Answer:

550 grams

Step-by-step explanation:

From the given knowledge we can set up 2 equations:

25x + y = 10.3

10x + y =4.45

where x represents the amount of balls, and y represents the weight of the basket.

We can solve one equation for y and then plug that into the other equation.

Solve 25x + y = 10.3 for y:

25 x + y = 10.3

25x + y + (−25x) = 10.3+ (−25x)  (Add -25x to both sides)

y= −25x +10.3

We can plug in this value of y into the other equation and solve for y

Substitute−25x+10.3 for y in 10x + y = 4.45:

10x + y = 4.45

10x + (−25x) + 10.3 = 4.45

−15x + 10.3 = 4.45 (Simplify both sides of the equation)

−15x + 10.3 + (−10.3) = 4.45 + (−10.3) (Add -10.3 to both sides)

−15x = −5.85 (Divide both sides by -15)

x=0.39

Now we know what the weight of each ball is.  We just need to substitute .39 for x to find y to get the weight of the basket.

Substitute 0.39 for x in y = −25x + 10.3:

y = −25 x + 10.3

y = (−25)(0.39) + 10.3

y = 0.55 (Simplify both sides of the equation)

So the basket weight .55kg, or 550 grams

Using the mean concept, it is found that the mean difference between the call times and the  company's average call time is given by:

  • C. 0.4

<h3>What is the mean?</h3>
  • The <em>mean </em>of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem:

  • The four observations are the differences between the time of each phone call and the average time.
  • They are: {-2.32, -1.55, 4.79, 0.68}

Hence, the mean difference is:

M = \frac{-2.32 - 1.55 + 4.79 + 0.68}{4} = 0.4

Hence, option C is correct.
