pickupchik [31]

Answer:

D

Step-by-step explanation:

Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.

To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.

Keep in mind that these points are only roughly placed on the map.

But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.

To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.

47 - 35 = 12

To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.

122 - 78 = 44

I assume that the answer you should pick is D. (12, 44)

However, that doesn't exactly answer the question... it's worded a little weirdly.

To solve the rest of the equation, do the following:

Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.

a^2 + b^2 = c^2

12^2 + 44^2 = c^2

144 + 1936 = c^2

2080 = c^2

c = \sqrt{2080}

c = 45.61

The answer is 45.61 units.

Describe the difference between a probability derived from the analytic view (logical analysis), the Relative Frequency view (sa
oee [108]

Answer:

See the explanation

Step-by-step explanation:

<h2>Analytic View:</h2>

If and event can occur in A number of way and fail in B number of ways, then probability of its occurrence is:

P(A)= \frac{A}{A+B}

or probability of its failing is:

P(B)=\frac{B}{A+B}

<h3>Example:</h3>

Rolling a number smaller than 3 in a dice.

A= 2 (1,2)

B = 4 (3,4,5,6)

P(A)= \frac{2}{2+4}=\frac{1}{3}

<h2>Relative Frequency View:</h2>

Definition of Probability in terms of past performances (data). It can be taken as how often things happens divided by all outcomes.

<h3>Example:</h3>

A batter has 50 safe hits at 200 bats, which makes his batting average \frac{50}{200}= 0.25 which is the probability.

<h2>Subjective View:</h2>

When you define a probability due to personel beleif in the likelihood of an outcome. It involve no formal calculations and varies from person to person, depending on their past experience.

<h3>Example:</h3>

A person beleives that probability that the batter will hit safely in the next bat is 0.75

Where does the graph of y = –3x – 18 intersect the x-axis?
Naya [18.7K]

Answer:

b) (-6, 0)

Step-by-step explanation:

The quickest method to use is to put "0" in for <em>y</em><em>,</em><em> </em>then figure out which term for <em>x</em> would make the equation authentic, or genuine.

According to data from a General Motors study, the average speed of your trip A (in miles per hour) is related to the number of
polet [3.4K]

Answer:

(a)\hspace{3}-79.61mi/h^2

(b)\hspace{3}-4.36mi/h^2

Step-by-step explanation:

Let's rewrite the equation as:

A=26.5*(x^{-0.45 })

Now, let's find its derivate:

\frac{dA}{dx} =(-0.45)*(26.5)*x^{-0.45-1} =-11.925*x^{-1.45} =-\frac{11.925}{x^{1.45} }

Let's evaluate x=0.27 and x=2:

\frac{dA}{dx} \left \{  {x=0.27}} \right. =-\frac{11.925}{0.27^{1.45} }  =-79.61mi/h^2

\frac{dA}{dx} \left \{  {x=2}} \right. =-\frac{11.925}{2^{1.45} }  =-4.36mi/h^2

Keep in mind that when we derivate A(average speed) we find the average acceleration, thats why the result is given in mi/h^2, also it explains the minus sign, because for every stop you make on the trip you are decelerating.
