9. Which of the following is TRUE? ( 5 points) a. For a data set with mean = 25 pounds and Standard Deviation = 2 pounds then 95

pychu [463]

Answer:

For a data set with mean = 25 pounds and Standard Deviation = 3 pounds then 95% of the data is between 19 pounds and 31 pounds.

Step-by-step explanation:

1 ) 68% of the data lies within 1 standard deviation of mean

This means 68% of data lies between: $\mu-\sigma$ to $\mu+\sigma$

2) 95% of the data lies within 2 standard deviation of mean

This means 95% of data lies between: $\mu-2\sigma$ to $\mu+2\sigma$

3) 99.7% of the data lies within 3 standard deviation of mean

This means 99.7% of data lies between: $\mu-3\sigma$ to $\mu+3\sigma$

Now,

95% of the data lies within 2 standard deviation of mean :

For Mean = $\mu = 25$

Standard deviation = $\sigma = 2$

So, 95% of data lies between: $25-2(2)$ to $25+2(2)$

95% of data lies between: $21$ to $29$

For Mean = $\mu = 25$

Standard deviation = $\sigma = 3$

So, 95% of data lies between: $25-2(3)$ to $25+2(3)$

95% of data lies between: $19$ to $31$

So, Option D is true

For a data set with mean = 25 pounds and Standard Deviation = 3 pounds then 95% of the data is between 19 pounds and 31 pounds.

Can somone help me with this

SpyIntel [72]

Answer:

(4,-6)

Step-by-step explanation:

2x + 2y = -20

x + y = -10

y = -x-10

5x-5y = -10

x-y=-2

x-(-x-10) = -2

2x-10 = -2

2x= 8

x = 4

4 + y = -10

y = -6

What is the solution to the equation1 over the square root of 8 = 4(m − 2)? (1 point)

kupik [55]

Rationalize the denominator, divide by 4, add 2.
$\dfrac{1}{\sqrt{8}}=4(m-2)\\\\ \sqrt{\dfrac{2}{16}}=4(m-2)\\\\ \dfrac{\sqrt{2}}{4\cdot 4}=m-2\\\\ m=2+\dfrac{\sqrt{2}}{16}$
