Apply the distributive property using the greatest common factor to write an equivalent expression. Enter your answers in the bo

Lilit [14]

Solution:

0.3 × 2.7

Using Distributive property of multiplication with respect to subtraction the value of multiplication of two rationals or two decimals

⇒0.3 × (3-0.3)

⇒ 0.3 × 3 - 0.3 × 0.3

⇒ 0.9 - 0.09

= 0.81

H C F of 0.3 and 2.7 is 0.3.

The Equivalent of product of 0.3 × 2.7 are

1.→0.9 × 0.9

2.→→ 3 × 0.27

The mayor of a town has proposed a plan for the construction of a new community. A political study took a sample of 800 voters i

Hunter-Best [27]

Answer:

A political strategist wants to test the claim that the percentage of residents who favor construction is more than 30%, so then that represent our claim and needs to be on the alternative hypothesis.

Based on this the correct system of hypothesis are:

Null hypothesis: $p \leq 0.3$

Alternative hypothesis $p >0.3$

Step-by-step explanation:

We have the following info given from the problem:

$n= 800$ the random sample of voters selected from the town

$\hat p = 0.34$ represent the proportion of residents favored construction

$p_o = 0.30$ represent the value desired to test.

A political strategist wants to test the claim that the percentage of residents who favor construction is more than 30%, so then that represent our claim and needs to be on the alternative hypothesis.

Based on this the correct system of hypothesis are:

Null hypothesis: $p \leq 0.3$

Alternative hypothesis $p >0.3$

And in order to test this hypothesis we can use a one sample z test for a population proportion and the statistic would be given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

And with the data given we have:

$z=\frac{0.34 -0.3}{\sqrt{\frac{0.3(1-0.3)}{800}}}=2.469$
