Answer:
The total number of cubes in each shape will alternate between even and odd.
The length of each shape will alternate between even numbers and odd numbers
Step-by-step explanation:
I have drawn a picture of the cubes below.
The cubes for Step 1 are black.
Those added in Step 2 are pink.
Each step has cubes of a different colour.
The total number of cubes in each shape (Column 4 in the table) alternates between even and odd.
The length of each shape (Column 3 in the table) alternates between even and odd.

Answer:
A. 4.8 units
Step-by-step explanation:
Segment ZX can divide the figure into two right triangles. Then angle XZY is 136°/2 = 68°. The tangent relation tells you ...
Tan = Opposite/Adjacent
tan(68°) = XY/r
r = 12/tan(68°) ≈ 4.848 ≈ 4.8
The radius of the circle is about 4.8 units.

Step-by-step explanation:
Answer:
x equals -7 and x equals 5 our function is discontinuous
Step-by-step explanation:
x^2+7x-5x-35=0
x(x+7)-5(x+7)=0
(x+7)(x-5)=0
(x+7)=0\text{ or }(x-5)=0
x=-7\text{ or }x=5
Answer:
Probability distribution B
Step-by-step explanation:
Probabilities cannot be negative numbers. This means we can exclude distributions A and C.
Probability can be a maximum of 1.0. This means we can eliminate distribution D.
This leaves distribution B.
We can double check by finding the sum of the distribution. The sum of a probability distribution is 1.0. Adding these probabilities together, we have
0+0.45+0.16+0.39 = 1.00
B is correct.
