Mathematics

Katena32 [7]3 years ago
5 0

Answer:

Step-by-step explanation:

Let the number of blue marbles be x

The number of green marbles = 3x - 2

Total marbles= 18

x + 3x -2 = 18

4x - 2 = 18

     4x = 18+2

      4x = 20

x =20/4

x =5

The number of blue marbles = 5

The number of green marbles = 3*5 - 2 = 15 -2 = 13

A value two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean.
Alexxandr [17]

Answer:

A value two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean.

Step-by-step explanation:

Standard deviation is a quantitative measure of the variability of traits of the subjects in a given population. These traits can range from age, height, weight e.t.c. This deviation is brought about by extreme or abnormal conditions, which is the reason why two deviations is more likely to occur than three deviations.

Moreover, going by the provisions of the empirical rule, If data comes from a population that is approximately symmetrical;

95% of the data will fall within two standard deviations.

99.7% will fall within three standard deviations

Find the attachment below.

Nevertheless, in a symmetrical distribution most of the data values fall around the mean. Two standard deviations is closer to the mean than 3 standard deviations hence more likely to occur.

Please help. The correct and best answer gets brainiest! 29 points!!
attashe74 [19]

Answer:(15, 100)

Step-by-step explanation:

first find the coordinates of the point above (3, 20)

you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40

so the coordinate would be (6, 40)

now subtract (6, 40) by (3, 20)

6-3= 3

40- 20= 20

you get the first coordnites which is what you add (12,80) to

12 +3= 15

80+ 20= 100

you get the coordinates (15, 100)

Last year 40 people adopted a mantee through Fia's foundation. This year 30% more people adopted a manatee . How many people ado
Charra [1.4K]

Number of people adopted a mantee through Fia's foundation = 40

30% more are people adopted a manatee

Number of people adopted = 30% of 40 = (0.30)(40) = 12

People adopted a manatee this year = number of people + 30% of 40

People adopted a manatee this year = 40 + 12

People adopted a manatee this year = 52
