The range of the function on the graph is all real numbers greater than or equal to 2 because the range of a function is what the value of y could be, and y begins at 2 and keeps increasing indefinitely.
Hope this helps!
Answer:
0
Step-by-step explanation:
Any number multiplied by zero is equal to zero. So if the product is zero, one factor must be zero. Since you already have a nonzero factor, the other must be zero.
Answer:
Step-by-step explanation:
(5+(-4))/2 = 1/2 or 0.5
(-7 + 6)/2 = -1/2 or -0.5
the solution is D
(0.5, -0.5)
Answer: [a] 95% confidence interval = 4.4 < Ẍ <9.2
[b] margin of error = ± 2.4
Step-by-step explanation:
here let us carefully look into this problem,
from the question, we have that Ẍ = 6.8, and SE = 1.2
let us begin
(a). asked to calculate the 95% confidence interval we have;
95% C.I = Ẍ ± 2 (SE) = 6.8 ± 2(1.2) = 6.8 ± 2.4
95% C.I = (4.4, 9.2)
this gives the confidence interval to be (4.4 < Ẍ < 9.2).
(b). the error margin is ± 2.4, which implies that our estimate of 6.8 pounds is within 2.4 pounds of the true mean weight gain for the population.
cheers i hope this helped a great deal !!1
we can simply just draw them, notice it is a vertical line
