Answer:
f(-3) = 44
Step-by-step explanation:
f(x) = 2x² - 5x + 11
Substitute the value.
f(-3) = 2(-3)² - 5(-3) + 11
Raise -3 to the power of 2.
f(-3) = 2(9) - 5(-3) + 11
Multiply 2 and 9.
f(-3) = 18 - 5(-3) + 11
Multiply -5 and -3.
f(-3) = 18 + 15 + 11
Add 18 and 15.
f(-3) = 33 + 11
Add 33 and 11.
f(-3) = 44

Answer:
(0.392 ; 0.508)
Step-by-step explanation:
Given that :
p = 45% = 0.45
α = 1 - 90% = 0.1
Zα/2 = Z0.01/2 = Z0.05 = 1.645 (from Z standard table).
Using the relation :
p ± Z0.05*sqrt((p(1-p))/n)
p ± 1.645 * sqrt(0.45(0.55)/200)
p ± 1.645 * sqrt(0.0012375)
p ± 1.645 *0.0351781
0.45 - (1.645 * 0.0351781) = 0.3921320255
0.45 + (1.645 * 0.0351781) = 0.5078679745
(0.392 ; 0.508)
Answer:

Step-by-step explanation:
Given inequality is 
Simplifying the inequality by rearranging the terms:

=> 
=> 
=> 
So the given inequality can be simply expressed as 
Hence x can take all values in the domain which are less than 2.
