Alice’s chicken coop (cage) has a total volume of 742 cubic feet (ft3). Use the fact that 1 foot is approximately equal to 0.304

skelet666 [1.2K]

Answer:

21.01 cubic metres

Step-by-step explanation:

We have to find the value of 1 cubic foot and then convert to cubic metre.

1 foot = 0.3048 m

1 cubic foot = $(0.3048)^3$ = 0.02832 cubic metre

A volume of 742 cubic foot will therefore be:

742 * 0.02832 = 21.01 cubic metres

The volume in cubic metres is 21.01 cubic metres

What is the value of x?

yulyashka [42]

Answer:

An x-coordinate is the x value in an ordered pair, which is just two mathematical objects, such as numbers, paired together. ... For instance, in the ordered pair (2,5), the x-coordinate would be '2. ' This value tells you how far a point is from the origin, or starting point, in the x direction on a 2-dimensional graph.

A random sample of 25 fields of spring wheat has a mean yield of 27.6 bushels per acre and standard deviation of 5.69 bushels pe

ale4655 [162]

Answer:

Step 1 z(c) = 2,323

CI = ( 25 ; 30,2 )

Step-by-step explanation:

Normal Distribution:

Sample size n = 25

Sample mean μ = 27,6

Sample standard deviation s = 5,69

CI = 98 % then α = 1 - 0,98 α = 0,02 α/2 = 0,01

From z-table we don´t find z (score) for 0,01 directly, we need to interpolate between z = 2,32 and z = 2,33

For 0,0099 z score is 2,33

for 0,0102 z score is 2,32

Δ 0,0003 0,01

Then by rule of three

for Δ 0,0003 ⇒ 0,01

for Δ (0,01- 0,0102) ⇒ x

0,0003 0,01

0,0002 x

x = 0,0067

then z (score for 0,01) = 2,33 - 0,0067 z(c) = 2,3233

round to three decimal places z(c) = 2,323

Step 2:

CI = μ ± z(c) * s/√n ⇒ 27,6 ± (2,323 * 5,69)/5

CI = 27,6 ± 2,6436

round to one decimal place

CI = 27,6 ± 2,6

CI = ( 25 ; 30,2 )
