Answer:
50,000 fifty-thousand
Step-by-step explanation:
Just use a calculator
The sum of your data set is 23.8333333333.All you have to do is add them all together and then divide by 6, which is the number of numbers there are.
8+13+17+26+32+47=143
143/6+23.8333333333
Answer:
x=0
x=7
Step-by-step explanation:
x²-x-1=6x-1
x²-x-1-6x+1=0
x²-7x=0
x(x-7)=0
x=0
x-7=0
x=7
Answer:
Step-by-step explanation:
36x^2-49
this closely matches the binomial formula of (a+b)*(a-b)=a^2-b^2
so we know:
a^2=36x^2
a=6x
b^2=49
b=7
so (a+b)*(a-b)=(6x+7)*(6x-7)=36x^2-49
