A container is shaped like a rectangular prism and has a volume of 72 cubic feet. Give four different set of measurements that c

dimaraw [331]

Answer:

The formula for the volume of a prism is V = Bh

where,

B is the base area

h is the height.

Since, the base of the prism is a rectangle, therefore, volume of a rectangular prism = (L * B) * h

Assumptions:

Length, L and Width, B cannot be the same.

h = 4 ft

B = 2 ft

L = 9 ft

h = 4 ft

B = 3 ft

L = 6 ft

h = 6 ft

B = 2 ft

L = 6 ft

h = 2 ft

B = 2 ft

L = 18 ft

irakobra [83]

Answer:

A. $y=-8.583x+475.215$

Step-by-step explanation:

We are given,

The table representing the closing prices of stock for the last five days is,

Day Value

1 472.08

2 454.26

3 444.95

4 439.49

5 436.55

Using the linear regression calculator, we have that,

<h3>The linear equation that best fits the data is $y=-8.583x+475.215$ </h3>

Thus, option A is correct.

we know that

the car gets 18 miles per -----------> 1 gallon of gasoline

for 543 miles ---------------------> x gallons of gasoline

by proportion

543/18=x/1---------->x=543/18------->x=30.17 gallons

therefore

The probability that a can of paint contains contamination is 3.23%, and the probability of a mixing error is 2.4%. The probabil

stich3 [128]

Answer:

4.6%.

Step-by-step explanation:

The probability that a can of paint contains contamination(C) is 3.23%

P(C)=3.23%

The probability of a mixing(M) error is 2.4%.

P(M)=2.4%

The probability of both is 1.03%.

$P(C \cap M)=1.03\%$

We want to determine the probability that a randomly selected can has contamination or a mixing error. i.e. $P(C \cup M)$

In probability theory:

$P(C \cup M) = P(C)+P(M)-P(C \cap M)\\P(C \cup M)=3.23+2.4-1.03\\P(C \cup M)=4.6\%$

The probability that a randomly selected can has contamination or a mixing error is 4.6%.

How do you find measures using postulates and theorems?

Dennis_Churaev [7]

Just use the definitions and put them in order to explain the problem.m. for instance. why are angles a and b vertical angles? they are adjacent and they are supplementary.
