Answer:

They are not parallel

Step-by-step explanation:

original equation

10x + 3y = -3

subtract 10x

3y = -10x - 3

divide by 3

y = -10/3x - 1

original equation

5x - 4y = -3

subtract 5x

-4y = -5x-3

divide by -4

y = 5/4x + 3/4

the slopes are not equal to each other (5/4x and -10/3x) so they are not parallel

On a hike, Parker noticed that the temperature at the base of a mountain was 64°F. At a point on the mountain that was 2,000 fee

MArishka [77]

Answer:

Step-by-step explanation:

Rate of change of Temperature with height can be given by:

$\frac{dT}{dh} = \frac{T_{top} - T_{bottom}}{h_{top} - h_{bottom} }$

$\frac{dT}{dh} = \frac{58 - 64}{2000} = -0.003 Fahrenheit/ft$

Please help me with the question

mars1129 [50]

(i) The mean is

$\displaystyle E(X) = \sum_x x \, P(X = x) \\\\ E(X) = 1\cdot0.175 + 2\cdot0.315 + 3\cdot0.211 + 4\cdot0.092 + 5\cdot0.207 \\\\ \boxed{E(X) = 2.839}$

The variance is

$V(X) = E((X - E(X))^2) = E(X^2) - E(X)^2$

Compute the second moment $E(X^2)$ :

$\displaystyle E(X^2) = \sum_x x^2 \, P(X = x) \\\\ E(X) = 1^2\cdot0.175 + 2^2\cdot0.315 + 3^2\times0.211 + 4^2\times0.092 + 5^2\times0.207 \\\\ E(X^2) = 9.997$
