Answer:

LCM :

6 x 1 = 6

6 x 2 = 12

6 x 3 = 18

6 x 4 = 24

Meanwhile

4 x 1 = 4

4 x 2 = 8

4 x 3 = 12

4 x 4 = 16

4 x 5 = 20

4 x 6 = 24

The LCM of 6 and 4 is 12

HCF:

36 : 1,2,3,4,6,9,12,36

24 : 1,2,3,4,6,8,12,24

HCF of 36 and 24 is 12

So therefore Hussein is correct because both the LCM and HCF is 12

Yes he is correct.
Explanation:
Because 36 & 24 has a hcf (highest common factor) of 12
And because 6 & 4 has lcm (least common multiple) of 12
To find out the lcm just go through their time table and find a common least multiple and to find out hcf just go through their time table and find a common highest factor.
Hope this helps! :)

Using the t-distribution, it is found that since the p-value of the test is of 0.0302, which is less than the standard significance level of 0.05, the data provides convincing evidence that the average food intake is different for the patients in the treatment group.

At the null hypothesis, it is tested if the consumption is not different, that is, if the subtraction of the means is 0, hence:

$H_0: \mu_1 - \mu_2 = 0$

At the alternative hypothesis, it is tested if the consumption is different, that is, if the subtraction of the means is not 0, hence:

$H_1: \mu_1 - \mu_2 \neq 0$

Two groups of 22 patients, hence, the standard errors are:

$s_1 = \frac{45.1}{\sqrt{22}} = 9.6154$

$s_2 = \frac{26.4}{\sqrt{22}} = 5.6285$

The distribution of the differences is has:

$\overline{x} = \mu_1 - \mu_2 = 52.1 - 27.1 = 25$

$s = \sqrt{s_1^2 + s_2^2} = \sqrt{9.6154^2 + 5.6285^2} = 11.14$

The test statistic is given by:

$t = \frac{\overline{x} - \mu}{s}$

In which $\mu = 0$ is the value tested at the null hypothesis.

Hence:

$t = \frac{25 - 0}{11.14}$

$t = 2.2438$

The p-value of the test is found using a two-tailed test, as we are testing if the mean is different of a value, with t = 2.2438 and 22 + 22 - 2 = 42 df.

Using a t-distribution calculator, this p-value is of 0.0302.

Since the p-value of the test is of 0.0302, which is less than the standard significance level of 0.05, the data provides convincing evidence that the average food intake is different for the patients in the treatment group.

What is the final amount if 468 is increased by 8% followed by a further 9%

bixtya [17]

Answer:

The final amount is 550.93.

Step-by-step explanation:

Here, the given amount is 468.

Now 8% of the given amount is $\frac{8}{100} \times 468 = 37.44$

⇒ 8% of 468 = 37.44

So, the New amount = Initial Amount + 8% increase

= 468. + 37.44 = 505.44

Now 9 % of the new amount 505.44 is

[tex]\frac{9}{100} \times 505.44 = 45.4896/tex]

⇒ 9% of 505.44 = 45.4896

So, the Final amount = New Amount + 9% increase

= 505.44 + 45.4896 = 550.93

Hence, final amount is 550.93.
