The term that best represents the intersection of two pages of an open book is point.
What is intersection?A third item made up of everything that is simultaneously contained in all of the other things is called an intersection of two or more objects in mathematics. In Euclidean geometry, for instance, the intersection of two lines in a plane that are not parallel is where they come together. More broadly, the set of elements that are a part of all of the sets is what is meant by the intersection of sets in set theory. The items being considered do not need to be in a shared space, unlike the Euclidean concept.
A point is the most frequent shape for an intersection in plane geometry, while there are other shapes that can be used as well. An intersection is an item of lesser dimension that is incident to each in incidence geometry, which is typically applied to flats.

Evaluate each expression so the equation is 8b-a and a=4 and b=6
Answer: 44
Step-by-step explanation: basically replace b with 6 and a with 4 in the expression 8b-a, which turns out to be 8(6)-(4). We're subtracting 4 from the product of 8(6), which is 48. 48-4 = 44

C 0
D -81
E -45
Answer:
no answer
Perhaps: E -45
Step-by-step explanation:
(2x + 4) = 14
2x + 4 = 14
2x = 10
x = 5
This equation has only 1 solution.
There cannot be the product of the "solutions" when there is only 1 solution.

|2x +4| = 14
A 45
B 81
C 0
D -81
E -45
|2x + 4| = 14
2x + 4 = 14 or 2x + 4 = -14
2x = 10 or 2x = -18
x = 5 or x = -9
The product of 5 and -9 = -45

Fatoumata has a collection of 280 coins. How many coins represent 20% of her
collection?
Divide/scale down to solve for the missing percent.
The coins that represent the 20 5 of her coins that is 280 are 56 coins.
We know that:
Fatoumata has a collection of 280 coins.
Now, we need to tell how many coins will be its 20 %.
For this we will calculate 20 percent of 280
So, number of coins = N will be:
N = 20 % of 280
N = 20 % × 280
N = 20 / 100 × 280
N = 2 × 28
N = 56 coins
Therefore, we get that, the coins that represent the 20 5 of her coins that is 280 are 56 coins.

The value of r is 11°
How to determine the valueFrom the information given, we have that;
52°(4r-6)⁰Both angles are complementary angles.
It is important to note that complementary angles sum up to 90 degrees
Then, we have;
52 ° + 4r - 6° = 90°
collect like terms
4r + 46° = 90 °
4r = 90 - 46
4r = 44

Joe's employer will reimburse him $0.17 per mile driven. If Joe drives 185.74 miles on a business trip, what is his mileage reimbursement? Round your answer to the nearest cent.
how do you not know how to do this
0.17 times 185 = $136.9 or $137
(0.74 is not 1 mile)
Answer:
$31.58
Step-by-step explanation:
Reimburse for 1 mile,
→ $0.17
Then reimbursement for 185.74 miles,
→ 185.74 × 0.17
→ 31.5758
→ $31.58

9. Use the graph of the sequence to answer the parts.
a. Is the sequence arithmetic, geometric, or neither Explain.
b. Write a recursive formula for the sequence.
c. Write an explicit formula for the sequence.
The recursive formula for the sequence is T(n+1) = Tn - 3 where T1 = 19 and the explicit formula for the sequence is Tn = 22 - 3n
a. Is the sequence arithmetic, geometric, or neitherOn the given graph, we have the following points
19, 16, 13, 10, 7
These points represent the nth term of the sequence
See that the points have a common difference of -3
Hence, the sequence is an arithmetic sequence
b. Write a recursive formula for the sequence.In (a), we have
T1 = 19
d = -3
So, we have
T2 = T1 + d
This gives
T2 = T1 - 3
Express 2 as 1 + 1
So, we have
T(1+1) = T1 - 3
Express 1 as n
So, we have
T(n+1) = Tn - 3
Hence, the recursive formula for the sequence is T(n+1) = Tn - 3 where T1 = 19
c. Write an explicit formula for the sequence.In (a), we have
T1 = 19
d = -3
So, we have
Tn = T1 + (n - 1)d
This gives
Tn = 19 + (n - 1) * -3
Evaluate
Tn = 19 + 3 - 3n
Evaluate the sum
Tn = 22 - 3n
Hence, the explicit formula for the sequence is Tn = 22 - 3n

300 teenagers went to the zoo.
How to find the how many teenagers went to the zoo?given that
Tickets to the zoo cost $4 for children.
Tickets to the zoo cost $5 for teenagers.
Tickets to the zoo cost $6 for adults.
1200 people come to the zoo every day.
on a certian day, the total revenue at the zoo was $5300.
Let the number of adults be x.
The number of teenagers be y.
and the number of children that went to the zoo 8y/3.
Consider the question
1200 people come to the zoo every day.
x + y + 8y/3 = 1200
now, take L.C.M between y and 8y/3
[tex]x + \frac{(3y + 8y)}{3} = 1200 \\ x + \frac{11y}{3} = 1200[/tex]
now multiply with 3 to this equation.
3x + 11y = 3600 .......................(1)
tickets to the zoo cost $4 for children, $5 for teenagers and $6 for adults.
according to the question
6x + 5y + 32y/3 = 5300
Now take the L.C.M between 5y and 32y/3
6x + 47y/3 = 5300
now multiply with 3 to this equation.
18x + 47y = 15900 ...................(2)
now, multiply equation (1) with 6
18x + 66y = 21600 .....................(3)
now, subtract equation (1) in equation (2)
(18x - 18x) + (66y - 47y) = (21600 - 15900)
19y = 5700
y = 5700/19
y = 300

suppose you have two bags of marbles that are in a box. bag 1 contains 7 white marbles, 6 black marbles, and 3 gold marbles. bag 2 contains 4 white marbles, 5 black marbles, and 15 gold marbles. the probability of grabbing the bag 1 from the box is twice the probability of grabbing the bag 2. if you close your eyes, grab a bag from the box, and then grab a marble from that bag, what is the probability that it is gold?
The probability that it is gold is (1/3).
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 statement 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 likelihood that an event will occur increases with its probability. If two events are mutually exclusive, then there is a 0 percent chance that they will both happen at the exact moment. Two events are said to be mutually exclusive if they share no elements (their intersection is the empty set). Consequently, P(A∩B)=0.
Let A be the event that a gold marble is picked.
Let B₁ and B₂ be the event that the first bag is chosen and the second bag is chosen respectively.
Given: P (B₁ ) = 2.P(B₂)
Also, P(B₁) + P(B₂) = 1
∴ 2P(B₂) + P(B₂) =1
3P(B₂) = 1
P(B₂) = 1/3 and P(B₁) = 2/3
Now
P(A)
= P(A∩(B₁∪B₂))
= P[(A∩B₁)∪(A∩B₂)]
Probability adds up because the events are mutually exclusive
= P(A∩B₁) + P(A∩B₂)
= P(B₁). P(A/B₁) + P(B₂). P(A/B₂)
= (2/3)×(3/16) + (1/3)×(15/24)
= (1/3)

4. A student has these scores on their assignments. The teacher is considering droppi

have on the mean and median?
0, 40, 60, 70, 75, 80, 85, 95, 95, 100
We can conclude that the value of both mean and median increases when we remove the lowest value, 0, from the data set.
What do we mean by mean and median?The mean is the average of a set of values in mathematics and statistics. The mean can be calculated in a variety of ways, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean.The median is the number in the middle of a sorted list of numbers, and it is more descriptive of the data set than the average. When there are outliers in the sequence that could skew the average of the values, the median is sometimes used instead of the mean.(1) First, we have to find the value of the mean and median with the value of 0.
(A) Mean: Sum of all values/Number of terms
= 700/10= 70(B) Median: If the number is an even number, add the two middles and divide by 2.
= 75 + 80/2= 155/2= 77.5(2) Now, we have to find the value of the mean and median without the value of 0.
(A) Mean: Sum of all values/Number of terms
= 700/9= 77.77(B) Median: If there are an odd number of observations, the number in the middle of the list is the median.
= 5th term from both sides is the middle value= 80Therefore, we can say that the value of both mean and median increases when we remove the lowest value, 0, from the data set.
