Answer:

1/24

Step-by-step explanation:

Put 0.0416(For the 6, put in the recurring dot by doing shift and pressing x^2)

The calculator will then give you the fraction (if not click s arrow d).

The equivalent value of the fraction is A = 1/24

Given data ,

Let the fraction be represented as A

Now , the decimal number is given as

n = 0.041666666..

The decimal number is non-terminating , which indicates that the number si irrational

And ,

10000n = 416.666...

Simplify the fraction by dividing both sides of the equation by the greatest common divisor (GCD) of the numerator and denominator

On simplifying the equation , we get

A = 1 / 24

The simplified form of the fraction is A = 1/24

Hence , the fraction is A = 1/24

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.

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.

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

54 is one of the heights, so there would be a solid dot on 54. Because you need to be taller, the arrow would point to the right from the solid dot at 54 inches.

The correct graph is C ( the third one down)

The graph that represents the set of heights that satisfy this requirement is the third graph.

The requirment is that the heights of the people who ride the roller coaster should be at least 54 inches. This means that the height of the riders can be 54, 55, 100 0r 120.

Thus the graph that represents this is the graph that has a coloured circle on 54 and extends to number greater than 54.

Answer:

-2 2/5, -0.8, 0.5, 2/3

Step-by-step explanation:

We have four values, two that are fractions and two that are decimals and are asked to put them from least to greatest.

We have a dillema of values in this question, two are fractions and two are decimals. We need to convert all of them towards one symbol to get our answer.

Let's try decimals, since they are more easier to see which is the bigger value.

Start with 2/3, what is 2 divided by 3?

2/3

0.6 repeated.

As of now, we have 0.6 repeated, -2 2/5, 0.5, and -0.8.

Now do the second fraction, turn -2 2/5 to an improper fraction by multiplying the whole number by the denominator and adding the numerator.

-2 * 5 + 2

-10 + 2

-8/5

Now convert -8/5 to a decimal :

-8/5

-1.6

Now we have all decimals, put the from least to greatest.

0.6 repeated, -1.6, 0.5, -0.8

-1.6, -0.8, 0.5, 0.6 repeated

Therefore our list from least to greatest is :

-2 2/5, -0.8, 0.5, 2/3

(1) Many people fear spiders much more than they should. (2) Only a few spiders have a poisonous bite, and most spiders are not interested in biting humans anyway. (3) Even black widow spiders will not make you as sick as most people believe. (4) And tarantulas, though big and hairy, are gentle enough to be kept by young children as pets.

Many people fear spiders much more than they should. Therefore, sentence 1 in this paragraph states a 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.

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).
