Answer:
solve. 8^2x-3 =1/16 ----- Converting to base 2 6x - 9 = - 4 ----- Bases are equal and so are their exponents 6x = 5

Answer:
Carrie's slope value is correct.
Step-by-step explanation:
The least square regression line is:
Here is the slope of the line.
The formula to compute the slope is:
Here = standard deviation of <em>x</em> and = standard deviation of <em>y</em>.
It is provided that the standard deviation of <em>x</em> and <em>y</em> are equal.
So the slope of the regression line is:
Thus, if the standard deviation of <em>x</em> and <em>y</em> are equal the slope of the line is same as the correlation coefficient.
The correlation coefficient is a measure used to determine the strength of the linear relationship between the variables.
It ranges from -1 to 1.
Carrie's slope value was 0.50 and Ryan's slope value was 2.
Since -1 ≤ r ≤ 1 the value of slope cannot be 2.
Thus, Ryan's slope value is incorrect.
Answer:
Mary has 12 marbles.
Step-by-step explanation:
In order for 5/6 to equal 10, we would have to make groups of twos to represent the striped marbles. In this case, we would have 5 twos, not only to make the ten but also to make the 5/6. Then, to finally get our remaining 1/6, we would add one more group of two, making 12.
