Answer:

-1/45

Step-by-step explanation:

Rewrite this as:

-2/9 - (-1/5), or -2/9 + 1/5

Here the LCD is (9)(5) = 45.  Rewriting the above expression, we get:

-10/45 + 9/45 = -1/45

Jerry is 8 years younger than Patricia. Six years ago, Patricia was 3 times as old as Jerry was then. Which system of equations
MissTica
<span>Jerry is 8 years younger than Patricia, so: (1): Jerry = Patricia - 8 Six years ago, Patricia was 3 times as old as Jerry was then, so: (2): (Patricia - 6) = (Jerry - 6)*3 Putting equation 1 in to equation 2 (Patricia - 6) = (Patricia - 8 - 6)*3 Patricia - 6 = 3Patricia - 42 36 = 2Patricia Patricia = 18 And so Jerry = 10</span>

If (x - 4) varies inversely as (y + 3) and x = 8 when y = 2, what is x when y = - 1?
denpristay [2]

Answer:

x=14

Step-by-step explanation:

If two values are inversely proportional, their product must be maintained. That way, if one value goes up, the other goes down by the same extent.

Therefore, if (x-4) and (y+3) vary inversely, their product will be the same for all values of x-4 and y+3.

Let x=8 and y=2 as given in the problem. Substitute values:

(8-4)(2+3)=(4)(5)=20

Hence, the maintained product is 20.

Thus, we have the following equation:

(x-4)(y+3)=20

Substitute y=-1 to find the value of x when y=-1:

(x-4)(-1+3)=20,\\(x-4)(2)=20,\\x-4=10,\\x=10+4=\boxed{14}

Suppose the correlation between height and weight for adults is +0.40. What proportion (or percent) of the variability in weight
Schach [20]

Answer:

We are given the correlation between height and weight for adults is 0.40.

We need to find the proportion of the variability in weight that can be explained by the relationship with height.

We know that coefficient of determination or R-square measures the proportion or percent of variability in dependent variable that can be explained by the relationship with independent  variable. There the coefficient of determination is given below:

R^{2}=r^{2}=0.40^{2}=0.16

Therefore, the 0.16 or 16% of the variability in weight can be explained by the relationship with height
