Answer:
Given that A cereal manufacturer decides to offer a new family-sized box based on the regular-sized box. They want the volume of the family-sized box to be three times the volume of the regular-sized box. However, they want the length of the family-sized box to be the same as the regular-sized box.
If original dimensions are l,w and h then volume = lwh
Volume of new box is= 3lwh
But here w becomes 2w and l remains the same. Let h' be the new height
Then we have
So by 1.5 factor height should be dilated.

Answer:

Step-by-step explanation:
Note: It seems the question is wrong when it states the relationship of distance. If d is the distance from the ground, at t = 0, we get d = 0 too which means with no time spent, Math Man hits the ground.
It assumed d = t²*0.25 is the distance from the top of the building.
We know the height of the building is 500 meters.
We need to find the value of t, when d = 500 m:
0.25t² = 500t² = 500/0.25t² = 2000t = √2000t = 44.7 units of time (assumed seconds)The gravitational force on a body falling towards the earth is directly proportional to the

The equation would be y = kx with k being a constant.
Direct variationAssuming the gravitational force is y and the mass of the body is x. y is directly proportional to the x.
Mathematically,
y = kx where k = constant.

Class A has 10 pupils and class B has 18 pupils. Both classes sit the same maths test. The mean score for class A is 34. The mean score for both classes is 55. What is the mean score (rounded to 2 DP) in the maths test for class B?
Answer:
Mean score for the class B is 66.66
Step-by-step explanation:
Mean : It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list.
Mean = sum of all numbers/ total numbers
Given,
mean score of class A = 34.
mean score of both the classes = 55
mean score of class a = sum of marks/total strength of class
34 = sum of marks/10
340 = sum of marks of class A
similarly, Mean score of both classes
= ( sum of marks of class A and class B)/(total students in both classes)
= (340 + sum of marks of class B)/ 28
55 = (340 + sum of marks of class B)/ 28
55 × 28 = (340 + sum of marks of class B)
1540 - 340 = sum of marks of students of class B
1200 = sum of marks of students of class B
now to find Mean score of class B

The table gives some information about the heights of 30 plants. Height, h in cm Frequency 0
Answer:
C. 20 ≤ h < 30
Step-by-step explanation:
Median
The value in the middle of the data set when all the data values are placed in order of size.
As this is grouped data, we can only estimate the median.
Add an extra row to the table showing the Cumulative Frequency:
[tex]\begin{array}{|c|c|c|}\cline{1-3} \sf Height & \sf Frequency & \sf Cumulative\:Frequency \\\cline{1-3} \sf 0 \leq h < 10 & 1 & 1 \\\cline{1-3} \sf 10 \leq h < 20 & 9 & 10 \\\cline{1-3} \sf 20 \leq h < 30 & 7 & 17 \\\cline{1-3} \sf 30 \leq h < 40 & 13 & 30 \\\cline{1-3}\end{array}[/tex]
To find which class the median is in, divide the total number of data values by 2:
[tex]\implies \sf \dfrac{n}{2}=\dfrac{30}{2}=15[/tex]
Therefore, there are 15 values less than or equal to the median.
From the table, the 11th to 17th data values are in class 20 ≤ h < 30. Therefore, the median must be in the 20 ≤ h < 30 class.

The IQR for male data is 10, the estimated difference between medians is 2, the box plot for males is symmetric and for females, the box plot is left side skewed.
What is the box and whisker plot?A box and whisker plot is a method of abstracting a set of data that is approximated using an interval scale. It's also known as a box plot. These are primarily used to interpret data.
From the box plot:
Part A:
IQR for males data:
IQR = Q3 - Q1
The estimated value of Q3 is 15 (between 10 and 20)
The estimated value of Q1 is 5 (between 0 and 10)
IQR = 15 -5 = 10
Part B:
= Median(male) - Median(femal)
= 10 - 8
= 2
Part C:
The box plot for males is symmetric and for females, the box plot is left side skewed.
Part D:
There can be holidays for the outliers
Thus, the IQR for male data is 10, estimated difference between medians is 2, the box plot for males is symmetric and for females, the box plot is left side skewed.

Answer:
angle s = 22
angle r = 117
angle q = 41
Step-by-step explanation:
so all of the angles equal to 180 degrees in a triangle
so you add all of t he angles like this:
x+5x+7x+2x-3=180
collect all of the like terms,
8x + 4 = 180
subtract 4 from both sides, which leaves you with 8x = 176
divide both sides by 8 leaving x on its own.
x = 22
angle s = 22
angle r = (5x22)+7 which is 117
angles q = (2x22)-3 which is 41
