prove that 8^6 +4^11 is divisible by 17. You're supposed to answer it likes this: [blank]*17
Answer:
262144*17 = 8^6 + 4^11.
Step-by-step explanation:
By using a calculator, we can see that 262144*17 = 8^6 + 4^11. Therefore, 8^6 + 4^11 is divisibly by 17.
Yes, the expression 8⁶ + 4¹¹ is divisible by 17.
And, You can use the fact that 8 is cube of 3 and 4 is square of 2.
The value in the blank space given is 2¹⁸.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
To prove 8⁶ + 4¹¹ is divisible by 17.
Now, We can convert 8⁶ + 4¹¹ in terms of 2 as;
⇒ 8⁶ + 4¹¹
⇒ (2³)⁶ + (2²)¹¹
⇒ 2¹⁸ + 2²²
⇒ 2¹⁸ (1 + 2⁴)
⇒ 2¹⁸ (1 + 16)
⇒ 2¹⁸ × 17
Thus, it is multiple of 17 and thus, divisible by 17.
Hence, The expression 8⁶ + 4¹¹ is divisible by 17.

Required:
a. Calculate the mean and the median ERAs for the New York Yankees.
b. Calculate the mean and the median ERAs for the Baltimore Orioles.
c. Based solely on your calculations above, which team is likely to have the better winning record?
1. New York Yankees
2. Baltimore Orioles
Answer:
(a): [tex]\bar x = 5.54[/tex] and [tex]Median = 4.86[/tex]
(b): [tex]\bar x = 5.27[/tex] and [tex]Median = 5.21[/tex]
(c): New York Yankees
Step-by-step explanation:
Given
Data of New York ERA and Baltimore ERA
Solving (a): Mean and Median of New York ERA
Mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
For New York ERA, n = 19. So, we have:
[tex]\bar x = \frac{3.13 + 2.88 + 4.99 + 3.99 + 4.68 + 5.80 + 6.81 + 0.98 + 4.86 + 5.93 + 2.88 + 3.92 + 4.08 + 3.00 + 7.50 + 9.00 + 5.40 + 7.36 + 18.00}{19}[/tex]
[tex]\bar x = \frac{105.19}{19}[/tex]
[tex]\bar x = 5.53631578947[/tex]
[tex]\bar x = 5.54[/tex]
To calculate the median value, we first arrange the data (in ascending order):
So, we have:
0.98, 2.88, 2.88, 3.00, 3.13, 3.92, 3.99, 4.08, 4.68, 4.86, 4.99, 5.40, 5.80, 5.93, 6.81, 7.50, 7.36, 9.00, 18.00
The median value of odd number of data is:
[tex]Median = \frac{1}{2}(n+1)\ th[/tex]
Substitute 19 for n
[tex]Median = \frac{1}{2}(19+1)\ th[/tex]
[tex]Median = \frac{1}{2}(20)\ th[/tex]
[tex]Median = 10th[/tex]
So, the median is the 10th item.
[tex]Median = 4.86[/tex]
(b): Mean and Median of Baltimore ERA
Mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
For Baltimore ERA, n = 17. So, we have:
[tex]\bar x = \frac{4.58+ 5.77+ 5.21+ 6.51+ 4.29+ 2.50+ 5.23+ 4.31+ 4.87+ 3.14+ 2.57+ 7.92+ 7.79+ 5.40+ 2.92+ 10.13+ 6.52}{17}[/tex]
[tex]\bar x = \frac{89.66}{17}[/tex]
[tex]\bar x = 5.27411764706[/tex]
[tex]\bar x = 5.27[/tex] --- approximated
Arrange in ascending order:
2.50 , 2.57 , 2.92 , 3.14 , 4.29 , 4.31 , 4.58 , 4.87 , 5.21, 5.23 , 5.40 ,5.77 , 6.51 , 6.52, 7.79 , 7.92 , 10.13
[tex]Median = \frac{1}{2}(n+1)\ th[/tex]
[tex]Median = \frac{1}{2}(17+1)th[/tex]
[tex]Median = \frac{1}{2}(18)th[/tex]
[tex]Median = 9th[/tex]
So, the median is the 9th item.
[tex]Median = 5.21[/tex]
(c): Who has a better record
Statistically, the average ERA of New York Yankees is better than the average ERA of Baltimore Orioles.
Hence, New York Yankees hold the better record

What is claim?Claims are the author's justifications for a position in writing. The thesis, or major contention, of an essay is often what the author intends the reader to learn from it. A thesis statement presents a logical argument for a topic. A writer will frequently give supporting evidence for lesser statements in addition to the primary argument.
There will always be a justification for a claim that a writer makes on a subject. Justifications to a point of view are provided by reasons. For instance, when a writer argues that weapons should be outlawed, they may do so out of safety concerns or because they have firsthand knowledge of gun violence. Many people fear spiders much more than they should. Sentence 1 in this paragraph states a claim.

Find the second derivative of the function.
Answer
The second derivative of an implicit function can be found using sequential differentiation of the initial equation F(x,y)=0. At the first step, we get the first derivative in the form y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y).

Answer:
B. 6 x 0.8
Step-by-step explanation:
It depends on the placement of the decimal point. All of the answers have 6 x 8. It's just that the decimal points are in different places each time.
For example, option A, is 6 x 8, which is 48. 48 is not equal to 4.8.
Option B, however, has 6 x 0.8. 6 x 8 = 48, and divided by 10 is 4.8. 4.8 = 4.8. This means Option B is correct.

9514 1404 393
Answer:
2. 3
Step-by-step explanation:
The "initial value" is the y-intercept. It is the value of y corresponding to an x-value of 0.
Your problem statement tells you that (0, 3) is one of the points on the line. That ordered pair tells you y=3 is the y-value that corresponds to x=0.
3 is the initial value
Suppose that 10 computer chips are randomly selected from a large shipment. If 95% of the computer chips work properly, and each chip works independently of one another, what is the probability that at least 8 of the chips work?
The probability that at least 8 out of the 10 chips work properly is 0.2614, or 26.14%.
Given:
number of chips selected = 10
probability of a chip working= 0.95
The probability of getting exactly k successes in n trials with a success probability p is given by the formula:
[tex]P(X = k) =[/tex] [tex]{\text} ^nC_k p^k (1 - p)^{(n - k)[/tex]
Now, the probability
P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10)
[tex]P(X = k) =[/tex] [tex]{\text} ^{10}C_k (0.95)^k (1 - 0.95)^{(10 - k)[/tex]
So, P(X = 8) = [tex]^{10}C_8 (0.95)^8(1-0.95)^{10-8}[/tex]
= [tex](45) (0.95)^8 (0.05)^2[/tex]
= 0.2753
and, P(X = 9) = [tex]^{10}C_9 (0.95)^9(1-0.95)^{10-9}[/tex]
= [tex](10) * (0.95)^9 * (0.05)^1[/tex]
= 0.3874
P(X = 10) = [tex]^{10}C_{10} (0.95)^{10}(1-0.95)^{10-10}[/tex]
= [tex](1) * (0.95)^{10} * (0.05)^0[/tex]
= 0.5987
Finally, sum up these probabilities to get the desired result:
P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10)
= 0.2753 + 0.3874 + 0.5987
= 0.2614
Therefore, the probability is 0.2614.
