Number 13 explain......

Marat540 [252]

The slope is 2 and the equation of the line is y = mx+b with m =2

Then the equation becomes: y = 2x+b. How to calculate b?
Since this line passes through the point (-3 , 4), we replace x with -3 and y=4

4= 2.(-3) + b
4 = - 6 + b
and b= 10. The final equation is : y = 2x + 10 (answer a)

wind resistance varies jointly as an objects surface area and velocity. if an object traveling at 55 miles per hour with a surfa

nikdorinn [45]

Answer:

25 miles per hour

Step-by-step explanation:

Given

$W = Wind\ resistance$

$A = Surface\ Area$

$V = Velocity$

The joint variation can be represented as:

$W\ \alpha\ A*V$

Where:

$V = 55; A = 20; W = 220$

Required

Find V, when: $A = 55; W = 275$

We have:

$W\ \alpha\ A*V$

Express as an equation

$W= k *A*V$

Where k is the constant of variation

Make k the subject

$k = \frac{W}{A*V}$

When: $V = 55; A = 20; W = 220$

We have:

$k = \frac{220}{20 *55 }$

$k = \frac{220}{1100}$

$k = 0.2$

When: $A = 55; W = 275$

We have:

$k = \frac{W}{A*V}$

Substitute: $A = 55; W = 275$ and $k = 0.2$

$0.2 = \frac{275}{55 * V}$

Make V the subject

$V= \frac{275}{55 * 0.2}$

$V= \frac{275}{11}$

$V= 25$

The correlation between height and weight for a certain breed of plant is found to be 0.75. What percentage of the variability i

WINSTONCH [101]

Answer:

The percentage of the variability in plant weight is NOT explained by height is

$p = 43.75$ %

Step-by-step explanation:

From the question we are told that

The correlation between height and weight is $r = 0.75$

Generally the R-Squared between height and weight is mathematically represented as

$R - square = r^2$

substituting values

$R - square = 0.75^2$

$R - square = 0.563$

This R-Squared tells us the percentage of plant weight is accounted by height

and from the calculation we see that it is 56.3%

Now the percentage of plant weight that is not accounted by height is

$p = 100 - 56.3$

$p = 43.75$ %
