Answer:
The answer is D) 60
Step-by-step explanation:
1 * 60 * 60 = 3600 (seconds in 1 hour)
3600 * 6 = 21600 (seconds in 6 hours)
3600 * 0.4 = 1440 (seconds in 0.4 hour)
21600 + 1440 = 23040 (6 hours + 0.4 hours)
your answer is 23040
(60 / - 20 ) x 100% = 300%
Answer:
35.32
Step-by-step explanation:
The regression equation usually demonstrated as
y=a+bx.
In the above equation y is the dependent variable, x is the independent variable, a is the intercept of regression line and b is the slope of regression line.
The given regression equation is
y^=0.06x+14.2
The predicted value of y can be computed by simply putting the value of x in above equation.
So,
y^=0.06(352)+14.2
y^=21.12+14.2
y^=35.32
Thus, the predicted value of y for x=352 is 35.32.
Answer:
18/5 miles
Step-by-step explanation:
let d be the mountain dist path
upward biking
x miles - 1 hr
d 45 mins
3x/4 = d
riding down
x+3 - 60 min
d. - 20
(1/3)(x+3) = d
(x+3)/3 = 3x/4
4x+12 = 9x
x = 12/5
d =( 12*3)/(4*5)= 9/5
upward+downward = 2*(9/5) = 18/5
