Answer:

Below.

Step-by-step explanation:

35% as a decimal can be written as 0.35. Because it is 0.35 out of 1.00 or 0.35%.

As a fraction, you could write it as 35/100 because its 0.35 or 35/100

Answer:

decimal =0.35 and fraction= 7/20

Step-by-step explanation:

For removing percentage sign , divide by 100 so 35% becomes 35/100 and for converting it into decimal just add a decimal point before 35 since there is 100 in the denominator so it becomes 0.35 .

For converting 35% into fraction just remove the percentage first by dividing by 100 so it becomes 35/100 and take out a factor of 5 common from both numerator and denominator so 35/100 becomes 7/20 .

Step-by-step explanation:

9*(9+15)=8*(8+x)

9*(24)=8(x+8)

216=8x+64

216-64=8x+64-64

152=8x

152/8=8x/8

Andreas93 [3]

Answer:

$0.192 - 1.645\sqrt{\frac{0.192(1-0.192)}{250}}=0.151$

$0.192 + 1.645\sqrt{\frac{0.192(1-0.192)}{250}}=0.233$

Step-by-step explanation:

Information given

$X= 48$ number of people who rent their home

$n= 250$ represent the sample size

$\hat p =\frac{48}{250}= 0.192$ represent the proportion of people who rent their home

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by $\alpha=1-0.90=0.1$ and $\alpha/2 =0.05$ . And the critical value would be given by:
