Answer:
P(X < 7) = 0.76
Step-by-step explanation:
Counting properly from the diagram attached to the question,
number of trials it took her to make less than 7 shots(i.e. 0 to 6 shots) = 38
The total number of trials she made = 50
Probability that it takes fewer than 7 shots to get her first successful shot, P(X < 7) = (number of trials it took to make less than 7 shots)/(Total number of trials)
P(X < 7) = 38/50
P(X < 7) = 0.76
Answer:
18
Step-by-step explanation:
1) 90 --- 100%
x --- 20%
x = 90*20/100 = 18
2)
20 % = 20/100 = 0.2
20 percent (0.2) of (*) 90 = 0.2*90 = 18
Well to find out what n is, let's look at the whole numbers around the value of 6.7, so it would be 6 and 7.
From the list, square root of which larger number will provide you with 6 and 7.
It would be C. Since the square root of 36 is 6 and square root of 49 is 7. Knowing this the square root of n, some unknown number must then be between the numbers of 36 and 49, as the square roots of those numbers respectively are 6 and 7. Square root of n which is 6.7 is found between them.
The kite forms a right angled triangle with hypotenuse of 50 ft. The height of the kite above the ground is the opposite of 60° angle.
Using the sine rule,
Sin 60 = Height of the kite above the ground/Hypotenuse
Therefore,
Height of the kite above the ground = Hypotenuse*Sin 60 = 50 *Sin 60 = 43.3 ft
Answer:
The components form of the vector is:
V = [-3,3]
Step-by-step explanation:
The initial point is V(i) = (-1,2) and the final point V(f) = (-4,5). If we want to get the components form, we just need to subtract each component of the points.
a = -4-(-1) = -4+1 = -3
b = 5-2 = 5-2 = 3
a represents the x-componet and b the y-component of the vector.
Therefore, the components form of the vector is:
V = [a,b]
V = [-3,3]
