saras bookshelf is 40cm long 50 cm wide and 900 mm high she wants to paint it and calculated its volume as 180000cm3 check if theres something wrong if yes show your working for correction
ill mark u
Answer:
The volume of the bookshelf is 180000 cm³.
Step-by-step explanation:
The dimensions of the bookshelf are 40 cm, 50 cm and 900 mm.
We know that,
1 mm = 0.1 cm
900 mm = 90 cm
Now the dimensions become 40 cm, 50 cm and 90 cm.
The volume of the bookshelf can be calculated as :
V = lbh
Substitute all the values,
V = 40 cm × 50 cm × 90 cm
V = 180000 cm³
So, the volume of the bookshelf is 180000 cm³.
-4t+ 14 = -9t+ 24

A realtor collects the data set given in DS 12.2.4 concerning the sizes of a random selection of newly constructed houses in a certain area together with their appraised values for tax purposes.
1. Fit a linear regression model with appraised value as the explanatory variable and size as the dependent variable.
2. What is the estimate of the error variance?
Answer:
12.327X + 452.084
45206.327
Step-by-step explanation:
The linear regression model obtained by fitting the data using technology is :
ŷ = 12.327X + 452.084
Where, 12.327 = slope ; 452.084 = Intercept ; X = appraised value ; y = Area
The estimated error variance which is the degree of variation between the actual and predicted value.
Error variance = ΣSSE /n-2
n = sample size = 15
ΣSSE = 587682.2638
Error variance = 587682.2638/13
Error variance = 45206.327

The number of books checked out at two different libraries each day this week are shown below. (at bottom)
How do the median number of books checked out each day compare?
A.
The median number of books checked out at Ryder is equal to the median number of books checked out at Williams.
B.
The median number of books checked out at Ryder is 23 more than the median number of books checked out at Williams.
C.
The median number of books checked out at Williams is 25 more than the median number of books checked out at Ryder.
D.
The median number of books checked out at Ryder is 18 more than the median number of books checked out at Williams.
Answer:
the answer is B.
Step-by-step explanation:
W= median is 58
R= median is 81
81-58=23
The median number of books checked out at Ryder is 23 more than the median number of books checked out at Williams.
What is Median?The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
Given data ,
Let the data of Williams be represented as W
Now , W = { 63 , 56 , 60 , 55 , 62 , 55 }
And , the data of Ryder be R
where R = { 80 , 75 , 82 , 84 , 82 , 79 }
And , the median of Williams = (56 + 60) / 2 = 58
And , the median of Ryder is = 81
So , the difference of medians = 81 - 58 = 23
Hence , median number of books checked out at Ryder is 23 more than Williams

How do we decide if a situation requires us to measure in square units or cubic units?
Answer: see below...
Step-by-step explanation:
Square units are when we are finding the surface area.
Since it is side x side, so ^2.
Cubic units are when we are finding the volume.
Since it is side x side x side, so ^3.

find the volume of the solid formed by revolving the region bounded by the graphs of y = 4x - x^2 and f(x) = x^2 from [0,2] about the... a) x-axis.
Answer:
[tex]v = \frac{32\pi}{3}[/tex]
or
[tex]v=33.52[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4x - x^2[/tex]
[tex]g(x) = x^2[/tex]
[tex][a,b] = [0,2][/tex]
Required
The volume of the solid formed
Rotating about the x-axis.
Using the washer method to calculate the volume, we have:
[tex]\int dv = \int\limit^b_a \pi(f(x)^2 - g(x)^2) dx[/tex]
Integrate
[tex]v = \int\limit^b_a \pi(f(x)^2 - g(x)^2)\ dx[/tex]
[tex]v = \pi \int\limit^b_a (f(x)^2 - g(x)^2)\ dx[/tex]
Substitute values for a, b, f(x) and g(x)
[tex]v = \pi \int\limit^2_0 ((4x - x^2)^2 - (x^2)^2)\ dx[/tex]
Evaluate the exponents
[tex]v = \pi \int\limit^2_0 (16x^2 - 4x^3 - 4x^3 + x^4 - x^4)\ dx[/tex]
Simplify like terms
[tex]v = \pi \int\limit^2_0 (16x^2 - 8x^3 )\ dx[/tex]
Factor out 8
[tex]v = 8\pi \int\limit^2_0 (2x^2 - x^3 )\ dx[/tex]
Integrate
[tex]v = 8\pi [ \frac{2x^{2+1}}{2+1} - \frac{x^{3+1}}{3+1} ]|\limit^2_0[/tex]
[tex]v = 8\pi [ \frac{2x^{3}}{3} - \frac{x^{4}}{4} ]|\limit^2_0[/tex]
Substitute 2 and 0 for x, respectively
[tex]v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ \frac{2*0^{3}}{3} - \frac{0^{4}}{4} ])[/tex]
[tex]v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ 0 - 0])[/tex]
[tex]v = 8\pi [ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ][/tex]
[tex]v = 8\pi [ \frac{16}{3} - \frac{16}{4} ][/tex]
Take LCM
[tex]v = 8\pi [ \frac{16*4- 16 * 3}{12}][/tex]
[tex]v = 8\pi [ \frac{64- 48}{12}][/tex]
[tex]v = 8\pi * \frac{16}{12}[/tex]
Simplify
[tex]v = 8\pi * \frac{4}{3}[/tex]
[tex]v = \frac{32\pi}{3}[/tex]
or
[tex]v=\frac{32}{3} * \frac{22}{7}[/tex]
[tex]v=\frac{32*22}{3*7}[/tex]
[tex]v=\frac{704}{21}[/tex]
[tex]v=33.52[/tex]

you would have to solve for y so you subtract the 7 on both sides. then it is in slope-intercept form which is y=mx+b where m is slope and b is the y-intercept. the slope would be 4 and the y-intercept would be -7
