Step-by-step explanation:
add all numbers then divide by how many numbers
Answer:
6 yards by 11 yards
Step-by-step explanation:
Factors of 66 are ...
66 = 1·66 = 2·33 = 3·22 = 6·11
The last pair of factors differ by 5, so represent the solution to the problem.
The width of the parking lot is 6 yards; the length is 11 yards.

Step-by-step explanation:
-(2x+1)
-2x-1
write -2 in that bos and 1 after "-"
Answer:
Test statistic =1.30
Step-by-step explanation:
Given that you are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.
Men Women Difference
Sample size n 60 120
Proportion p_1, p_2 0.45 0.35 0.10
60 120 180
0.45 0.35 0.383333333
27 42 69
p = 0.3833
Std error for proportion difference = 
Test statistic = 
=
=1.30
Answer:
Step-by-step explanation:
y = x^2 - x - 2 is a quadratic function. It's easily factorable: y = (x + 1)(x - 2). Setting this result equal to zero yields the x-intercepts: -1 and 2. This matches the x-intercepts shown on the graph.
The axis of symmetry, x = -b/(2a), derived from the coefficients 1, -1 and -2 of this particular function, is x = 1/2. This x = 1/2 is also the x-coordinate of the vertex. To find the y-coordinate of the vertex, we evaluate y = x^2 - x - 2 at x = 1/2, obtaining:
y = (1/2)^2 - (1/2) - 2, or y = 1/4 - 1/2 - 2, or -2 1/4. This does not quite agree with the y value (-2) shown in the diagram, but is close.
