Answer:

180 grams

Step-by-step explanation:

grams of dark chocolate= 200 % cocoa =60%

Grams of milk chocolate: 200 % cocoa=30%

Amount of cocoa in mixture:

(proportion of milk chocolate+ dark chocolate)

(30% of 200)+60% of 200)

(0.3* 200)+(0.6 *200)

60+120

=180 grams

Answer:

$45\%$

Step-by-step explanation:

The 200g mixture of dark chocolate is 60% cocoa, meaning there are $200\cdot 0.6=120$ grams of cocoa in this mixture.

The 200g mixture of milk chocolate is 30% cocoa, meaning there are $200\cdot 0.3=60$ grams of cocoa in this mixture.

When mixed together there are a total of 200+200=400 grams of content. Of these 400 grams, 120+60=180 of them are cocoa.

Thus, the concentration of cocoa in the resulting mixture is:

$\frac{180}{400}=\fbox{$45\%$}$

A study was performed with a random sample of 3000 people from one church. What population would be appropriate for generalizing

Reil [10]

The population would be set of all Christians of that particular church from where the random samples is collected.

According to the questions,

A study was performed with a random sample 3000 people from one church. In order to find appropriate population for generalizing conclusions

The population would be set of all Christians of that particular church from where the random samples is collected.

This is because random samples is collected only from the particular church, so its generalization can only be the possible to large population of that church.

we can generalize to whole of that church because it is given that there was no bias is introduced.

Hence, the population would be set of all Christians of that particular church from where the random samples is collected.

Write five other iterated integrals that are equal to the given iterated integral. 8 0 x2 0 y f(x, y, z) dz dy dx 0

mash [69]

An iterated integral is the outcome of taking integrals toward a function of more than one variable in such a way that part of the variables is treated as constants for each of the integrals.

From the given parameters, we are to write out five iterations for a triple integral;

$\mathbf{\int ^8_0\ \int^{x^2}_{0} \ \int^y_0 \ \ f(x, y, z) \ dz dy dx }$
