Answer:
The probability that a randomly selected point within the circle falls in the white area is approximately 36.3%
Step-by-step explanation:
The given parameters of the area are;
The length of the radius of the circle, r = 4 cm
The length of the side of the inscribed quadrilateral, s = 4·√2 cm
The diagonals of the inscribed quadrilateral = 2 × The radius of the circle
∴ The diagonals of the inscribed quadrilateral are equal and given that the sides of the quadrilateral are equal, the quadrilateral is a square
The probability that a randomly selected point within the circle is white is given by the ratio of the white area to the brown square area as follows;
The white area = The total area - The area brown square
The total area, A = The area of the circle with radius, r = π·r²
∴ A = π·(4 cm)² = 16·π cm²
The area of the brown square, Asq = s² = 4·√2 cm × 4·√2 cm = 32 cm²
The white area, Aw = 16·π cm² - 32 cm² = 16·(π - 2) cm²
The probability that a randomly selected point within the circle falls in the white area is therefore;
[tex]P(W) = \dfrac{A_W}{T_A} = \dfrac{16 \cdot (\pi - 2) \, cm^2}{16 \cdot \pi \, cm^2 } \times 100= \left (1 - \dfrac{2}{\pi}\right) \times 100 \approx 36.338022763241865692 \%[/tex]
By rounding to the nearest tenth of a percent, we have;
The probability that a randomly selected point within the circle falls in the white area, P(W) ≈ 38.3%.

The following quadrilateral is a parallelogram. Solve for x, y, and z.
Answer:
x= 29°
y= 73°
z= 102°
Step-by-step explanation:
x is on the opposite side of the 29° which means it is equal to 29°
In order to find y we can add 29°+78° and subtract it from 180° since all triangles add up to 180°.
This makes y = 73°
In order to find z, we can subtract 78 from 180 since all straight lines are 180 degrees.
This makes z = 102°

Answer: i < 3u
Step-by-step explanation:
9x - 7i < 3 (3x -7u)
= 9x - 7i < 9x - 21u
= -7i < -21u (cancel out the 9x)

The following is a parallelogram. What is the measure of angle N?
Answer:120 Degrees
Step-by-step explanation:
Angle M and N add up to 180 degrees so,
180= 11x-40 (Since 3x+8x would be 11x)
220=11x (Add 40 to both sides)
X=20 (divided 220 by 11)

Hello there!
For each problem we are going to want to plug in the value of x (which is given) and find the total value of the expression
For #1
8(-4) + 4(-4)
8 * - 4 = -32
4*-4=-16
-32+(-16)=-48
So the answer to #1 is -48
For #2
9(3)-18
9*3=27
27-18=9
so the answer to #2 is 9
For #3
-2(8)+10
-2*8=-16
-16+10=-6
so the answer to #3 is -6
For #4
5(-3)+11
5*-3=-15
-15+11=-4
So the answer to #4 is -4

Michelle got an average score of 80 on two tests. What score must
she get on the third test so that her average score for the three tests
is the same as the average score for the first two tests?
Answer:
Michelle must get an 80 on her next test to keep her average score.
Step-by-step explanation:
Since Michelle got an average score of 80 on two tests, to determine what score she must get on the third test so that her average score for the three tests is the same as the average score for the first two tests, the following calculation must be performed:
X / 2 = 80
X = 80 x 2
X = 160
X x 3 = 80 x 3
X x 3 = 240
X = 240/3
x = 80
So, Michelle must get an 80 on her next test to keep her average score.

One equation in a system is y = 2x - 4. Which equation gives the system no solution?
y = 2x - 4
y = 2x + 9
y = 1/4x - 4
y = -2x + 4
Answer:
[tex]y = 2x + 9[/tex]
Step-by-step explanation:
Step 1: I have to compare the equation given to the equation of a straight line
From the question, we have:
[tex]y = 2x - 4 \\ y = mx + c[/tex]
hence m = 2 and c = -4
So, the choice B: y = 2x + 9
Gives : m = 2 and c = 9
Hence since m is the same that is (= 2) and c is different, hence the equation has not solution then.
So, the answer is choice B
Juan’s three math quizzes this week took him 1/3 hour, 4/6 hour, and 1/5 hour to complete. List the lengths of time in order from least to greatest.
Rewrite the fractions to have a common denominator:
1/3 = 10/30
4/6 = 20/30
1/5 = 6/30
Now compare the numerators and list from smallest to largest:
6/30, 10/30, 20/30
The order would be:
1/5, 1/3, 4/6
Answer:
1/5, 1/3, 4/6
Step-by-step explanation:
The bigger the fraction denominator the smaller is.
