Answer:

x = 15.

Step-by-step explanation:

We apply the tangent-secant theorem:

18^2 = 12(12+x)

324 = 144 + 12x

12x =  324 - 144 = 180

x = 180/12 = 15.

The value of angle x is 127 degrees.

<h3>How to find angles?</h3>

The angle x can be found as follows:

Angle on a straight line is 180 degrees.

Therefore, the sum of 53 degrees and x degrees is 180 degrees.

Therefore,

53 + x = 180°(sum of angles on a straight line)

subtract 53 from both sides of the equation

53 - 53 + x = 180 - 53

x = 127°

Therefore, the angle of x is 127 degrees.

Well 17-3 gets you 14 which would be half of her apples. 14x2=28 therefore, Daphne originally had 28 apples. She gave away 17 which means she kept 11 for herself

4, 6, 2, 8, 4, 4, 2, 10<br> Mean:<br> Median:<br> Mode:
Troyanec [42]

Answer:

Mean: 5

Median: 4

Mode: 4

Step-by-step explanation:

Mean:

1. To find the mean given a data set, you have to add up all the data points and then divide them by the number of data points there is.

  • \frac{4+6+2+8+4+4+2+10}{8}
  • \frac{40}{8}
  • 5

Therefore, the mean is 5.

Median:

1. To find the median given a data set, we first have to arrange the data points in order.

  • 2, 2, 4, 4, 4, 6, 8, 10

2. Next, we have to find which data point is in the middle. In this case, the middle number is 4.

Therefore, the median is 4.

Mode:

1. To find the mode given a data set, you just have to find which data point is the most frequent.

  • 1 data point of  2
  • 3 data points of 4
  • 1 data point of 6
  • 1 data point of 8
  • 1 data point of 10

Because the most frequent value is 4, the mode is 4.
