Graphic DesignWorks ships the t-shirts it makes in boxes that measure 20 in x 18 in x 15 in. The company rents a storage space t

ioda

Answer:

D) 1,036,800 boxes

Step-by-step explanation:

The volume of a box is ...

(20 in)(18 in)(15 in) = 5400 in^3

The volume of the storage space is ...

(300 ft)(240 ft)(45 ft) = 3,240,000 ft^3

Then the number of boxes that will fit in the storage space is ...

(3240000 ft^3)(1728 in^3/ft^3)/(5400 in^3/box) = 1,036,800 boxes

In order to test for the significance of a regression model involving 3 independent variables and 47 observations, the numerator

matrenka [14]

Answer:

The correct option is C

Step-by-step explanation:

From the question we are told that

The number of independent variables is $n = 3$

The number of observation is $z = 47$

Since n is are independent variables then their degree of freedom is 3

The denominator(i.e z) degrees of freedom is evaluated as

$Df(z) = z - (n +1)$

$Df(z) = 47 - (3 +1)$

$Df(z) = 43$

So for the numerator (n) the degree of freedom is Df(n) = 3

So for the denominator(i.e z) the degree of freedom is Df(z) = 43

Compute (3+4i) +(7 − 20i).

Sveta_85 [38]

Answer:

10 -16 i

Step-by-step explanation:

given,

(3+ 4 i) + (7 − 20 i)

for the given complex number

if the number is added of subtracted the real part will add or subtract to the real part and imaginary will add or subtract to the imaginary part.

now

= (3+ 4 i) + (7 − 20 i)

= (3 + 7) + (4+(-20)) i

= 10 + (-16) i

= 10 -16 i

so, the given answer will be 10 -16 i
