Answer:
5.5
Step-by-step explanation:
2,3,3,4,5,7,8,8,8,10,10,12
The mean of this data is 7.5. So what you are trying to figure out is the mean between 2 and 7. Since that is 3 and 4 it would be 3.5. So 3.5 is the Q1. Now you have to figure out the mean between 8 and 12. That is 9. This is Q3. You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer. I hope that made sense.

You have recently purchased a new backpack as show in the picture. The main section of the backpack is made of a rectangle gular prism. Use the diagram to find the volume of your new backpack, then explain how u calculated the answer. Use the pictures with the formulas to help also use the sentence starters.
Sentence Starters:
The volume of the large rectangular prism (the bottom part of the backpack) is __inᶾ.
The volume of the pocket, which is also a rectangular prism is _____ inᶾ.
The volume of the half cylinder, which is the top curve of the backpack, is _____ inᶾ.
When you add all three of these together, you get the total volume of _____ inᶾ.
Hint: Find the volume of each shape; there are 3 of them; two rectangular prisms and half of a cylinder, and then add all 3 of them together. For the cylinder, you only need half, so find the volume of the whole cylinder then divide it by 2 for half. )
Answer:
Main part of backpack V = 840 inᶾ
Front pocket of backpack V = 64 inᶾ
Top curve of the backpack V = 395.8406744 inᶾ
Total V = 1299.840674 inᶾ
Step-by-step explanation:
1.
As we know, the formula for the volume of a rectangular prism is width x height x length (V = whl). We will use this formula to find the volume of the large rectangular prism (bottom part of the backpack) and the volume of the smaller rectangular prism (the pocket). As for the cylinder, we know the formula for the volume of a cylindrical prism is pi x radius squared x height (V = πr^2h). We will use this formula to find the volume of the half cylinder (top curve of the backpack).
2.
For the large rectangular prism (main part of the backpack), we are given:
w = 7in
h = 10in
l = 12in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 7 x 10 x 12
V = 840 inᶾ
3.
Now for the smaller rectangular prism (front pocket of backpack), we are given:
w = 2in
h = 4in
l = 8in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 2 x 4 x 8
V = 64 inᶾ
4.
Now to calculate volume for the half cylinder (top curve of the backpack), we must first imagine that this is a full, circular cylinder. We are given:
r = 6in
h (which will be the same as the width of the backpack in this case scenario) = 7in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V* = πr^2h
V* = π x 6^2 x 7
V* = 791.6813487 inᶾ (round this number if you must)
Now that we have the volume of a whole cylinder, we can halve it (divide by two) since we only need half of the cylinder.
V = V*/2
V = 791.6813487/2
V = 395.8406744 inᶾ (round this number if you must)
5.
Finally, we can add our volumes together to acquire the volume of the backpack as a whole!
Large rectangular prism (bottom part of the backpack) + Smaller rectangular prism (the pocket) + Half cylinder (top curve of the backpack) = Total Volume (Whole backpack)
Recall that:
Large rectangular prism (bottom part of the backpack) = 840 inᶾ
Smaller rectangular prism (the pocket) = 64 inᶾ
Half cylinder (top curve of the backpack) = 395.8406744 inᶾ
So:
Total Volume (Whole backpack) = 840 inᶾ + 64 inᶾ + 395.8406744 inᶾ
Total Volume (Whole backpack) = 1299.840674 inᶾ (round this number if you must)
can someone help me on this problem what does it mean by a “smaller zero”? what is the zero
Answer:
(c) -2/5
Step-by-step explanation:
A "zero" or "root" or "x-intercept" of a function is a value of the independent variable (x) that makes the function (f(x)) have a value of zero. It is found where the graph of the function crosses the x-axis.
A quadratic function will have two (2) zeros. If they are different, one will be smaller than the other (leftmost on the number line).
Difference of squaresYou may recognize that 25x² and 4 are both perfect squares, (5x)² and 2², respectively. That means the expression (25x² -4) is the difference of squares.
The difference of squares is a special polynomial form, useful for the way it factors:
a² -b² = (a -b)(a +b)
Here, that means the factored form of f(x) is ...
f(x) = (5x -2)(5x +2)
Zero product ruleThe "zero product rule" says a product can only be zero if one or more factors is zero. This is exceptionally useful for determining the zeros of a polynomial function from its factored form.
It tells us f(x) = 0 only when one of (5x-2) = 0, or (5x+2) = 0. These are simple equations to solve to find the corresponding values of x:
5x -2 = 0 ⇒ 5x = 2 ⇒ x = 2/5
5x +2 = 0 ⇒ 5x = -2 ⇒ x = -2/5
Zeros of f(x)The above tells us the zeros of f(x) are -2/5 and 2/5. These values of x make f(x) = 0. The smaller zero is the one that is more negative: -2/5.
smaller zero: -2/5
__
Additional comment
A polynomial may have complex zeros. Only the real zeros will be x-intercepts on a graph of the function. Complex zeros must be found another way, not by graphing.

A pyramid has a volume of 1,944 inches cubed and a rectangular base with the dimensions 18 inches by 9 inches. What is the height of the pyramid? 4 in. 12 in. 24 in. 36 in.
Answer: 4 inches
Step-by-step explanation: 1,944 / 18/ 9 / 1/3 = 4
Based on the calculations, the height of this pyramid is equal to: D. 36 inches.
Given the following data:
Volume of pyramid = 1,944 cubic inches.Dimensions of rectangular base = 18 inches by 9 inches.How to calculate the height of this pyramid?Mathematically, the volume of a pyramid is calculated by using this formula:
Volume = 1/3 × b × h
Where:
b is the base area.h is the height.For the base area, we have:
Base area = length × breadth
Base area = 18 × 9
Base area = 162 square inches.
Substituting the given parameters into the formula, we have;
1,944 = 1/3 × 162 × h
1,944 = 54h
h = 1,944/54
Height, h = 36 inches.

question: the solutions of a quadratic equation are x=-7 and 5. which could represent the quadratic equation and why?
Answer:
B) x²+2x-35=0; the factors are (x+7)(x-5)
Step-by-step explanation:
The quadratic equation which has the solutions as x = -7 and 5 may be x² + 2x - 35 = 0, the factors are (x + 7) and (x - 5) and (x + 7)(x - 5) = x² + 2x - 35.
What are Quadratic Equations?Quadratic equations are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
Given that,
a quadratic equation has the solutions x = -7 and 5.
There are two options, x² + 2x - 35 and x² - 2x - 35
Using the factorization method, a quadratic equation ax² + b x + c = 0 can be factored as (x + p)(x + q) where pq = c/a and p + q = b/a.
Consider, x² + 2x - 35 = 0
There are numbers 7 and -5 that 7 - 5 = 2 and 7 × -5 = -35
So it can factored as,
(x + 7) (x - 5) = 0
Solutions are x = -7 and x = 5
Hence the quadratic equation is x² + 2x - 35 = 0.

Finding the LCD is pretty simple here, it has to at least be the highest denominator, which is 9, and since 3 goes into 9 evenly we get a LCD of 9.
Then to make the fractions correct we do 2/3 x 3/3 which is 6/9.
So now we figure out 6/9 - 1/9 which is just subtracting the numerator so 6/9 - 1/9 = 5/9 and since that is the most it can be simplified, 5/9 is our answer. Hope this helps!
