The math project scores for two different classes are shown in the box plot below.
(the picture)
Which statement about Class A and Class B math project scores is NOT supported by the graph?
A) The range of scores for both classes is 3.
B) The interquartile range for Class A is greater than the interquartile range for Class B.
C) The interquartile range for Class B is 2.
D) The median score for Class B is 0.5 greater than the median score for Class A.
Answers
Answer:
A
Step-by-step explanation:
The bar for Class A is 1.5-3.5. 3-5 - 1.5 = 2 (interquartile range)
The bar for Class B is 2-3. 3-2 = 1 (interquartile range)
Range = 2-1 = 1
Because the range does not equal to 3, we automatically know that this statement is false. But for D, the line represents the median score for each class.

The graph below shows magazine subscriptions each month for 6 months.
Which equation represents the relationship between x, the number of months and y the number of magazine subscriptions sold?
x + y = 30
y = 30x
y = 30 - x
y = x/30
Answers
Answer:
The incorrect graph is attached.
first choice: y = 30x
second choice: y = x/30
Step-by-step explanation:
The bad news: The graph you attached shows the relationship between numbers of markers and numbers of packages. (y = 8x)
The good news: all proportional relationships are expressed using an equation in the form of y = kx, where k is the constant of proportionality.
So of your choices, y = 30x would be my first answer, and y = x/30 would be my second. Because y = x/30 is the same as y = (1/30)(x).
If there is no accompanying graph, go with y = 30x, as it's not as tricky

Answer:
12(x+ 30)
Step-by-step explanation:
360 is the down payment and 12x is the monthly payment
With regards to the function as monthly we realise there are 12 months in a year so it could equally mean (12 months x amount) or $12 dollars multiplied by x)
Factorising We always put the highest common factor outside of the brackets when dealing with 2 numbers that can include variables such as x or 12x counting as one of the two.
12x+360
12(x+ 30)
Which is done as 12 x 30 = 360
We always try units first in numbers end in zero ie) 30 into 60 is x2 and 30 into 300 is 10 so our first highest common factor is 12 as its our largest number available from the smallest number given being 12.
So 12 is our highest common factor.
A common factor is a factor that is shared by two or more numbers. For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one

Step-by-step explanation:
Given that , the radius of the circle is 3 feet . We need to find the circumference.
We know that the circumference of circle is 2πr . So ,=> C = 2 π r
=> C = 2 × 22/7 × 3ft
=> C = 18.84 ≈ 19 ft
Hence the circumference of the circle is 19 feet.Answer:

If you place a 34-foot ladder against the top of a building and the bottom of the ladder is 25 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answers
Answer:
23.0 ft to nearest 1./0.
Step-by-step explanation:
By Pythagoras:
34^2 = h^2 + 25^2 where h = the height of the building
h^2 = 34^2 - 25^2 = 531
h = 23.04 ft.

Which equation represents the relationship between w, the number of weeks and s the number of skateboards sold?
s = 22w
s = 22/w
s = w/22
s - w = 22
Answers
Answer:
s = 22w
Step-by-step explanation:
We need to try this equation for all of the numbers in the table.
s = 22w
22 = 22 * 1
s = 22w
44 = 22 * 2
s = 22w
66 = 22 * 3
s = 22w
88 = 22 * 4
s = 22w
110 = 22 * 5
Answer:
A. s = 22w
Step-by-step explanation:
22/1 = 22
44/2 = 22
66/3 = 22
88/4 = 22
110/5 = 22

A rectangle’s perimeter is 28 meters and its area is 46 square meters. How long is its
longest side, in meters?
Answers
Answer:
I'm not sure but I think that it is 10.5
Step-by-step explanation:
The longest side is 8.73 meters long
Given that area of rectangle is 48 square meters and perimeter is 28 meters, we need to find the longest side length
What is perimeter and area of a rectangle?
Perimeter = 2(L+B)
Area=L×B
2(L+B)=28
L+B=14....(1)
LB=46....(2)
L=46/B (From2)
Put the value of L in (1)
46/B+B=14
B^2-14B+8=0
By solving above equation we get B=8.73
substitute value of B in 1
L+8.73=14
L=5.27
Therefore longest side in meters is 8.73

Step-by-step explanation:
I looked this up so I'm pretty sure this is correct however it still could be wrong. From my newfound understanding, the water is absorbed and goes up the xylem where most of it goes to the plant and only a small bit is left for the plant to grow
plants need sunlight to make their own food as we've been taught for years. many plants will actually grow toward sunlight. If they're saving that water to grow, they might as well grow toward the sunlight.
