P(sum of 8 | sum > 7) = 2/36 = 1/18
So the probability of rolling a sum of 8 given that the sum is greater than 7 is 1/18 or approximately 0.056.
How is probability determined?We must first ascertain the total number of outcomes where the sum is larger than 7 in order to calculate the likelihood that the sum of two fair dice will be 8.
A sum larger than 7 can only result in the following outcomes: (2,6), (3,5), (4,4), (5,3), and (6,2). As there are six alternative outcomes for each die roll, there are 36 permutations in which these five events can occur.
We must now count the number of these 36 outcomes that have a sum of 8. There are just two outcomes that could satisfy this requirement: (2,6) and (3,5). Hence, provided that the sum is more than 7, the following is the likelihood of rolling an 8:

You create a masterpiece in your art studio and it is selected for an art exhibition. Your painting is 70 inches by 100 inches, and you choose framing that costs $4.95 per yard. Find the cost of framing.
The cost of framing for the masterpiece is $46.73.
How to calculate thisTo calculate the cost, we need to first determine the perimeter of the artwork.
Given the dimensions of the artwork, the perimeter is 100 + 100 + 70 + 70 = 340 inches.
The cost of framing is $4.95 per yard, so we need to convert the perimeter to yards.
To do this, we divide the perimeter by 36 inches since 1 yard equals 36 inches.
Thus, 340 inches divided by 36 inches equals 9.44 yards.
Therefore, the cost of framing the artwork will be 9.44 yards multiplied by $4.95 per yard, which equals $46.73.

Hence, a 93% confidence range for the actual proportional difference between the two populations equation (represented by the two samples) is between -0.086 and 0.142.
What is the equation?A mathematical equation connects two statements with the equals sign (=), which stands for equivalence. The equivalence of two mathematical propositions is established by a mathematical assertion that is utilized in algebraic equations. For instance, the equal sign separates the numbers 3x + 5 and 14 in equation 3x + 5 = 14. Use a mathematical formula to understand the relationship between the two sentences written on opposite sides of a letter. Usually, the program's particular logo matches it. A good example is 2x - 4 = 2.
For the initial example:
Sample proportion: 0.649 (p1 = 24/37)
Standard deviation SE1 is equal to
[tex]\sqrt{(p^1*(1-p^1))} /n1=\sqrt{(0.649*(1-0.649))/37)0.087}[/tex]
Regarding the second example:
P2 = 54/87 0.621 is the sample proportion.
The standard deviation SE2 is equal to
[tex]\sqrt{(p^2*(1-p^2))} /n2=\sqrt{(0.621*(1-0.621))/87)0.72}[/tex]
The crucial value for a 93% confidence interval has to be calculated next. We may use the conventional normal distribution and large sample size to obtain the z-value that represents the center 93% of the distribution:
[tex]1.812z=invNorm(\frac{1+0.93}{2} )[/tex]
We can finally determine the confidence interval:
CI is equal to (p1-p2) z*sqrt(SE12 + SE22)
CI is calculated as (0.649 - 0.621) 1.812*sqrt(0.0872 + 0.0722)
CI = 0.028 ± 0.114
CI = (−0.086, 0.142)
The real proportional difference between the two populations (represented by the two samples) thus lies between -0.086 and 0.142, with a 93% confidence interval.

Here's a playground for a school of 360 children in Springfield.
1. The fence around the playground costs 90 dollars per 50-foot roll. Laying the grass across the area costs 400 dollars per 500 square feet. How much did the fencing and grass for this playground cost to build?
2. How many kids per square yard can Springfield's playground hold?
3. There's a new playground going up in nearby Wintermeadow. Wintermeadow has a budget about 3 times greater than Springfield's. Recommend a playground shape and size that would fit Wintermeadow's budget and hold at least 3 times as many kids as Springfield's playground at the same density of kids per square yard. How many kids can your playground hold?
1. The fencing and grass for this playground cost $16,360.
2. Springfield's playground can hold approximately 800 kids at a density of 25 square feet per child.
3. We can recommend a rectangular playground measuring approximately 166 yards by 40 yards, with a total area of 6,666.67 square yards. This playground should cost $49,200 for the fencing and grass.
How did we arrive at these values?1. To calculate the cost of the fencing and grass, we first need to know the dimensions of the playground. Let's assume that the playground is a rectangular shape measuring 100 feet by 200 feet, for a total area of 20,000 square feet.
To determine the cost of the fence, we need to know how many rolls of fencing are required. Each roll is 50 feet long, so we need four rolls to fence the perimeter of the playground (100 + 100 + 200 + 200 = 600 feet / 50 = 12 rolls, but we can't buy half a roll, so we round up to four rolls). Therefore, the cost of the fence is:
4 rolls x $90/roll = $360
To determine the cost of the grass, we need to know how many square feet of grass we need to cover the playground. Since each roll of grass covers 500 square feet, we need:
20,000 sq ft / 500 sq ft per roll = 40 rolls of grass
Therefore, the cost of the grass is:
40 rolls x $400/roll = $16,000
Adding the cost of the fence and the grass, we get the total cost:
$360 + $16,000 = $16,360
So the fencing and grass for this playground cost $16,360.
2. To calculate how many kids per square yard the playground can hold, we need to know the area of the playground in square yards. There are 9 square feet in a square yard, so the playground measures:
20,000 sq ft / 9 sq ft per sq yd = 2,222.22 sq yds
Assuming that each child requires 25 square feet of space to play, we can calculate how many kids can fit on the playground:
2,222.22 sq yds x (9 sq ft per sq yd / 25 sq ft per child) = 800 kids
Therefore, Springfield's playground can hold approximately 800 kids at a density of 25 square feet per child.
3. To recommend a playground shape and size that would fit Wintermeadow's budget and hold at least 3 times as many kids as Springfield's playground at the same density of kids per square yard, we first need to know Wintermeadow's budget.
Let's assume that Springfield's budget is $50,000, so Wintermeadow's budget is $150,000.
To determine the size of the new playground, we can start by calculating the cost of the fencing and grass for Springfield's playground per square yard:
$16,360 / 2,222.22 sq yds = $7.38 per sq yd
We can then use this cost to estimate the size of the new playground. Let's assume that the new playground will also be rectangular, and that we want it to hold at least 3 times as many kids as Springfield's playground, or 2,400 kids. Using the same density of 25 square feet per child, we need:
2,400 kids x 25 sq ft per child = 60,000 sq ft
Since there are 9 square feet in a square yard, this is:
60,000 sq ft / 9 sq ft per sq yd = 6,666.67 sq yds
Multiplying this area by the cost per square yard, we get the cost of the fencing and grass for the new playground:
6,666.67 sq yds x $7.38 per sq yd = $49,200
Therefore, we can recommend a rectangular playground measuring approximately 166 yards by 40 yards, with a total area of 6,666.67 square yards. This playground should cost $49,200 for the fencing and grass.

b) On average, about 240 people visit a local food pantry every day in search of groceries. On an extremely cold day, visitors to the food pantry can be 175% of the average amount. About how many visitors might go to the food pantry on an extremely cold day?
About 420 visitors might go to the food pantry on an extremely cold day
What is the percentage?
Percentage refers to a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%". For example, if 30 out of 100 students in a class are girls, the percentage of girls in the class is 30%. Percentages are commonly used in many fields, such as finance, statistics, and science, to express proportions, rates, and changes over time.
The problem states that on average, about 240 people visit the food pantry every day in search of groceries. To find out how many visitors might go to the food pantry on an extremely cold day, we need to use the given percentage increase.
The phrase "175% of the average amount" means that we need to find 175% of 240, which is the same as multiplying 240 by 1.75 (since 175% is the same as 1.75 as a decimal). Using the multiplication, we get:
175% of 240 = (175/100) * 240 = 420
So, on an extremely cold day, the number of visitors to the food pantry might be around 420.
Therefore, about 420 visitors might go to the food pantry on an extremely cold day.

no solution
x = 6 and x=10
x = -5 and x =5
x= -1 and x=-4
Answer:
x = -5 and x =5
Step-by-step explanation:
However, we notice that the solutions -5 and 5 satisfy the original equation in case 2, because |-6(-5)| = 30 and |-6(5)| = 30 is true. Therefore, the two solutions that satisfy the original equation in both cases are x = 5 and x = -5.

Maria and Connor are doing yard work for a neighbor. They make a total of $595.54. Since Connor works more hours than Maria, Connor gets 69% of the money. About how much (in whole
dollars) does Connor make?
Connor makes about
Answer: Since Connor gets 69% of the money, Maria gets the remaining 31%:
100% - 69% = 31%
Let's first find out how much money Maria makes:
Maria's share = 31% of $595.54
Maria's share = 0.31 x $595.54
Maria's share = $184.61
Now, to find out how much Connor makes, we can subtract Maria's share from the total:
Connor's share = Total - Maria's share
Connor's share = $595.54 - $184.61
Connor's share = $410.93
Therefore, Connor makes about $410.93 (rounded to the nearest dollar).

We can write the equations in matrix form as follows to answer the simultaneous equations 1x + 4y = 9 and 2x - 3y = 7 using the matrix method:
Then, on the left side of the equation, we can locate the inverse of the coefficient matrix:
| 1 4 |^-1 = 1/(-11) | -3 -4 |
|-2 -1 |
When we multiply both sides of the equation by the coefficient matrix's inverse, we obtain:
| x | | 1 4 |^-1 | 9 |
| x | | -3/11 -4/11 | | 9 |
| y | = | -2/11 -1/11 | x | 7 |
If we simplify, we get:
x = (-3/11)*9 + (-4/11)*7 = -1
y = (-2/11)
*9 + (-1/11)
*7 = 1
Thus, using the matrix technique, the solutions to the simultaneous equations are x = -1 and y = 1.

Cai and his children went into a movie theater and will buy bags of popcorn and pretzels. He must buy a maximum of 7 bags of popcorn and pretzels altogether. Write an inequality that would represent the possible values for the number of bags of popcorn purchased, � b, and the number of pretzels purchased, � . p.
Answer: b + p ≤ 7
Step-by-step explanation:
Let's use b to represent the number of bags of popcorn purchased and p to represent the number of bags of pretzels purchased.
Since Cai can buy a maximum of 7 bags of popcorn and pretzels altogether, we know that:
b + p ≤ 7
This is the inequality that represents the possible values for the number of bags of popcorn purchased (b) and the number of bags of pretzels purchased (p).
Is this a planar graph? If so, draw a planar representation of the graph. If not,
explain why it is not planar.
Each of these vertices, which together make up a full graph with five equation vertices, can be seen to be linked to the other four vertices in the subgraph.
What is equation?A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A formal statement that proves the equality of two calculations is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two phrases that are inscribed on opposite sides of a letter. Frequently, the logo and indeed the particular software are identical. like in 2x - 4 = 2, for example.
This graph is not planar because it has a subgraph that is isomorphic to the whole, non-planar graph with five vertices (K5).
K5 is a non-planar graph as it cannot be represented in a planar manner on a 2D plane without at least five crossing edges. This graph is also non-planar since K5 is a subgraph of it.
We may determine five vertices that make up a whole subgraph, for instance, vertices 1, 2, 3, 5, and 6, to demonstrate that this graph has K5 as a subgraph. Each of these vertices, which together make up a full graph with five vertices, can be seen to be linked to the other four vertices in the subgraph.

jack has 375in of sand to pour into a rectangular prism the base of the prism is 5 by 7 and the hight is 9 will the sand fit explain why or why not
Answer:
Yes, it will fit.
Step-by-step explanation:
To determine whether 375 cubic inches of sand will fit into the given rectangular prism, we need to calculate the volume of the prism and compare it to the amount of sand.
The formula for the volume of a rectangular prism is:
Volume = Base x Height x Width
In this case, the base of the prism is 5 by 7 inches, so the area of the base is:
Area of Base = 5 inches x 7 inches = 35 square inches
The height of the prism is 9 inches. Therefore, the volume of the prism is:
Volume = Base x Height = 35 square inches x 9 inches = 315 cubic inches
So, the volume of the prism is 315 cubic inches, which is less than the amount of sand Jack has (375 cubic inches). Therefore, all of the sand will fit inside the rectangular prism with room to spare.
In summary, the sand will fit inside the rectangular prism because the volume of the prism is greater than the amount of sand Jack has.
solve for x. 4(x+56.5)=30x-112
Answer:
x = 13
Step-by-step explanation:
Let's simplify and solve for x:
4(x+56.5) = 30x - 112
First, we distribute the 4:
4x + 4(56.5) = 30x - 112
Simplifying the expression:
4x + 226 = 30x - 112
Now we move all the x terms to one side and all the constants to the other:
226 + 112 = 30x - 4x
338 = 26x
Finally, we solve for x by dividing both sides by 26:
x = 13
Therefore, the solution to the equation 4(x+56.5)=30x-112 is x = 13.
Answer:
x=9.94
Step-by-step explanation:
4x + 226 = 30x - 112
226+112 = 34x
338 = 34x
338/34=x
9.94=x
