Answer:

No, his inference is not valid

Step-by-step explanation:

the data shown represents the statistic of 100 people's preferred ways to view movies in total

out of that 30/100 people prefer to watch in theatre.

trent inferences that out of 400 people 300 would prefer to watch in theatre another way to write this is 300/400

if we multiply the data we're given so that the denominators match Trent's inference. The data tells us that 120/400 would prefer to watch in theatre, so his inference is not valid.

A 3-dimensional shape is made of 36 unit cubes, without any gaps. What is the volume of the shape?
fomenos

Answer:

36 unit

Step-by-step explanation:

The number of unit cubes in the shape = 36 unit cubes

The dimension (volume) of each cubes = 1 unit³

The type of shape = 3-dimensional

The arrangement of the cubes in the shape = Without gaps

The volume of a 3-dimensional shape made of a number of unit cubes without gaps is equal to the sum of the unit cubes

Therefore;

The volume of the 3-dimensional shape that consists of 36 unit cube, V = (1 + 1 + 1 +...+ 1) unit³ = 36 unit³

The volume of the 3-dimensional shap³e, V = 36 unit³

Please help- A bakery sells cakes for $18 each and pies for $15 each. Last weekend the bakery sold 118 total items and earned $1
Sati [7]

Answer:

64 pies sold

Step-by-step explanation:

x = number of cakes sold

y = number of pies sold

Last weekend the bakery sold 118 total items

x + y = 118

Last weekend the bakery earned $1,932.

18x + 15y = 1,932.

Get rid of one of the terms, in this case x.

x + y = 118 becomes

18x + 18y = 2124

Subtract the equations from each other

(18x - 18x) + (18y - 15y) = 2124 - 1932

3y = 192

y = 64

Subsititue y into the orginal qeuation to solve for x and check it's right.

x + 64 = 118

x = 118 - 64 = 54

18(54) + 15(64) = 1932
