You want to order carpet for an area in your house. The room measures 12 feet by 10 feet. Remember, Area = Length × Width.
If each square yard of carpet costs $30.25, how much will the carpet cost you? Use your answer from the previous question to answer this question.
a.
$1,210
b.
$393.25
c.
$11,979
d.
$32,670
Answers
Answer:
403.33
Step-by-step explanation:
The price is in square yd not feet so change ft to yds
3 ft = 1 yd
12 ft = 12/3 = 4 yds
10 ft = 10/3 yds
A = l * w = 4 * 10/3 = 40/3 yd^2 = 13 1/3 yd ^2
Now multiply by the price per yd^2
13 1/3 yd^2 * 30.25 = 403.333333

Answers
Answer:
The answer is
[tex]f( - 4) = - 56[/tex]Step-by-step explanation:
[tex]f(x) = - 3 {x}^{2} - 8 \\ [/tex]
To find f(-4) , substitute the value of x that's - 4 into f(x). That is for every x in f(x) , replace it with - 4
We have
[tex]f( - 4) = - 3 ({ - 4})^{2} - 8 \\ = - 3(16) - 8 \\ = - 48 - 8 \: \: \: \: \: [/tex]
We have the final answer as

Which point lies on the line with a slope of m=2/3 that passes through the point (-3,-2)?
A. (3,4)
B. (5,7)
C. (-8,-4)
D. (-9,-6)
Answers
Answer:
D. (-9,-6)
Step-by-step explanation:
Use the given slope and point to solve for y using the point-slope equation.
y-y = m(x - x)
m= 2/3 (-3, -2)
y + 2 = 2/3(x + 3)
y + 2 = 2/3x + 2
y = 2/3x
Then plug in the x's in the points that you can choose from. If the y equals the y in the given point that is the answer.
( 3,4) y = 2/3(3) = 2
( 5,7) y = 2/3(5) = 10/3
( -8, -4) y = 2/3(-8) = - 16/3
( -9, -6) y = 2/3(-9) = -6
Suppose θ is an angle in the first quadrant and cos(θ) = 1/2. What is the value of sin(θ)?
A. 1/2
B. √3/2
C. 3/5
D. -√3/3
Answers
Answer:
B. [tex] \frac{\sqrt3}{2}[/tex]
Step-by-step explanation:
Since θ is in the first quadrant, both sin(θ) and cos(θ) are positive.
Using the Pythagorean identity,[tex]sin^2(θ) + cos^2(θ) = 1 [/tex]
we can solve for sin(θ) as follows:
[tex]sin^2(θ) + (\frac{1}{2})^2 = 1[/tex]
[tex]sin^2(θ) +\frac{1}{4}=1[/tex]
[tex]sin^2(θ) =1-\frac{1}{4}[/tex]
[tex]sin^2(θ) =\frac{3}{4}[/tex]
[tex]sin(θ) = \sqrt{\frac{3}{4}} = \frac{\sqrt3}{2}[/tex]
Therefore, the value of sin(θ) is[tex] \frac{\sqrt3}{2}[/tex]
Answer:
B
Step-by-step explanation:
given
cosΘ = [tex]\frac{1}{2}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]
this is a right triangle with hypotenuse = 2 and a leg = 1
using Pythagoras' identity to find the third side o , the opposite side, then
o² + 1² = 2²
o² + 1 = 4 ( subtract 1 from both sides )
o² = 3 ( take square root of both sides )
0 = [tex]\sqrt{3}[/tex]
Then
sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex]

Devan scored 7. from the given information, we know that a +ve score means the amount by which the player failed to beat the record
Let the record be x m
Hence, the distance Devan threw = record - 7
Devan's distance = x - 7 m
Similarly, we can see that Joel's score is 15 less than the record
Hence, the distance covered by Joel's discus = record - 15
Joel's Distance = x - 15 m
We are told that the distance covered by Greg's discus is the opposite of Devan
That means that since devan scored 7 , Greg scored the opposite of 7 i.e:
-7
We have been told that a negative score denotes the distance covered by the discus after breaking the record
Hence, the distance covered by Greg's discuss = record + 7
Greg's Distance = x + 7 m
a) Difference between Greg's and Joel's distances
Greg's Distance - Joel's Distance
(x + 7) - (x - 15)
x + 7 - x + 15 = 22 m
b) Leo's score was 4 less than Greg's Score:
Hence, Leo's score = Greg's score - 4
Leo's Score = (x + 7) - 4
Leo's score = x + 3
Here, we can see that Leo broke the record by 3 points
c) Ordering the scores in Descending order:
We know that Greg has the highest score and Leo is lacking by a few points, then comes Devan and Joel has the least score
(x + 7) > (x + 3) > (x -7) > (x - 15)
4. We know that any non-zero score is the deviation from the record score.
When the scores are given as integers, the absolute value of the score will tell us the deviation from the record score
3. In determining food spending, it was found that the average meal in Albany is normally distributed, with a mean of $40 and a standard deviation of $4. Find the following: P(X < 40), P(38 < X < 42), P(X > 35), P(X > 51). Find a meal cost which happen to be cheaper than 10% of the meals based on a given data. Find a meal cost which happen to be in the 5% of the most expensive based on a given data. Find a meal costs which happen to be 40% symmetrically around the mean value based on a given data.
Answers
Answer:
a) P(X < 40) = 0.5
b) P(38 < X < 42) = 0.69143
c) P(X > 35) = 0.89435
d) P(X > 51) = 0.0029798
e) Find a meal cost which happen to be cheaper than 10% of the meals based on a given data. = $34.872
f) Find a meal cost which happen to be in the 5% of the most expensive based on a given data = $33.42
g) Find a meal costs which happen to be 40% symmetrically around the mean value based on a given data. = $38.988
Step-by-step explanation:
Z score formula = Z score = x - μ/σ
Mean = $40
Standard deviation = $4
a) P(X < 40)
Z score = x - μ/σ
= 40 - 40/4
= 0
Determining the Probability value from Z-Table:
P(X < 40) = 0.5
b) P(38 < X < 42)
For X = 38
Z score = x - μ/σ
= 38 - 40/4
= -0.5
Determining the Probability value from Z-Table:
P(X = 38) = 0.30854
For X = 42
Z score = x - μ/σ
= 42 - 40/4
= 4
Determining the Probability value from Z-Table:
P(x = 42) = 0.99997
Hence, P(38 < X < 42)
P(X = 42) - P(X = 38)
0.99997 - 0.30854
= 0.69143
c) P(X > 35)
Z score = x - μ/σ
= 35 - 40/4
= -1.25
Determining the Probability value from Z-Table:
P( X < 35) = 0.10565
P( X > 35) = 1 - P(X < 35)
1 - 0.10565
= 0.89435
d) P(X > 51)
Z score = x - μ/σ
= 51 - 40/4
= 2.75
Determining the Probability value from Z-Table:
P( X < 51) = 0.99702
P(X > 51) = 1 - P(X < 51)
= 1 - 0.99702
= 0.0029798
e) Find a meal cost which happen to be cheaper than 10% of the meals based on a given data.
z score for 10th percentile = -1.282
Z score formula = Z score = x - μ/σ
Mean = $40
-1.282 = x - 40/4
-1.282 × 4 = x - 40
-5.128 + 40 = x
$34.872
The meal cost which happen to be cheaper than 10% of the meals based on a given data is $34.872
f) Find a meal cost which happen to be in the 5% of the most expensive based on a given data
Z score for 5th percentile = -1.645
Z score formula = Z score = x - μ/σ
Mean = $40
-1.645 = x - 40/4
-1.645 × 4 = x - 40
-6.58 + 40 = x
$33.42
The meal cost which happen to be in the 5% of the most expensive based on a given data is $33.42
g) Find a meal costs which happen to be 40% symmetrically around the mean value based on a given data.
Z score for 40th percentile = -0.253
Z score formula = Z score = x - μ/σ
Mean = $40
-0.253 = x - 40/4
-0.253 × 4 = x - 40
-1.012 + 40 = x
$38.988

When taking an exam, some students quickly answer all the questions they know how to do. If they go back and revise their answers, they start second guessing themselves and end up changing their choice from the correct answer to an incorrect one. Other students work through the exam very slowly - they think things very thoroughly, revise their answers several times, and carefully make sure they have not missed anything. In a class where we have both these types of students together, the correlation between the amount of time spent on an exam and their grade should be: _____________
a. Positive and fairly strong
b. Negative and fairly strong
c. Fairly weak
Answers
Answer:
c. Fairly weak
Step-by-step explanation:
From the given question:
We can deduce that the correlation between those two criteria is fairly weak. This is because the first set of students who initially answered the question started second-guessing themselves, making them unsure about their decision when picking the right answers. They eventually ended up choosing the wrong answers when changing it.
Negative and fairly strong correlation exist between the amount of time spent on an exam and their grade.
What is negative correlation?Negative correlation occurs between two variables in which as one variable increases the other decreases.
The first group finished very fast but recheck and picked wrong answer, although they were fast but they eventually had a wrong answer this is a negative correlation.The second group worked slowly and ended up getting good mark this is a Fairly strong correction because there is a result for the time used.Therefore, negative and fairly strong exist between time of exam and their grade.

The residents of a city voted on whether to raise property taxes. The ratio of yes to no votes was 4 to 7. If there were 3496 yes votes, whats was the total number of votes.
Answers
Answer:
9614
Step-by-step explanation:
Let us take 4 in the ratio as 4 units.
If 4 units means 3496, let us first find how many votes 1 unit is made up of.
3496/4=874 (/ means divide sign. If you are writing the equations out, do remember to change it to the actual divide sign. Sorry for the inconvenience)
Let us find how what is the total number of units now!
4+7=11
Now that we found out the total number of units, and how many votes is each unit made out of, it is time to find the final answer by multiplying each other.

What is the median of the sample 5, 5, 11, 9, 8, 5, 8 ?
Answers
Answer:
8.
Step-by-step explanation:
The median of any set of numbers is the middle-most number of the set when ordered from least to greatest. Ordering this set from least to greatest, we get "5, 5, 5, 8, 8, 9, 11." There are 7 numbers here, so the middle-most number is the 4th number, or 8. In the case that you have an even amount of numbers to choose, you take the average of the two middle-most numbers to find your median.
The median of the sample is the middle value of the data set which is number 8.
What is medians of the data set?Median of the data set is the middle value of the data when data is arranged in the increasing order or decreasing order.
The data of the sample given in the problem is,
[tex]5, 5, 11, 9, 8, 5, 8[/tex]
Arrange this data in the increasing order.
[tex]5, 5, 5, 8, 8, 9, 11[/tex]
There is total 7 observation in the above data. The middle value will be the fourth number observation, which is 8.
Hence, the median of the sample is the middle value of the data set which is number 8.
