Answer:

Step-by-step explanation:

Lengths:

WX: 2

XY: 2

WY: sqrt[(4-2)² + (2-4)²]

sqrt(4+4)

4sqrt(2)

W'(8, 16), X'(8, 8), Y'(16, 8)

W'X': 8 --> 4 × 2

X'Y': 8 --> 4 × 2

W'Y': sqrt[(16-8)² + (8-16)²]

sqrt(64 + 64)

8sqrt(2) --> 4 × 2sqrt(2)

At the Canada Open Tennis Championship, a statistician keeps track of every serve that a player hits during the tournament. The

kondaur [170]

Answer:

a) 54 mph to 144 mph

Step-by-step explanation:

We don't know the shape of the distribution, so we use Chebyshev's Theorem to solve this question. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

At least eight-ninths of the player's serves.

8/9 is approximately 89%

Mean: 99, standard deviation: 15

99 - 3*15 = 54

99 + 3*15 = 144

So the correct answer is:

a) 54 mph to 144 mph

In the figure above line m is parallel to line n.

enot [183]

Given:

Line m is parallel to line n.

The measure of ∠1 is (4x + 15)°

The measure of ∠2 is (9x + 35)°

We need to determine the measure of ∠1

Value of x:

From the figure, it is obvious that ∠1 and ∠2 are linear pairs.

Thus, we have;

$\angle 1+\angle 2=180^{\circ}$

Substituting the measures of ∠1 and ∠2, we get;

$4x+15+9x+35=180$

$13x+50=180$

$13x=130$

$x=10$

Thus, the value of x is 10.

Measure of ∠1:

The measure of ∠1 can be determined by substituting x = 10 in the measure of ∠1

Thus, we have;

$\angle 1 =4(10)+15$

$=40+15$

$\angle 1=55^{\circ}$

Thus, the measure of ∠1 is 55°
