The correct answer is B!!
maksim [4K]3 years ago
4 0

Answer:

B is the answer

Step-by-step explanation:

So common sense again

C and D are automatically out since they don’t equal

A and B are left

B’s slope is more accurate but it’s just not simplified, its still 2/3

so the slope is 2/3 and they are on the ame slope so we already know they equal so B is the correct answer.

Kruka [31]

Answer:

  10. Statement: Point P lies on line C'D'. Reason: The coordinates of P satisfy the equation of line C'D'.

Step-by-step explanation:

The equation for line C'D' in statement 8 appears to be in error. It should be ...

  y=\dfrac{-s}{2t-r}x+\dfrac{2st}{2t-r}

The coordinates of point P given in statement 9 are in error (they cannot be negative). They should be ...

  P = (2/3(r+t), 2/3s) . . . . . without the minus signs

This point will satisfy the equation of line C'D'. Here is the algebra. (Notice we have multiplied each term on the right of the above equation by (-1/-1).

  y=\dfrac{s}{r-2t}x-\dfrac{2st}{r-2t}\\\\\dfrac{2}{3}s=\dfrac{s}{r-2t}\cdot\dfrac{2}{3}(r+t)-\dfrac{2st}{r-2t}\qquad\text{substitute P for (x, y)}\\\\s(r-2t)=s(r+t)-3st\qquad\text{multiply by $\frac{3}{2}$(r-2t)}\\\\sr-2st=sr-2st\qquad\text{P satisfies the equation for line C'D'}

So, step 10 should say, in effect, P lies on C'D'.

<em>Comment on the proof</em>

IMO it is unfortunate that this proof has so many mistakes. Properly done, it is a nice demonstration that the medians are concurrent. It also demonstrates that the location of the centroid is 1/3 of the distance along the median toward the vertex.

I neeed helppp please due today
rjkz [21]

Step-by-step explanation:

y=x+6.......(1)

y=-3X-6....(2)

from eq (1), we get,

x=y-6....(3)

sub eq (3) in eq (2), we get

y= -3(y-6)-6

y= -3y+18-6

y+3y-12=0

4y=12

y=3

sub value of y in eq (3)

x=3-6

x=-3

Exhibit 5-9 Forty percent of all registered voters in a national election are female. A random sample of 5 voters is selected. R
Vikentia [17]

Answer:

Let X the random variable of interest "number of registered voters" in a random sample of n =5, on this case we now that:  

X \sim Binom(n=5, p=0.4)  

The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

Where (nCx) means combinatory and it's given by this formula:  

nCx=\frac{n!}{(n-x)! x!}  

So then the best answer for this cas would be:

b. the number of registered voters in the nation

Step-by-step explanation:

Previous concepts  

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".  

Solution to the problem

Let X the random variable of interest "number of registered voters" in a random sample of n =5, on this case we now that:  

X \sim Binom(n=5, p=0.4)  

The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

Where (nCx) means combinatory and it's given by this formula:  

nCx=\frac{n!}{(n-x)! x!}  

So then the best answer for this cas would be:

b. the number of registered voters in the nation
