5 0

Answer:

Step-by-step explanation:

The tenths place is on the other side of the decimal so you have to star from 3. if the 3 was the number 5 or higher you would round the 9 up to ten, but since it is lower you leave the 9 alone and then move on to the next number which is 5. The 5 would be rounded up to 6 because the 9 next to it is higher than 5. So far you have 0.6. looking at the 0 we would round up to 1 because the 6 is higher than 5. the result is 1.0 or 1.

Absolute value of |x|-2=5

Stells [14]

Answer:

x = ± 7

|-7|-2=5

|7|-2=5

± means positive or negative

Step-by-step explanation:

|x|-2=5

Get x by itself by adding 2 to both sides.

x - 2 + 2= 5 + 2

-2 + 2 cancels out

x = 5 + 2

x = 7

Absolute value is how far a number is from 0.

x can be either positive or negative.

A veterinarian weighed a sample of 666 puppies. Here are each of their weights (in kilograms): 1, 2, 7, 7, 10, 151,2,7,7,10,151,

rjkz [21]

Answer:

The standard deviation of the weight, σ, is approximately 4.73 kg

Step-by-step explanation:

The weights of the six puppies are;

$x_i$ = 1, 2, 7, 7, 10, and 15

The number of puppies, n = 6

Therefore, we have;

The mean = μ = ∑x/n = (1 + 2 + 7 + 7 + 10 + 15)/6 = 7

The standard deviation, σ, is given as follows;

$\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{n}}$

By substituting, we have;

$\sigma =\sqrt{\dfrac{ \left (1-7 \right )^{2} + \left (2-7 \right )^{2} + \left (7-7 \right )^{2} + \left (7-7 \right )^{2} + \left (10-7 \right )^{2} + \left (15-7 \right )^{2} }{6}}$

Simplifying gives;

$\sigma =\sqrt{\dfrac{ \left (-6 \right )^{2} + \left (-5 \right )^{2} + \left (0 \right )^{2} + \left (0 \right )^{2} + \left (3 \right )^{2} + \left (8 \right )^{2} }{6}} =\sqrt{\dfrac{ 36 + 25 + 0 +0+ 9 + 64 }{6}}$

$\sigma =\sqrt{\dfrac{ 134 }{6}} = \sqrt{\dfrac{67}{3} } \approx 4.72582$

The standard deviation of the weight, σ ≈ 4.73 kg to two decimal places.
