week 23 is the answer if this did not help or if im wrong sorry
X² + 10x + 25 = 16
x² + 10x + 25 - 16 = 0
x² + 10x + 9 = 0
(x + 1)(x + 9) = 0
x(x+9) + 1(x+9) = 0
x² + 9x + x + 9 = 0
x² + 10x + 9 = 0
(x + 1) = 0
x = -1
(x + 9) = 0
x = -9
Answer: t = 10
Step-by-step explanation:m
Given that; n₁ = 10, n₂ = 10
ж₁ = 50, ж₂ = 30
Sˣ₁ = 20, Sˣ₂ = 20
Now using TEST STATISTICS
t = (ж₁ - ж₂) / √ ( Sˣ₁/n₁ + Sˣ₂/n₂ )
so we substitute our figures
t = ( 50 - 30 ) / √ ( 20/10 + 20/10 )
t = 20 / √4
t = 10
Hey there! I'm happy to help!
The domain is all of the x-values of a relation and the range is all of the y-values. When you write them out, you order the numbers from least to greatest and put it in brackets.
The domain of our relation is the x-values of these points, which are 11, 9, 7, and 5. The domain is {5,7,9,11}.
The range is the y-values, which are 1, 2, 3, and 4. So, the range is {1,2,3,4}.
Now you can find the domain and range given a few ordered pairs!
Have a wonderful day!
