306
Step-by-step explanation:
18x17=306
Answer:
Step-by-step explanation:
Question (1)
x² + 10x + 12
= x² + 2(5x) + 5² - 5² + 12
= [x² + 2(5x) + 5²] - 5² + 12
= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]
= (x + 5)² - 13
Question (2)
y² - 6y - 15
= y² - 2(3y) - 15
= y² - 2(3y) + 3² - 3² - 15
= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]
= (y - 3)² - 3²- 15
= (y - 3)² - 9 - 15
= (y - 3)² - 24
Answer:
D. +3.82
Step-by-step explanation:
The computation of the test static for this test is shown below:
Data provided in the question
= $8,745
= $8,500
= $1,200 and n = 350
Now based on the above information, the test static for this test is


= 3.82
= +3.82
Hence, the test static for this test is +3.82
We simply applied the above formula so that the correct value could come
And, the same is to be considered
The answer is 45 when you substitute all the variables in
