What are the partial products that resault from multiplying 15×32

Eva8 [605]

Answer:

Partial products are 300, 150, 20 and 10. The value of 15×32 is 480.

Step-by-step explanation:

We need to find the partial products of 15×32.

First write each number as the sum of their place values.

$15=10+5$

$32=30+2$

Now, write 10 and 5 in first row, and 30 and 2 in first column as shown below:

10 5

30 30×10=300 30×5=150

2 2×10=20 2×5=10

Therefore partial products are 300, 150, 20 and 10.

Add these partial product to get the value of product.

$15\times 32 = 300+150+ 20+10$

$15\times 32 = 480$

The value of 15×32 is 480.

ladessa [460]

Answer:

<em> The 90% confidence interval for the population proportion is</em>

<em>(0.10872, 0.19128)</em>

Step-by-step explanation:

<u><em>Explanation:</em></u>-

<u><em>Step(i)</em></u>:-

Given data A random sample of 200 e-mail messages was selected. Thirty of the messages were not business related

Given random sample size 'n' = 200

Given Thirty of the messages were not business related

let 'x' = 30

<em>Probability of the messages were not business related or proportion</em>

<em></em> $p = \frac{x}{n} = \frac{30}{200} = 0.15$ <em></em>

<u><em>Step(ii)</em></u><em>:-</em>

<em>The 90% confidence interval for the population proportion is</em>

$(p - Z_{0.10} \sqrt{\frac{p(1-p)}{n} } , p + Z_{0.10} \sqrt{\frac{p(1-p)}{n} } )$

Level of significance ∝ = 0.90 or 0.10

The critical value Z₀.₁₀ = 1.645

<em>The 90% confidence interval for the population proportion is</em>

$( 0.15-1.645 \sqrt{\frac{0.15(1-0.15)}{200} } , 0.15 +1.645 \sqrt{\frac{0.15(1-0.15)}{200} } )$

on calculation, we get

(0.15 - 0.04128 , (0.15 + 0.04128)

(0.10872, 0.19128)

<u><em> Conclusion:-</em></u>

<em> The 90% confidence interval for the population proportion is</em>

<em>(0.10872, 0.19128)</em>

<em></em>
