The cost of each pound of grass seed is $6.
A graph of the solution for the cost of each pound of grass seed is shown below.
How to determine the cost of each pound of grass seed?In order to determine the cost of each pound of grass seed, we would assign a variable to the cost of each pound of grass seed and then translate the word problem into an algebraic linear equation.
Let the variable x represent the cost of each pound of grass seed.
Since Lori bought 3.6 pounds of grass seed and she was charged $22.90, including a tax of $1.30, an algebraic linear equation that best represent this situation is given by;
3.6x + 1.30 = 22.90
3.6x = 22.90 - 1.30
3.6x = 21.60
x = 21.60/3.6
x = $6.
In conclusion, we would sue an online graphing calculator to plot the solution for the cost of each pound of grass seed as shown in the image attached below.

14x + 4y = 1
9514 1404 393
Answer:
(b) 7x + 2y = 1
Step-by-step explanation:
You don't need to know how to find the equation. You just need to know how to determine if a point satisfies the equation. Try one of the points and see which equation fits. (The numbers are smaller for point K, so we prefer to use that one.)
7(1) +2(-3) = 1 ≠ -1 . . . . . tells you choice A doesn't work, and choice B does
The equation is ...
7x +2y = 1

Additional comment
The equations of choices C and D have coefficients with a common factor of 2. If the constant also had a factor of 2, we could say these equations are not in standard form, and we could reject them right away. Since the two points have integer values for x and y, we can reject these equations anyway: the sum of even numbers cannot be odd.

number.
Answer:
456
Step-by-step explanation:
Product means an answer derived from multiplication. Therefore, if the product is 155952, and one value is 342, then the following equation is true:
342x = 155952, or 342 * x = 155952
Divide 155952 by 342 to get: 456.
Check the work in the equation:
342(456) = 155952
155952 = 155952, which is true, so the answer is 456.

On a number line, point C is at 8, and the midpoint E of CD is at -3.
Point D is at
on the number line.
Answer: C
Step-by-step explanation:
Point D is at -14 on the number line.
How to determine the midpoint of a line segment?In Mathematics, the midpoint of a line segment with two end points can be calculated by adding each end point on a line segment together and then divide by two (2).
Since E is the midpoint of line segment CD, we can logically deduce the following relationship:
Line segment CD = Line segment C + Line segment D
Midpoint E = (point C + point D)/2
By substituting the given points into the equation above, we have the following:
-3 = (8 + D)/2
-6 = 8 + D
D = -6 - 8
D = -14

A manufacture has been selling 1700 television sets a week at $390 each. A market survey indicates that for each $20 rebate offered to a buyer, the number of sets sold will increase by 200 per week.a) Find the function representing the demand p(x), where x is the number of the television sets sold per week and p(x) is the corresponding price.p(x)= ?b) How large rebate should the company offer to a buyer, in order to maximize its revenue? Please write answer in dollars. c) If the weekly cost function is 110500 + 130x, how should it set the size of the rebate to maximize its profit? Please write answer in dollars.
For each $20 rebate offered to a buyer, the number of sets sold will increase by 200 per week: The slope is (-20/200)
Formula of the slope:
\(m=\frac{f(x_2)-f(x_1)}{x_2-x_1}\)For the given situation:
\(\begin{gathered} f(x_2)=p(x) \\ x_2=x \\ \\ f(x_1)=390 \\ x_1=1700 \\ \\ -\frac{20}{200}=\frac{p(x)-390}{x-1700} \end{gathered}\)Use the equation above to solve p(x) in terms of x:
\(\begin{gathered} -\frac{1}{10}=\frac{p(x)-390}{x-1700} \\ \\ \frac{p(x)-390}{x-1700}=-\frac{1}{10} \\ \\ p(x)-390=-\frac{1}{10}(x-1700) \\ \\ p(x)-390=-\frac{1}{10}x+\frac{1700}{10} \\ \\ p(x)-390=-\frac{1}{10}x+170 \\ \\ p(x)=-\frac{1}{10}x+170+390 \\ \\ \\ \\ p(x)=-\frac{1}{10}x+560 \end{gathered}\)Then, the function representing the demand p(x) is:

In major league baseball, a no-hitter is a game in which a pitcher, or pitchers, doesn't give up any hits throughout the game. No-hitters occur at a rate of about three per season. Assume that the duration of time between no-hitters is exponential. What is the probability that an entire season elapses with a single no-hitter? If an entire season elapses without any no-hitters, what is the probability that there are no no-hitters in the following season? What is the probability that there are more than 3 no-hitters in a single season?
Using the Poisson distribution, it is found that:
There is a 0.0498 = 4.98% probability that an entire season elapses with a single no-hitter.If an entire season elapses without any no-hitters, there is a 0.0498 = 4.98% probability that there are no no-hitters in the following season.There is a 0.3528 = 35.28% probability that there are more than 3 no-hitters in a single season.What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
\(P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}\)
The parameters are:
x is the number of successese = 2.71828 is the Euler number\(\mu\) is the mean in the given interval.The average rate is of 3 no-hitters per season, hence:
\(\mu = 3\).
The probability that an entire season elapses with a single no-hitter is P(X = 0), hence:
\(P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}\)
\(P(X = 0) = \frac{e^{-3}3^{0}}{(0)!} = 0.0498\)
There is a 0.0498 = 4.98% probability that an entire season elapses with a single no-hitter.
Seasons are independent, hence:
If an entire season elapses without any no-hitters, there is a 0.0498 = 4.98% probability that there are no no-hitters in the following season.
The probability that there are more than 3 no-hitters in a single season is P(X > 3) given as follows:
\(P(X > 3) = 1 - P(X \leq 3)\)
In which:
\(P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)\)
Then:
\(P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}\)
\(P(X = 0) = \frac{e^{-3}3^{0}}{(0)!} = 0.0498\)
\(P(X = 1) = \frac{e^{-3}3^{1}}{(1)!} = 0.1494\)
\(P(X = 2) = \frac{e^{-3}3^{2}}{(2)!} = 0.2240\)
\(P(X = 3) = \frac{e^{-3}3^{3}}{(3)!} = 0.2240\)
Then:
\(P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0498 + 0.1494 + 0.2240 + 0.2240 = 0.6472\)
\(P(X > 3) = 1 - P(X \leq 3) = 1 - 0.6472 = 0.3528\)
There is a 0.3528 = 35.28% probability that there are more than 3 no-hitters in a single season.

29. Assertion :7√5, √2+21 are the irrational number. Reason: every integer is an rational number 30.
The assertion is true. Both 7√5 and √2 + 21 are irrational numbers because they cannot be expressed as fractions.
The assertion is true. Both 7√5 and √2 + 21 are irrational numbers.
An irrational number is defined as a number that cannot be expressed as a fraction of two integers and has an infinite non-repeating decimal representation.
In the case of 7√5, the square root of 5 is an irrational number because it cannot be expressed as a fraction. Multiplying it by 7 does not change its irrational nature.
Similarly, √2 is also an irrational number because the square root of 2 cannot be expressed as a fraction. Adding 21 to √2 does not alter its irrationality.
The reason provided, that every integer is a rational number, is not relevant to the given assertion. While it is true that every integer is a rational number because it can be expressed as a fraction (e.g., 3 can be written as 3/1), it does not contradict the fact that 7√5 and √2 + 21 are irrational numbers.
In conclusion, the assertion is valid, and both 7√5 and √2 + 21 are irrational numbers.

Rewrite the parametric equations in Cartesian form: X(t) = -3sin t, y(t) = 3 cos t
Answer:
\(( \frac{x}{3} ) {}^{2} + ( \frac{y}{3}) {}^{2} = 1\)
or x² +y²= 9
Step-by-step explanation:
In Cartesian form, the equation is expressed only in terms of y and x.
x= -3sin(t) -----(1)
y= 3cos(t) -----(2)
I've written x instead of x(t) as in the later part of the working, we will be having an equation of only x and y, thus x will no longer be a function of t. This applies to equation 2, where I have replaced y(t) with y.
Relating sine to cosine:
sin²(t) +cos²(t)= 1
[sin(t)]² +[cos(t)]²= 1 -----(3)
From (1):
\( \frac{x}{ - 3} = \sin(t) \)
\( \sin(t) = - \frac{x}{3} \) -----(3)
From (2):
\( \frac{y}{3} = \cos(t) \)
\( \cos(t) = \frac{y}{3} \) -----(4)
Substitute (4) &(5) into (3):
\(( - \frac{x}{3} )^{2} + ( \frac{y}{3}) {}^{2} = 1\)
\(( \frac{x}{3} ) {}^{2} + ( \frac{y}{3} ) {}^{2} = 1\)
The steps below are optional as the above is already considered to be the Cartesian form.
\( \frac{ {x}^{2} }{9} + \frac{y {}^{2} }{9} = 1\)
Multiplying both sides by 9:
x² +y²= 9
