The range of the given relation is D. R = {-1, 3, 5, 8}.

Step-by-step explanation:

Step 1:

The range of a relation is the second set of values while the domain constitutes the first set of values.

There are 4 given relations with two sets of values so there would be 4 domain values and 4 range values.

Step 2:

The range of (1, -1) = -1,

The range of (2, 3) = 3,

The range of (3, 5) = 5,

The range of (4, 8) = 8.

Combining these values we get the range as {-1, 3, 5, 8} which is option D.

How much surface area would be lost if you glued three 4-cm cubes together to make a rod that is three cubes long and one cube w

Kipish [7]

Answer:

Part 3) $SA=288\ cm^2$

Part 4) $64\ cm^2$

Step-by-step explanation:

Part 3) Calculate the total surface area of three 4 cm cubes

we know that

The surface area of a cube is equal to the area of its six square faces

$SA=6b^2$

The surface area of three cubes is equal to the area of its 18 square faces

$SA=18b^2$

where

b is the length side of the square face

In this problem

$b=4\ cm$

The surface area of three cubes is

$SA=18b^2$

substitute the given value

$SA=18(4)^2$

$SA=288\ cm^2$

Part 4) How much surface area would be lost if you glued three 4-cm cubes together to make a rod that is three cubes long and one cube wide?

In this case the total surface area of the three glued 4-cm cubes is equal to the area of its 14 square faces

The surface area lost is equal to

$18b^2-14b^2=4b^2$

substitute

$4(4)^2=64\ cm^2$

What is the difference between law and scientific law.

igomit [66]

Answer:

A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. ... However, Newton's law doesn't explain what gravity is, or how it works.

Nina [5.8K]

Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)

08.01)Marlow wants to know how many students in his school enjoy watching the TV news. He asks all 27 students in his art class

Inga [223]

Part 1 : Marlow wants to know how many students in his school enjoy watching the TV news. He asks all 27 students in his art class and finds that 30% of his classmates enjoy watching the TV news. He claims that 30% of the school's student population would be expected to enjoy watching the TV news. Is Marlow making a valid inference about his population?

No, it is not a valid inference because he asked all 27 students in his art class instead of taking a sample from the school

No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

Yes, it is a valid inference because he asked all 27 students in his art class

Yes, it is a valid inference because his classmates make up a random sample of the students in the school

Answer = The correct answer is B because Marlow was supposed to ask random kids and they were not suppose to be in his class.

Part 2 : Carl takes a random sample of 100 students in his school and finds that 72% of the sample prefers pizza over burgers. There are 1,500 students in the school. Based on the sample proportion, how many students in the school would be expected to prefer pizza over burgers?
