Answers
By applying the law of sine, the length of side BD is equal to 9.05 cm and the image of right-angled triangle BCD is shown in the image attached below.
How to calculate the length of BD?In order to determine the length of side BD, we would apply the law of sine because both side BD and side BC represent the opposite side and hypotenuse of right-angled triangle BCD respectively.
Mathematically, the law of sine is given by this mathematical expression:
sin(θ) = Opp/Hyp
Where:
Opp is the opposite side of a right-angled triangle.Hyp is the hypotenuse of a right-angled triangle.θ is the angle.Substituting the parameters into the formula, we have;
sin(θ) = BD/BC
sin(74) = BD/9.41
Cross-multiplying, we have:
BD = 9.41 × sin(74)
BD = 9.41 × 0.9613
BD = 9.05 cm.
By applying the law of sine, the length of side BD is equal to 9.05 cm and the image of right-angled triangle BCD is shown in the image attached below.

The perimeter of the square,
4x = P
Now P is = 32 units then,
32 units = 4(x)
x = 8 inches
So, the diameter of the cylinder formed by the rotation of 8 inches
Now, the circumference of the base is
C = 2πr = πD
If r =8 inches
C = π(8 units) = 8π units
C = 8(3.14) = 25.12 units

For a randomly chosen Monday, what is the probability there will be less than 340 column inches of classified advertisement?
Answers
For a randomly chosen Monday, the probability there will be less than 340 column inches of classified advertisement is 0.8413.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

In AUVW, m/U = (9x - 8)°, m/V = (2x + 2)°, and m/W = (3x + 4)º.
Find m/V.
Answers
Answer:
m∠V = 28°
Step-by-step explanation:
In ΔUVW:
m∠U = (9x - 8)°m∠V = (2x + 2)°m∠W = (3x + 4)°To find the measure of angle V, first find the value of x.
Interior angles of a triangle sum to 180°.
⇒ m∠U + m∠V + m∠W = 180°
⇒ (9x - 8) + (2x + 2) + (3x + 4) = 180
⇒ 9x + 2x + 3x - 8 + 2 + 4 = 180
⇒ 14x - 2 = 180
⇒ 14x = 182
⇒ x = 13
Substitute the found value of x into the expression for angle V:
⇒ m∠V = 2(13) + 2
⇒ m∠V = 26 + 2
⇒ m∠V = 28°
Therefore, the measure of angle V is 28°.
