Answers

Answer 1

Answer:

:)

Step-by-step explanation:

quiz scores:

a. arrange them all from least to greatest to figure out the median first

your quiz: 15, 16, 17, 18, 19     middle # = 17        median = 17

friend's quiz: 12, 13, 17, 20, 20     middle # = 17       median = 17

now for mean add all of your quiz scores up and divide by how many #s

15 + 16 + 17 + 18 + 19 = 85 / 5 = 17          mean = 17

now your friend's:

12 + 13 + 17 + 20 + 20 = 82 / 5 = 16.4       mean = 16.4

mode is which number is used the most

your mode = you don't have a mode       your friend's mode = 20

b. you have a higher mean than your friend

world populations:

a. range is to subtract the smallest number from the largest

803 - 31 = 772

b. mean is adding it all up and dividing by how many numbers there are:

803 + 487 + 348 + 368 + 730 + 31 = 2767 / 6 = 461.17

median is arranging them in order and finding the middle #

31, 348, 368, 487, 730, 803

368 + 487 = 855 / 2 = 427.5

mean = 461.17

median = 427.5

mode = no mode

tomato plants:

a. range is subtracting the smallest from the largest

52 - 36 = 16

b. mean is adding all the #s and dividing by how many #s there are:

36 + 45 + 52 + 40 + 38 +41 + 50 + 48 = 350 / 8 = 43.75

median is the middle from least to greatest

36, 38, 40, 41, 45, 48, 50, 52

41 + 45 = 86 / 2 = 43

mean = 43.75

median = 43

mode = no mode

hope this helps! :)

The value of x in the equation is -18

How to solve the equation?

The equation is given as:

[tex]-\frac 23x - \frac{21}4 = \frac{27}4[/tex]

Add 21/4 to both sides of the equation

[tex]-\frac 23x = 12[/tex]

Multiply both sides by -3/2

[tex]x = -18[/tex]

Hence, the value of x in the equation is -18

Have you ever wondered what swims in the deepest parts of the world's oceans? Well, we just got a better idea about one mysterious creature of the deep ocean: the giant squid.Just recently a Japanese film crew managed to film a giant squid swimming in its natural habitat. They managed to lure it to their cameras with bait after many hours of waiting and searching two thousand feet below the surface of the Pacific Ocean.The giant squid is truly a giant. It can grow up to 50 feet in length, with tentacles making up most of this great length. For comparison, 50 feet is about as long as most school buses. Imagine meeting something the size of your school bus in the deep dark ocean and you might get an idea what it is like to meet a squid.Over the centuries, many squid specimens have been found, but it's hard to get an idea of how the squid lives because it typically cruises in the deepest depths of the ocean. We know that the giant squid's main predator is the sperm whale. We know this because bits of giant squid have been found in the stomachs of sperm whales. We also know they feed on deep-sea fish and other squid. We know this because of all the giant squid that have washed ashore.The giant squid lives in all of the world's oceansthough few are found in the tropics or the Arctic waters. As a result, stories of giant squid were told among sailors for hundreds of years. These sightings must have been frightening and may be the source for the legend of the Krakena sea monster reputed to be as large as an islandcapable of eating an entire ship.Read the following text from the passage:Just recently a Japanese film crew managed to film a giant squid swimming in its natural habitat.What does this sentence imply about the filming of the giant squid?A. it became like a job for the crew.B.
