Answer:
B
Step-by-step explanation:
Use the pythagorean theorem
a² + b² = c²
a² + 63² = 65²
a² + 3969 = 4225
a² = 256
a = 16
x = 16 meters
(X-4, y-9) since it moves left its negative and the y went down makes that negative too
1.12=1 12/100=1 3/25
or 28/25
Answer:
z-value of rachel = 1.875
z-value of rob = -2
z-value of Rachel is more than that of rob. Thus rob is earning below average and rachel is earning above average.
Step-by-step explanation:
Let's denote the salary of Rob and Rachel per year by X. So, X = $50,000
We are told that;
For Rachel's industry;
Mean salary;μ1 = $35,000
Standard deviation;σ1 = $8,000
For Rob's industry;
Mean salary;μ2 = $60,000
Standard deviation;σ2 = $5,000
Formula for z - value is;
z = (X - μ)/σ
Thus;
z-value for rob is;
z2 = (X - μ2)/σ2
z2 = (50000 - 60000)/5000
z2 = -2
z-value for rachel is;
z1 = (X - μ1)/σ1
z1 = (50000 - 35000)/8000
z1 = 1.875
z-value of Rachel is more than that of rob. Thus rob is earning below average and rachel is earning above average.
Answer: infinitely many
Step-by-step explanation:
In geometry , A line is a straight (one dimensional ) undefined figure which has no thickness. It extends infinitely in each direction (no-endpoint).
A point is also a undefined geometric figure that has no dimension , it helps to get the exact location of any figure on plane.
Since a line extends infinitely in both directions, so there are infinite number of points contained by it.
Thus , the number of points are contained on a line = Infinitely many
