if -10,p,q,20 are in A.P, find p and q
Answers
The value of arithmetic progression of p = 0 and q = 10
What is arithmetic progression ?When there are identical differences between every two next words, the series is known as an arithmetic progression (AP). There is a chance to find a formula for the nth term of the AP using this kind of development. The series 2, 6, 10, 14, etc., for instance, is an example of an arithmetic progression (AP) because it follows a pattern in which each number is acquired by adding 4 to the preceding word.
Given that : -10,p,q,20 are in A.P
if this -10,p,q,20 are in A.P then it must follow
2b = a+ c
2p = -10 + q ... (i)
2q= p+20 ....(ii)
Solving both equation we get
Multiplying (1) with 2,
4p - 2q = -20
Now adding both the equations
4p - 2q + 2q - p = 0
3p = 0
p = 0
Then, q = 0 + 10 = 10

Answers
C. The image shows two right triangles with one pair of congruent leg and congruent hypotenuse. Therefore, the congruence is HL.
D. This shows two right triangles that share one side (a leg) and have the other leg also congruent to each other. Therefore, their congruence is LL and SAS (leg, right angle, leg).
E. This shows two triangles with a pair of congruent sides, a pair of congruent angles, and they have a common side, therefore congruent since they are the same.
So, their congruence is SAS.
F. This shows two right triangles sharing the same hypotenuse, and with a pair of congruent angles. Therefore, their congruence is HA.
G. This shows two right triangles with congruent hypotenuses, one congruent pair of legs, and two congruent pairs of angles (if we include the right angle).
So, their congruence is HA and HL.
H. The two triangles here have a right angle, a pair of congruent sides, and a pair of angles that are opposite by vertex, so they are also congruent angles.
Therefore, their congruence is ASA.

Answer:
<1 = 150 degrees

Step-by-step explanation:
Angle 1 and the 150 degree angle are equal. The reason is because they are on the same side of the transversal (the slanted line) and they are both above the parallel line that makes the up. They are called corresponding angles.
Angle 2 and angle 1 are equal because they are opposite each other. The term used in math is vertically opposite.

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units, then what is the value of k?
k = 2
k equals one half
k = −2
k equals negative one half
Answers
Reason:
To shift down 2 units, we go from f(x) = (0.5)x to g(x) = (0.5)x - 2.
The -2 at the end means we subtract 2 from each y coordinate.
Compare this to g(x) = (0.5)x - k to find that k = 2.

Answers
The mean and standard deviation for the number of correct answers for such students is; μ = 6.5 and σ = 1.802776
How to find the mean and standard deviation?Given there is a surprise true/false test with 13 questions.
Thus, the probability of correctly guessing the answer is; p=0.5
Let "X' be the answers correctly guess by a student.
The formula for the binomial probability distribution is;
P(X = x) = nCx * p^(x) * (1 - p)^(n - x)
A) The mean of the binomial distribution is given by the formula;
μ = np
μ = 13 * 0.5
μ = 6.5
The formula for standard deviation is:
σ = √(np(1 - p))
σ = √(13 * 0.5(1 - 0.5))
σ = 1.802776
B) The probability that the student getting at least 11 correctanswers is given by:
P(X ≥ 11) = P(X = 11) + P(X = 12) + P(X = 13)
Using online binomial probability calculator, we have;
P(X ≥ 11) = 0.01123

if two distinct numbers are selected at random from the first seven prime numbers, what is the probability that their sum is an even number? express your answer as a common fraction.
Answers
The probability that a sum is an even number will be 5/7.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The probability is typically defined as the proportion of favorable outcomes to all outcomes in the sample space. The probability of an event P(E) = (Number of favorable outcomes) is how it is stated (Sample space).So, the first 7 prime numbers:
2,3,5,7,11,13,17Then,
Even numbers are always produced when two odd numbers are added together.Odd numbers are always created when Even numbers are added to Odd numbers.In the list of 7, there is only one even number. If that is one of the options, then the outcome will only be odd.As the same number cannot be chosen twice, there is a 6/7 chance that it won't be chosen the first time and a 5/6 chance that it won't be chosen the second time.By multiplying these two probabilities, we can determine the likelihood of an even sum.
5/6 × 6/730/425/7Therefore, the probability that a sum is an even number will be 5/7.

Determine the range of f(x) = |x| − 4. {y | −∞ < y < ∞} {y | −4 ≤ y < ∞} {y | 0 < y < ∞} {y | 4 < y < ∞}
Answers
The range of the function f(x) = |x| − 4 is {y | −4 ≤ y < ∞}.
Given the function is: f(x) = |x| − 4
first find the domain of the function.
A function's domain and range are its constituent parts. A function's range is its potential output, whereas its domain is the set of all possible input values.
domain= (−∞,∞)
Then, range is he set of all representations of domain elements or the set of all function outputs constitutes the range of the function f.
range = {y | −4 ≤ y < ∞}.
Hence we get the range of the function as {y | −4 ≤ y < ∞}.

Scientific notation is a form of writing a very larger number or very smaller number in a simpler form. The general form of the scientific notation is a number from 1 to 10 is multiplied by a power of 10.
Consider the unknown number as x
The first number = 2×[tex]10^{-6}[/tex]
The result of 2×[tex]10^{-6}[/tex] times x = 6×[tex]10^{-4}[/tex]
So the equation will be
2×[tex]10^{-6}[/tex] × x = 6×[tex]10^{-4}[/tex]
Move 2×[tex]10^{-6}[/tex] to the right hand side of the equation
x = 6×[tex]10^{-4}[/tex] ÷ 2×[tex]10^{-6}[/tex]

What is the equation of the line that passes through the points (-3 , 9) and (9 , -1)? Write in your answer in slope - intercept form.
Please help
(College Algebra)
Answers
The equation of the line that passes through the points (-3,9) and (9,-1) is y= -5x/6 + 39/6 .
The equation of line passing through two points (a,b) and (c,d) is given by the equation
(y-b)=m(x-a) ,
where m is the slope of the line ..
the slope m is (d-b)/(c-a)
In the question ,
it is given that
the required line passes through the points (-3,9) and (9,-1)
by formula m= (-1-9)/9-(-3)
= -10/12
So substituting the values in the formula the equation of the line becomes
y-9 = -10/12*(x-(-3))
12*(y-9) = -10*(x+3)
12y - 12*9 = -10x-30
12y-108= -10x -30
12y = -10x-30+108
12y = -10x + 78
On Dividing both sides by 12 , we get
y= -10x/12 + 78/12
y= -5x/6 + 39/6
Therefore , the equation of the line in slope intercept form that passes through the points (-3,9) and (9,-1) is y= -5x/6 + 39/6 .
