Answer: Y=-5
Step-by-step explanation:
The reason is because if you look down the y axis from the origin you can see the location where the line crosses over the y axis in this case it was at (0,-5)
Answer:
H0 : μ = 0.75
H1 : μ > 0.75
Step-by-step explanation:
Given :
Sample size, n = 125
x = 99
Phat = x / n = 99 / 125 = 0.792
Population proportion, P = 0.75
The hypothesis :
Null hypothesis :
H0 : μ = 0.75
Alternative hypothesis ;
Egates the null hypothesis ; since the sample proportion is greater than the the population proportion or claim "; then we use the greater than sign.
H1 : μ > 0.75
Answer:
The plane travels at a speed of approximately 262.768 miles per hour.
Step-by-step explanation:
The absolute velocity of the plane () is the vectorial sum of vectors from engines () and wind flow (). All vectors are measured in miles per hour. That is:
(1)
Let suppose that both north and east semiaxes are positive.
If we know that and , then the resultant velocity of the plane is:
The resultant speed of the plane is determined by Pythagorean Theorem:
The plane travels at a speed of approximately 262.768 miles per hour.
