The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides. That is, for any triangle ABC, the bisector of the angle at C divides the opposite side into segments of length x and y such that a/b = x/y.

8 = 3y - 12 - 8y What is the value of y?
Elan Coil [88]

Answer:

y = -4

Step-by-step explanation:

8 = 3y - 12 - 8y

Combine like terms

8 = -5y -12

Add 12 to each side

8+12 - 5y-12+12

20 = -5y

Divide each side by -5

20/-5 = -5y/-5

-4 =y

A researcher conducted an Internet survey of 500 students at a particular college to estimate the average amount of money studen
bonufazy [111]

Answer:

The margin of error is  ME = 2.2962

Step-by-step explanation:

From the question we are told that

     The number of student is n = 500

     The highest amount is  A =$200

     The lowest amount is  B = $75

       The sample mean is  x = &140

The Standard deviation  of this set is mathematically evaluated as

            s =  \frac{A-B}{4}

Substituting values

            s =  \frac{200-75}{4}

            s = 31.25

The margin of error (ME) is mathematically evaluated as

            ME =  t_{n-1}__{\alpha }} *  \frac{s}{\sqrt{n} }

Where  t_{n-1}__{\alpha }} is the critical value for \alpha  = 0.05 i.e the significance level

     From the critical value table this is  t_{n-1}__{\alpha }}  =  1.649

So

       ME =  1.649  *  \frac{31.25}{\sqrt{500} }

      ME = 2.2962

If x is a prime number, what is the value of x? (1) 2 x + 2 is the cube of a positive integer. (2) The average of any x consecut
Triss [41]

Answer: what is the value of x? The answer is 3.

Step-by-step explanation:

2x + 2 = y^3 where y is a positive integer. One possible answer for this is 3, because 2*3 + 2 is 8, that is 2^3, so 2 * 2 * 2 = 8. Also the second restrictions says that x consecutive numbers added and then divided by x will give an integer. So 2 + 3 + 4 = 9 and 9/3 = 3, that is an integer, and we have 3 consecutive numbers, therefore the answer is 3, as 3 is prime as well.

Sal is making bracelets for a fundraiser.he uses 6 inches of yarn per bracelets how many bracelets can sal make with 5 feet of y
kodGreya [7K]

Answer:-Sal can make 10 bracelets with 5 feet of yarn.


Explanation:-

We know that 1 foot = 12 inches

⇒1 inch=\frac{1}{12}\ foot

Yarn used for 1 bracelet = 6 inches=\frac{6}{12}\ feet=0.5 foot

Number of bracelets made in 5 feet=\frac{5}{0.5}=10

therefore, Sal can make 10 bracelets with 5 feet of yarn.
