If those are the possible answers i'm pretty sure you need to have a group of numbers you extract the mean from for example form the numbers 56, 77, 65, 87, and 99 the mean of the numbers would be 77 so once i have those we can figure it out
4 + 3 × x should be right
Answer:
a = 1
b = - 1
Explanation:
To know the values of a and b, we need to solve the following equation:
So, replacing cos(-π/4) by √2/2 and sin(-π/4) by -√2/2, we get:
Applying the distributive property:
Therefore, we can complete the equation as:
It means that a = 1 and b = - 1.
Answer:
no because the parenthesizes means your multiplying
Step-by-step explanation:
V= 1/3(b)(w)(h)
V ≈ 66.7 ft^3
12.5•16 = 66.67
