Answer:
This is true
Step-by-step explanation:
Because a distribution of sample means is as the set of means from all the possible random samples of a specific size, selected from a specific given population.
Step-by-step explanation:
the temperature fell 24°F in 7 hours.
so, when it had -2°F at 7pm, it had 24° more 7 hours before that.
that is 22°F at 12pm (noon).
Answer:
2
Step-by-step explanation:
4y = 2x + 8
First get the equation in slope intercept form y= mx+b where m is the slope and b is the y intercept
Divide each side by 4
4y/4 = 2x/4 +8/4
y = 1/2x +2
The slope is 1/2 and the y intercept is 2
The rate of deceleration is equal to 25 m/s / 6 s = 25/6 m/s^2.
(a) The string should be angled in such a way that the horizontal acceleration is equal to 25.6 and the vertical acceleration is equal to gravitational acceleration. Using trigonometry,Angle from the vertical = arctan(25/6 / 9.8) = 23.03 degrees.
(b) Since the car is decelerating, one end of the string attached to the car is pulled back and because of the inertia of the object it is goes on the opposite direction and so the object moves toward the windshield.

Answer:
Step-by-step explanation:
y(x) = (1/8)^x
y(1/3) = (1/8)^(1/3) = 0.5
