If I lost 4% of 100 pencils an 6% of 200 pens how many pencils do I have left and how many pens do I have left?
Answers
100•.04=4
Then subtract
100-4=96 *you have 96 pencils left*
To find 6% of 200, multiply 200 by .06
200•.06=12
Then subtract

The estimated regression equation by least squares method minimizes the sum of the Group of answer choices Absolute deviations between actual and predicted y values Differences between actual and predicted y values. Squared differences between actual and predicted y values None of the choices Absolute deviations between actual and predicted x values.
Answers
Answer:
Squared differences between actual and predicted y
Step-by-step explanation:
The least squares regression method used in predictive modeling for linear regression models produces a best fit line which will minimize the square of the mean difference between the actual and projected or predicted values of the dependent, y variable. Hence, the when the sum of the squared value of the difference between the actual and predicted values (residual) are taken, the fit which gives the minimum sum of squared value is the best fit line upon which the estimated regression equation is based.
The true statement is that the estimated regression equation by least squares method minimizes the sum of the (c) Squared differences between actual and predicted y.
In regression, the least square method is used to estimate quantities.
This is done in order to minimize the sum of the squares of the differences between the observed values and the estimated values.
In this case, the observed value and the estimated values represent the actual and predicted y
Hence, the true statement is that the estimated regression equation by least squares method minimizes the sum of the (c)

i don’t need a explanation i just need a answer pls hurry!!
Answers
Answer:
6,656 square meters
Step-by-step explanation:
Surface area of triangular pyramid = bh + L(S1 + S2 + S3)
Where,
b = 48 m
h = 32 m
L = 40 m
S1 = 40 m
S2 = 40 m
S3 = 48 m
Plug in the values
Surface area = 48*32 + 40(40 + 40 + 48)
= 1,536 + 5,120
= 6,656 m²

What is the approximate length of the base of the parallelogram in the diagram?
Answers
Answer:
2piR
Step-by-step explanation:
The base of the parallelogram is equal to the circumference.
The length of the base of the parallelogram will be πr.
What is Parallelogram? What is triangle? What is a expression? What is a mathematical equation?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.We have a circle converted into a parallelogram as shown.
The angle subtended by each arc at the center =
Ф = (360°/8) = 45°
Length of each arc will be -
L = (Ф/360°) x 2πr
L = (45/360) x 2πr
L = (5/40) x 2πr
L = 1/8 x 2πr
L(A) = πr/4
Length of the base will be -
L(B) = 4 x L(A) = 4 x πr/4 = πr
Therefore, the length of the base of the parallelogram will be πr.
