Answer:
c
Step-by-step explanation:
since the axis of symmetry is 0, and the y intercept is 2, the answer should be c
To get a full answer we would need the diagram but to solve it I would find the distances between her house and school and add that to the distance from her school to her work then from her work home if Thier isn't information for her distance from work to her home I would double the amount that she already went
Answer:
Number of leashes Bob can make in 2 hours = 7
Number of leashes Bob can make in 1 hour = 7÷2 = 3.5
Let, Bob takes total x hours.
Number of leashes Nina can make in 1 hour = 4
Let, Nina takes total x hours.
∴ The equation that can be used to find the number of hours it takes bob and Nina to make 60 leashes is given by-
3.5x+4x = 60.
7.5x = 60
This equation can be used to find the number of hours taken by Bob and Nina by putting different values of x and y which satisfies above equation.
Answer: 0.0129
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Sample size : 
Let X be the random variable that represents the age of of the fleets.
Z-score : 
For x = 14
By using standard normal distribution table , the probability that the average age of these 40 airplanes is at least 14 years old will be
Hence, the the probability that the average age of these 40 airplanes is at least 14 years old =0.0129
Answer:
29.15 km
Step-by-step explanation:
Given;
George walks; 25km west and then 15 km south
Resolving the directions to x and y axis;
North and South represent positive and negative y axis.
East and West represent positive and negative x axis respectively.
25km west
Rx = -25 km
15 km south
Ry = -15 km
The resultant displacement from the house is;
R = √(Rx^2 + Ry^2)
Substituting the values;
R = √((-15)^2 + (-25)^2)
R = √(225+625)
R = √(850)
R = 29.15 km
Therefore, he is 29.15 km from house
