7 • 5
Multiplication is basically repeated addition. So to convert repeated addition to multiplication, we take the number being added (7) and multiply it be the number of addens (5). Therefore, 7+7+7+7+7 = 5 • 7
Answer:
i think you have to multiply the sides..

Answer:
A. The probability of event A
Step-by-step explanation:
The proportion of times a particular event A occurs is known as the probability of event A because the probability is the measure of uncertainty and by definition probability is calculated as
P(x)=X/n
where
P(x) is the probability of occurring of random variable X
X=number of favorable outcomes
and
n= total number of outcomes.
Thus, the proportion of times a particular event A occurs is known as the probability of event A.
Answer:
7,042
Step-by-step explanation:
Answer:
Question 1: The hours that will pass between two consecutive times, when the water is at its maximum height is π hours
Question 2: Sin of the angle is -0.8
Step-by-step explanation:
Question 1: Here we have h(t) = 4·cos(t) + 10
The maximum water level can be found by differentiating h(t) and equating the result to zero as follows;


∴ sin(t) = 0
t = 0, π, 2π
Therefore, the hours that will pass between two consecutive times, when the water is at its maximum height = π hours.
Question 2:
B = (3, -4)
Equation of circle = x² + y² = 25
Here we have
Distance moved along x coordinate = 3
Distance moved along y coordinate = -4
Therefore, we have;

Sinθ = sin(-53.13) = -0.799≈ -0.8.
