Answer: The usual number of yellow eggs in the selected sample is 26.
Step-by-step explanation:
It is given that there are 2 types of dragon eggs: Yellow and green
Observation says that 39% of the eggs are yellow.
When selected at random for incubation:
Number of eggs selected are = 66
To evaluate the number of yellow eggs, we must calculate 39% of 66 eggs
[tex]\Rightarrow \frac{39}{100}\times 66\\\\\Rightarrow 25.74\approx 26[/tex]
Hence, the usual number of yellow eggs in the selected sample is 26.

Answer:
(8,5):
8 is x-axis
5 is y-axis
What is the value of x?
2

7
Answer:
x = 2
Step-by-step explanation:
AE is equal to the sum of AB and BE because of segment addition postulate, we can substitute to get AE = 11 + x + 1 = x + 12
DE is equal to the sum of DC and CE because of segment addition postulate, we can substitute to get DE = 1 + x + 4 = x + 5
To solve the problem, we can use power of a point, more specifically exterior secants products scenario. In this case, we can get the equation:
AE * BE = DE * CE
Now, we can substitute and solve:
(x + 12)(x + 1) = (x + 5)(x + 4)
x^2 + 13x + 12 = x^2 + 9x + 20
13x + 12 = 9x + 20
4x + 12 = 20
4x = 8
x = 2

Congruent angle pairs : Find value of x
Answer:
(Opt.B) 18
Step-by-step explanation:
4x = 2y - x (vertically opposite angles are equal)
4x + x = 2y
5x = 2y ----- (1)
4x + 2y + x = 180 (Linear pair angles)
5x + 2y = 180
From (1) we can understand that, the value of 5x and 2y is the same. So,
5x + 5x = 180
10x = 180
x = 180/10
x = 18
Just completing,
Putting the value of x in (1)
5*18 = 2y
90 = 2y
90/2 = y
45 = y

solve the equation (-10x + 1 + 7x = 37)
Answer:
x = - 12
Step-by-step explanation:
- 10x + 1 + 7x = 37
- 3x + 1 = 37
- 3x + 1 - 1 = 37 - 1
- 3x = 36
- 3x ÷ - 3 = 36 ÷ - 3
x = - 12
Answer: x = -12
Step-by-step explanation: first you combine like terms/simplify the equation: -10x + 1 + 7x = 37 turns into -3x + 1 = 37.
then subtract 1 from both sides: -3x + 1 = 37 then -3x + 1 - 1 = 37 - 1 then -3x = 37 - 1 then -3x = 36.
then divide both sides of the equation by -3 and then you're done

=15511210043330985984000000/(6402373705728000*5040)
= 480,700

250
Step-by-step explanation:
Given
[tex]n =3[/tex] --- digit code
[tex]First = Even[/tex]
[tex]Last=Odd[/tex]
Required
The different combination of codes
The set of even number is:
[tex]Even = \{0,2,4,6,8\}[/tex]
The set of odd is:
[tex]Odd = \{1,3,5,7,9\}[/tex]
This means that:

The last can be any of the 5 odd digits
Since there is no restriction in selection;
The [tex]second[/tex] can be [tex]any[/tex] of [tex]the[/tex] 10 digits

Write an in Standard Folm given the following points:
(-2, 6), (9,8)
Answer:
2/11 x + 70/11
Step-by-step explanation:
Given the coordinate (-2, 6), (9,8), the equation in standard form is of the form y = mx+b
m is the slope = 8-6/9-(-2)
m = 2/11
Get the y-intercept
Substitute m = 2/11 and (-2, 6) into the expression y = mx+b
6 = 2/11(-2)+b
6 = -4/11 + b
b = 6 + 4/11
b = (66+4)/11
b = 70/11
Get the required equation
y = 2/11 x + 70/11
Hence the required equation is 2/11 x + 70/11

Answer:
"D" (the fourth one....(7,1),(6,2)....
a "function" is a very specific relationship in math...
for a relationship to be "a function" every possible INPUT (x-values) has to map (correspond) to a UNIQUE output value (Y-value)
a line is a function (all x's have unique y values.
A circle is NOT ..... at the center (x-value) there are two y values (one above and one below)

Which inequality represents the graph?
Answer:
y ≤ x - 2
Step-by-step explanation:
Using the coordinate points on the graph (0, -2) and (2,0)
The general equation of the line will be y = mx+b
Slope m = 0-(-2)/2-0
m = 2/2
m = 1
From the coordinate (0, -2), this shows that the y intercept is -3
Get the equation
y = 1x + (-2)
y = x - 2
Since the line is a thick line and shaded towards the negative y-axis, the required inequality expression will be y ≤ x - 2

8p²-18p² need help from brainliest
Answer:
- 10p2
Step-by-step explanation:
p(8p - 18 p)
p x -10p
ans = -10p2
Answer: -10p²
This is the same as saying -10p^2
============================================
Explanation:
Both terms 8p² and -18p² are like terms.
We combine them in much the same way as 8-18 = -10, just with a p² attached to everything.
So 8p² - 18p² = (8-18)p² = -10p²
The coefficient -10 is negative because we're subtracting small minus big. If it was the other way around, then we'd get a positive value.

42 8x-2
Using cross products
49 ( 8x-2) =42 (63)
Divide each side by 49

8x -2 = 54
Add 2 to each side
8x = 56
Divide b 8

At which angle will the hexagon rotate so that it maps
onto itself?
O 60°
90°
0 120°
O 180°
Answer:
60 degress
Step-by-step explanation:
Edgen 2021
60° is the angle at which the hexagon rotate so that it maps onto itself.
What is Polygon?A polygon is a plane figure made up of line segments connected to form a closed polygonal chain.
When a figure has a rotational symmetry, it maps onto itself under rotation about a point at the centre.
When an hexagon rotate onto itself,the vertices must cover to vertices and from sides to sides.
There are six angles in a hexagon and the sum of the angles is 360°. Therefore, each angle has a measure of 360°/6 is equal to 60°.
Rotating subsequently by 60 degree will rotate a hexagon onto itself. A hexagon has 6 rotations, that is, a hexagon has a rotational symmetry of 6 and at angle 60°, the hexagon will rotate onto itself.
Hence, 60° is the angle at which the hexagon rotate so that it maps
onto itself.

The diagonals of a rectangle are AC = 5x-4 and BD = 7x-18.
Solve for x
Answer:
x = 7
Step-by-step explanation:
The diagonals of a rectangle are congruent , so
BD = AC , that is
7x - 18 = 5x - 4 ( subtract 5x from both sides )
2x - 18 = - 4 ( add 18 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7

At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed?
a. |19|
b. |-19|
c. |-30|
d. |-38|
Answer:
c. |-30|
Step-by-step explanation:
It wants the change from 11 to -19. While normally absolute value is the distance from zero, zero can be shifted. Depending on where you are in learning about absolute value, the midway point can change from zero to, say, 4. This is called a transformation and is typically represented on a graph. Simple answer is that zero is shifted to 11. Therefore, absolute value changes from distance away from zero, to distance away from 11.
