Answer:

x = 35 , y = 72.5

Step-by-step explanation:

(a)

x and 35° are vertical angles and are congruent, then

x = 35

(b)

y. y and 35 lie on a straight line and sum to 180°, that is

y + y + 35 = 180

2y + 35 = 180 ( subtract 35 from both sides )

2y = 145 ( divide both sides by 2 )

y = 72.5

Answer:

y = 72.5 degrees

X = 35 degrees

Step-by-step explanation: A straight line is 180 degrees. The line with the two y degrees and the 35 degrees is a straight line, which is = 180 degrees. Because the y degrees are the same variable (y) they are equal degrees. All you need to do to find y is 180-35 =145. Divide that by 2 to find both y’s. 145 / 2 = 72.5. You can do the same for x, or realize that x and 35 are alternate interior angles, meaning they are the same measure: 35 degrees.

Answer:

mean=13.2

median=13

mode=14

Step-by-step explanation:

mean=sum of values/number of values

sum of values=9+17+14+12+14+14+9+11+10+20+10+22+11+11+9+15+14+15=237

number of values=18

mean=237/18=13.17

Mean=13.2

Arranging data in ascending order

9 9 9 10 10 11 11 11 12 14 14 14 14 15 15 17 20 22

n/2=18/2=9 is an integer so,

median= the average of (n/2)th and (n/2 +1)th observation

median=(12+14)/2=26/2=13

Median=13

Mode= The most repeated observation in the data

14 is repeated more than other numbers so, 14 is the mode for this data.

Mode=14

Answer:

Mark types the fastest rate of words per minute at 75 words per minute

Step-by-step explanation:

In this question, we want to know which of the three typists has the fastest typing rate.

To calculate this, what we need to do is to divide the total number of words they can type by the number of minutes taken to type those words.

For Natasha, we have; 2600 words / 40 minutes = 65 words per minute

For Henry, we have 4900 words/70 minutes = 70 words per minute

For Mark, we have 3750 words/50 minutes = 75 words per minute

We can see that Mark with 75 words per minute has the fastest typing rate

Find condition that zeros of polynomial p(x)=ax2+bx+c are reciprocal of each other

snow_lady [41]

Suppose $p(x)=ax^2+bx+c$ has two roots, reciprocals of one another. Call them $r_1,r_2$ , with $r_2=\dfrac1{r_1}$ .

Let's divide through $p(x)$ by $a$ for now. By the fundamental theorem of algebra, we can factorize $p(x)$ as

$x^2+\dfrac ba x+\dfrac ca=(x-r_1)(x-r_2)=(x-r_1)\left(x-\dfrac1{r_1}\right)$

Expand the RHS to get

$x^2-\left(r_1+\dfrac1{r_1}\right)x+1$

so we must have

$-\dfrac ba=r_1+\dfrac1{r_1}$
$\dfrac ca=1$

The first equation says $a$ and $b$ occur in a ratio of the negative sum of the roots of $p(x)$ , while the third equation says that the first and last coefficients $a,c$ must be the same.
