Rita = 2500

ExtremeBDS [4]

Let the price at which she sells the hi-fi set be x ~

$\huge \bf༆ Answer ༄$

The Money that she lose at the end of 2 years :

$\sf \: 2500 - x$

Loss percentage is equal to :

$\sf \dfrac{2500 -x }{2500} \times 100 = 20$

$\sf \dfrac{2500 - x}{25} = 20$

$\sf2500 - x = 20 \times 25$

$\sf2500 - x = 500$

$\sf - x = 500 - 2500$

$\sf - x = - 2000$

$\sf x = 2000$

So, the money she end up getting after selling that hi-fi set is 2500, that is also the money She have at the end of the two years ~

An automobile owner found that 20 years ago, 72% of Americans said that they would prefer to purchase an American automobile. He

LenaWriter [7]

Answer:

$z=\frac{0.884 -0.72}{\sqrt{\frac{0.72(1-0.72)}{43}}}=2.395$

Now we can find the p value taking incount that we are using a bilateral test

$p_v =2*P(z>2.395)=0.01662$

Since the p value is lower than the significance level of 0.1 we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of Americans that they would prefer an American automobile is significantly different from 0.72 and then the claim is correct

Step-by-step explanation:

Information given

n=43 represent the random sample taken

X=38 represent the Americans who they would prefer an American automobile

$\hat p=\frac{38}{43}=0.884$ estimated proportion of Americans that they would prefer an American automobile

$p_o=0.72$ is the value that we want to check

$\alpha=0.1$ represent the significance level

z would represent the statistic

$p_v$ represent the p value

Hypothesis to test

We want to verify if the percentage of Americans that they would prefer an American automobile today differs from 72%, then the system of hypothesis are:

Null hypothesis: $p=0.72$

Alternative hypothesis: $p \neq 0.72$

The statistic is given by:

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

Replacing the data given we got:

$z=\frac{0.884 -0.72}{\sqrt{\frac{0.72(1-0.72)}{43}}}=2.395$

Now we can find the p value taking incount that we are using a bilateral test

$p_v =2*P(z>2.395)=0.01662$

Since the p value is lower than the significance level of 0.1 we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of Americans that they would prefer an American automobile is significantly different from 0.72 and then the claim is correct

Benito wrote the equations shown about the figure. Explain Benito’s errors.

Whitepunk [10]

Answer:

Benito's error was stating that the correspongind sides and angles are equal (=) instead of stating that they are congurent (≅).

Explanation:

In geometry two different figures (segments, angles, polygons ,...) are not said to be equal but congruent.

Congruent means that they have the same measure but not that they are equal in other senses.

The use of equal is applied to numbers or variables),so you can tell x = 2, 3 = 3, A = πr², but you should not say segment AB is equal to segment BC. Instead you say segment AB ≅ segment BC, which is segment AB is congruent to segment BC.

Of course, you still can use the word equal (symbol =) if you state that you are talking about measures.

This also can help you

Correct: segment AB ≅ segment BC

Correct: legth of segment AB = length of segment BC

Incorrect: segment AB = segment BC

Segment AB and segment BC are not equal because they are two different segments. They are congruent because they have the same length.

Note: the bars shown over the letters AB, BC, AD, DC, mean segment.
