Based on the area of Marcellus's lawn, the number of pounds of fertilizer needed for Marcellus's lawn is 4 ¹/₅ pounds
How much fertilizer is needed?In order to fertilize an area of 2 acres, the number of pounds of fertilizer needed is 10 ¹/₂ pounds.
The area of Marcellus's lawn is only 4/5 of an acre however so to find the pounds of fertilizer needed, use direct proportion:
2 acres : 10 ¹/₂ pounds
4/5 acres : x
2x = 8.4
x = 8.4 / 2
x = 4.2 pounds
= 4 ¹/₅ pounds

TechWiz Electronics makes a profit of $35 for each MP3 player sold and $18 for each DVD player sold. Last week, TechWiz sold a combined total of 118 MP3 and DVD players.
Let x be the number of MP3 players TechWiz sold last week. Write an expression for the combined total profit (in dollars) TechWiz made from MP3 and DVD players last week.
total profit (in dollars)
The required expression is 17x + 2124 which represents the combined total profit (in dollars) TechWiz made from MP3 and DVD players last week.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
Let the number of MP3 players TechWiz sold last week would be x.
Here TechWiz Electronics makes a profit of $35 for each MP3 player sold.
Last week, TechWiz sold a combined total of 118 MP3 and DVD players.
As per the condition,
So the required expression for the combined total profit would be:
= 35x + 18(118-x)
= 35x + 2124 - 18x
= 17x + 2124
Hence, the required expression is 17x + 2124 which represents the combined total profit (in dollars) TechWiz made from MP3 and DVD players last week.

A coin marked “0” and “1” is tossed an infinite number of times, the probability of 1 in any toss being equal to p 2 (0, 1). The resulting sequence (outcome) ! is parsed into consecutive blocks of increasing length: 2, 4, 6,..., etc. What is the likelihood that, in infinitely many of these blocks, the first half of the terms are either all 0’s or all 1’s?
It is very less possibilities that the first half of the terms are either all 0's or all 1's.
According to the question, the probability to toss the coins which are marked as 0 or 1 is: 2
And the getting favorable outcomes that is 0 or 1: 1
Therefore, the probability for the given possibility is written as:
P(A) = n(A)/n(S) = 1/2
Hence, for infinite times, it is the half of the possibilities that the first half is either 0 or 1.
What is probability?
Probability can be defined as the outcomes which can be predicted or which can be calculated. It is the ratio of the total number of the favored outcomes to the total number events. The value of the probability is always less than1.

The radius of the large circle would just be the diameter of one of the smaller circles, so 14 inches.
In order to solve this, we will need to find the area of the large circle and subtract the area of two smaller circles.
I'll be using pi as 3.14 for this.
Large Circle:
[tex]A = \pi r^{2}\\A = \pi (14)^{2}\\A = 196\pi \\A = 615.44[/tex]
Smaller Circle:
[tex]A = \pi r^{2}\\A = \pi (7)^{2}\\A = 49\pi \\A = 153.86[/tex]
Now we just simply subtract them.
615.44 - (2 * 153.86)
= 307.72 inches
You might've noticed that is exactly half of the area of the larger circle.
That's because if you halve the radius of a circle, you will get one fourth of original area.
Suppose that you are taking a course that has 4 tests. The first three tests are for 100 points each and the fourth test is for 200 points. To get an B in the course, you must have an average of at least 80 percent on the 4 tests. Your scores on the first 3 tests were
79
,
77
, and
91
. What is the minimum score you need on the fourth test to get an B for the course?.
The minimum score needed on the fourth test to get a B grade for the course is; 153 points.
What is the minimum score required for a B ?It follows from the task content that the first 3 tests attract 100 points each while the fourth test attracts 200 points. On this note, it follows that the total number of points attainable is; 500 points.
To get 80%, one must get; (80/100) × 500 = 400 points.
Hence, the minimum score needed on the fourth test to get a B is; 400 - 79 - 77 - 91 = 153 points.

Given that the owner charges $7 per ticket, every customer receives a brochure that costs the owner $2 for each person and the owner must pay his band $1200.
We are required to find the people must attend for him to break-even.
Break even point is the point at which there is not any profits or losses.
We have to first form the equation for the break even.
Suppose the number of people be x.
Cost to the owner will be 1200+2x.
Revenue will be 7x.
Break even point will be at the point where 7x=1200+2x
7x-2x=1200

Nina is making 4 pans of fudge to serve
after a music recital. For each pan, she needs 2/3
cup of condensed milk.
Draw a diagram to show two different ways that Nina could
measure the condensed milk needed for 4 pans of fudge.
The total number of condensed milk required is 8/3=2 2/3.
The total number of pan is 4
The condensed milk required for each pan is 2/3
The pieces of a whole are how fractions are described in mathematics. One or more objects may make up the whole. When we cut a piece of pizza in real life from the entire pizza, the part represents the percent of the pizza.
The total number of condensed milk is 4. 2/3= 8/3
For first pan let the measuring cup is 1/4 then the condensed milk is measured as
1/4 . 2/3 =1/6
For second pan let the measuring cup is 1/2 , then the condensed milk is measured as
1/2 . 2/3 = 1/3
Hence the total number of condensed milk required is 2 2/3.

What is termed as the disjoint sets?Disjoint sets are the ones in which their intersection results in such a null set. In set theory, we sometimes notice that two sets have no common elements, or that the intersection of a sets is an empty set or null set. This is referred to as a disjoint set. For instance, if we have X = a, b, c and Y = d, e, f, we can say that given 2 sets are disjoint because they have no common elements.For the given condition;
P(E) = P(F) = 0.7
the sum of both will be.
P(E) + P(F) = 1.4
But, we know that probability can never be more than 1.
Thus, there must be some elements which are common in both sets, which makes the set disjoint.
Thus, events E and F are not disjoint events.

A) The cost per pound of meat is $6.
B) Janelle can buy a maximum of 7 pounds

The correct response is D. Janelle buys twice as many pounds of meat as pounds of vegetables.
The number 6 in the equation indicates the number of pounds of meat that Janelle purchases, and the number 3 represents the number of pounds of veggies that she purchases.
This is because in the above equation, x is the cost per pound of meat and y is the cost per pound of vegetables. So it stands to reason that Janelle purchases twice as much meat as veggies.
Choice A is erroneous because x, which is used to indicate the price per pound of beef, might not be equal to 6. Choices B and C are erroneous because it is impossible to predict how many pounds of meat and produce Janelle could purchase without knowing the values of x and y.

Explanation:
P(U and V) = 0 since U and V are mutually exclusive. Such events cannot happen at the same time. Example: flipping a coin to get heads and tails at the same time.
-------
P(U or V) = P(U) + P(V) - P(U and V)

What is slope intercept of line?y=mx+c
where m is the slope.
Firstly we need to find the slope of the line x - 2y = 6 by using slope intercept form, y=mx+c.
-2y=6-x
2y=x-6
y=1/2 x-6
m=1/2 slope of the line x - 2y = 6.
For parallel lines slope will be same.
Now Use y = mx + b and the point (1,-6) to find b, the y-intercept.
-6= (1/2)*1 + b
-6-1/2=b
-13/2=b
y=1/2x-13/2 is the equation of line.
Therefore y=1/2x-13/2 is the line parallel to x + 2y = 6.
