Which comparison is not correct? |-7| > -9 |-2| |-9| -8 < |-4|
Answer:
The third one is the one that's not correct.
Step-by-step explanation:
|8| is just 8 but |-9| is 9. So in that case |8| is not greater than 9.
Answer: it is the first one
Step-by-step explanation: the third one is not correct cause it is obviously less than 9

Step-by-step explanation:
Benford’s law states that the probability that a number in a set has a given leading digit, d, is
P(d) = log(d + 1) - log(d).
State which property you would use to rewrite the expression as a single logarithm, and rewrite the logarithm. What is the probability that the number 1 is the leading digit? Explain.
Answer:
Benford’s law states that the probability that a number in a set has a given leading digit, d, is
P(d) = log(d + 1) - log(d)
The division property of logarithm should be use to make it as a single logarithm
P(d) = log ( (d + 1)/ d)
So the probability that the number 1 is the leading digit is
P(1) = log ( ( 1+1)/ 1)
P(1) = log ( 2)
P(1) = 0.301
Step-by-step explanation:
Answer:
Use the quotient property to rewrite the expression. Write the difference of logs as the quotient log((d+1)/d). Substitute 1 for d to get log(2). Since log(2) = 0.30, the probability that the number 1 is the leading digit is about 30%.

The scores of the quizzes of five students in both English and Science are:
English Science
Student 1 6 8
Student 2 5 5
Student 3 9 6
Student 4 4 7
Student 5 8 9
For English, the mean is 6.4 and the standard deviation is 2.0. For Science, the mean is 7 and the standard deviation is 1.6. Using the formula below or Excel, find the correlation coefficient, r, for this set of scores. Answer choices are rounded to the nearest hundredth. ram-izlet 0
a) 0.23
b) 0.05
c) 0.50
d) 0.42
Answer:
0.23
Step-by-step explanation:
Given the data:
____(x) __(y)__(x - m1) /s1 ___(y-m2) /s2
1 ___6 ___8__ - 0.2 _______0.625
2 __5 ___ 5__ - 0.7________ - 1.25
3 __9____6__ 1.3 ________ - 0.625
4__ 4____ 7__ - 1.2 ______ 0
5__ 8 ____9 _ 0.8 _______ 1.25
For English :
Mean score(m1) = 6.4
Standard deviation (s1) = 2.0
For Science :
Mean score (m2) = 7.0
Standard deviation (s2) = 1.6
n = number of observations = 5
Correlation Coefficient (r) :
r = 1/(n - 1) Σ[((X - m1) / s1) * ((Y - m2) /s2)]
(-0. 2 * 0.625) + (-0.7 * - 1.25) + (1.3 * - 0.625) + (-1.2 * 0) + (0.8 * 1.25) = 0.9375
r = 0.9375/(5-1)
= 0.234
= 0.23

Shirley thought there were 25 students in her math class, but there were actually 27 students. What is her percent error?
27-25=2
so her absolute error was 2 students
divide the answer by 100 to get the percentage error.
percentage error = absolute error/ 100
2/100=0.02%
therefore her percentage error is 0.02%.
Find the range of the function
g(x) = 5 + / 4 - x
Answer:
The range of g(x) is [5, ∞) ⇒ (a)
Step-by-step explanation:
The range of the function is the values of y which corresponding to the values of x (domain)
∵ [tex]g(x)=5+\sqrt{4-x}[/tex]
∵ There is no square root for negative values
∴ 4 - x ≥ 0
→ Add x to both sides
∴ 4 - x + x ≥ 0 + x
∴ 4 ≥ x
→ that means x is smaller than or equal to 4
∴ x ≤ 4
→ The greatest value of x = 4
∴ The domain of g(x) = {x : x ≤ 4} ⇒ (-∞, 4]
→ At x = 4
∵ g(4) = 5 + [tex]\sqrt{4-4}[/tex]
∴ g(4) = 5 + 0
∴ g(4) = 5
→ That means the smallest value of y = 5 because [tex]\sqrt{4-x}[/tex] is always
give a positive value which add to 5
∴ The range of g(x) is {y : y ≥ 5} ⇒ [5, ∞)
The right answer is (a)

6. The drawing below shows a ladder leaning against a building. Part A:
How tall is the building? Round your answer to the nearest tenth. Show or
explain your answer using words, numbers, and/or symbols in your
explanation.
YOZ
10 ft
Your answer
Answer:
Height = 17.3 ft
Step-by-step explanation:
The diagram depicts a right angled triangle and will be solved using Pythagoras theorem.
Represent the length of the ladder with L
L = 20
Represent the distance between the ladder and thr building with B
B = 10
Represent the height with of the building with H
Solving for H, we have
H² + B² = L²
H² + 10² = 20²
H² + 100 = 400
H² = 400 - 100
H² = 300
H = √300
H = 17.320508075688772
H = 17.3 (approximated)
Hence, the height of the building is 17.3 ft

How do you solve this problem
(2x+8)2=64
Answer:
12
Step-by-step explanation:
If (2x+8)2 = 64, then I would solve it by making sure the numbers in the parentheses equal 32. This is because it would get multiplied by 2 after you find the answer and 32 x 2 is 64. So what times 2 is 24? 12. 12 x 2 is 24, plus 8 is 32, and multiply 32 by 2 and you get 64 :) I'm not the best at explaining btw ;-;

There are supposed to be biscuits in a frozen package, but there could be as many extra or fewer in each bag, depending on the weight of the biscuits.
Solving the equality will give the highest and lowest amounts of biscuits in the bag.
Answer:
See Explanation
Step-by-step explanation:
The question has missing details.
However, I'll make the following assumptions:
[tex]Biscuits = 20[/tex]
[tex]Difference = 2[/tex] (Fewer/Extra)
To solve your question, simply change the numbers
Required
Determine the range of the biscuits
To calculate the number of minimum biscuits, we have:
[tex]Minimum = Biscuits - Difference[/tex]
[tex]Minimum = 20 - 2[/tex]
[tex]Minimum = 18[/tex]
To calculate the number of maximum biscuits, we have:
[tex]Maximum = Biscuits + Difference[/tex]
[tex]Maximum = 20 + 2[/tex]
[tex]Maximum = 22[/tex]

What is the side length of a rectangular prism with a volume of 8 ft3?
Answer:
The side length of the rectangular prism is 2 feet
Step-by-step explanation:
The volume of the rectangle prism = L × W × H, where
L is its lengthW is its widthH is its heightIf the 3 dimensions of the rectangular prism are equal, then its
volume = L × L × L = L³
In the question
∵ The rectangular prism has a volume = 8 ft³
∵ The question asks for its side length
→ That means all dimensions are equal
∴ V = L³
→ Substitute V by 8
∴ 8 = L³
→ Take cube root for both sides
∴ ∛8 = ∛(L³)
∴ 2 = L
∴ L = 2 ft
The side length of the rectangular prism is 2 feet

What is the probability that the true proportion of time spent mowing is exactly equal to the sample proportion
This question is incomplete, the complete question is;
The manager of Lawn and Garden Services would like to estimate the proportion of her employees' time spent performing various gardening and lawn care activities. She has made 400 random observations of a typical worker, with the following results:
Activity Time Observed
Mowing 200
Trimming 80
Raking 40
Miscellaneous 80
What is the probability that the true proportion of time spent mowing is exactly equal to the sample proportio;
Multiple Choice
a) 1
b) 0
c) 5
d) 2
e) 1
Answer:
b) 0
Step-by-step explanation:
Given that;
Activity Time Observed
Mowing 200
Trimming 80
Ranking 40
Miscellaneous 80
Total 400
Now since proportion of time spent on mowing will be
200 / 400 = 0.5
there will be no chance that the true proportion of time spent mowing is exactly equal to the sample proportion.
Where true proportion is 200 and sample is 400
So the probability is 0.

(Round to one decimal place as needed.) d) What percent of all students were accepted? The percent of all students who were accepted is nothing%. (Round to one decimal place as needed.)
Answer:
Follows are the solution to this question:
Step-by-step explanation:
The missing data is defined in the attached file please find it.
Given:
Admission Status
[tex]\left\begin{array}{ccccc}Ethnography &Acceptable \ Approval &Waitlisted & Turned \ Away & Total\\\\ Hispanic/ Black & 51 &206&143 & 400 \\Asia &57&289&100&446\\White& 62&222&145&429\\ Total & 170& 717& 388& 1275\end{array}\right \\\\\\[/tex]
In point A:
The overall percent of applicants, which is Asia:
[tex]= \frac{446}{1275} \\\\ = 0.3498039 \approx 34.98 \%[/tex]
In point B:
The overall percent of the students, who admitted to Asia:
[tex]P(accepted\ Asian) = P( \frac{Placcepted \ Asian}{Asian})[/tex]
[tex]= \frac{\frac{57}{1275}}{\frac{446}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{446} \\\\= \frac{57}{446} \\\\= 0.1278027\approx 12.78 \%[/tex]
In point C:
The Asian percentage approved:
[tex]P(Asian/accepted) =\frac{P(accepted, Asian)}{P(accepted)}\\[/tex]
[tex]=\frac{\frac{57}{1275}}{\frac{170}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{170} \\\\= \frac{57}{170} \\\\= 0.3352941\approx 33.52%[/tex]
In point D:
The number of all students admitted:
[tex]=\frac{170}{1275}\\\\= 0.13333 \\\\= 13.33%[/tex]
