Use the Empirical Rule to determine the percentage of candies with weights between 0.7 and 0.98 gram. ​Hint: x=0.84
Lubov Fominskaja [6]

Using the Empirical Rule, it is found that 95% of the candies have weights between 0.7 and 0.98 gram.

<h3>What does the Empirical Rule state?</h3>

It states that, for a normally distributed random variable:

  • Approximately 68% of the measures are within 1 standard deviation of the mean.
  • Approximately 95% of the measures are within 2 standard deviations of  the mean.
  • Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Researching this problem on the internet, we have that:

  • The mean is of 0.84.
  • The standard deviation is of 0.07.

Then 95% of the candies have weights between 0.7 and 0.98 gram, as:

  • 0.7 = 0.84 - 2 x 0.07.
  • 0.98 = 0.84 + 2 x 0.07.

|3w + 4| = 6w + 1 (absolute value equations. With work to explain it please..
sergiy2304 [10]

Answer:

w= 1 and w= -5/9

Step-by-step explanation:

Because you have an absolute value that means that there are 2 possibilities

either (3x +4) is positive or negative. Will work each case and that will give us the answers.

If (3x+4) is positive we have the equation

3w+ 4 = 6w +1 , subtract 3w from both sides

       4 = 6w-3w+1, subtract 1 from both sides

    4-1 = 6w-3w, combine like terms

      3 = 3w , divide both sides by 3

      1 = w

If (3x+4) is negative we have the equation

-(3w+ 4) = 6w +1 , distribute the negative sign in parentheses

  -3w -4 = 6w +1, add 3w and subtract 1 from both sides of the equation

      -4 -1 = 6w +3w, combine like terms

          -5 = 9w , divide both sides by 9

    (-5/9) = w

d.-312

2.

a. y=3

b.x=-3

c.z=4

d. y=4.33

Step-by-step explanation:

1

a.Solution:

-32÷8×2+2+1

=-4×2+2+1

=-8+2+1

=-8+3

=-5

b. Solition:

53×9+109×53

=5300

c. Solution:

-891

d. Solution:

-63×12+12×37

=-756+444

-312

2.

a. Solution:

5y-3+3=-18+3

5y=-15

y=-15/5

y=3

b. Solution:

-3x-9+9=0+9

-3x=9

x=9/-3

x=-3

c. Solution:

4+3-3(z-8-3)=-23-3

4(z-5)=-20

4z-20=-20

4z-20+20=-20+20

4z

z=4

d. Solution:

1-2+2(y-4+2)=5+2

3(y-2)=7

3y-6=7

3y-6+6=7+6

3y=13

y=13/3

y=4.33
