Mathematics

Answer:

396

Step-by-step explanation:

First, find the prime factorization of each number.

44 = 2^2 * 11

36 = 2^2 * 3^2

For the LCM, you need non-common factors and common factors with the larger exponent. Then you multiply together all the factors you use.

2 is a common factor. Both numbers have 2^2, so choose 2^2.

3 is not common. Use 3^2.

11 is not common. Use 11.

LCM = 2^2 * 3^2 * 11 = 396

36 is 4% of what number

QveST [7]

Answer:

900

Step-by-step explanation:

We have, 4% × x = 36

or ----- × x = 36

100

Multiplying both sides by 100 and dividing both sides by 4,

100

we have x = 36 × -------

x = 900

If you are using a calculator, simply enter 36×100÷4, which will give you the answer

The estimate of the population proportion should be within plus or minus 0.02, with a 90% level of confidence. The best estimate

Rudiy27

Answer:

The sample size required is 910.

Step-by-step explanation:

The confidence interval for population proportion is:

$CI=\hat p\pm z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }$

The margin of error is:

$MOE=z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }$

Given:

$\hat p = 0.16\\MOE= 0.02\\Confidence\ level =0.90$

The critical value of <em>z</em> for 90% confidence level is:

$z_{\alpha /2}=z_{0.10/2}=z_{0.05}=1.645$ *Use a standard normal table.

Compute the sample size required as follows:

$MOE=z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }\\0.02=1.645\times \sqrt{\frac{0.16(1-0.16)}{n} }\\n=\frac{(1.645)^{2}\times 0.16\times (1-0.16)}{(0.02)^{2}} \\=909.2244\\\approx910$

Thus, the sample size required is 910.
