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

$p = 100 - 56.3$

$p = 43.75$ %

A force of 76 N is applied to an area of 490 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer.

kolezko [41]

Answer:

Given

Hope it helps

Step-by-step explanation:

Pressure is the force per unit perpendicular area over which the force is applied

p=F/A

Where f is force and a is area

So P

= F/A

= 76N / 0.049m2

= (76/0.049) Nm2

= 76000/49

= 1551.02

Or 1551 N/m2

Answer:

It will be compressed vertically

Step-by-step explanation:

y = Cf(x) 0 < C < 1 compresses it in the y-direction

Since we are multiplying by 1/4 it will compress it by 1/4 in the y direction
