Answer:

Option A. 64,500

Explanation:

1. First, calculate the number of hits had during the month, by difference:

50,165 hits - 7,278 hits = 42,887 hits

2. Round the result to obtain an approximation = 43,000 hits

3. Multiply by the time that each lasted:

43,000 hits × 1.5 min/hit = 64,500 minutes.

Hence, the answer is the option A.

What is the zero of the function below? f(1) = 3v1 + 3 - 6

Reika [66]

Answer:

v1 = 1

Step-by-step explanation:

Solve for v1:

3 v1 - 3 = 0

Add 3 to both sides:

3 v1 + (3 - 3) = 3

3 - 3 = 0:

3 v1 = 3

Divide both sides of 3 v1 = 3 by 3:

(3 v1)/3 = 3/3

3/3 = 1:

v1 = 3/3

3/3 = 1:

Answer: v1 = 1

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

$p = 100 - 56.3$

$p = 43.75$ %
