What are the integer solutions to the inequality below?

Mathematics

Dmitry [639]2 years ago
5 0

3 < 3x - 3 ≤ 2x + 2

Adding -3 to each side gives

0 < 3x - 6 ≤ 2x - 1

The left inequality says

0 < 3x - 6   ⇒   3x > 6   ⇒   x > 2

while the right inequality says

3x - 6 ≤ 2x - 1   ⇒   x ≤ 5

Then the solutions belong to the interval 2 < x ≤ 5 and contains only the integers x = 3, x = 4, and x = 5.

I need help solving a system of linear equation, and it says to solve it by Substitution.
olga_2 [115]
2x - 3y = -24
x+ 6y = 18

you solve the first one by the x:

2x = -24 + 3y

x = (-24+3y)/2

then you substitute what you found in the other equation and you solve by y

(-24+3y)/2 + 6y = 18                   multiply everything by 2

-24 + 3y + 12y = 36

3y + 12y = 36 + 24

15y = 60

y = 60/15

y = 4

Good job! You found your y! :D

Now let's substitute the y in the first equation with 4:

2x - 3(4) = -24

2x - 12 = -24

2x = -24 + 12

2x = -12

x = -12/2

x= -6

Done!! ;) <span />

The correlation between height and weight for a certain breed of plant is found to be 0.75. What percentage of the variability i
WINSTONCH [101]

Answer:

The percentage of the variability in plant weight is NOT explained by height is  

      p = 43.75%

Step-by-step explanation:

From the question we are told that

      The correlation between height and weight is  r = 0.75

Generally the R-Squared  between height and weight is mathematically represented as

        R - square  =  r^2

substituting values

         R - square  =  0.75^2

         R - square  =  0.563

This R-Squared tells us the percentage of plant weight is accounted by height

and from the calculation we see that it is  56.3%

Now the percentage of plant weight that is not accounted by height is

          p =  100 - 56.3

          p = 43.75%
