Answer:
8x^3-7x^2-11x+9
Step-by-step explanation:
(8x^3-5x-1)-(7x^2+6x-10)
remove unnesasary ( )
8x^3-5x-1 -(7x^2+6x-10)
the distribute
8x^3-5x-1 -7x^2-6x+10
combine like terms
8x^3-11x+9-7x^2
use the communative property to reorder the equation
8x^3-7x^2-11x+9
Answer:
0.0537
Step-by-step explanation:
This follows a binomial distribution with : n
Number of trials 'N' = 12 ; Probability of success (difference between speakers) 'p' = 1/2 or 0.5 ; Probability of failure (no difference b/w speakers) = 1/2 or 0.5 ; No of success 'r' = 3
P (X = 3) = 
= 12C3 (0.5)^3 (0.5)^9
0.0537
Answer:

Step-by-step explanation:
The multiplicative inverse of a number n is 
The product of the number and its multiplicative inverse = 1
n ×
= 1
Thus the multiplicative inverse of
is
= 
Answer: 1 over 2 (1/2)
Simplify 2 over 8 to get 1 over 4. Now you have 1 over 4 divided by 1 over 2. Whenever you divide with fractions you flip the fraction and multiply . So it becomes 1 over 4 multiplied by 2 over 1.
2/8 (divided by) 1/2
1/4 (divided by) 1/2
1/4 x 2/1
= 1/2
Answer:
A. 6.0
Step-by-step explanation:
We have been given that the the inside diameter of the part on the paper is 1.50 inches.
We have been given that scale is 4:1 for actual size to drawing side.

Upon substituting 1.50 in our given proportion, we will get:




Therefore, the actual size is 6.0 inches and option A is the correct choice.
