Initial cost of vacuum cleaner is = 248
tax is 6% = 6/100. 248 x 0.06 = 14.88
Thus, final cost of vacuum cleaner is 248 + 14.88 =  $262.88
That is one expensive vacuum cleaner

The answer is $262.88

First you need to multiply the 6% from $248
$248x.06%= $14.88

Now you know that 6% of $248 is $14.88

Now you just need to add the $14.88 to the Orignal price of the vacuum $248

$248+$14.88= $262.88 <---- Answer

In a poll of 1000 adults in July​ 2010, 540 of those polled said that schools should ban sugary snacks and soft drinks. Complete
erastova [34]

Answer:

z=2.53  

p_v =P(z>2.53)=0.0057  

The p value obtained was a very low value and using the significance level given \alpha=0.05 we have p_v so then we have enough evidence to reject the null hypothesis, and we can say that at 5% of significance, the proportion of adults who support a ban on sugary snacks and soft​ drinks  is more than 0.5 or 50%.

Step-by-step explanation:

1) Data given and notation

n=1000 represent the random sample taken

X=540 represent the adults that said that schools should ban sugary snacks and soft drinks

\hat p=\frac{540}{1000}=0.54 estimated proportion of adults that said that schools should ban sugary snacks and soft drinks

p_o=0.5 is the value that we want to test

\alpha=0.05 represent the significance level

Confidence=95% or 0.95

z would represent the statistic (variable of interest)

p_v represent the p value (variable of interest)  

2) Concepts and formulas to use  

We need to conduct a hypothesis in order to test the claim that majority of adults​ (more than​ 50%) support a ban on sugary snacks and soft​ drinks, the system of hypothesis are:  

Null hypothesis:p\leq 0.5  

Alternative hypothesis:p > 0.5  

When we conduct a proportion test we need to use the z statistic, and the is given by:  

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

The One-Sample Proportion Test is used to assess whether a population proportion \hat p is significantly different from a hypothesized value p_o.

3) Calculate the statistic  

Since we have all the info requires we can replace in formula (1) like this:  

z=\frac{0.54 -0.5}{\sqrt{\frac{0.5(1-0.5)}{1000}}}=2.53  

4) Statistical decision  

It's important to refresh the p value method or p value approach . "This method is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.  

The significance level provided \alpha=0.05. The next step would be calculate the p value for this test.  

Since is a one side right tailed test the p value would be:  

p_v =P(z>2.53)=0.0057  

So the p value obtained was a very low value and using the significance level given \alpha=0.05 we have p_v so then we have enough evidence to reject the null hypothesis, and we can say that at 5% of significance, the proportion of adults who support a ban on sugary snacks and soft​ drinks  is more than 0.5 or 50%.

Runners in the half marathon entered in three waves. There were 341 runners in the first wave, 295 runners in the second wave, a
Natasha_Volkova [10]
190 runners would not have finished the race.

If you add up all the waves, there were 952 total runners.

If 7/8 finished the race, then that means that 1/8 did not finish the race.

Just multiply 1/8 by 952 to get the amount that did not finish.
It would be 190.

A bee flies 25 m north of the hive then 10 m east 5 m west and 10 m south. How far north and east of the hive is it now? Explain
mafiozo [28]

Answer:

20 meters north.

Step-by-step explanation:

(I did it on a paper not to lose track.) First we go 25 north. Then ten east. Five south. And 10 west again. So in East/West we didn't move but we moved 5 down/south so we are still at twenty. If you don't understand still draw it on a paper.
