Answer:

Step-by-step explanation:

Use the normcdf( function on a basic calculator as follows:

normcdf(-1000, 9750, 12000, 4500).  Result:  0.307.  This is the area under the standard normal curve to the left of 9750.

But we want the area  under the standard normal curve to the right of 9750, so we subtract this 0.307 from 1.000, obtaining the desired result:  0.693.  This roughly corresponds with the last of the given possible answers, 69.15%.

The volume of a box(V) varies directly with its length(l). Using k for the constant of proportionality, express the relationship
pochemuha

Answer: V = L (k)

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

  • <em>Volume of a box = V </em>
  • <em>Length = l </em>
  • <em>Constant of proportionality = k</em>

We know that the volume of the box (V) varies directly with its length (l).

So, the expression for the volume is:

V = L (k)

Ona took a random sample of 20 soccer teams across Europe. She tracked the average number of goals
anygoal [31]

The predicted number of wins for a team that averages 1.5 goals per game will be 17 according to the regression model.

From the table given, the linear regression model for the data can be expressed as :

  • y = 14.02x - 3.64 ; where ;
  • y = Predicted number of wins ;
  • x = average number of goals per match ;
  • slope = 14.02 ;
  • Intercept = - 3.64

<u>The Number of wins for a team which averages 1.5 goals per match can be calculated thus</u> :

Average goals per match, x = 1.5

Substitute x = 1.5 into the equation :

y = 14.02(1.5) - 3.64

y = 17.39

y = 17 (nearest whole number)
