Answer:

20% chance.

Step-by-step explanation:

If you do not know the formula, here is a quick intuitive method.

Construct the sample space in a square with 4 divisions

split one side into 1/2 and 1/2 and the other side into

.4 and .6

You can easily see that the day that it will rain on both days is .2 (1/2*.4)

or 20%

HELPS PLS ryad borrowed $1450 and made 18 payment of $95.25 how much did he pay in interest?
BaLLatris [955]
First calculate total payments
18×95.25=1,714.5

After that to find the interest you just subtract the amount borrowed from the total payments
Interest=1,714.5−1,450=264.5

Hope it helps!

(a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their wate
Anon25 [30]

Answer:

The margin of error (E)  =0.49

Step-by-step explanation:

Given,

 mean \bar{x}=6.88

 standard deviation \sigma=1.90

 sample size n=41

90\% \quad \text{confidence interval}

Critical value =\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}]  

                                                =1-0.90

                                        \Rightarrow \alpha=0.1

Critical value =\frac{z_{0.1}}{2}

                      =z_{0.05}

                      =1.645

The margin of error (E)  =\frac{z_\alpha}{2} \times\frac{\sigma}{\sqrt{n} }

                                       =1.645\times\frac{1.90}{\sqrt{41} }

                                       =0.49

Hence, The margin of error (E) =0.49
