<h3>What are rational numbers?</h3>

Rational numbers are numbers that can be expressed as the ratio of two integers. These numbers are in the form of p/q, where p and q can be any integer and q ≠ 0.

Therefore, the rational numbers between -5 and -4 are as follows:

-4.2
- 4.8
- 4.4
- 4.6

Note the numbers are between -5 and -4.

maria [59]

The inequality will be:

$x\geq 200$

Step-by-step explanation:

We need to write the inequality for the condition:

To get the 10% discount, a shopper must spend at least $200.Use d to represent the spending (in dollars) of a shopper who gets the discount.

Solution:

A person will get 10% discount if he spends $200 or more

Let x represents the amount that the shoppers will spend on shopping.

at least spend means the shoppers should spend $200 or more on the shopping to get the discount.

The inequality will be:

$x\geq 200$

A major metropolitan newspaper selected a simple random sample of 1,600 readers from their list of 100,000 subscribers.

Tpy6a [65]

Answer: $(0.36845,\ 0.43155)$

Step-by-step explanation:

Let p be the population proportion of readers who would like more coverage of local news.

As per given , we have

sample size :=1600

sample proportion : $\hat{p}=40\%=0.40$

The confidence interval for population proportion is given by :-

$\hat{p}\pm z^* \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

From z-table ,

For 99% confidence interval the z-value is 2.576.

Substitute all the values in the above formula , we get

The 99% confidence interval for the proportion of readers who would like more coverage of local news as

$0.40\pm(2.576) \sqrt{\dfrac{0.40(1-0.40)}{1600}}$

$0.40\pm(2.576) \sqrt{\dfrac{0.24}{1600}}$

$0.40\pm(2.576) \sqrt{0.00015}$

$0.40\pm(2.576) (0.0122474487139)$

$0.40\pm0.03155$

$(0.40-0.03155,\ 0.40+0.03155)=(0.36845,\ 0.43155)$

Hence, the 99% confidence interval for the proportion of readers who would like more coverage of local news is $(0.36845,\ 0.43155)$ .

Find the critical value of x2 based on the given information H1 >3.5 n=14 a=0.05

egoroff_w [7]

Answer:

The degrees of freedom are given by:

$df = n-1=14-1=13$

The significance level is $\alpha=0.05$ and then the critical value can be founded in th chi square table we need a quantile that accumulates 0.05 of the area in the right tail of the distribution and for this case is:
