When carpet sells for $4 per square foot and will cost you $616 to carpet your rectangular room, if you room is 14 feet long then the width is 11 feet
Given,
The cost of Carpet per square foot = $4
Total cost of the carpet = $616
We know
Area of the rectangle = Length × Width
Length = 14 feet
Consider the width of the rectangular room as x
Then the area of the room = 14x
Total cost of carpet = Area of the rectangular room× Cost of carpet per foot
Substitute the values
14x×4=616
14x=154
x=11 feet
Hence, When carpet sells for $4 per square foot and will cost you $616 to carpet your rectangular room, if you room is 14 feet long then the width is 11 feet

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
Hence, the answer is $31.58.

4. A student has these scores on their assignments. The teacher is considering droppi
a lowest score. What effect does eliminating the lowest value, 0, from the data set
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.

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)

The 6th term of the geometric sequence is of -4096.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
For this problem, we have that:
The first term is [tex]a_1 = 4[/tex].[tex]a_n = -4a_{n - 1}[/tex], hence the common ratio is q = -4.Thus the 6th term of the sequence is found as follows:

What do we mean by line segment?A line segment is a section of a straight line that is constrained by two distinct end points and contains every peak on the line between them. The Euclidean distance between the endpoints of a line segment determines its length. A closed line segment contains both endpoints, whereas an open line segment does not; a half-open line segment contains only one endpoint. In real life, a line segment can be represented by a ruler, a pencil, or a stick. The sun's rays are an illustration of a ray. The sun is the origin of the sun's rays, but there is no endpoint. A line segment is a perfect example of a classroom floor.Therefore, (D) the floor of a classroom is a perfect example of a line segment.

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

Step-by-step explanation:
Given that m∠ABC = 143°, find m∠ABD and m∠DBC.
Answer:
m<ABD = 24°
m<DBC = 119°
Step-by-step explanation:
m<ABD + m<DBC = m<ABC
2x - 40 + 3x + 23 = 143
5x - 17 = 143
5x = 160
x = 32
m<ABD = 2x - 40 = 2(32) - 40 = 24
m<ABD = 24°
m<DBC = 3x + 23 = 3(32) + 23 = 119
m<DBC = 119°
