Step-by-step explanation:
Answer:
-16n - 41
Step-by-step explanation:
(2 • (-n - 3)) - 7 • (2n + 5)

Answer:
3.) (5,2), (5,5), and (9,2)
Step-by-step explanation:
The triangle currently has the coordinates (2,0), (6,0), and (2,3).
If you want to translate the triangle up 2 units, you need to add 2 to each "y" value.
(2,0) -----------> y = 0 ------------> new y = 2
(6,0) -------> y = 0 --------------> new y = 2
(2,3) ----------> y = 3 -----------> new y = 5
If you want to translate the triangle 3 units to the right, you need to add 3 to each "x" value.
(2,0) -----------> x = 2 ------------> new x = 5
(6,0) -------> x = 6 --------------> new x = 9
(2,3) ----------> x = 2 ----------> new x = 5
Therefore, the new coordinates are (5,2), (9,2), and (5,5).

A jar contains 8 red marbles, 6 blue ones, and 6 yellow ones. One marble is chosen at random. The color is
recorded in the table, and then it is returned to the jar. This is repeated 40 times.
Red Blue Yellow

Answer:
Step-by-step explanation:
Comment
The theoretical probabilities are
Red: 8/20 = 0.4
Blue:6/20 = 0.3
yellow:6/20 = 0.3
The experimental Probabilities are
Red: 11/40 = 0.275
blue: 11/40 = 0.275
Yellow: 18/40=0.45
Both probabilities add to 1 as they should
The yellow is the highest disproportionate answer and it really shouldn't be. If anything it should be red. (0.45 > 0.4 comparing yellow experimental with red theoretical. The yellow is way more than it should be)
The number of trials is double the number of marbles in the jar. The number of trials would be double for each color in the jar. Both blanks are double.
The vertices of an isosceles triangle are a(3, 6), b(7, 2), and c(4, 3). what is the equation of the triangle's line of symmetry?
y = x + 1
y = x - 1
y = x
y = -x + 1
Based on the calculations, the equation of the triangle's line of symmetry is equal to: B. y = x - 1.
How to determine the equation of the triangle's line of symmetry?First of all, we would determine the midpoint where the line of symmetry passes through points A and B:
Midpoint at point A = (3 + 7)/2 = 10/2 = 5.
Midpoint at point B = (6 + 2)/2 = 8/2 = 4.
Point D = (5, 4)
Mathematically, the standard equation of a line is given by y = ax + b.
D(5, 4); 4 = 5a + b ....equation 1.
C(4, 3); 3 = 4a + b ....equation 2.
Subtracting eqn. 2 from eqn. 1, we have:
1 = a
Next, we would find the value of b:
4 = 5a + b
4 = 5(1) + b
b = 4 - 5
b = -1.
Therefore, the equation of the triangle's line of symmetry is given by:
y = ax + b
y = x(1) + (-1)
y = x - 1.

Formula for finding out the area of the figure -
Area of full rectangle - Area of unshaded rectangle = Area of shaded region
Area of full rectangle =
Length (l) = 9+3 = 12 cmBreadth (b) = 4+4 = 8cm Area of full rectangle = l*b = 12*8 = 96cm2Area of unshaded rectangle =
Length (l) = 9 cmBreadth (b) = 4 cmArea of unshaded rectangle = l*b = 4*9 = 36cm2Putting the formula = 96-36 = 60cm2

The equation of a circle is given below:
x squared minus 8 x plus y squared plus 6 y minus 11 equals 0
Identify the center and radius of the circle.
Group of answer choices
center: left parenthesis 4 comma minus 3 right parenthesis
radius: 6
center: left parenthesis negative 8 comma 6 right parenthesis
radius: 6
center: left parenthesis 4 comma minus 3 right parenthesis
radius: 36
center: left parenthesis negative 8 comma 6 right parenthesis
radius: 36
The center of the circle will be (4, -3) and the radius of the circle will be 6 units. Then the correct option is A.
What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at the (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x - h)² + (y - k)² = r²
The equation is given below.
x² - 8x + y² + 6y - 11 = 0
x² - 8x + y² + 6y = 11
Then the center and the radius of the circle will be
x² - 8x + 16 + y² + 6y + 9 = 11 + 16 + 9
(x - 4)² + (x + 3)² = 36
(x - 4)² + (x + 3)² = 6²
Thus, the center and the radius of the circle will be (4, -3) and 6 units respectively.

Using the Empirical Rule, it is found that about 143 trees fall within two standard deviations of the mean.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.95% of the measures are within 2 standard deviations of the mean, hence, out of 150 trees, the amount is:
