We know that 60 minutes = 1 hour and 1 mile = 5280 feet. We just need to multiply and simplify:
651 miles/hour = 651 *5280/60 feet/minutes = 651*88 feet/minutes = 57288 feet/minutes
The functions whose graphs include the point (16, 4) is y = x−12.
Option: D.
<u>Step-by-step explanation:</u>
To find the function that passes through the point (16,4).
Substitute the point in all the equations and equate the final values to find the correct equation.
A. y=2x.
Substitute (16,4).
4=2(16).
4≠32.
Thus the equation doesn't contains the point (16,4).
B. y=.
Substitute (16,4).
4=.
4≠ 256.
Thus the equation doesn't contains the point (16,4)
C. y=x+12.
4=16+12.
4≠28.
Thus the equation doesn't contains the point (16,4)
D. y=x−12.
4=16-12.
4=4.
Thus the equation contains the point (16,4)
E. y=14x.
4=14(16).
4≠224.
Thus the equation doesn't contains the point (16,4)
∴The functions whose graphs include the point (16, 4) is y = x−12.
Answer:
The 97% confidence interval would be from 108 to 165.
Step-by-step explanation:
Since the 78% confidence interval is from 87 to 133, to determine what the 97% confidence interval would be, the following calculations must be performed:
78 = 87
97 = X
97 x 87/78 = X
8.439 / 78 = X
108.19 = X
78 = 133
97 = X
97 x 133/78 = X
12.901 / 78 = X
165.39 = X
Thus, the 97% confidence interval would be from 108 to 165.
Answer:
D.
Step-by-step explanation:
A square root can't be evaluated if the number we want to find the square of is nagative.
