of p is unknown, but we know that it rounds to 29800 when rounding to the nearest hundred people.
The smallest p could be is 29750 since that rounds to 29800.
The largest is 29849; note that 29850 rounds to 29900.
We have this interval 29750<=p<=29849
r = the rate in which the people leave
This rate is in "people per minute".
Like p, the true value of r is unknown.
The midpoint of 350 and 400 is (350+400)/2 = 375, which represents the smallest value r could be if we round to the nearest 50.
The value 374 would round to 350.
On the other side of the spectrum, (400+450)/2-1 = 425-1 = 424 rounds to 400 as well when rounding to the nearest 50.
The value 425 rounds to 450.
To wrap this section up, you have this interval 375<=r<=424
Summary so far:
29750<=p<=29849
375<=r<=424
where p is the number of people and r is the rate in which they leave (in people per minute).
If we have the smallest number of people (29750) and the highest rate in which they leave (424), then we'll get the lower bound of how long it takes everyone to leave.
This can be thought of as the floor value.
time = (number of people)/(rate)
time = (29750)/(424)
time = 70.1650943396227
time = 70.165
Hence, the upper bound for the difference between the number of people at the football match and at the cricket match is 29750<=p<=29849 .

Is the product of (x − 3)2 a perfect square trinomial? Explain your reasoning
Yes, the product of (x - 3)^2 is a perfect square trinomial because it can be written as the square of the binomial (x - 3).
A perfect square trinomial is a trinomial of the form a^2 + 2ab + b^2, where a and b are terms that can be squared. When we expand the square of a binomial, we get a perfect square trinomial.
In this case, the binomial is (x - 3), and its square is (x - 3)^2. When we expand this expression, we get:
(x - 3)^2 = (x - 3)(x - 3) = x^2 - 6x + 9
This is a perfect square trinomial, because it can be written as the square of the binomial (x - 3). Specifically, we can write:
(x - 3)^2 = (x - 3)(x - 3) = (x - 3)^2
Therefore, the product of (x - 3)^2 is a perfect square trinomial.

3 Hassan recorded the number of people in 60 passing cars.
Here are his results. Find:
a the missing frequency
b the modal number of people in a car
c the median
d the mean.
a) The missing frequency is 20
b) The modal number of people in a car is 1
c) The median is 3
d) The mean is 0.95
The sum of the frequencies must be 60.
The missing frequency by subtracting the sum of the other frequencies from 60
60 - (28 + 3 + 7 + 1 + 1) = 20
To find the median, we need to arrange the data in order from smallest to largest:
1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5, 6
There are 60 numbers in total, so the median is the average of the 30th and 31st numbers:
median = (3 + 3)/2 = 3
The mode is the value with the highest frequency, which is 1.
mean = (1 x 28 + 2 x 20 + 3 x 3 + 4 x 7 + 5 x 1 + 6 x 1) / 60
= (28 + 40 + 9 + 28 + 5 + 6) / 60

(-2, 2) and (4, -1) lie on a line, what is the equation of the line?
As (-2, 2) and (4, -1) lie on a line the equation of the line is: y = (-1/2)x + 1
We can use the slope-intercept form of a linear equation,
which is y = mx + b, where m is the slope and b is the y-intercept.
First, we need to find the slope of the line using the two given points. The slope formula is:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
Plugging in the values, we get:
m = (-1 - 2) / (4 - (-2)) = -3/6 = -1/2
Now we have the slope (m = -1/2), and we can use either of the two given points to find the y-intercept (b).
Let's use the first point (-2, 2):
y = mx + b
2 = (-1/2)(-2) + b
2 = 1 + b
b = 1

Step-by-step explanation:
Shawna is playing a game that involves rolling a black numbered cube and a red numbered cube. The result of a red numbered cube represents a negative number, and the result of a black numbered cube represents a positive number. Shawna’s current score is 4. Then, Shawna rolls a red 5 and a black 3. Write and solve an equation to represent Shawna’s new score
Shawna's new score can be represented by the equation is New Score = Current Score + (Result of Black Cube) + (Result of Red Cube). So, Shawna's new score is 2.
In the game that Shawna is playing, rolling the black cube results in a positive number, while rolling the red cube results in a negative number. We are told that Shawna's current score is 4, which means that she has accumulated 4 points up to this point in the game.
Next, we are told that Shawna rolls a red 5 and a black 3. This means that the red cube resulted in a negative 5 and the black cube resulted in a positive 3.
To calculate Shawna's new score, we can add the results of these two rolls to her current score. However, we need to be careful to subtract the negative number, rather than adding it. This is because a negative number is actually a decrease in score.
Therefore, we can use the following equation to calculate Shawna's new score:
New Score = Current Score + (Result of Black Cube) + (Result of Red Cube)
Substituting in the values that we know, we get:
New Score = 4 + 3 + (-5)
Simplifying, we can combine the positive and negative numbers:
New Score = 4 - 2
Therefore, Shawna's new score is 2. This means that after rolling a red 5 and a black 3, her score has decreased by 2 points from her original score of 4.
