How do I do a question 5* “I, J, k, and L
7nadin3 [17]

Answer:

Step-by-step explanation:

5 (i)  243 ÷x = -81

243 ÷ -81 = x

x = -3

5 (j)  50 ÷ x = -50

    50 ÷ -50 = x

       x = -1

5(k)   -92 * x = 184

                 x = 184 ÷  -92

                 x = -2

5(l)    -800 ÷x = -20

       -800 ÷ -20 = x

       x = 40

Compute the standard deviation of the data set. Round to the nearest hundredth, if needed.
Mkey [24]
Standard deviation is calculated by the square root of the variance. Now, how do we solve the variance? The variance is the <span>average of the </span>squared differences from the Mean. Calculating the variance, we can obtain a standard deviation of <span>3.74. Therefore, the correct answer is option A.</span>

I don’t understand please help!
nikklg [1K]

Answer:

x > 10/3

x will always be greater that 10/3 never the same nor less.

Step-by-step explanation:

3/5x + 1/3 < 4/5x - 1/3

3/5x - 4/5x + 1/3 < -1/3

-1/5x + 1/3 < -1/3

-1/5x < -1/3 - 1/3

-1/5x < -2/3

-1/5x/-1 < -2/3/-1   (Since it is both divided by a negative the sign switches, the sign also switches with multiplication. *Note: it only switches if it is negative!*)

1/5x > 2/3

5 • 1/5x > 2/3 • 5

x > 2/3 • 5/1

x > 10/3
