Answer:

x=15

Converse: If line x and y are parallel then angles on the same line are supplementary angles.

Step-by-step explanation:

<em><u>Converse:</u></em>

Let's start with the converse, so if line x and y are parallel then angles on the same line are supplementary angles. I'm not sure if that's the converse your teacher wants but my teacher taught me this.

<em><u>Finding x:</u></em>

Now we know that the angles are supplementary angles, that means if w add them together we get 180°. So our equation will be 10x-22+3x+7=180. Now we just solve it. We start by combining like terms, then adding the 15 to both sides, and lastly we divide the 13 to both sides and get...

10x-22+3x+7=180\\13x-15=180\\13x=195\\x=15

x=15

For a recent​ year, the following are the numbers of homicides that occurred each month in New York​ City: 38,​ 30, 46,​ 40, 46,
lubasha [3.4K]

Answer:

Each month is equally likely

Step-by-step explanation:

Given that for a recent​ year, the following are the numbers of homicides that occurred each month in New York​ City:

38,​ 30, 46,​ 40, 46,​ 49, 47,​ 50, 50,​ 42, 37, 37.

We have to check whether it is equally likely for each of the 12 months

Set Hypotheses as

H0: All months are equally likely

Ha: atleast two months are not equally likely

(Two tailed chisquare test at 5% significance level)

This is a test for chi square goodness of fit and so assuming H0 to be true

we divide the total equaly among 12 months as expected

              Observed Expected  Chi square

Jan                    38     42.66666667  0.510416667

Feb                    30     42.66666667  3.760416667

Mar                    46     42.66666667  0.260416667

Apr                   40    42.66666667  0.166666667

May                   46    42.66666667  0.260416667

June           49    42.66666667  0.940104167

July                   47    42.66666667  0.440104167

Aug                  50    42.66666667  1.260416667

Sep                  50    42.66666667  1.260416667

Oct                  42    42.66666667  0.010416667

Nov                  37    42.66666667  0.752604167

Dec                  37    42.66666667  0.752604167

Total        512     512                 10.375

df=11

p value = 0.497

Since p >0.05 our alpha we accept H0

Each month is equally likely

Describe the vector as an ordered pair around coordinates to the nearest 10th the diagram is not drawn to scale
xxMikexx [17]

Answer:

see explanation

Step-by-step explanation:

x = r cosΘ

y = r sinΘ

with r = 54 and Θ = 69°, thus

x = 54cos69° ≈ 19.4

y = 54sin69° ≈ 50.4

Thus (54, 69° ) as an ordered pair

= \left[\begin{array}{ccc}19.4\\50.4\\\end{array}\right]

Winning the jackpot in a particular lottery requires that you select the correct four numbers between 1 and 42 ​and, in a separa
NARA [144]

Answer:

\dfrac{1}{3,357,900}

Step-by-step explanation:

There are

C^{42}_4=\dfrac{42!}{4!(42-4)!}=\dfrac{42!}{4!\cdot 38!}=\dfrac{38!\cdot 39\cdot 40\cdot 41\cdot 42}{2\cdot 3\cdot 4\cdot 38!}=39\cdot 10\cdot 41\cdot 7=111,930

different ways to select the  four numbers between 1 and 42. Only one of this ways is correct (successful to win).

There are 30 different ways select the single number between 1 and 30. Only one of them is correct.

The  probability of winning the jackpot is

\dfrac{1}{111,930}\cdot \dfrac{1}{30}=\dfrac{1}{3,357,900}
