Answer:

y is 107° and z is 36°

Step-by-step explanation:

73° and y are supplementary angles so they add up to 180°

Answer:

y = 107

z = 36

Step-by-step explanation:

We are given that line o is parallel to line m, and we can notice line k is a transversal through them both. Using same side interior angles, we can say that:

y + 73 = 180

and

y = 107

Next, using vertical angles, we can say that:

5z - 73 = y

We already have y = 107, so we can substitute that in:

5z - 73 = 107

5z = 180

z = 36

Answer:

[tex]\theta=71.07^{\circ}[/tex]

Step-by-step explanation:

The given vector is :

v = -12i - 35j

We need to find the angle direction of v.

The general vector is given by :

v = xi+yj

The direction angle is :

[tex]\theta=\tan^{-1}(\dfrac{y}{x})[/tex]

We have, x = -12 and y = -35

So,

[tex]\theta=\tan^{-1}(\dfrac{-35}{-12})\\\\\theta=71.07^{\circ}[/tex]

So, the required direction angle is [tex]71.07^{\circ}[/tex].

Answer:

9. x = 5

10. AD = 7

Step-by-step explanation:

As shown in the diagram, BD is a perpendicular bisector. And D is a point on the perpendicular bisector, meaning it is equidistant from the endpoints on the segment(points A and C). Because of this, we can say AD = CD.

We can substitute to get:

2x - 3 = x + 2

And simplify and solve:

x - 3 = 2

x = 5

AD is just 2x - 3, so we can substitute in x to find AD:

AD = 2(5) -3

AD = 10 - 3

AD = 7

Answer:

The probability that the person uses exactly one of the facilities is 69.23%.

Step-by-step explanation:

Since there are 130 people in a sport center, of which 65 people use the gym, 51 people use the swimming pool, 44 people use the track, 15 people use the gym and the pool, 14 people use the pool and the track. , 10 people use the gym and the track and 1 person uses all three facilities, to determine, if a person is selected at random, what is the probability that the person uses exactly one of the facilities, the following calculation must be performed:

130 = 100

130 - 1 - 15 - 14 - 10 = X

130 = 100

90 = X

90 x 100/130 = X

9,000 / 130 = X

69.23 = X

Therefore, if a person is selected at random, the probability that the person uses exactly one of the facilities is 69.23%.

10  5/6  =   65/6

2  1/4    =  9/4

2 (9/4)  =   9/2

So   the  length  left   is

65/6  -  9/2    =

65/6  -  27/6   =

Example: -2+5=3

-17-5=-22

The mean absolute deviation of the number of points scored is 4.4.

The mean deviation is used to calculate how far the values fall from the mean of the data set.

Here, Given data is 31, 20, 27, 19, 28

Mean = Sum of all data / number of terms

         = (31 + 20 + 27 + 19 + 28)/5

         = 125/5

         = 25

Then, the deviation will be 6, 5, 2, 6, 3

Mean Deviation = Sum of Deviation / Total number of deviation

                          = ( 6 + 5 + 2 + 6 + 3) / 5

                          = 22 / 5

                          = 4.4

Thus, the mean absolute deviation of the number of points scored is 4.4.

Answer:

Step-by-step explanation:

(1)  6 yd 1 ft plus 9 yd 1 ft works out to 15 yd 2 ft, or 15 2/3 yd.

(2)    8' 3" less 5' 5" requires "borrowing."  Since 1 ft = 12 in, your 8' 3" becomes 7' 12".

 Subtracting 5' 5" from 7' 12" yields 2' 7"

(3)    25 lb 8 oz less 15 lb 10 oz also requires borrowing.

        1 lb = 16 oz, so:

       25 lb 8 oz = 24 lb 24 oz.  Then we subtract 15 lb 10 oz from 24 lb 24 oz:

        9 lb 14 oz

Answer:

using Pythagoras theorem x=32.7

Answer:

21.7

Step-by-step explanation:

In order to solve this problem, we can use trig functions. We are given the side adjacent to the 37° given and we are looking for the hypotenuse. This means that cosine function is the most suitable. Cosine is written as:

cos(θ°) = adjacent / hypotenuse

We can substitute the values we have:

cos(37°) = 17.3 / x

And rewrite the expression:

x = 17.3 / cos(37°)

Then, use a calculator to evaluate:

x = 21.66194689

This can be rounded to 21.7
