Answer: X=44
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
Answer:
a^2b(7 + 10b + 14b^2)
Use wolframalpha for math questions, or photomath!
To solve this, factor out a^2b from the expression.
<h3>Use the distributive property to simplify the expression:</h3><h3>(-1)(4 - c) = -4 + c</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
(-1)(4 - c)
We have to use the distributive property to simplify the expression
<em><u>By distributive property,</u></em>
a( b + c) = ab + ac
where, "a" is distributed to terms inside the bracket
Therefore, from given,
Thus the expression is simplified using distributive property
Answer:
b.
The mean increases by $1,696.30, the median increases by $79.
Step-by-step explanation:
THe mean of the 7 wins is given by
: 767+477+340+680+464+207+635/7
this equals: 510,
the new mean will be
767+477+340+680+464+207+635 +10000/8
which comes out to be:
1696.25
This is bigger than the previous mean by :
1186.25
Now the median of the first 7 observations would be:
477
of the 8 observations it woulf be
477 + 635/2
which comes out to be 79
