Step-by-step explanation:
Mia walked 7km/h so after 1 hour, she is 7 km north of the house of Julia
Samantha walked 11km/h so after 1 hour, she is 11 km west of the house of Julia.
The points where Mia and Samantha are after 1 hour , and the house of Julia form a right triangle with sides 7 and 11 km. The distance between the girls, is the hypotenuse of his triangle.
by the pythagorean theorem:
Answer: 13 km
Answer:
Mean = 78 ;
Standard deviation = 14
Step-by-step explanation:
Given that:
Mean score = 68
Standard deviation = 14
When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.
Constant Added score = 10
The mean of scaled test score will be:
Mean score + constant added score
68 + 10 = 78
The standard deviation remains unchanged ; Hence, standard deviation = 14
This equation if finding x would be 88
