Step-by-step explanation:
we need to calculate the area of big box (prism).
volume = 4 1/2 X 5 X 3 3/4
= 84.375 in³.
volume of small cube = 1/4 X 1/4 X 1/4
= 0.015625 in³.
now we need to find how many of the small ones go into the big one.
84.375/0.015625
= 5400.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

write an equation of the following story problem
Answers
Answer:
5x + 15y =20 = - 3x +25y =75
= 8 minutes
Step-by-step explanation:
5x + 15y =20 multiply all by 3 to get 15x
15x +45y=60
- 3x +25y =75 multiply all by -5 to get 15x
15x -125y = -375
rewrite ans together
15x +45y=60
15x -125y = -375
-80y = -315
y = -315/ - 80
y = 3.9375 = y= 4 substitute to find x
5x + 15(4 )=20
5x +60 = 20
5x=-40
x= -40/5
x=-8
15x +45(4)=60
15x +180 =60
15x =-120

Answers
Answer:
Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart shows the effect of adding or taking away a pamphlet. Pamphlets Added to the box(x) Effect on the Box's Weight (y) 0 0 1 6 2 12 3 18 Is this an example of continuous or discrete data? discrete continuous
Answers
Answer:
This example represents discrete data.
Step-by-step explanation:
Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.
In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.
Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

The figure shows a rectangle inscribed in a circle that has a diameter of 10 feet. Which measurement is closest to the area of the shaded portion of the figure in square feet.
A. 314 ft²
B. 78.5 ft²
C. 266 ft²
D. 30.5 ft²
Answers
The shaded portion of the figure in square feet is 78.5 ft².
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses.
As, its diagonal is equal to the diameter of the circle which is 10 feet.
Let the width of the rectangle be x, then its length is 10-x.
Using the Pythagorean theorem, we can write:
x² + (10-x)² = 10²
2x² - 20x + 100 = 100
2x² - 20x = 0
2x(x-10) = 0
x =10, which means the rectangle is actually a square.
Therefore, its area is 10² = 100 square feet.
Now, the area of the shaded portion is
= area of the circle - area of the square.
Then, Radius is 5 feet.
So, the area of the circle
= π(5²)
= 25π square feet.
Therefore, the area of the shaded portion is:
= 25π - 100
≈ 78.5 square feet.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15
