The table shows the record low temperatures for several states. Graph the temperatures on a number line.
OlgaM077 [116]

Step-by-step explanation:

Please find the attachment.

We have been given a table that shows the record low temperatures for several states. We are asked to graph the temperatures on a number line.

First of all we will draw a number line going to infinity into both directions.  

To graph the given temperatures on number line let us arrange temperatures in less negative order.  

-34, -32, -30, -29, -27.  

Since we know that numbers with large negative values lie on the left at number line. Let us graph our large negative temperature on the left at our number line.      

We can see that -34 is the most negative temperature, therefore, it will be on the left most side of our number line.  

-27 is greatest of our given negative temperatures. -27 is less negative temperature than our other given low temperatures, therefore, it will lie on the right most side of our number line.  

Other temperatures will lie between these two values according to their temperatures.    

-32 is second large negative temperature after -34, therefore, it will lie on the right side of -34.

-30 will lie on the right side of -32 and -29 will lie on the right of -32.

Suppose a sample of 80 with a sample proportion of 0.58 is taken from a
Anvisha [2.4K]

Answer:

99.7% confidence interval is [0.4162,0.7437]

Step-by-step explanation:

The formula for a confidence interval for a population proportion is CI=\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} } where \hat{p} is the sample proportion, n is the sample size, and z^* is the critical score for the desired confidence level.

We are given a sample size of n=80 and a sample proportion of \hat{p}=0.58. Our critical score for a 99.7% confidence level would be z^*=normalcdf(0.9985,0,1)=2.9677

Therefore, the approximate 99.7% confidence interval for the population parameter is CI=\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }=0.58\pm 2.9677\sqrt{\frac{0.58(1-0.58)}{80} }=[0.4162,0.7438]

So we are 99.7% confident that the true population proportion is contained within the interval [0.4162,0.7437]

Your friend is going to buy a used car. The one he is considering costs $4000 and will lose value at a rate of 13% per year. How
guapka [62]

13% of $4000 is $520
If the $4000 car loses value at a rate of 13% each year for 3 years
$520 x 3 = $1560
Subtract this amount from $4000
$4000 - $1560 = $2440

<u>Answer: In 3 years, the used car will be worth $2440 in 3 years</u>

So 749.99-112.50=$637.49 and
637.49 • 7% or .07= 44.62 and
