Shelly and Terrence completed a different number of tasks in a game. Shelly earned 90 points on each task. Terrence's total points were 20 less than Shelly's total. The expression below shows Terrence's total points in the game:
90x − 20
What does the factor x of the first term of the expression represent? (2 points)
Group of answer choices
The total number of tasks Terrence completed
The total number of tasks Shelly completed
The sum of Shelly's and Terrence's total points
The difference between Shelly's and Terrence's total points
The total number of tasks Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed
The factor 'x' in the expression '90x - 20' represents the total number of tasks that Terrence completed in the game.
To understand why, let's break down the given information. It states that Shelly and Terrence completed a different number of tasks. Shelly earned 90 points on each task, so the total number of tasks she completed is not represented by 'x'.
On the other hand, Terrence's total points were 20 less than Shelly's total. This means that Terrence's total points can be calculated by subtracting 20 from Shelly's total points. Since Shelly earned 90 points on each task, her total points would be 90 multiplied by the number of tasks she completed.
So, the expression '90x - 20' represents Terrence's total points in the game, where 'x' represents the total number of tasks that Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed, we can calculate his total points.
Therefore, the correct answer is: The total number of tasks Terrence completed.

Answer:
1. Non equivalent, use the distributive property. 5*3=18, 5*4=20, so the equation is now 18y - 20, which is not equal to 15y - 20
2. Same with this one, -4 * -2p = 8p, and -4 * 4 = -16. Now the equation is 8p - (-16), or 8p + 16. Not equivalent.
3. 3*-7x = -21x, and 3*13 = 39. Now the equation is -21x - 39, not equivalent.
4. -6*-4a = 24a, and -6*8 = -48, the equation is now 24a+ (-48), or 24a - 48

Arithmetic Series:
An arithmetic sequence is defined as an algebraic sequence in which each successive term has an equal difference. It is obtained by adding a constant to any preceding term. For the first term 'a' and the tolerance 'd' of the AP, here is a list of commonly used arithmetic progressions to solve various AP related problems:
Common Difference of AP: d = a2 - a1 = a3 - a2 = a4 - a3 = an - a(n-1) nth term of AP.AP: an = a + (n - 1)d of AP Sum of n terms: Sn = n/ 2( 2a+(n-1)d) = n/2(a + l),where l is the last term in the arithmetic progression.
Now,
Sum of n terms = n/2 [ 2a + (n-1)d]
= 50/2 [ 2× 23 + (50 -1)4]
= 25 [46 + 49×4]

Step-by-step explanation:
i used the BEDMAS rule.
first of all i added 5+10 which is in the bracket.
then, i multiplied 5×2 because in bedmas rule .. tho division comes first in BEDMAS. we check what is comes first from multiplication and division.
after that . i multiplied 9999999×6 then, as you know. if a digit is before the bracket is multiplied to the digit inside the bracket. i mutiplied the product of 9999999×6 with 15.
i dunno what you meant by (5+10)%4. so i just assumed that you meant (5+10)÷4. after i got the product of 59,999,994 ×15. i divided it with 4. now as we are done with BEDM. now only addition and subtraction is left. there is no subtraction.. so i added the products and the quotient .
Now... add 5+10+224,999,977.5

A local repair shop charges $109 per hour to fix cars. A new water pump costs $249. 98. How many hours does the mechanic work, if the total cost of installing a new water pump is $849. 48?
The mechanic worked for 5.5 hours to install the new water pump.
Let's assume the mechanic worked for "x" hours to install the water pump.
The cost of the repair work will include the cost of the water pump as well as the labor charges.
The cost of the water pump is given as $249.98.
The labor charges can be calculated by multiplying the hourly rate by the number of hours worked.
So, the labor charges will be $109 multiplied by "x" hours, which is $109x.
Adding the cost of the water pump to the labor charges will give us the total cost of the repair work.
Therefore, we can write the equation as:
$849.48 = $109x + $249.98
Simplifying the equation, we get:
$599.50 = $109x
Dividing both sides by $109, we get:
x = 5.5
Therefore, the mechanic worked for 5.5 hours to install the new water pump.

At a carnival, a particular game requires the player to spin a wheel. When a child plays, the game operator allows them to continue to spin the wheel until they win a prize. Define x = the number of spins a child takes until they win a prize. Which, if any, of the following requirements for x to be a binomial random variable is violated in this setting?.
In this scenario, the following conditions for X to be a binomial random variable are broken:
(A) There will be a set number of trials.
(E) This environment satisfies all standards.
What is a binomial random variable?The binomial distribution with parametric n and p is the discrete random variable distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure.
It is used in probability theory and statistics.
So, a player will spin the wheel here till a prize is won.
The letter "X" indicates how many spins a youngster must complete before winning a prize.
Currently, let's go over each of the options in turn:
Option (a): It isn't true, as it has already been stated in the question, that they can keep spinning the wheel until they win a prize.
Option (b): It is legitimate because no trial depends on any other trial.
Option (c): It is legitimate because the wheel can only produce one of two results: WIN or LOOSE.
Option (d): It is legitimate because there are only two possible results when the wheel is spun, hence the odds of winning and losing are equally equal to half.
Because Option (a) does not satisfy the criterion, Option (e) is invalid.
Therefore, in this scenario, the following conditions for X to be a binomial random variable are broken:
(A) There will be a set number of trials.
(E) This environment satisfies all standards.

y(5)-8y(4)+13y"-8y"+12y'=0.
NOTE: Use C1,C2,C3,c4, and c5 for the arbitrary constants.
y(t)=
The general solution of the given differential equation, y⁽⁵⁾ - 8y⁽⁴⁾ + 13y⁺⁺ - 8y⁺ + 12y' = 0, can be found by solving the characteristic equation. The general solution is y(t) = C₁e^t + C₂e^(2t) + C₃e^(3t) + C₄e^(4t) + C₅e^(5t), where C₁, C₂, C₃, C₄, and C₅ are arbitrary constants.
To find the general solution, we start by assuming a solution of the form y(t) = e^(rt), where r is a constant. Substituting this into the differential equation, we obtain the characteristic equation r⁵ - 8r⁴ + 13r² - 8r + 12 = 0. We solve this equation to find the roots r₁ = 1, r₂ = 2, r₃ = 3, r₄ = 4, and r₅ = 5.
Using these roots, the general solution can be expressed as y(t) = C₁e^t + C₂e^(2t) + C₃e^(3t) + C₄e^(4t) + C₅e^(5t), where C₁, C₂, C₃, C₄, and C₅ are arbitrary constants. Each exponential term corresponds to a root of the characteristic equation, and the constants determine the particular solution.

Which of these statements is true for f(x) = (1/2)^x
A. The domain of f(x) is x>0.
B. The range of f(x) is y>1/2
C. It is always increasing.
D. The y-intercept is (0,1).
This can be confirmed by plugging x = 0 into the function to find that...
y = (1/2)^x
y = (1/2)^0
y = 1
Recall that any nonzero value to the 0th power leads to 1. So we can say x^0 = 1 as long as x is not zero.
---------------
Extra info (optional section):
We can rule out choice A because negative x values work in the domain. For instance, if x = -1, then it leads to y = (1/2)^x = (1/2)^(-1) = 2. The negative exponent will apply the reciprocal operation to the base fraction.Choice B can also be ruled out because the range is y > 0. Or you could note that it is possible to get positive y values smaller than 1/2. Try x = 2 and you'll see it leads to y = 1/4 which is not greater than 1/2.Choice C is false as well. The function f(x) = (1/2)^x is decreasing throughout the domain. A graph visually would show this due to it going downhill when moving from left to right. A table of values is a non-visual way to see we have a decreasing function. The table would show that y decreases when x increases.Answer:
D. The y-intercept is (0,1).

Identify the equation of a line that passes through (1, 10) and (-4,-5).
O A)x1= 3(y - 10)
O B) y 1 = 3(x - 10)
OC) y-10=(x - 1)
O D) y 10 = 3(x - 1)
Answer:
y = 3x - 7
Step-by-step explanation:
We can use the two-point form formula to find the equation of a line that passes through two given points (x1, y1) and (x2, y2):
y - y1 = (y2 - y1) / (x2 - x1) * (x - x1)
where (x1, y1) and (x2, y2) are the two points and (x, y) represents any point on the line.
Using the given points, we have:
x1 = 1, y1 = 10
x2 = -4, y2 = -5
Substituting these values into the formula, we get:
y - 10 = (-5 - 10) / (-4 - 1) * (x - 1)
Simplifying the equation, we have:
y - 10 = 3(x - 1)
Expanding and rearranging, we get:
y = 3x - 7
Therefore, the equation of the line that passes through (1, 10) and (-4, -5) is y = 3x - 7

In mathematics, an angle is a measure of the amount of rotation between two lines or planes. It is measured in units of degrees or radians. An angle is formed by two rays that have a common endpoint called the vertex. The rays are the sides of the angle and the vertex is the point where the rays meet.
An angle is defined by its measure, which is the amount of rotation between the two rays. The most common way to measure angles is in degrees, where a full rotation is equal to 360 degrees. Another way to measure angles is in radians, where a full rotation is equal to 2*pi radians.
Let the bearing of H from P be represented by x°.
tanθ=3060=0.5
θ=tan−1(0.5)=26.565°
x=180°+(90−26.565)
x=180+63.435=243.435°
= 243°26′
Hence, the bearing of H from P is 243°26′
