Answer:
The gradient of the straight line that passes through (2, 6) and (6, 12) is [tex]m = \frac{3}{2}[/tex].
Step-by-step explanation:
Mathematically speaking, lines are represented by following first-order polynomials of the form:
[tex]y = b + m\cdot x[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]m[/tex] - Slope.
[tex]b[/tex] - Intercept.
The gradient of the function is represented by the first derivative of the function:
[tex]y' = m[/tex]
Then, we conclude that the gradient of the staight line is the slope. According to Euclidean Geometry, a line can be form after knowing the locations of two distinct points on plane. By definition of secant line, we calculate the slope:
[tex]m = \frac{y_{B}-y_{A}}{x_{B}-x_{A}}[/tex] (2)
Where:
[tex]x_{A}[/tex], [tex]y_{A}[/tex] - Coordinates of point A.
[tex]x_{B}[/tex], [tex]y_{B}[/tex] - Coordinates of point B.
If we know that [tex]A(x,y) = (2,6)[/tex] and [tex]B(x,y) = (6,12)[/tex], then the gradient of the straight line is:
[tex]m = \frac{12-6}{6-2}[/tex]
[tex]m = \frac{6}{4}[/tex]
[tex]m = \frac{3}{2}[/tex]
The gradient of the straight line that passes through (2, 6) and (6, 12) is [tex]m = \frac{3}{2}[/tex].
What is the lowest common denominator of 1/32 and 2/3
Answer:
96
Step-by-step explanation:
The least common denominator or lowest common denominator is the smallest multiple that the denominator (that is the number on the bottom of a fraction) has in common.
Since 32, and 3 have no common factors, one simply has to multiply them to find the least common denominator.
32 * 3 = 96
What is the volume of the pyramid in cubic millimeters
Answer:
[tex]V=\dfrac{1}{3}\times A\times h[/tex]
Step-by-step explanation:
The volume of the pyramid is given by the formula as follows
[tex]V=\dfrac{1}{3}\times A\times h[/tex]
A is the area of the base
h is height of the pyramid
If the area and height are in millimeters, the volume of the pyramid will be in cubic millimeters.
Line segment AB has a length of 1 unit. It is translated 4 units to the right on a
coordinate plane to obtain line segment A'B'. What is the length of A'B'?
Answer:
1 unit
Explanation:
We know that line segment AB is 1 unit long, and that it is translated 4 units to the right to obtain line segment A'B'. A translation is a type of rigid transformation - which means that the shape stays the same as it is moved on a coordinate plane. Therefore, the length of line segment A'B' would be the same as line segment AB: 1 unit.

A box of 10 flashbulbs contains 2 defective bulbs. A random sample of 2 is selected and tested. Let x be the random variable associated with the number of defective bulbs in the samplea. find the probability distribution of Xb. find the expected number of defective bulbs in a sample
Step-by-step explanation:
The probability of selecting no bad ones is the probability of
selecting 2 from the 8 good bulbs, which is C(8,2)/C(10,2) or it can also be written as (8C2)/(10C2) = 28/45
The probability of selecting 1 good one and one bad one, is the
probability of selecting 1 from the 8 good bulbs, and one from
the 2 bad ones, which is [C(8,1)C(2,1)]/C(10,2) or as some people
write it (8C1×2C1)/(10C2) = 16/45.
The probability of selecting two bad one, is C(2,2)/C(10,2) or
as some people write it (2C2)/(10C2) = 1/45.

The game of roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, where each slot has an equal chance of capturing the ball. a) You watch a roulette wheel spin 7 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin
Answer:
9 / 19
Step-by-step explanation:
Given that:
Number of slots on roulette wheel = 38
Number of red on wheel = 18
Number of black on wheel = 18
Number of green = 2
The probability that ball will land on red slot :
Recall: probability of event (A) = P(A)
P(A) = (number of required outcome / number of total possible outcomes)
Hence,
P(ball lands on red) = (Number of red slots / total number of slots)
P(ball lands on red) = 18 / 38
P(ball lands on red) = 9/ 19
In a right triangle the leg opposite to the acute angle of 30° is 7 in. Find the
hypotenuse and other leg.
Answer:
in the explanation
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the leg opposite to 30 to the leg opposite to 60 to the hypotenuse is 1:[tex]\sqrt{3\\}[/tex]:2.
So, the 7 inch leg is the 1, the other leg is 7[tex]\sqrt{3}[/tex] in and the hypotenuse is 14 in.

in triangle DEF, DE=EF and G is the midpoint of EF. if the measure of GDE=10 what is the measure of E?
Note: It seems you may have forgotten to attach the diagram. Hence, I am attaching the potential diagram of your question.
Answer:
The measure of angle E is:
m∠E = 80°
Step-by-step explanation:
Given
The triangle ΔDEF
m∠GDE = 10°
DE = EF
G = midpoint of EF
To Determine
m∠E =?
Solving
As DE=EF and G is the midpoint of EF.
It means the midpoint G has converted the triangle into two equal right-angles triangles ΔDEG and ΔDFG with the right-angle at G.So, the right angle G is m∠DGE = 90°
as
m∠GDE = 10° m∠DGE = 90° m∠E = ?We know that the sum of angles of a triangle is 180°.
m∠GDE + m∠DGE + m∠E = 180°
10° + 90° + m∠E = 180°
m∠E = 180° - 10 - 90
m∠E = 80°
Therefore, we conclude that the measure of angle E is:
m∠E = 80°What is the answer to number 7

The probability that a women likes the color blue is 10%. The probability of being a women is 40%.What is the probability that a person likes the color blue given that they are a woman?
Answer:
The probability that a person likes the color blue given that they are a woman=0.25%
Step-by-step explanation:
We are given that
The probability that a women likes the color blue=10%=[tex]\frac{10}{100}=0.1[/tex]
The probability of being a women=40%=[tex]\frac{40}{100}=0.4[/tex]
We have to find the probability that a person likes the color blue given that they are a woman.
We know that
Conditional probability formula
[tex]P(A/B)=\frac{P(A\cap B)}{P(B)}[/tex]
The probability that a person likes the color blue given that they are a woman
=[tex]\frac{0.1}{0.4}[/tex]
[tex]=\frac{1}{4}=0.25[/tex]
Hence, the probability that a person likes the color blue given that they are a woman=0.25%

What is the angle made by two parallel lines
Answer:
180°
Step-by-step explanation:
When any 2 lines make an angle of 180° , they are called as parallel lines . In this case both the lines never intersect each other.
When any 2 lines make an angle of 90° , they are called as perpendicular lines . Both the lines intersect each other.
( Usually most get confused in this question and do write 90° or 0° but 180° is the correct answer)

Is -8 - 2(3 + 2x) + 7x equivalent to -30 -13x?
Answer:
They are NOT equivalent.
Step-by-step explanation:
To find if the expressions are equivalent, we have to simplify the first expression.
Solve:
-8 - 2(3 + 2x) + 7x
Use the distributive property.
-8 - 6 - 4x + 7x
Combine like terms.
-14 - 4x + 7x
-14 + 3x
Since they're not the same, this means that the expressions are NOT equivalent to each other.

what's the inequality describes all possible length of AB?
Answer:
We conclude that inequality describes all possible lengths of AB
13 < x < 35Option C is true.
Step-by-step explanation:
We know that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Now, checking the interval of the length of the side 'x', such as:
24 + 11 = 35
24 - 11 = 13
so the possible lengths of the side 'x' will be:
13 < x < 35
Therefore, we conclude that inequality describes all possible lengths of AB
13 < x < 35Hence, option C is true.
What is the surface area of the cuboid 3cm 5cm and 2cm.
Answer:
SA = 62 cm2
Step-by-step explanation:
The surface area of the given cuboid will be 62 cm² whose dimensions are cm, 5 cm, and 2 cm.
What is the formula for the total surface area of a cuboid?The total surface of the cuboid = 2(LB+BH+HL)
Consider that the length, width, and height of the cuboid are L, B, and H.
The cuboid is given in the question
Which has the length, width, and height of the cuboid are 3 cm, 5 cm, and 2 cm.
The surface area of the cuboid = 2(LB+BH+HL)
Here L = 3 cm, B = 5 cm, and H = 2 cm
Substitute the values in the above formula, and we get
The surface area of the cuboid = 2(3 × 5 + 5 × 2 + 2 × 3)
The surface area of the cuboid = 2(15 + 10 + 6)
The surface area of the cuboid = 2(31)
The surface area of the cuboid = 62 cm²
Thus, the surface area of the given cuboid will be 62 cm² whose dimensions are cm, 5 cm, and 2 cm.
