Answer:
4th option
Step-by-step explanation:
6/sin(65) = 5/sin(x)
or, 6×sin(x) = 5×sin(65)
or, sin(x) = 5×sin(65)/6
or, x = arcsin(5×sin(65)/6)
Answer:
85
Step-by-step explanation:
The correlation coefficient relates the standarized values of the midterms a final score in this way:

where y is the final score that needs to be found, y^ is the average score on the finals, sy is the standar deviation for the scores on the finals, x is the midterm score, x^ is the average score on the midterms and sx y the standard deviation of the scores on the midterms.
If we issolate y on the equation and solve with the data we have, we get that:
r* \frac{x - x^}{sx}[/tex] = 0.5 *
= 1
y = 75 + 1*10 = 85
This means the predicted final score will be 85.
Answer:
the answer is 3GB
Step-by-step explanation:
30-21=9 9/3 = 3
2 hr 15 min = 2

hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 =
126 miles
"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
