So to get from 4 to 8 you multiply by 2. To get from 8 to 16 you multiply by 2. So for the missing number, 10 times 2=20. The missing number should be 20. To check our work, 20 times 2 equals 40. So the missing number is 20. Hope this helps! ;)

matrenka [14]

Answer:

The Answer is 29/18 and in mixed form it is 1 11/18

Step-by-step explanation:

Steps for adding fractions

Find the least common denominator or LCM of the two denominators:

LCM of 9 and 6 is 18

Next, find the equivalent fraction of both fractional numbers with denominator 18

For the 1st fraction, since 9 × 2 = 18,

7 × 2

9 × 2

Likewise, for the 2nd fraction, since 6 × 3 = 18,

5 × 3

6 × 3

Add the two like fractions:

14 + 15

= 29/18

So, 7/9 + 5/6 = 29/18

In mixed form: 1 11/18

As a manager for an advertising company, you must plan a campaign designed to increase Twitter usage. A recent survey suggests t

kolbaska11 [484]

Given:
Sample proportion = 85% = 0.85.
Confidence level (CL) = 90%.
Confidence interval (CI) $\hat{p} \pm z^{*} \sqrt{ \frac{\hat{p}(1-\hat{p})}{n} } \\ where \\ n=sample\, size \\ z^{*}=1.645 \, at \, 90\% \, CL$

We want the confidence interval to be 5% or 0.05. Therefore
$0.85 - 1.645 \sqrt{ \frac{0.85(1-0.85)}{n} }=0.05 \\ 0.85 - \frac{0.5874}{ \sqrt{n} } =0.05 \\ \frac{0.5874}{ \sqrt{n} }=0.8 \\ \sqrt{n} = .7342 \\ n=0.54$

Because this number is less than 1, a default sample size of 30 (for the normal distribution) is recommended.
