Answer:
B. $ 3094.01
Step-by-step explanation:
Given observations are,
$2894.21, $1777.15, $2144.77, $4096.37, $4046.29, $1786.37, $3296.69, $4086.27, $2784.22
Number of observations = 10,
Sum of the observations = 2894.21+1777.15+2144.77+4096.37+4046.29+1786.37+3296.69+4086.27+2784.22+4027.79 = 30940.13,
Hence,




Option 'B' is correct.
Answer:
a=4
Step-by-step explanation:
Add like terms. You get 7a-6=3a+10. Subtract 3a from 7a and get 4a. Add 6 to both sides and get 16. After this, divide by 4.
Step-by-step explanation:
Given AB = CD
<em>ADDING</em><em> </em><em>BC</em><em> </em><em>ON</em><em> </em><em>BOTH</em><em> </em><em>SIDES</em><em> </em>
<em>WE</em><em> </em><em>GET</em>
<em>AB</em><em>+</em><em>BC</em><em>=</em><em>CD</em><em>+</em><em>BC</em>
<em>THEREFORE</em><em> </em><em> </em><em>AC</em><em> </em><em>=</em><em>BD</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>HAVE</em><em> </em><em>A NICE DAY</em><em>!</em>
The answer to the question would be 6
Answer:
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
