Given: AB tangent at D, AD = OD = 4 Find: Area of the shaded region

Mathematics
1 answer:
MrMuchimi3 years ago
4 0

Answer:

1.72

Step-by-step explanation:

AB tangent at D, AD = OD = 4

so triangle OAD is right angle with side of 4 and 4.

area of OAD = 1/2 * 4 * 4 = 8

Angle AOD = DAO = 45 deg.

so circular sector OCD area = area of circle O * 45/360

= pi * 4 * 4 * 45/360

= 2pi

Shade area ACD = trigangle OAD - circular sector OCD

= 8 - 2pi

= 1.72

Clarke, one of the students, constructed a 95 percent confidence interval for p as 0.215±0.057 . Does the interval provide convi
madam [21]

Step-by-step explanation:

With a fair die, the probability of rolling a 6 is 1/6 or 0.167.

For the baked die, the low end of the confidence interval is 0.215 − 0.057 = 0.158.

Since 0.167 is within the range of the confidence interval, there is not convincing statistical evidence that a baked die will have a higher probability of rolling a 6 than a fair die.

Terry, Kevin and barry together have 215 marbles. Terry has 20 marbles more than Barry and kevin has 10 marbles more than Terry.
Zarrin [17]
Terry, Kevin and Barry have a total of 215 marbles.=> Terry has 20 marbles more than Barry = x + 20=> Kevin has 10 marbles more than Terry = (x + 20) + 10=> Barry = xSolutions:=> x + x + 20 + x + 20 + 10 = 215=> 3x + 50 = 215=> 3x = 215 - 50=> 3x = 165=> 3x / 3 = 165 / 3=> x = 55Barry have = 55Terry = 55 + 20 = 75<span>Kevin => 75 + 10 = 85</span>

Find the value of x and y
bagirrra123 [75]
According to google, the red marks mean those two lines are the same length.  If that's the case, we know that x is the angle in both corners of the lower triangle.  We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40.  That leaves 140 for the rest.  Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees.  It is divided in two parts, the lower one of which we just found to be 20.  So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees

Sydney wrote the equation y+1=12(x−3). y + 1 = 1 2 ( x − 3 ) . Explain her error and then write the correct equation in point-sl
yanalaym [24]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Given equation:

\to y + 1 = 12 ( x - 3 )

Using formula:

\to \bold{y = mx +c}

Solving the given equation:

\to y + 1 = 12 ( x - 3 )\\\\\to y+1 =12x-36\\\\\to y=12x-36-1\\\\\to y= 12x-37\\\\

compare the value form the given formula:

\to m= 12

Correct equation \to  y= 12x-37

solpe \to m= 12
