30x +9y =4
whats the value of x
Answer:
120 pine and 180 maple
Step-by-step explanation:
b. Event A is dependent on Event B.
c. Event B is dependent on Event A.
d. Events A and B are dependent on each other.
e. It is not possible to determine if the events are independent.
The true statement is that the (a) Event A is not dependent on Event B.
The equations are given as:
P(A | B) = 0.4
P(A) = 0.4
Two events A and B are independent if the following equations are true
P(A and B) = P(A) * P(B)
P(A | B) = P(A)
From the question, we have:
P(A | B) = P(A) = 0.4
This means that events A and B are not dependent
Hence, the true statement is (A)

b. the circumference of the Ferris wheel
c. the diameter of the Ferris wheel
d. the radius of the Ferris wheel
Answer: d. the radius of the Ferris wheel
Step-by-step explanation:
We now that the amplitude is the vertical distance between a peak or a valley and the equilibrium point.
Thus in the case of Ferris wheel the amplitude should be the difference between the peak(highest) and equilibrium point or equillibrium point and valley(lowest) points .
i.e. it should be half of the diameter of the circle. Since half of diameter of a circle is equals to radius.
Therefore, the amplitude of the function you use as a model should be equal to the radius of the Ferris wheel.
Based on the calculations, the depth of tent is equal to 12 feet.
Based on the diagram (see attachment) and information provided, we can logically deduce the following parameters (points):
Next, we would determine the height of the right-angled triangle (ADC) by applying Pythagorean theorem:
AC² = AD² + DC²
AD² = AC² - DC²
AD² = 5² - 3²
AD² = 25 - 9
AD² = 16
AD = √16
AD = 4 feet.
Also, we would determine the area of the triangle (ABC):
Area = 1/2 × b × h
Where:
Substituting the given parameters into the formula, we have;
Area = 1/2 × 6 × 4
Area = 12 feet².
Depth of tent = 3 × height of ADC
Depth of tent = 3 × 4
Depth of tent = 12 feet.
