√28 = 2√7 or roughly 5.29
Answer:
$3.9K is the profit made from 100 TVs
Step-by-step explanation:
Step-by-step explanation:
the profit is defined by
Profit=Gain-cost
In this case (F-g)(100)= is the profit to sell 100 television and is calculated
F(x)-g(x)=4x+5000-(20x-500)=4x-20x+5000+500=-16x+5500=-16*(100)+5500=3900
3900=3.9k
Answer:
x^2 - x - 12 (this is the second answer choice)
Step-by-step explanation:
Multiply (x + 3)(x - 4) and simplify the result:
x^2 - 4x + 3x - 12, or x^2 - x - 12 (this is the second answer choice)
Answer:
( 0.742, 0.849 )
Step-by-step explanation:
sample size = 220
number of voters with positive response ( i.e. number of voters who believe the government is doing right ) = 175
<u>Calculate the 95% confidence interval</u>
P = 175 / 220 = 0.796
the 95% confidence interval = ( 0.796 ± 0.054 )
attached below is the detailed solution
Answer:
POLYNOMIAL is a 10-letter word
Step-by-step explanation:
A polynomial is such an expression.
Virtually any kind of algebraic expression is made by adding or subtracting terms, grouping them, applying functions to them, or dividing them. (A term is already a product; increasing the number factors doesn't change that.)
A polynomial is a special kind of sum-of-terms expression involving terms that are non-negative integer powers of a variable.
