Answer:
16.40-7.80= 8.608.60/16.40×100= 52.43%Answer: 52.4 percent
Step-by-step explanation: So you'd want to subtract 7.80 from 16.40 to get 8.60. Then you'd multiply that by 100 which would give you 860. After you've done that you want to divide 860 by 16.40.
x^2 – 2x – 54 = 0
I need it in completing the square form
Completing the Square:
x^2 - 2x = 54
x^2 - 2x + 1 = 54 + 1
(x-1)^2 = 55
x - 1 = ±[tex]\sqrt{55\\}[/tex]
x = 1 ± [tex]\sqrt{55}[/tex]

If linda has borrowed 8 more books than susan from school library. Richard has borrowed half as many books as Linda has. If Richard has borrowed 17 books from library. How many books has susan borrowed
????????????????????????????
The number of books Susan borrowed is 30 books.
Given that
Richard borrowed 17 books.Richard borrowed half as many as Linda has, so For Linda, it should be 17 × 2 = 38 books.Linda borrowed 8 books more as compared with Susan.So, Susan should borrow books of
= 38 - 8
= 30 books
Therefore we can conclude that The number of books Susan borrowed is 30 books.

Do you expect the difference between the 25th percentile and the median (50th percentile) to be Group of answer choices Larger than the difference between median and 75th percentile. We need to see the actual data to answer this question Smaller than the difference between median and 75th percentile. Equal to the difference between median and 75th percentile.
Answer:
Equal to the difference between median and 75th percentile.
Step-by-step explanation:
xth percentile:
If a measure is said to be in the xth percentile, it means that x% of the measures are smaller than it, and (100-x)% are larger.
Distance between percentiles:
If the difference between two percentiles is the same, the difference between the measures should also be the same.
Median:
The 50th percentile is called median.
In this question:
75th percentile - 50th percentile = 25
50th percentile - 25th percentile = 25
The differences should be equal.

Find the slope of the line that contains the following pair of points: (1, 2), (5,2).
O A. - 1
O B. o
O C. 4
OD. Undefined
Answer:
The answer is 0
Step-by-step explanation:
input into slope formula
The slope of the line is 0.
The correct option is (B).
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Points from the graph (1, 2) and (5, 2).
So, the slope of line
= ( 2- 2) / (5 -1)
= 0 / 4
= 0
Hence, the slope of line is 0.

The mean is usually the preferred measure of central tendency, but there are specific situations in which it is impossible to compute a mean or in which the mean is not particularly representative of the distribution. Which of the following statements about the mean are true?
a. It is commonly referred to as the arithmetic average.
b. It is algebraically defined (that is, there is an equation you can use to calculate its value).
c. It is easily influenced by extreme scores.
d. It can be used for data that are measured on a nominal scale.
Answer: a. It is commonly referred to as the arithmetic average.
b. It is algebraically defined (that is, there is an equation you can use to calculate its value).
c. It is easily influenced by extreme scores.
Step-by-step explanation:
The mean is also referred to as the "average" and it is gotten by adding every number and the dividing the value gotten by the number of the numbers used for the calculation.
It should be noted that the mean is algebraically defined and can be easily influenced by extreme scores.

In 2017 the SAT had a mean score of 1060 with standard deviation of 195 (max score of 1600) while the ACT had a mean of 20.9 with standard deviation of 5.6 (max composite score of 36). Reed and Maria apply to the same college. Maria took the SAT and received a score of 1270 while Reed took the ACT and received a score of 27. Which student performed better in relationship to their peers
Answer:
Due to the higher z-score, Reed performed better in relationship to their peers
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
Whoever had the higher z-score performed better in relation to their peers.
Maria:
Took the SAT, grade 1270, so [tex]X = 1270[/tex]
Mean score of 1060 with standard deviation of 195 (max score of 1600). This means that [tex]\mu = 1060, \sigma = 295[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1270 - 1060}{295}[/tex]
[tex]Z = 0.71[/tex]
Reed:
Took the ACT, score of 27, so [tex]X = 27[/tex]
Mean of 20.9 with standard deviation of 5.6, which means that [tex]\mu = 20.9, \sigma = 5.6[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{27 - 20.9}{5.6}[/tex]
[tex]Z = 1.09[/tex]
Due to the higher z-score, Reed performed better in relationship to their peers
Solve for n. 35 = 9n - 10
Please don’t put a random answer for points.
Answer:
5
Step-by-step explanation:
First, you would add 10 to both sides to get 45 = 9n. Then, you would divide both sides by 9 to get n = 5. I hope this helps :)
Answer:
n = 5
Step-by-step explanation:
35 = 9n - 10
First, add 10 to each side.
35 + 10 = 9n - 10 + 10
45 = 9n
Divide both sides by 9
9n/9 = 45/9
n = 5

Answer:
81^84375
Step-by-step explanation:
Lily needed to get her computer fixed. She took it to the repair store. The technician
at the store worked on the computer for 4.5 hours and charged her $193 for parts.
The total was $530.50. What was the cost of labor, per hour?
The cost per hour for the labor will be $75
Total amount charged = $530.50
Amount charged for parts = $193
Number of hours used = 4.5 hours
Let the amount charged per hour = x
Therefore, the equation to solve the question will be:
193 + 4.5(x) = 530.50
193 + 4.5x = 530.30
Collect like terms
4.5x = 530.50 - 193
4.5x = 337.50
Divide both side by 4.5
4.5x/4.5 = 337.50/4.5
x = 75.
The cost of labor per hour is $75

The legs of the drafting table form vertical angles. Find the measures of ∠1, ∠2 and ∠3.
Answer:
m∡1 = 95°
m∡2 = 85°
m∡3 = 95°
Step-by-step explanation:
m∡1 + 85 = 180; m∡1 = 95°
m∡2 = 85° because it is vertical and congruent to the angle measured 85°
m∡3 = m∡1 = 95° because they are vertical and congruent
Answer:
1 = 95, 2 = 85, 3 = 95
Step-by-step explanation:
2 is an opposite angle of 85 degrees so 2 is 85 degrees
a line is always 180 degrees:
1 = 180 - 85 = 95 degrees
1 is an opposite angle of 3 so 3 is also 95 degrees

The sum of three consecutive numbers is 405. What is the
3rd numbers
Answer:
136
Step-by-step explanation:
Let the three consecutive numbers be a, a + 1, a + 2
Therefore,
a + a + 1 + a + 2 = 405
3a + 3 = 405
3a = 405 - 3
3a = 402
a = 402/3
a = 134
Third number = a + 2 = 134 + 2 = 136
