students are painting a mural so far the mural is painted 1/4 blue ,2/8 red and 3/12 green use fraction strips to determine how

Fofino [41]

------------------------------------------------------------------------------------
Reduced (simplify) all factions if possible
------------------------------------------------------------------------------------

(1/4 cannot be reduced)
1/4 = 1/4

(divided by 2 for both numerator and denominator)
2/8 = 1/4

(divide by 3 for both numerator and denominator)
3/12 = 1/4

------------------------------------------------------------------------------------
Find combined fraction of the mural that has been painted.
------------------------------------------------------------------------------------
1/4 + 1/4 + 1/4 = 3/4

------------------------------------------------------------------------------------
Answer: 3/4 of the mural has been painted.

Answer:

tan p = 5/12.

tan p = cot r.

Step-by-step explanation:

RQ = √(13^2 - 12^2)

= √25

= 5.

tan p = opposite side / adjacent side = 5/12.

cot r = adjacent side / opposite side = 5/12.

tan p = cot r.

Note that the proportion of students who went Home for winter break was 0.35 (or 35%). Briefly explain why it would not be appro

tensa zangetsu [6.8K]

Answer:

Is not appropiate to refer a estimation or a statistic as a paramter because the statistic just give informaation about the sample selected and not about all the population of interest. What we can do is inference with this sample proportion or confidence intervals in order to see on what limits our real parameter of interest p lies.

Step-by-step explanation:

Description in words of the parameter p

$p$ represent the real population proportion of students who went Home for winter break

$\hat p$ represent the estimated proportion of students who went Home for winter break

n is the sample size selected

The population proportion have the following distribution

$p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

Solution to the problem

For this case we assume that the proportion given 0.35 is an estimation for the real parameter of interest p, that means $\hat p = 0.35$

On this case the estimated proportion is calculated from the following formula:

$\hat p = \frac{X}{n}$

Where X are the people in the sam with the characteristic desired (students who went Home for winter break) and n the sample size selected.
