Answer:

15 years

Step-by-step explanation:

4p=60

To solve this, use the inverse operation of multiplication, division, to counter the multiplication. To do this divide both sides by 4. 4p/4=1p or p. 60/4=15.

Therefore, Peter is 15 years old.

liq [111]

Answer:

s^2 = \frac{(1.48-1.502)^2 +(1.45-1.502)^2 +(1.54-1.502)^2 +(1.52-1.502)^2 +(1.52-1.502)^2}{5-1} =0.00132

And for the deviation we have:

s= \sqrt{0.00132}=0.0363

And that value represent the best estimator for the population deviation since:

E(s) =\sigma

Step-by-step explanation:

For this case we have the following data:

1.48,1.45,1.54,1.52,1.52

The first step for this cae is find the sample mean with the following formula:

\bar X =\frac{\sum_{i=1}^n X_}{n}

And replacing we got:

\bar X= \frac{1.48+1.45+1.54+1.52+1.52}{5} = 1.502

And now we can calculate the sample variance with the following formula:

s^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}

And replacing we got:

s^2 = \frac{(1.48-1.502)^2 +(1.45-1.502)^2 +(1.54-1.502)^2 +(1.52-1.502)^2 +(1.52-1.502)^2}{5-1} =0.00132

And for the deviation we have:

s= \sqrt{0.00132}=0.0363

And that value represent the best estimator for the population deviation since:

E(s) =\sigma

In the ellipse, if c=6cm, and b=8cm, what is the length of the major axis?
kondor19780726 [428]

Answer:

Option B). 10 cm

Step-by-step explanation:

Distance between center and the focus of an ellipse is given by the formula,

c² = a² - b²

where, a = length of the major axis

b = length of the minor axis

and c = distance between focus and center

If c = 6 cm, b = 8 cm,

6² = a² - 8²

a² = 6² + 8²

a² = 36 + 64

a² = 100

a = 10 cm

Therefore, length of the major axis is 10 cm.

Option (B) is the answer.
