Brian compared the decimals 66.10, 21.10, and 66.11.

Please can anyone help answer this question? It would be greatly appreciated!!! :)

Ray Of Light [21]

Answer:

0.667

Step-by-step explanation:

Angle in a circle = 360°

Area of total shaded parts = 60 + 60 = 120°

Area of total unshaded parts = 360-120 = 240°

Probability that a random selected point within the circle falls in the unshaded area

= 240/360

= 2/3

≈ 0.667

I apologize in advance if I made a mistake.

liraira [26]

Answer:

50 questions.

Step-by-step explanation:

70% - 35

100% - $\frac{100}{70}$ × 35 = 50

Which statement must be true? Two triangles placed side by side. Two sides each of the triangles are equal in length. The third

sladkih [1.3K]

It is impossible to determine the relationship between x and y from the question about the triangle. Hence, the correct option is D. This is because none of the sides are labelled x or y from the information provided.

<h3>What are the relationships that exist between the sides of a triangle?</h3>

It is important to note that:

The side with the highest length is the side that is opposite the biggest angle.

It is also important to note that the angle that is least will always be opposite the side that is smallest.

A system of linear inequalities is shown below:

Yuki888 [10]

The 4th selection is appropriate:
The first line is a dashed line which joins ordered pairs (-2, 1) and (3, 1). The second line is a dashed line and joins ordered pairs (-2, -2) and (3, 3). The portion common above the first line and above the second line is shaded

The fracture toughness (in ) of a particular steel alloy is known to be normally distributed with a mean of 28.3 and a standard

Effectus [21]

This is a conditional probability question.

The conditional probability is given as follows: The probability of an event A given B is given by

$P(A|B)= \frac{P(A\cap B)}{P(B)}$

Thus, given that the fracture toughness of a particular steel alloy is known to be normally distributed with a mean of 28.3 and a standard deviation of 0.77.

The probability that the fracture toughness will be between 29 and 40.3 given that the <span>fracture toughness is at least 27 is given by

$P(29 \leq X \leq 40.3 \, | \, X \geq 27)= \frac{P(29 \leq X \leq 40.3)\cap P(X \geq 27)}{P(X \geq 27)} \\ \\ =\frac{P(29 \leq X \leq 40.3)}{P(X \geq 27)}$

$P(29 \leq X \leq 40.3)=P\left(z \ \textless \ \frac{40.3-28.3}{0.77}\right)- P\left(z \ \textless \ \frac{29-28.3}{0.77}\right) \\ \\ =P(z\ \textless \ 15.58)-P(z\ \textless \ 0.91)=1-0.81835=0.18165$

$P(X \geq 27)=1-P(x\ \textless \ 27) \\ \\ =1-P\left(z\ \textless \ \frac{27-28.3}{0.77}\right)=1-P(z\ \textless \ -1.688) \\ \\ =1-0.04568=0.95432$

Thus, </span>the probability that the fracture toughness will be between 29 and 40.3 given that the <span>fracture toughness is at least 27 is given by</span>

$\frac{P(29 \leq X \leq 40.3)}{P(X \geq 27)}= \frac{0.18165}{0.95432} =\bold{0.1903}$
