Answer:
hmm bro it's kinda blurry can u retake the pic? i will help u to solve it
Let's solve your equation step-by-step.
1/3x^2=16
Step 1: Divide both sides by 1/3.
1/3x^2 ÷ 1/3 = 16 ÷ 1/3
x^2=48
Step 2: Take square root.
x=±√48
x=4√3 or x=−4√3
Answer: x=4√3 or x=−4√3
Answer:
mean=sum of all observations/no.of observations
mean =23+15+6+5+6/5
mean=55/5
mean=11
population mean =11
hope this answer helps
Answer:
Step-by-step explanation:
A) Use the distributive property to eliminate parentheses. Then combine like terms. (The only "like terms" are the constants.)
... = 12 +3·2y +3·(-3) . . . use the distributive property to multiply each term in parentheses by the factor 3 outside those parentheses
... = 12 +6y -9 . . . . . . . . simplify
... = 6y + (12 -9) . . . . . . group like terms together
... = 6y + 3 . . . . . . . . . . simplify
___
B) Look for factors of each term that are also found in the other term.
... 18b has factors 3×6×b
... 12 has factors 2×6
The only common factor is 6, so we factor that out using the distributive property.
... 18b -12 = 6(3b -2)

<em>Comment on factoring</em>
For factoring problems, it helps immensely if you know your times tables and some of the rules for divisibility. (Even numbers are divisible by 2, numbers ending in 0 or 5 are divisible by 5, numbers whose sum of digits is divisible by 3 are divisible by 3, for example.)
